Telescopic system for a robot

摘要

A telescopic system for a robot includes a frame for mounting a motor, a stationary module mounted on the frame and a rotational shaft rotating by the motor. The rotational shaft is mounted in the stationary module, and a movable plate is associated with the rotational shaft to ascend and descend according to a rotational motion of the rotational shaft. A movable module is mounted on the movable plate to expand away from and retract into the stationary module as the movable plate ascends and descends.
