Summary:The present invention relates to a robot hand. According to the present invention, the robot hand comprises: a plurality of metacarpal bones disposed at a palm portion to connect a plurality of fingers and a wrist, respectively; an inter-metacarpal (IMC) joint portion disposed between the metacarpal bones, and connecting the metacarpal bones to be rotated with respect to a shaft in parallel to each metacarpal bone; and a joint driving portion for providing a driving force for rotation of the IMC joint portion, thereby providing the robot hand capable of improving precision in gripping performance by enabling cupping of the robot hand. 본 발명은 로봇 핸드에 관한 것으로서, 본 발명에 따른 로봇 핸드는, 손바닥 부분에 배치되어 복수의 손가락과 손목을 각각 연결하는 복수의 손허리뼈(Metacarpal bone);와, 상기 복수의 손허리뼈 사이에 각각 배치되고, 상기 복수의 손허리뼈를 각각 손허리뼈와 나란한 축으로 회동 가능하게 연결하는 IMC(Inter-Metacarpal)관절부; 및 상기 IMC관절부의 회동을 위한 구동력을 제공하는 관절구동부;를 포함하는 것을 특징으로 한다. 이에 의하여, 손을 오므리는 동작을 가능하게 하여 정밀 파지 능력을 향상시킬 수 있는 로봇 핸드가 제공된다.
