| contents | The robotic dexterous hand is responsible for both grasping and dexterous manipulation. The number of motors directly influences both the dexterity and the cost of such systems. In this paper, we present MuxHand, a robotic hand that employs a time-division multiplexing motor (TDMM) mechanism. This system allows 9 cables to be independently controlled by just 4 motors, significantly reducing cost while maintaining high dexterity. To enhance stability and smoothness during grasping and manipulation tasks, we have integrated magnetic joints into the three 3D-printed fingers. These joints offer superior impact resistance and self-resetting capabilities. We conduct a series of experiments to evaluate the grasping and manipulation performance of MuxHand. The results demonstrate that the TDMM mechanism can precisely control each cable connected to the finger joints, enabling robust grasping and dexterous manipulation. Furthermore, the fingertip load capacity reached 1.0 kg, and the magnetic joints effectively absorbed impact and corrected misalignments without damage. |
