Abstract:
Disclosed herein is a weight compensation mechanism. A weight compensation mechanism is installed in a link member rotatable in a plurality of directions. The weight compensation mechanism includes a plurality of bevel gears that rotates in harmony with the rotation of the link member. Cam plates are connected to one or more of the bevel gears to be rotated together with the bevel gears. Weight offsetting parts are connected to the cam plates, respectively, and each of the weight offsetting parts compresses an elastic member based on the rotation of the link member and the cam plate to absorb gravitation generated by the weight of the link member.
