The robots will be given the same opportunities as humans to feel and see the full spectra and thus be able to take greater responsibility for what they do. </b></p><div><img src="/en/departments/e2/news/Documents/ATR.jpg" alt="ATR.jpg" style="margin:5px;width:675px;height:450px" /><br />​Anthony Cavin with Per-Lage Götvall at Volvo.​​   Foto: Volvo Group Truck Operations<br /><br /></div> <div>This can be made possible as researchers at Chalmers and Volvo develop systems of artificial intelligence with cameras, in Volvo's factories, where information from the cameras is the robots' main source of information. Researchers from Chalmers have been working together with Volvo Group Truck Operations (GTO) for a long time and now the vision is starting to become reality.<strong><br /></strong></div> <div><br /></div> <div><strong>Flexible and advanced technology</strong></div> <div>Admittedly, self-driving trucks are no new news in the automotive industry, but so far, they generally use simple technology – such as following a magnetic loop or a strip of tape on the floor. The control and monitoring of the factory's material flows that Volvo Trucks now outlines will be significantly more flexible and advanced.</div> <div><br /></div> <div><img src="/en/departments/e2/news/Documents/Knut_Akesson_220608_5906.jpg" alt="Knut_Akesson_220608_5906.jpg" class="chalmersPosition-FloatLeft" style="margin:10px 5px;height:171px;width:245px" />“Fundamentally, it is the need for more environmentally friendly transport that drives the development”, says Knut Åkesson, Professor of Automation at the Department of Electrical Engineering at Chalmers University of Technology and the one who leads the work from Chalmers' side.</div> <div><br /></div> <div>Today, it is not a given which technology will replace the diesel engine, and within the Volvo Group, work is being done in parallel to develop several alternatives. Manufacturing trucks with several different powertrains in the same factory means that the amount of components required to manufacture them increases greatly.<span style="background-color:initial">This</span><span style="background-color:initial">, in turn, means that the need to improve the efficiency of internal transport</span></div> <img src="/en/departments/e2/news/Documents/P-L%20foto%202020-01-16_high.jpg" alt="P-L foto 2020-01-16_high.jpg" class="chalmersPosition-FloatRight" style="margin:5px;height:212px;width:160px" /><div><span style="background-color:initial"> increases.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">“H</span><span style="background-color:initial">ere we see that a type of self-driving transport robot can give us the flexibility to use the floor space in the factory in the best way and at the same time also give us the efficiency we must have in our internal transports”, says Per-Lage Götvall, Senior Research Leader at Volvo GTO and the one who leads the work within the Volvo Group.</span><span style="background-color:initial"><br /></span></div> <div><br /></div> <div>For several years, Knut Åkesson and his team have worked closely with the Volvo GTO to develop the GPSS (Generic Photogrammetry based Sensor System), image analysis using machine learning. A collaboration that has been very valuable and fun.</div> <div><br /></div> <div>If the work to develop the GPSS system and its transport robots is as successful as Volvo believes, it will mean a huge change in the factories' internal transport flows, from the traditional &quot;fishbone layout&quot; to more &quot;Just-in-time&quot;. The system is then expected to be implemented in most of Volvo's more than 30 factories worldwide.</div> <div><br /></div> <div><strong>Efficiency and safety</strong></div> <div>But it is not a trivial task to create a traffic system where, in the end, hundreds of self-driving transport robots will be able to function efficiently, safely, and friction-free in an environment where people and materials are constantly in motion.</div> <div><br /></div> <div>&quot;Compared to normal road traffic, the factory floor still constitutes a limited and controlled environment and just like in traffic, where common rules make everything work, similar principles can also work in factories. This means that all transport robots can be controlled and coordinated by an &quot;omniscient&quot; system”, Knut Åkesson explains.</div> <div><br /></div> <div>Planning all material transport in time and space, based on what production requires, is an important part of the system. In addition, it will prevent transport robots from driving in each other's way.</div> <div><br /></div> <div>“But then there are all the dynamic obstacles, in the form of people and traditional forklifts, which the system cannot control&quot;, Knut Åkesson adds.</div> <div><br /></div> <div><strong>Traffic monitoring systems and machine learning</strong></div> <div><strong><img src="/en/departments/e2/news/Documents/GPSS_pricipls.png" alt="GPSS_pricipls.png" style="margin:10px 20px" /><br /></strong><span style="background-color:initial">This is where the GPSS technology comes in. The idea is that the cameras in the ceiling should detect and classify all static and moving obstacles on the factory floor and thus guide the transport robots to their destination without collisions and accidents. The cameras become the joint &quot;eyes&quot; of the robot fleet.