ABSTRACT:
A device for guiding a civil engineering/earthmoving machine using laser beams having a laser emitter and two laser receivers each mounted on a displacement unit mobile with two degrees of freedom. Two receiver position sensors are associated with each unit to measure its position with reference to two degrees of freedom and to generate signals representative of this position. A machine position sensor measures the position of the machine with reference to a fifth degree of freedom and generates a signal representing this position. A computer responsive to these signals stores the geometrical features of the surface over which the machine is guided and controls each receiver in two dimensions to maintain it centered on the beam from the laser emitter. The computer also generates in real time command instructions applied to actuators controlling the machine, on the basis of these geometrical features.
