Abstract: The present disclosure relates to a robot, and provides a 3 degree-of-freedom parallel mechanism with 3 branched-chains, which includes a fixed platform, a movable platform, and three arc-shaped connecting rods. The rotation axes of three arc-shaped connecting rods are intersected with each other and each rotation axes is parallel to the fixed platform. Each arc-shaped connecting rod has a sliding slot curved extending along a longitudinal direction. The three connecting shafts one-to-one corresponds to the three arc-shaped connecting rods and are disposed on the movable platform. A first end of each connecting shaft is fixedly connected with the movable platform. A second end is hinged joint with a connecting head. The connecting head is slid and disposed in the corresponding sliding slot.
