Actuator

摘要

The invention relates to an actuator and to its application to the position servocontrol for a master-slave remote manipulator. The actuator comprises a box or case in which are housed an electric motor, a slightly or non-reversible reducing gear and a torsion bar connecting the led part of the gear to an actuating plate outside the box. Potentiometers make it possible to define the position of the led part with respect to the box and the force applied to the torsion bar. Thus, it is possible to artificially provide the gear with good reversibility characteristics. Application to any movement control in robotics and particularly to the production of miniaturized master arms, master-slave remote manipulators with force return and without either a cable or belt, and to the control of heavy arms.
