Abstract
Provided is a rotary actuator unit using simple link structure, and a robot joint unit employing the same. The rotary actuator unit comprises a first input part, a second input part, an output link member, an intermediate link member, an output side shaft OP, an intermediate shaft MP, and an input side shaft IP. The first input partand the second input partconstitute an input side link mechanism Lhaving two degrees of freedom. The intermediate link memberand the output link memberconstitute an output side link mechanism L. A tip of the input side link mechanism Land a base end of the output side link mechanism Lare rotatably supported around the input side shaft IP. A two dimensional position of the input side shaft IP is freely manipulated by controlling a first liner actuatorof the first input partand a second linear actuatorof the second input part. A rotation of the output link member around the output shaft OP is used as an output.
