Abstract
A robot joint driving apparatus and a robot having the same are capable of minimizing a load applied to a drive motor by rotating a ball nut part such that a ball screw part performs linear movement in a power transmission structure using a wire and the ball screw apparatus. The robot joint driving apparatus includes a reversible drive motor, a ball nut part rotated according to operation of the drive motor, a ball screw part performing linear movement according to rotation of the ball nut part, a wire connected to the ball screw part from both sides of the ball screw part, an idle pulley rotatably installed at one side of the wire, and a joint part rotatably installed at an opposite side of the wire.
