Robotic vehicle designed for independent operation

摘要

The vehicle (1) has drive units (6) for steering and moving the vehicle on an subsurface, and a control unit (7) for controlling the drive units depending on signals of two sensor units (8a, 8b). One of the sensor unit is formed and arranged for receiving frequency signals, which is reflected from the subsurface that resides below the vehicle. The another sensor unit receives another frequency signal, which is reflected by the subsurface that resides outside of the vehicle external contour (10).
