In this experiment all visual obstacle detection facilities have been deactivated. The robot merely reacts on tactile impacts on the instrumented bumper system.
Besides the industrial safety bumper, RAVON's bumper bar is equipped with a deflexion measurement system, which allows the robot to analyse its environment in a tactile fashion. Tactile events are cast into a short-term memory which is resampled into abstract views. These views are used for obstacle avoidance as if the data was obtained by visual sensors. That way the robot can see touch just like a human would in complete darkness. The robot has to drop to creep velocity (10cm/s) to detect obstacles in a tactile fashion. Therefore, the video is played in 4x speed.
