Autonomous system and method for determining information representative of the movement of an articulated chain
First Claim
1. An autonomous system for determining items of information representative of the movement of an articulated chain comprising at least two solid elements and at least one articulation connecting said two elements, said system being characterized in that it comprises:
- at least two devices for measuring inter-device distances between the at least two devices, mounted fixedly each on a respective distinct element of said articulated chain and suitable for transmitting the measurements made;
means for determining at least one distance separating the at least two measuring devices based on at least one measurement supplied by at least one of the two measuring devices; and
calculation means, suitable for calculating items of information representative of the movement of said articulated chain based on the distances transmitted by said distance-determination means.

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.

17. A method for determining items of information representative of the movement of an articulated chain comprising at least two solid elements and at least one articulation linking said two elements, characterized in that it comprises the following steps:
-
fixedly mounting at least two distance-measuring devices each on a respective distinct solid element of the articulated chain; determining at least one distance based on at least one measurement supplied by at least one of the two distance-measuring devices; and calculating items of information representative of the movement of said articulated chain based on the previously-determined distances.
