A translational joint, sometimes called a 3-DOF joint, is shown in the diagram below with two reference frames at either end of the connection: x1y1z1on body 1, and x2y2z2on body 2. The translational joint allows free relative translation of the two frames, but constrains the relative rotation completely. Thus, the x2y2z2 axes remain parallel to the x1y1z1axes, respectively, during the motion of the system. The translation of the end frame, x2y2z2,relative to the start frame, x1y1z1,is represented by the vector, r, which is resolved into its three components in the x1y1z1 frame.
