20100204804 | FOREARM ROTATION MECHANISM AND ORTHESIS WHICH INCLUDES SUCH A MECHANISM - Rotation mechanism for a forearm which includes a moving stay ( | 08-12-2010 |
20110098619 | SHOULDER MECHANISM FOR AN ORTHOSIS - The invention relates to a shoulder mechanism for an orthosis, providing a ball type joint between a support and an orthosis upper arm, comprising a first intermediate element mounted to pivot on the support about a first pivot axis, a second intermediate element mounted to pivot on the first intermediate element about a second pivot axis, the upper arm being mounted to pivot on the second intermediate element about a third pivot axis. According to the invention, the first pivot axis extends in a longitudinal horizontal direction, the first intermediate element including a circular rail on which the second intermediate element slides and that presents a geometrical axis defining the second pivot axis that extends vertically when the upper arm is at rest, the circular rail extending to go around the shoulder on the outside. | 04-28-2011 |
20120031164 | METHOD FOR FRICTION COMPENSATION IN A DEVICE WITH FORCE FEEDBACK PROVIDED WITH CABLE TRANSMISSION - A method of compensating friction in a force-feedback device comprising a control member manipulated by a user and coupled to a tensioned cable that is actuated by a motor and gearbox unit. The method includes the steps of (1) detecting a variation in the sag of the cable caused by a manipulation of the control member, and (2) in response to such a detection, controlling the unit so that it develops a force (Fa) that compensates, at least in part, for the internal friction (Rsa) of the unit that opposes movement of the control member manipulated by the user. | 02-09-2012 |

20130041641 | METHOD FOR IDENTIFYING FRICTION IN A HINGE OF A ROBOT ARM OR MANIPULATOR ARM, AND USE THEREOF IN A TORQUE COMPENSATION METHOD - An identification method for identifying the behavior of a hinge of a robot arm or of a manipulator arm, the method including the steps of selecting a behavior model linking the input torque and the output torque of the hinge depending on operating parameters, and of operating the hinge in such a manner as to measure several (input torque/output torque) operating points, and of performing a regression in order to identify the parameters of the model and thus to determine at least one of the direct or indirect characteristics of the hinge. The behavior model retained includes dry friction having a first component that does not depend on the output torque, and a second component that does depend on the output torque of the hinge. | 02-14-2013 |