</span><strong><br /></strong></div> <div><br /></div> <div>&quot;If a human does something unexpected, such as suddenly going to the side, the traffic monitoring system must immediately detect this and ensure that the transport robot that is next to it acts so that an accident is avoided”, says Knut Åkesson.</div> <div><br /></div> <div><strong>Machine learning</strong></div> <div>What makes a traffic monitoring system like this possible today is the rapid development of computers' ability to interpret images in recent years. This is done with the help of machine learning and so-called artificial neural networks – that is, self-learning algorithms that are gradually trained to cope with their tasks. A bit like the way the human brain works.</div> <div><br /></div> <div>&quot;We are also trying to teach the system to predict how people will move in the next few seconds. This means that we can optimize in real time how the robot trucks should move in each unique situation that arises, all based on the information from the cameras&quot;, says Knut Åkesson.</div> <div><br /></div> <div><strong>Improved working environment and sustainability</strong></div> <div>But how will it feel to be in a work environment where humans and robots work so closely together, and is the fact that Volvo uses cameras something that could become a problem?</div> <div><br /></div> <div>&quot;Since the images and videos generated by the cameras will only be analysed by computers and not at all seen by a human eye, we see the cameras more as &quot;optical sensors&quot; rather than cameras, but of course, basically they are digital cameras we use”, says Per-Lage Götvall.</div> <div><br /></div> <div>&quot;In the discussions we have had with union representatives at Volvo, everyone has been positive that Volvo is driving the development. In the project, we are also happy that the relevant personnel categories can be involved in the design of GPSS, and those who are involved are all very positive about what we are doing”, Per-Lage Götvall continues.</div> <div><br /></div> <div>Knut adds that the ultimate purpose of &quot;giving eyes to the factory&quot; is to be able to control it better and thus also to make it cooperate better between the people and robots who work there.</div> <div><br /></div> <div>&quot;One could see it as a matter of improved working environment and thus also as a question of sustainability”, says Knut Åkesson.</div> <div><br /></div> <div>&quot;Optimisation of logistics is also important from a sustainability perspective. The aim is to consume as few resources as possible. For example, the transport robots must drive the shortest possible route and thus minimise energy consumption” Knut Åkesson continues.</div> <div><br /></div> <div><strong>Test environment</strong></div> <strong> </strong><div>Much of the algorithm development that the researchers work with takes place in a part of Volvo Trucks' factory in Tuve on Hisingen called the Pilot plant - a kind of experimental factory in the factory where new products and manufacturing methods are tested and developed.</div> <div><br /></div> <div>There, the researchers can test that the transport robots really behave in the way that the increasingly refined algorithms aim for in a realistic environment.</div> <div><br /></div> <div>Knut Åkesson believes that it will take a few years before Volvo Trucks is ready to introduce the new logistics system into production.</div> <div><br /></div> <div>&quot;The idea is that it should be able to be introduced in small steps. First in the pilot plant, then in a smaller part of the factory and finally in the entire truck factory”, says Knut Åkesson.</div> <div><br /></div> <div>Per-Lage Götvall adds:</div> <div><br /></div> <div>&quot;Since it is a completely new technology and a new way of &quot;socialising&quot; with autonomous robots, the &quot;precautionary principle&quot; requires that we take small steps and continuously evaluate what is happening. As part of this, we have industrial doctoral student Atieh Hanna. Her area of research is to see how we can develop safe but efficient systems and methods for workgroups where autonomous robots are included as a natural part&quot;.</div> <div><br /></div> <div><strong>About the collaboration</strong></div> <strong> </strong><div>The collaboration between Chalmers and Volvo Trucks has been going on during various project phases since autumn 2019 and has involved a handful of senior researchers, three doctoral students and a large number of students at master’s and bachelor's level. <span style="background-color:initial">For Chalmers, the current project period runs until summer 2023, but a continuation cannot be ruled out.</span></div> <div><br /></div> <div><strong>Facts</strong></div> <div><ul><li>The collaboration between Chalmers and Volvo AB regarding the truck factory of the future is part of the long-term partnership that was renewed for another three years at the latest in February 2022.</li> <li>The project now continues at Chalmers under the name AIMCor (AI-enhanced Mobile Manipulation Robot for Core Industrial Applications).</li> <li>Initiator and main manager at Volvo Trucks is Per-Lage Götvall, Senior Research Leader at the company.