Abstract
Embodiments of the disclosure provide a joint apparatus for a robot and a robot. The joint apparatus includes a base; an output component arranged to be rotatable about mutually perpendicular three axes for three-degree-of-freedom motion, the output component comprising an outer peripheral portion; a first motor arranged on the base and comprising a first output shaft that rotates about a first axis of the three axes; a first transmission assembly having a first input end fixedly coupled to the first output shaft, a first output end rotatably coupled to the outer peripheral portion; and a composite drive assembly fixedly coupled to the first transmission assembly and comprising a second output end and a third output end rotatably coupled to the outer peripheral portion to drive the output component to rotate about a second axis and a third axis of the three axes.
