Abstract

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.