</li> <li>Researchers and engineers at Volvo who are involved in the development of GPSS are Associate Professor Kristoffer Bengtsson, Adamya Shukla, industrial doctoral students Erik Brorsson and Atieh Hanna.</li> <li>Chalmers researchers who are or have been involved include, in addition to Knut Åkesson, Yiannis Karayiannidis and Emmanuel Dean, as well as the three doctoral students Sabino Francesco Roselli, Ze Zhang, Endre Eres and Martin Dahl, who recently publicly defended his doctoral thesis.</li></ul></div> <div><br /></div> <span style="background-color:initial"></span><div><br /></div> <div><span style="background-color:initial">Written by: Sandra Tavakoli</span><br /></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><strong>For more information, contact:</strong></span></div> <div><strong>Knut Åkesson</strong>, Professor <span style="background-color:initial">of Automation at the Department of Electrical Engineering, Chalmers</span><span style="background-color:initial"> </span><span style="background-color:initial">University of Technology</span></div> <div><span style="background-color:initial">​</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><strong>Per-Lage Götvall</strong>, </span><span style="background-color:initial">Senior Research Leader, Volvo Trucks</span></div> <div><span style="background-color:initial"><br /></span></div>Mon, 28 Nov 2022 09:00:00 +0100 bicycle makes traffic safer for cyclists<p><b>​A self-driving bicycle, developed by students and researchers at Chalmers, can make the traffic environment safer for future cyclists.</b></p>​<span style="background-color:initial">No, it's not about us letting go of the handlebars to be able to spend the bike ride reading a book or studying bird life. The purpose of the autonomous bike is to make the future vehicle more intelligent.</span><div><br /><span style="background-color:initial"></span><div><strong>Vehicles shall discover cyclists</strong></div> <div>It will help the automotive industry engineers develop new systems that allow vehicles to automatically detect cyclists and predict their behaviour. And in the long run, to react completely on its own - for example, emergency braking. All to reduce the risk of traffic accidents between a vehicle and a bicycle.</div> <div><br /></div> <div>The background is that new vehicles are often equipped with one or more cameras, and radars, which can help the driver to keep track of what is happening in the traffic environment around the vehicle.</div> <div><br /></div> <div><img src="/en/departments/e2/news/Documents/Jonas_Sjöberg.jpg" alt="Jonas_Sjöberg.jpg" class="chalmersPosition-FloatRight" style="margin:5px;width:150px;height:196px" />Jonas Sjöberg, Professor of Mechatronics at the Department of Electrical Engineering at Chalmers, who leads the work of developing the self-driving bike, says:</div> <div><br /></div> <div>&quot;As a rule, such systems are first launched in premium cars, but after a few years the technology matures and becomes more of standard functions. This is often followed by government requirements for the function to be on board.”</div> <div> </div> <div><strong>Dummy used for tests</strong></div> <strong> </strong><div>But to require a function, it must be possible to test it. Compared to testing safety features between vehicles, an additional aspect must be considered when unprotected road-users are involved, such as pedestrians and cyclists. It is not acceptable with tests which are potentially dangerous for a test person, and that’s why a robot bike with a dummy will be used in the tests. </div> <div><br /></div> <div>&quot;An automatic system in the vehicle may, for example, need to consider if the cyclist staggers in connection with an overtaking, because the wobbling may increase the risk of an accident. The overtaking then needs to be done with a larger margin. But to test the function, it must be possible to repeat the wobble in the exact same way, time after time,” says Jonas Sjöberg.</div> <div><br /></div> <div>A human test cyclist can hardly do this. But a robot bike can be programmed to move identically as many times as you like. Swaying, starting a left turn or driving straight into the roadway - any threatening traffic situation that the vehicle should automatically be able to detect and react to.</div> <div><br /></div> <div>&quot;What is available today in the form of test equipment is a bicycle that is pulled on a small sled. This works for simpler tests. But with a robot bike, the manoeuvres could be much more realistic,” says Jonas Sjöberg.</div> <div><br /></div> <div><strong>&quot;Generation 2”</strong></div> <strong> </strong><div>There are currently two self-driving bicycles in use within the ongoing research project. According to Jonas Sjöberg, one could say that they belong to &quot;generation 2&quot;, even if the development does not follow any strict generational exchanges. It is rather about gradual improvements of the subsystems.</div> <div><br /></div> <div><strong>Areas of use</strong></div> <div>&quot;One of the ultimate goals of the project is that AstaZero will be able to offer a robot bike for those vehicle manufacturers who want to use a programmable bike in test situations,” Jonas Sjöberg says.