Abstract
A control system for robots comprising a control unit for generating and controlling the paths of a movement of the moving parts of the robot, a drive unit for generating the control signals for controlling the motors associated to the moving parts of the robot, and an Ethernet-type network for connection of the control unit and the drive unit. An interface module is also provided to connect the control unit to peripheral units and distributed input/output units. The drive unit comprises, in conjunction with a plurality of CPUs that close the control loops of the torques generated by the individual motors, a main CPU responsible for position control in the framework of the drive unit. The latter CPU thus retains knowledge of the overall status of the machine.
