Dexterous hand thumb structure and dexterous hand
By employing a parallel design and Hooke's hinge connection in the thumb structure of the dexterous hand, and independently setting the metacarpal and phalangeal drive components, the problem of insufficient thumb movement flexibility in the prior art is solved, and efficient grasping and precise control of the dexterous hand are achieved.

AI Technical Summary
The existing dexterity hand thumb structure fails to fully consider the differences in skeletal anatomy between the thumb and the other four fingers in the human hand, resulting in insufficient motor flexibility, poor grasping effect, and complex kinematic calculations that are not conducive to precise control.
Design a dexterous thumb structure including a base, metacarpals, phalanges, and drive components. Through independent metacarpal drive components and phalange drive components set inside the metacarpals, multi-degree-of-freedom movement of the thumb's carpometacarpal joint, metacarpophalangeal joint, and interthorax joint is achieved. The parallel design and Hooke's hinge connection enhance the thumb's flexibility and gripping effect.
It enables flexible thumb movement, improves gripping performance, simplifies kinematic calculations, enhances the overall operational ability and flexibility of dexterous hands, reduces inertia, and minimizes shaking.