</div> <div><br /></div> <div>But the self-driving bike also has other possible uses, for example actual crash tests, i.e., a vehicle drives on the bike and then you investigate how it went for the test doll that acted as a cyclist.</div> <div><br /></div> <div>&quot;It is a type of test that you cannot do with human test cyclists. But, for example, companies such as Autoliv are interested in developing protection for such situations,” Jonas Sjöberg says.</div> <div><br /></div> <div>From a sustainability perspective, the research could have a positive impact if a safer traffic environment for cyclists leads to more people daring to cycle in traffic instead of driving, according to Jonas Sjöberg.</div> <div><br /></div> <div><strong>Student project</strong></div> <div>The work with the robot bike has already been going on for a couple of years and a few more years remain before a fully usable prototype is ready. The development is mostly in the form of smaller student projects, where they improve the included subsystems.</div> <div><img src="/en/departments/e2/news/Documents/robotcykel%20masterstudenter.jpg" alt="robotcykel masterstudenter.jpg" style="margin:10px 5px;width:675px;height:465px" /><br />Master stundents working with the robot bike.  Photo: Chalmers<br /><br /></div> <div>It is mainly master's students from Systems, Control and Mechatronics and engineering students from the Mechatronics program at Lindholmen who participate. Students from Mälardalen University in Västerås are also involved, mainly when it comes to the construction of the electronic.</div> <div><br /></div> <div>In addition, a doctoral student is connected to the bicycle project. In his dissertation, Yixiao Wang develops the control algorithm, the mathematical instructions that are responsible for controlling the cycle and regulating speed. This is done based on sensor values that provide information a hundred times per second of the speed, direction, position, and inclination of the two-wheeler. A visiting doctoral student, Guanzheng Wen, from a university in China, is also currently participating in the work.</div> <div><br /></div> <div><strong>Vehicle testing</strong></div> <strong> </strong><div>Many of the practical tests take place in Chalmers' large car park on Johanneberg campus, but sometimes there is an excursion to the test track AstaZero, outside Borås, to perform active safety for more realistic vehicle testing.</div> <div><br /></div> <div>Whether the trend towards an increase of autonomous vehicles is good or bad for the environment and climate is a more open question.</div> <div></div> <div><br /></div> <div><strong>Facts:</strong></div> <div><div><ul><li><span style="background-color:initial">The self-driving bike is driven by an electric motor on the front wheel hub, and it also has a small electric motor on top of the front fork that handles the steering.

In Hungary, it was the first time that Chalmers Formula Student competed with a driverless electric car and we still came in seventh place with 24 teams competing. So, one could say that we won the rookie league, which feels great,&quot; says Linnéus Karlsson from the Chalmers team that took part in two rounds of the world's largest engineering competition for students, Formula Student, this summer. </b></p>​<span style="background-color:initial">This year marks the 20th anniversary of Chalmers' participation in Formula Student, the world's largest engineering competition for students. Ever since 2002, students from Chalmers' Formula Student course have designed and built their own Formula cars to compete against teams from technical universities from all over the world. In the 2015 round, the combustion engines were replaced by electric motors and since 2017 a new competition class was introduced as it was due time for self-driving electric cars to enter the racetrack. <br /><br /></span><div><strong>During the summer it was time for the 2022 </strong>edition of the competitions to take place. First in Austria and a couple of weeks later in Hungary. And for the first time, the Chalmers team was able to roll out a customized electric car adapted for both manual and autonomous control to the starting grid. A result that has been prompted by a multi-year and fruitful cross-department collaboration. <br /><br /><span style="background-color:initial">“The fact that we were now going to make the car autonomous required additional skills in the team. Ever since electric cars were introduced in the competition, this project has taken place in collaboration between departments and this year we were able to bring in more to work with electronics and software. Which went very well,” says Björn Pålsson, Associate Professor of Dynamics at the Department of Mechanics and Maritime Sciences and course leader of the Formula Student course.</span><br /></div> <div><h2 class="chalmersElement-H2">“You work right to the wire&quot;</h2></div> <div>This year's Chalmers team included around 30 students, mostly Master's students from Mobility Engineering, who have worked hard since September last year to get a car ready to go on time. All stages must be completed within a few months: from pre-study, design work and building of the car and finally testing.