[0022] Such as Figure 1~7 As shown, a dexterous hand driven by a shape memory alloy includes a first finger 1, a second finger 2, a third finger 3, a palm 4, and a control system. The first finger 1, the second finger 2, and the third finger The fingers 3 have the same structure. The palm 4 is provided with a first finger 1, a second finger 2, and a third finger 3. The fingers include a distal phalanx 5, a middle phalanx 6 and a proximal finger connected in sequence Joint bone 7, each finger has 3 degrees of freedom, the distal interphalangeal joint 10 realizes the flexion and extension movement of the distal phalanx, the proximal interphalangeal joint 9 realizes the lateral movement of the finger, and the metacarpophalangeal joint 8 realizes the flexion and extension of the entire finger Movement, the distal phalanx 5 includes a fingertip 21, an M1.6X4 screw 22, and a first connecting piece 23. The fingertip 21 is connected to the first connecting piece 23 via an M1.6X4 screw...
