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.

Abstract: A three-degree-of-freedom parallel mechanism with curved sliding pairs includes a fixed platform, a moving platform, and three curved branches disposed between the fixed platform and the moving platform. Each of the curved branches includes a first curved link and a second curved link that share a common arc center. One end of the first curved link is connected to fixed platform by a rotational pair. One end of the second curved link is disposed in a cavity at another end of the first curved link. The second curved link is operative to perform a reciprocating motion along a tangent of an arc of the first curved link. Another end of the second curved link is connected to the moving platform by a ball joint. The axes of the three rotational pairs of the three curved branches coincide with each other and are perpendicular to the fixed platform. In the three-degree-of-freedom parallel mechanism with curved sliding pairs, the moving platform of the parallel mechanism is rotatable around the X-axis, Y-axis, and Z-axis of a three-dimensional coordinate system taking the arc center of the three curved branches as the origin, where the rotation of the moving platform about the Z axis is decoupled from the rotation in the other two orientations.

Abstract: A 2 DOFs decoupling parallel mechanism provided by the present disclosure comprises a fixed platform, a rotation assembly, a moving platform, an arc kinematic chain, and an arc rod. In the 2 DOFs decoupling parallel mechanism, the rotation assembly can drive the moving platform to rotate by 360 degrees around a direction being perpendicular to the fixed platform, the arc rod reciprocates along the tangential direction of the arc kinematic chain to enable the moving platform to rotate around an axis of a plane where the arc kinematic chain is located. In this way, the rotations of the moving platform in two directions are respectively driven by driving units in two directions and being independent from each other, such that the two rotation actions of the mechanism have decoupling capability.
