Patent number: 7281447Abstract: A link with a transmission cable (14) between a driving pulley (15) and a driven pulley (22) causing a mobile unit (5) to rotate, has two strands (23, 24) connecting the driven pulley (22) with idle pulleys (17, 18) which are substantially aligned with an axis (Y) of rotation of an part (2) intermediate to the unit (5) and to the base (1) on which the motor (12) is secured. Thus, the motor (12) is positioned on optionally fixed parts and rotation of the support (2) has only very little effect on the tension of the cable (14), so that it may always work properly. The invention is especially applied to articulated robot arms.Type: GrantFiled: November 15, 2002Date of Patent: October 16, 2007Assignee: Commissariat a l'Energie AtomiqueInventors: Florian Gosselin, Alain Riwan, Dominique Ponsort

Publication number: 20060207377Abstract: A control or robot articulated arm comprising motorised articulations, at least some of which are remote controlled by motors (15, 16) place on a base (3) to lighten the arm. The motors (15 and 16) are side by side and control coaxial pulleys (12 and 13) due to bulges (24, 25) at stages on the motor shafts (17 and 18). This reduces the overall size.

Publication number: 20040099081Abstract: This master arm comprises a wrist (6) held at a constant global inclination to achieve excellent decoupling of translation controls accomplished by moving segments (3, 4) and rotation controls, accomplished by turning the wrist. The operator's task is facilitated and kinetic singularities are almost entirely eliminated. One special embodiment comprises a wrist holder (5) and a special link (18 to 22) that connects the wrist holder to a fixed base; and moving elements (7, 8, 9) of the wrist (6) have hinge pins meeting at a point (0). Thus, the wrist (6) is balanced in rotation and applies a constant force on the segments (3, 4) of the arm, so that they can easily be balanced by a static feedback means. Therefore, the arm can remain in a stable position even when it is released.Type: ApplicationFiled: November 12, 2002Publication date: May 27, 2004Inventors: Alain Riwan, Dominique Ponsort
