Date Jun. 21, 1984.Movable link device with a plurality of freedom degrees between a carrier element (manipulator arm or the like) and a carrier element (tool, and particularly gripping tool). The device comprises a support frame (1) adapted to be secured to the carrier element, a movable frame (2) to which the carried element is fixed, a plurality of jacks (5, 6, 7, 7', 8) arranged between the support frame (1) and the movable frame (2) so as to maintain the latter with respect to the former in a relative position as a function of the deformation states of said jacks, and remote control means (13) to control the jacks and comprising a variable capacity tank associated to each jack and forming therewith a closed fluid circuit. The invention is applicable to robotics in order to move a member with high power and precision. |
