Abstract:
The present invention discloses a weight compensation mechanism installed at a rotatable three-degree-of-freedom link member, wherein a first rotation of the link member is a yaw rotation aligned with the direction of the gravity and second and third rotations of the link member are respectively a roll rotation and a pitch rotation, wherein the second and third rotations are restrained by a plurality of differential bevel gears, and wherein a pair of cam plates is fixed to shafts of a pair of rotary bevel gears in the plurality of differential bevel gears, and a one-degree-of-freedom weight compensator is provided to be connected to the cam plates.
