The present invention relates to a robot arm including a control structure. The robot arm comprises: a moving base including a plurality of degrees of driving freedom; and a control module wherein one end is connected to the moving base. The control module comprises: a main body, a sleeve, a fixating device, and a connection unit. The main body is extended as a structure of a long band shape in one direction, wherein an extension direction is defined as an axial direction, and has a concave groove formed in an axial direction and a male thread on an outer surface. The sleeve includes a through hole overlapped on the male thread, and the through hole includes a protruding block facing the concave groove on an inner surface of the through hole. The protruding block is accommodated in the concave groove and limits the degree of freedom in which the sleeve and the main body respectively rotates; and the fixing device includes a through hole and a female thread installed in the inner surface of the through hole. The female thread is screwed to the male thread of the main body, and the fixing device is fixated to one side of the sleeve by the connection unit. |
