Embodiments of the present disclosure provide a robot. The robot comprises a joint housing and an internal engaging member arranged on an inner surface of the joint housing; a second arm link comprising a flange; and a moving assembly at least partially arranged in the joint housing and comprising an input shaft adapted to rotate about an axis of the input shaft; and at least one intermediate member coupled to the output flange and adapted to be driven by the input shaft to rotate while engaging with the internal engaging member, to cause a relative movement between the first and second arm links. By integrating the relative static parts of the gearbox, such as the joint housing and the output flange to the robot arm links, high connection strength of connections between robot arm links can be achieved in a more cost-efficient and space-saving manner.
