ABSTRACT A positioning apparatus for use in positioning an arm of an industrial robot in angular and linear positions. The apparatus comprises a frame member connectable to an arm of an industrial robot during use of the positioning apparatus, a frame-supporting member connected to and supporting the frame member, and a base having an upstanding hollow sleeve portion. The frame- supporting member is mounted within the base hollow sleeve portion to undergo linear movement and angular movement, by means of a bearing between an outer peripheral surface portion of the frame-supporting member and an inner peripheral surface portion of the base hollow sleeve portion for slidably mounting the frame-supporting member to undergo linear and angular sliding movements. Linear drive means are provided for effecting linear driving movement of the frame-supporting member and angular drive means are provided for effecting angular driving movement of the frame-supporting member. The apparatus is rugged but enables a more precise positioning of the arm, since closer tolerances can be employed.
