A high torque limited angle compact and lightweight actuator that comprises a driven pulley (11), a flexible tie-member (6), which is wound about the driven pulley (11), a linear actuator (7) and an inversion mechanism (8). In particular, the linear actuator (7), which is located with respect to the driven pulley (11) such that the direction is substantially tangent to it, comprises a movable element (10) that carries out a linear movement along a line according to two opposite directions (10′), (10″). The inversion mechanism is such that when an input portion (8′) moves along a line (first straight line), tangential to the driven pulley, of a certain an amount a output portion (8″) moves along another line (second straight line), which is also tangential to the driven pulley, for a same movement amount, such that the total length of the tie-member (6) is unchanged.

The invention relates to an autonomous system for determining items of information representative of the movement of an articulated chain (CA—1, CA—2, CA—3) comprising at least two solid elements (ES1—1, ES2—1, ES1—2, ES2—2, ES3—2, ES1—3, ES2—3, ES3—3, ES4—3) and at least one articulation (ART1—1, ART1—2, ART2—2, ART1—3, ART2—3, ART3—3) connecting said two elements. The system comprises at least two devices (DISP1—1, DISP2—1, DISP1—2, DISP2—2, DISP3—2, DISP1—3, DISP2—3, DISP3—3, DISP4—3) for measuring inter-device distances, mounted fixedly on two distinct elements of said articulated chain and suitable for transmitting the measurements made. Moreover, the system comprises means for determining at least one distance separating two measuring devices based on at least one measurement supplied by a measuring device, and calculation means (CALC), mounted on said articulated chain, suitable for calculating items of information representative of the movement of said articulated chain based on the measurements transmitted by said devices for measuring inter-device distances.

Strokes affect thousands of people worldwide leaving sufferers with severe disabilities affecting their daily activities. In recent years, new rehabilitation techniques have emerged such as constraint-induced therapy, biofeedback therapy and robot-aided therapy. In particular, robotic techniques allow precise recording of movements and application of forces to the affected limb, making it a valuable tool for motor rehabilitation. In addition, robot-aided therapy can utilise visual cues conveyed on a computer screen to convert repetitive movement practice into an engaging task such as a game. Visual cues can also be used to control the information sent to the patient about exercise performance and to potentially address psychosomatic variables influencing therapy. This paper overviews the current state-of-the-art on upper limb robot-mediated therapy with a focal point on the technical requirements of robotic therapy devices leading to the development of upper limb rehabilitation techniques that facilitate reach-to-touch, fine motor control, whole-arm movements and promote rehabilitation beyond hospital stay. The reviewed literature suggest that while there is evidence supporting the use of this technology to reduce functional impairment, besides the technological push, the challenge ahead lies on provision of effective assessment of outcome and modalities that have a stronger impact transferring functional gains into functional independence.

This paper proposes an augmented reality based exoskeleton for virtual object assembly training. This proposed hand exoskeleton consists of 9 DOF joints which can provide force feedback to all 5 fingers at the same time. This device has ability to simulate shape, size, and weight of the virtual objects. In this augmented reality system, user can assembly virtual objects in real workspace which is superimposed with computer graphics information. During virtual object assembly training, user can receive force feedback which is synchronized with physics simulation. Since this proposed system can provide both visual and kinesthesia senses, it will help the users to improve their assembly skills effectively.
