Task 

The sensors in the bumpers are transmitters and receivers for the ultrasonic signals necessary for measuring the distance to an obstacle.

Function 

When actuated by the PTS control unit (N62), the sensors emit an ultrasonic signal. After a short decay time the sensors are ready to receive. Each sensor receives the echo of its own signal and that of the other sensors. The distance to the obstacle is calculated from the elapsed time between transmission and reception.
