Marine research platforms

Revere has entered the field of marine research. The lab continues to expand its activities to the growing interest of automation in the marine sector. Apart from the radar systems, the sensor technology used does not differ much between land and sea, thus Revere can transfer a lot of existing systems, knowledge, and experience into marine applications. Revere has engaged in establishing several marine research platforms, some of which are described below.

Pilot Boat ”Seastar” 

Seastar is a 13 meter long instrumented pilot boat used for autonomous navigation and data collection. The instrumentation include two arrays of cameras, one for computer vision applications, and one for remote operations, a high-accuracy three-antenna GNSS system, a marine radar, an array of lidar sensors, and a high-accuracy ground truth FOG-IMU. Importantly, the boat is used in the collection of data for the Reeds open dataset hosted at Chalmers. In addition, both engines and the water jet actuators are interfaced for the purpose of autonomous control.

Catamaran marine drone “Seacat”

Seacat is a 2.5 meter long instrumented catamaran marine drone used for autonomous unmanned missions and data collection. Above the waterline, it is equipped with an array of cameras, used for remote monitoring and control, and a lidar. Under water, the platform carries two high-resolution cameras for computer vision, as well as a multibeam sensor. The platform is differentially steered by using two individually controlled electric motors. It is also equipped with a rudder for maximum controllability. The platform was designed and built by SP Marine Tech, in close collaboration with Chalmers and RISE. 

RC Boat ”Porpoise”

Porpoise is a 1 meter long scale model of an autonomous boat. The model has a similar set up to a lot of modern merchant ships with independent rudders, propellers and a tunnel thruster. It is fitted with hardware and sensors to prepare it for collection of weather and ocean data and also for autonomous operation, with modularity and possible expansion of complexity in mind. To prepare it for independent navigation, there is both a simple buoy detection algorithm used with implemented cameras and a GPS interface.
