ABSTRACT:
A manipulator module comprises an arm bearingly mounted on an axle, confined between left and right adjustable stops with a suitably completed fixing surface. On the arm are stationary mounted hard stops with slits, charged with helical cylindric springs. The springs contact the adjustable stops when the arm approaches the respective stop. Onto parallel guideways, formed by the stationary stops with slits, roll the extreme bearings of a three bearing bearings block, the intermediate bearing of which contacts the fixing surface of the respective stop while the mover is at "on" position. When the arm has reached the stop and has deformed the spring, the "fix" mover is actuated, the arm is fixed to the stop and the energy lost during the arm's movement is added.
