Abstract: Disclosed are a joint module and a joint robot. The joint module includes a mounting shell and a joint body. The mounting shell includes a joint mounting portion and an input sleeve which are connected to each other. The central axis of the joint mounting portion is perpendicular to the central axis of the input sleeve. The joint body is provided with an output cover. The central axis of the joint mounting portion is perpendicular to the central axis of the input sleeve, and the projection of the output cover on the input sleeve does not protrude out of the peripheral edge of the input sleeve, thereby enabling the overall appearance of the joint module to be regular and compact, and reducing mutual interference between the joint module and the external environment, so as to improve the application effect of the joint module.
