The structure has a displacement unit to move in translation and rotation an arm (40) along and around a main axis (Z) with respect to a frame (2). The unit has motors (12, 22) engaged with a hollow shaft (32) for moving the shaft in translation and rotation along and around the axis with respect to the arm or the frame. A reception unit (70) e.g. strap, of a tool (72) e.g. robot gripper, is movable with respect to the arm. A harness (80) has cables supplying power to the tool and the motors, and is extended from the frame towards the arm via the shaft. |
