Patent number: 7698966Abstract: The control unit includes an arm (21) sliding inside of a sheath (20) the angle of which can be varied and which is supported by three tensed cables (25; 26; 27) arranged in a triangle and unwinding with a certain degree of resistance from force feedback motors (16; 17; 18). The wrist (23) of the control unit can be moved according to at least the three degrees of translational freedom, without having to be afraid of encountering the cables; the control unit is simple, inexpensive and possesses a satisfactory degree of stiffness. A friction-creating means, possibly consisting of another tensed cable and dependant on a motor, is placed between the sheath (20) and the arm (21). This unit can be used for telemanipulation, telesurgery, CAD, games, etc.Type: GrantFiled: December 6, 2002Date of Patent: April 20, 2010Assignee: Commissariat A l' Energie AtomiqueInventor: Florian Gosselin

Patent number: 7474198Abstract: An actuation block for a train of segments, that can be used as a manual interface terminating by a finger grip (31) of the user, comprises a base (1) fixed to the hand or arm of the user and two or three motors (5, 32) oriented so that their main extension direction, or the direction of their output shaft, is parallel to a first pivoting segment (16) of the train. The actuation block is thus compact. Applications may include control arms or, on the contrary, force return arms.Type: GrantFiled: December 14, 2004Date of Patent: January 6, 2009Assignee: Commissariat a l'Energie AtomiqueInventors: Florian Gosselin, Tanguy Jouan-De-Kervenoael, Christian Dechelle

Patent number: 7392722Abstract: This controller, between a fixed base (1) and a control handle (4), comprises three similar arms (2) of which each comprises three links (5,6,7) jointed between the base and the handle platform by a pivot (8), two rotation joints (9 and 10) and a ball-joint (11). This controller with six degrees of freedom includes force feedback motors at the first and second joints (8 and 9) of which the first is fixed to the base (1) and the second to the first link (5), so that the first is immobile and the other has scarce movement; the third joint (10) is free. The resulting structure is simple and light not requiring any parallelogram, and kinematic singularities are greatly reduced.Type: GrantFiled: January 20, 2003Date of Patent: July 1, 2008Assignee: Commissariat A l'Energie AtomiqueInventors: Florian Gosselin, Eric Villedieu, Jean-Pierre Friconneau

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
