Robot tries to keep constant distance from the obstacle. If the obstacle is closer, robot walks backward and vice-versa.

Robot is controlled with RC transmiter. It has also activated ultrasound ranger for notification when near obstacle appears.

This robot doesn't require any program or neural network and still looks like inteligent robot. For obstacle avoidance it uses very simple circuit....
