Therefore in this paper we developed the hand which can grasp various objects and exert large gripping force To develop such hand, we focused on the thumb cm joint with wide range of motion and the mp joints of four fingers with the dof of abduction and adduction. Featuring five independent fingers with multiple dofs, this design enables precise and flexible movement. The use of thin (100 μm diameter) sma wire actuators, in conjunction with an entirely 3d printed hand skeleton, guarantees an overall lightweight and flexible structure capable of silent motion. five fingered hand. 是一种拇指发育不全的先天性拇指畸形。 按Blauth (1967年)的分类法,此类型的畸形为人第五度拇指发育不全。 拇指不在对掌位,大鱼际肌不发育,拇指指骨发育成三节指骨很似其他手指,故称五指手畸形。 治疗可将桡侧的第一指移位成对掌位,同时短缩使之拇指化。
