It has two main parts. A chassis with wheels powered by electric motors and a two-meter long pole, which is basically its brain - LiDAR and cameras that allow it to recognize objects in its surroundings. Then on that head is also what's called an HMI, a set of screens that signal both drivers and pedestrians. In addition, the rover can send a signal to an approaching car, for example to its infotainment system.
Simply put, it's a smart mobile traffic light. This so-called rover has been developed by two Italian startups, Hipert and Lifetouch, and Škoda Auto is also involved, having even developed a special mask for the Enyaq iV car that could give signals to pedestrians, and the Prague CTU has helped with communication between the rover and cars, or a special application. The entire project, funded by the European Union, is overseen by the Technical University of Munich.