<br /><br /><span style="background-color:initial">“It’s good engineering to start from previous designs and carry over some parts, but the majority of the parts of the car are improved and redone. According to the rules, the team must be able to demonstrate &quot;significant changes to the chassis structure&quot; for the entry to qualify. If the judges notice that the car is too similar to previous entries, they’ll be disqualified,” explains Björn.</span><br /></div> <div><br /></div> <div><strong>This year, the team also needed time to</strong> develop an autonomous part that was ready to be fitted for the self-driving race in Hungary but removed for the driver-controlled races in Austria. And the process has no doubt been paved with a considerable amount of stress.<br /><br /></div> <div>“You work right to the wire. Time is short. It’s a big task in itself to build a car and typically the ambition level is too high for the vehicle concept. The only thing we have been tampering with is the amount of test time. But the team has managed to realize their concept and their idea and I think they should be very pleased with that,” says Björn.<br /><br /></div> <div><div><strong>During the competitions, the cars are scored</strong> in static events that assess the design and financial aspects of the car, and dynamic events that include: acceleration, which means that the car should cover a distance in shortest possible time starting from standstill, a so-called &quot;skid pad&quot;, which means that the car drives in a classic figure eight-shaped track, and driving on tracks of various lengths. In the driverless race, competitors use a remote control equipped with only a start button and an emergency stop. Apart from that, the car needs to be able to get around the track autonomously.<br /><br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/formula%20student%20lag%201%20750x340.jpg" alt="" style="margin:5px 10px;width:665px;height:306px" /><br /><br /></div> <h2 class="chalmersElement-H2">​&quot;One could say that we won the rookie league&quot;</h2> <div>So how did it go?</div> <div> </div></div> <div><strong>“In Austria, we came in tenth place in total</strong>. In Hungary, it was the first year that our team competed with a driverless electric car and we still came in seventh place with 24 teams competing. So, one could say that we won the &quot;rookie league&quot;, which feels great. And it probably beats our achievements in Austria. The other teams had been competing with driverless cars for a few years and the fact that we were able to succeed this well on the first go feels great. But we’re very pleased with our achievements in both Austria and Hungary,&quot; says Linnéus Karlsson, one of the members of the Chalmers team and master student in technical physics. <br /><br /></div> <div>“And of the 24 teams in Hungary, only four teams in total managed to get their car around the ten laps of the track drive course. And we were one of those four teams. Which we consider a success,” says Jakob Gunnarsson, also part of the Chalmers team that competed in this year's edition.<br /><a href="">Here you can watch a film from the driver controlled race in Austria</a> and <a href="">here you can watch one from the driverless races in Hungary! <br />​</a><br /></div> <div><strong>The Chalmers team performed best</strong> of the Nordic countries, and although their achievements are considered a success, it was – just like in previous years – the Germans who dominated on the winners’ stand. In the Austrian competition, it was the German team from Stuttgart that won the gold and in the driverless races in Hungary, the German team from Karlsruhe came in first place. <br /><br /></div> <div><div>“The German teams are very competitive, and they test more and have a lighter car. Our team at Chalmers can no doubt build a &quot;state-of-the-art&quot; car, but the best German teams are better at building a lighter car. And they also have great drivers,&quot; explains Björn. </div> <h2 class="chalmersElement-H2">Sharing of knowledge and arch-rivals</h2></div> <div>And despite the fact that the presentations that the teams give to the judges are closed to competitors, the sharing of knowledge is generous between the teams during the events. Which the Chalmers team tries to make the most out of ahead of upcoming competitions.<br /><br /></div> <div>“We’re looking at all the teams, but above all the German ones, in order to find out what is state of the art in this area. Most teams are open about their designs, and you can definitely learn from each other. And we’re developing our own power electronics within the framework of the course. So, we hope the car will be lighter next year. Currently, our car weighs a bit more than 200 kilos in the manual configuration. The best German cars only weigh about 170 kilos, says Björn.<br /><br /></div> <div><strong>The German teams may be a leading</strong> country in the field, but it’s a completely different competitor that the Chalmers team and - perhaps above all - their course leader Björn are trying to beat. <br /><br /></div> <div><div>“I’ve made NTNU in Trondheim our arch-rivals, just because it’s fun to have one and because they’re Norwegian. And this year they actually performed worse than Chalmers, even though they are normally very good. So, it's great if we can beat them once in a while. When NTNU's car broke down in 2018, the commentators said that the entire Chalmers team probably would be getting a round of beer for beating NTNU” says Björn, laughing.