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.
