ABSTRACT:
A method and device are disclosed for controlling the movement of a machine on a surface. The device comprises an obstacle disposed along at least part of an area to be traversed by the machine, a winder-unwinder device connected to the machine, and an anchor which is located remote from the machine and which is stationary with respect to the surface. A flexible connection is attached at one end to the machine at another end to the anchor. An obstacle detector, carried by the machine, detects the presence of the obstacle. A device successively frees a given length of the connection when the obstacle is detected. A propulsive device causes the machine to travel in a direction in which the connection is stretched again after the length of the connection is freed, and then causes the machine to travel in a direction which is opposite to a direction in which the machine was travelling before the obstacle was detected.