</div> <h2 class="chalmersElement-H2">&quot;You get to do something for real&quot; </h2></div> <div>Today, a couple of weeks after the 2022 Formula Student has been concluded, the team members are confident that the lessons learnt from the experience will bring benefits, not only in the preparations for next year’s round, but perhaps even more so for future studies as well as professional career. <br /><br /></div> <div><strong>“The best thing about this course</strong> is probably that you get to work both theoretically as well as practically. I come from Engineering Physics which is primarily theoretical. Here you really get the chance to participate and do something for real,” says Formula Student member Linnéus.</div> <div><br /></div> <div>And fellow student Jakob agrees:</div> <div>“Even in industry, you will never get the chance to get as involved in all stages of the chain. But here, you really do, from start to finish.”<br /><br /></div> <div>“A Formula student team basically faces the same challenges as a real vehicle manufacturer, but on a smaller and simplified scale.

This is Chalmers' contribution to a future method that will make it possible to safely test drive vehicles, even without a driver on board.</b></p>​<span style="background-color:initial">Those who have chosen a test driver profession not only need to have a high tolerance threshold for long and uncomfortable work shifts behind the wheel. It is as important to have the ability to detect early signs that a significant part of the vehicle is becoming malfunctioning.</span><div><br /><span style="background-color:initial"></span><div>But how can this safety-critical professionalism be passed on to a future when more and more vehicles become self-driving? Is it possible to mix self-driving and driver-controlled vehicles on one and the same test track? How is safety affected when there is no longer anyone on board who can break or steer to the side to prevent an accident? These are some of the issues behind ETAVEP (Enablers for testing autonomous vehicles at existing testing grounds), a research project co-financed by Vinnova program Vehicle Strategic Research and Innovation, which takes a closer look at the challenges in vehicle testing that arise as cars become increasingly autonomous.</div> <div><br /></div> <div>Researchers from Chalmers, together with the truck manufacturer AB Volvo and the car manufacturer Volvo Cars, have focused on the part of the project that deals with the fact that vehicles must be able to be monitored even when a person's ears, sensory organs and experience are not in place. </div> <div><br /></div> <div>The task has thus been to create an automated system that in real time can give an indication that some mechanical component that is important for safety is about to fail.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/ETAVEP/Tomas_McKelvey-1.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Tomas McKelvey, Professor in Signal processing at the Department of Electrical Engineering and, who has led the research within the subproject, explains:</div> <div><br /></div> <div>&quot;The problem lies in how to best monitor a vehicle when you do not know in advance what it is that will break.”</div> <div><br /></div> <div>He emphasises that one cannot rely on the systems that need to be on board once the self-driving vehicles come out in normal traffic - this is because test drives can take place even in earlier phases of vehicle development before the autonomous functions are reliable.</div> <div><br /></div> <div>You could say that the approach chosen is somewhat reminiscent of how the human perception works - we are usually quite good at paying attention to sensory impressions that deviate from what is expected. </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/ETAVEP/Picture-11_340x305.jpg" class="chalmersPosition-FloatLeft" alt="" style="background-color:initial;margin:5px" />A few dozen accelerometers, placed in strategically important places in the vehicle, have been allowed to act as the system's tactile rod. They register how the vibrations that occur in the engine and in contact with the road surface propagate further out into the body and components.</div> <div><br /></div> <div>“Our hypothesis has been that the nature of the vibrations will change when an error occurs on board and that the changes can be registered with the help of these instruments.” </div> <div><br /></div> <div>To prevent a changed road surface from triggering a &quot;false alarm&quot;, some of the sensors, located near the vehicle's wheels, are used to register the input signal. The rest of the instruments should then be able to pick up such changes that are due to faults on board.</div> <div><br /></div> <div>But to know how a broken car vibrates, an automatic system must first learn how a faultless car behaves. So, the collection of this data became the researchers' first task once the instrumentation of the two test vehicles - a heavy truck and a passenger car - was completed. </div> <div><br /></div> <div>&quot;We achieve this by creating a so-called transfer function, a mathematical description of how different parts of the car move together.”