The growing number of applications in automated robots and vehicles has led to an increasing demand for positioning, location and tracking systems. The majority of methods currently in use are based on machine-vision systems, and require a direct line of sight between the tracking device and the target at all times, to carry out the desired functions. This limits the possible applications and makes them vulnerable to disturbances.
Gabriel Ortiz and Fredrik Treven have built a prototype for tracking devices, demonstrating an innovative variant of UWB positioning where a set of anchors follows the target's position, and maintains a specific distance to it. This is in contrast to common indoor positioning systems, where the target monitors its own position in relation to fixed reference points.
Examples of gadgets that could follow you around in the future are shopping carts, suitcases, as well as various kinds of toys.
