Method for fine-positioning articulated systems by the association of actuators of different powers

摘要

This method allows, by associating an imprecise low-range power actuator 5 with an actuator 3 of low power in comparison with the first, the play of the power actuator to be taken up to ensure good quality positioning 1 by acting on one and the same articulation 2. The method according to the invention can be applied to mechanical systems where good precision in the positioning of a spindle is required (manipulation arm, industrial robot spindle). <IMAGE>