</div> <div><br /></div> <div>He adds that this type of analysis creates &quot;an awful lot of data&quot; - it is about 1,500 so-called complex numbers (numbers that have a real part and an imaginary part) per second. </div> <div><br /></div> <div>&quot;From these data, we build a stochastic model that describes the normal case, where each value is allowed to have a certain variation.”</div> <div><br /></div> <div>In the next stage, the researchers let the two test cars roll on the same surface as before, but now with various intentional errors introduced in the vehicles. </div> <div><br /></div> <div>Data from the accelerometers were analysed again - this time with the hope that the monitoring system could perceive changes in vibrations as an indication of the faults. </div> <div><br /></div> <div>Did it work? </div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/ETAVEP/Picture-4_750x340px.jpg" alt="" style="margin:5px;width:685px;height:314px" /><br /><br /><span style="background-color:initial">&quot;Yes,</span><span style="background-color:initial"> the system could quite easily detect errors - even such errors that according to the test drivers are very difficult to detect.”</span><br /></div> <div><br /></div> <div>&quot;Only one of the intentional faults did the system bite on - a nut on a shock absorber attachment that had been loosened a few turns on the heavy truck. But on the other hand, it was a fault that the test drivers could not feel either.”</div> <div><br /></div> <div>The automatic monitoring system that the Chalmers researchers have developed reacts to something being wrong - but the system cannot tell exactly where the fault is. </div> <div><br /></div> <div>&quot;You could probably work on this fur<span style="white-space:pre"> </span>ther, but we have not had time for that in this study. From a safety point of view, the most important thing is to find out that an error has occurred, so that the vehicle can be taken off the test track.”</div> <div><br /></div> <div>The practical experiments with the monitoring system took place last autumn at Volvo's test track in Hällered outside Borås, where the test facility AstaZero, run by Chalmers and RISE, is also located.</div> <div><br /></div> <div>In addition to monitoring vehicle status, which the Chalmers researchers worked on in this sub-project, ETAVEP also includes methods and systems for traffic monitoring and vehicle control, including using radar, light radar (lidar) and camera surveillance. The systems are linked to communication based on 5G technology. </div> <div>According to Tomas McKelvey, the methodology developed within the overall ETAVEP project is the first among test facilities around the world, when it comes to allowing autonomous and driver-controlled vehicles to coexist. </div> <div><br /></div> <div>&quot;The hope is that the methods developed will become a kind of international standard for test tracks.” </div> <div><br /></div> <div>He adds that representatives of other test facilities have shown great interest in the project. The reason is that there are both economic and environmental benefits from being able to use existing facilities, rather than having to sacrifice land and resources to build new test tracks only for autonomous vehicles. </div> <div><br /></div> <div>&quot;In addition, the test driver's working life as it looks today is very physically stressful. So even from that aspect there is a sustainability perspective,” Tomas McKelvey concludes.</div> <div><br /></div> <div><br /></div> <div>Written by: Sandra Tavakoli</div> <div><br /></div> <div><br /></div> <div><strong>Facts about the research: </strong></div> <div><ul><li>The two-year research project ETAVEP (Enablers for testing autonomous vehicles at existing testing grounds) is part of the Vinnova program Vehicle Strategic Research and Innovation. </li> <li>In addition to AB Volvo and Volvo Cars and Chalmers, the project participants consist of the research institute RISE, the test facility AstaZero and the research company SafeRadar. </li> <li>Final report from the project will be written in the spring. </li> <li>In addition to Tomas McKelvey, those who worked on the sub-project on automatic monitoring have been Project Manager Patrik Nordberg from Volvo Cars and Daniel McKelvey, a student in Engineering mathematics and computational science at Chalmers, who had the project as his master thesis. </li></ul></div> <div><br /></div> <div><strong>Facts / Accelerometer</strong></div> <div>An instrument that measures acceleration in relation to free fall, often in three dimensions, and which is found in every modern mobile phone, among other things.

