<；P>；PROBLEM TO BE SOLVED: To provide an all-fingers movable type artificial hand which can also be converted into a robot hand, with palm shape and light weight, and good design, which enables five fingers to be operated independently, enables flexure in the joint part, extension and throwing power, wrist exercises to the palm and the back, inward and outward rotation movement, and makes gripping sensibled in the sensory area of the brain. <；P>；SOLUTION: The artificial hand is composed of engineer plastic or aluminum or other materials for light weight and designed to have human palm shape. Independent operation of five fingers and improvement of gripping power are realized by using the interference driving method, and gripping of the artificial hand and sensibility for gripping with visual and touching sensation through sensation feedback system are enabled. The hand includes a sensor for sensing rotation and bending. By these mechanisms, the all-finger movable type artificial hand can be converted into a robot hand. <；P>；COPYRIGHT: (C)2008,JPO&INPIT
