Abstract
The present invention allows a joint driving apparatus of a robot apparatus to measure joint driving torque with high accuracy and perform joint torque control accurately and reliably using a simple, inexpensive, small, lightweight and sturdy configuration without being affected by cross-axis disturbance forces. A joint driving apparatus includes a housing unit fixed to a first link; a bearing mounted in the housing unit and adapted to rotatably support a second link; a driving unit housed in the housing unit and adapted to rotationally drive the second link; a supporting unit installed between the driving unit and the housing unit and adapted to support the driving unit on the housing unit; and a sensor adapted to detect torque generated on the supporting unit.
