ACTUATOR FOR ROBOT AND HUMANOID ROBOT COMPRISING THEREOF

摘要

PURPOSE: An actuator for a robot and a humanoid robot including the same are provided to improve the efficiency of force reflection, since a ball nut portion moves linearly along a ball screw portion without distortion. CONSTITUTION: An actuator for a robot comprises a rotation driving source, a screw member(300), a guide member(700), a slider member(600), and a connecting member(500). The screw member comprises a screw portion(310) and a nut portion(320). The screw portion connects to the rotation driving source. The nut portion is combined with the ball screw portion. The guide member is parallel in the ball screw portion. The slider member is movably supported in the guide member. As the connecting member connects the slider member and the nut portion, the slider member engages with the nut portion.