Researchers at Chalmers University of Technology, Sweden, have developed a new form of AI, which, by observing human behavior, can adapt to perform its tasks in a changeable environment. The hope is that robots which can be flexible in this way will be able to work alongside humans to a much greater degree.​</b></p><div>“Robots that work in human environments need to be adaptable to the fact that humans are unique, and that we might all solve the same task in a different way. An important area in robot development, therefore, is to teach robots how to work alongside humans in dynamic environments,” says Maximilian Diehl, Doctoral Student at the Department of Electrical Engineering at Chalmers University of Technology and main researcher behind the project.</div> <div><br /></div> <div>When humans carry out a simple task, such as setting a table, we might approach the challenge in several different ways, depending on the conditions. If a chair unexpectedly stands in the way, we could choose to move it or walk around it. We alternate between using our right and left hands, we take pauses, and perform any number of unplanned actions.</div> <div><br /></div> <div>But robots do not work in the same way. They need precise programming and instructions all the way to the goal. This approach makes them very efficient in environments where they constantly follow the same pattern, such as factory processing lines. But to successfully interact with people in areas such as healthcare or customer facing roles, robots need to develop much more flexible ways of working.</div> <div><br /></div> <div>“In the future we foresee robots accomplish some basic household activities, such as setting and cleaning a table, placing kitchen utensils in the sink, or help organizing groceries,” says Karinne Ramirez-Amaro, Assistant Professor at the Department of Electrical Engineering.</div> <div><br /></div> <div>The Chalmers University researchers wanted to investigate whether it was possible to teach a robot more humanlike ways to approach solving tasks – to develop an ‘explainable AI’ that extracts general instead of specific information during a demonstration, so that it can then plan a flexible and adaptable path towards a long-term goal. Explainable AI (XAI) is a term that refers to a type of artificial intelligence where humans can understand how it arrived at a specific decision or result.</div> <div><br /></div> <div style="font-size:16px"><strong>Teaching a robot to stack objects under changing conditions</strong></div> <div><br /></div> <div>The researchers asked several people to perform the same task – stacking piles of small cubes – twelve times, in a VR environment. Each time the task was performed in a different way, and the movements the humans made were tracked through a set of laser sensors.</div> <div><br /></div> <div>“When we humans have a task, we divide it into a chain of smaller sub-goals along the way, and every action we perform is aimed at fulfilling an intermediate goal. Instead of teaching the robot an exact imitation of human behavior, we focused on identifying what the goals were, looking at all the actions that the people in the study performed,” says Karinne Ramirez-Amaro.</div> <div><br /></div> <div>The researchers' unique method meant the AI focused on extracting the intent of the sub-goals and built libraries consisting of different actions for each one. Then, the AI created a planning tool which could be used by a TIAGo robot – a mobile service robot designed to work in indoor environments. With the help of the tool, the robot was able to automatically generate a plan for a given task of stacking cubes on top of one another, even when the surrounding conditions were changed. </div> <div><br /></div> <div>In short: The robot was given the task of stacking the cubes and then, depending on the circumstances, which changed slightly for each attempt, chose for itself a combination of several possible actions to form a sequence that would lead to completion of the task. The results were extremely successful.</div> <div><br /></div> <div>&quot;With our AI, the robot made plans with a 92% success rate after just a single human demonstration. When the information from all twelve demonstrations was used, the success rate reached up to 100%,&quot; says Maximilian Diehl.</div> <div><br /></div> <div>The work was presented at the robot conference IROS 2021, one of the world’s most prestigious conferences in robotics. In the next phase of the project, the researchers will investigate how robots can communicate to humans and explain what went wrong, and why, if they fail a task.</div> <div><br /></div> <div style="font-size:16px"><strong>Industry and healthcare</strong></div> <div><br /></div> <div>The long-term goal is to use robots in the industry to help technicians with task that could cause long-term health problems, for example tightening bolts/nuts on truck wheels. In healthcare, it could be tasks like bringing and collecting medicine or food. </div> <div><br /></div> <div>“We want to make the job of healthcare professionals easier so that they can focus on tasks which need more attention,” says Karinne-Ramirez Amaro.  </div> <div><br /></div> <div>&quot;It might still take several years until we see genuinely autonomous and multi-purpose robots, mainly because many individual challenges still need to be addressed, like computer vision, control, and safe interaction with humans. However, we believe that our approach will contribute to speeding up the learning process of robots, allowing the robot to connect all of these aspects and apply them in new situations”, says Maximilian Diehl.</div> <div><br /></div> <div>By: Sandra Tavakoli and Karin Wik</div> <div><br /></div> <div><div>The research was carried out in collaboration with with Chris Paxton, a research scientist at NVIDIA.
