Robotic hand device with thenar muscles

Abstract

The present invention is a robotic hand device with thenar muscles, comprising a finger unit, a palm unit, a thenar unit, a first drive unit, a second drive unit, and a processor unit. When the processor unit issues a gripping instruction, the processor unit drives the finger units and the palm unit through the first drive unit to bend towards a central area of the palm until the finger units and the palm unit grip the object, and the processor unit drives the thenar unit through the second drive unit to move towards the central area of the palm until the thenar unit leans against the object. In this way, the robot hand device with thenar muscles using lead screw mechanism can firmly grip the object through the thenar unit in a more stable manner to improve a dynamic holding stability and to reduce risks of dropping the object.
