The subject of the invention concerns an exoskeletal system with: an exoskeletal weight-bearing structure composed of a reference structure and at least one mechanical segment, resources for acquiring movements and movement intentions, composed of resources for time related measurement of the effort coming from at least one biological segment and time-dependent resources for detecting the direction of the movements or movement intentions of these segments, resources for acquiring the spatial position of the mechanical segments in relation to the reference structure, operating resources providing the motor-power for the articulated mechanical segments, and control resources connected at their inputs to the movement and position acquisition resources, and at their outputs to the operating resources in order to control them.

Using CMU actuators, a Prototype of Mechanical Assistance Device for the Wrist’s Flexion Movement (PMA) was developed and probed in a mechanical model, in order to be implemented in a future as a dynamic powered orthosis or as a rehabilitation assistant instrument. Two Mayor Actuators conformed by three CMU actuators arranged in a series configuration, allows to an artificial hand to be placed in four predefined positions: 0°, 20°, 40° and 60°. The synchronism and control of the actuators is achieved with the Programmable Control Module (PCM). It is capable to drive up to six CMU actuators, and possess two different modes of execution: a Manual mode and an Exercise mode. In the Manual Mode, the position of the hand responds directly to the commands of the keyboard of the front panel, and in the Exercise mode, the hand realizes a repetitive and programmed movement. The prototype was tested in 100 positions in the Manual Mode and for 225 works cycles in the Exercise Mode. The relative repetition error was less than 5% for both test. This prototype only consumes 4,15W, which makes it possible to be powered by small rechargeable batteries, allowing its use as a portable device.
