ABSTRACT:
A robot for guiding movements has its power provided by an operator who handles a tool integral with the robot. Like a conventional robot, the guiding robot has several axes respectively associated with rotation sensors that are connected to a computer system memorizing a path to be followed. When the operator moves the tool beyond the stored path, blocking devices, controlled by the computer system and replacing the robot's motors, prevent the tool from continuing to depart from the path. Thus, at any time, the operator can move the tool within the stored path only. The blocking devices are passive, that is, they are such that they can only resist to a movement but cannot generate a movement, which prevents the occurrence of any uncontrolled movement.
