Abstract

The system and the method are intended to enable a robot (20) to see the environment in which it operates, by means of a pair of identical cameras (3). The pictures from the cameras (3) are processed by a coordinator/translator (59). The system includes a memory register (51) for movement identification at time intervals.A basic shapes registry (52) identifies shapes.
