Patent number: 10830582Abstract: A method for compensating for accuracy errors of a hexapod is disclosed, said hexapod comprising a base, an actuation assembly having six linear translation actuators, a control unit, and a movable carriage comprising a platform connected to the base by means of the actuation assembly. The method includes a measurement step for determining geometry and positioning errors on the hexapod, the measurement step including sub-steps for determining positioning errors of the pivot centers on the carriage and on the base, for determining length errors of the actuators and for measuring positioning errors of the actuators along the path thereof, the compensation method also including a step for calculating, from measurements taken, error compensation values and a step for applying said error compensation values to the control unit of the hexapod, during subsequent use of said hexapod.Type: GrantFiled: October 5, 2016Date of Patent: November 10, 2020Assignee: MICRO-CONTROLE SPECTRA-PHYSICSInventors: Eric Durand, Franck Duquenoy

Patent number: 10001194Abstract: A driving device for driving in rotation a toothed wheel, in particular a turntable, has a worm intended to mesh with the toothed wheel, a motor to drive the worm in rotation, a flexible sleeve that partially surrounds the worm in such a way as to form an assembly described as a worm/sleeve assembly, and a pre-stressing unit. The motor is arranged in a structure that is fitted pivotably relative to the worm/sleeve assembly, and the driving device also has a force transfer unit connecting the motor to the sleeve at a second extremity of the worm.Type: GrantFiled: January 23, 2014Date of Patent: June 19, 2018Assignee: Micro Controle-Spectra PhysicsInventors: Eric Durand, Bruno Rety

Publication number: 20160271790Abstract: A system provides for relative movement between two plates that are substantially parallel to a plane defined by a first direction and a second direction. The system includes a first unit that is configured to allow a relative movement between the two plates in a third direction that is orthogonal to the plane. The first unit also independently prevents a relative movement between the two plates in the plane. The system further includes a second unit that is configured to allow one plate to relatively travel with respect to the other plate about the first and second directions.Type: ApplicationFiled: March 16, 2016Publication date: September 22, 2016Applicant: MICRO-CONTROLE SPECTRA-PHYSICSInventors: Bertrand de Saint Leve d'Aguerre, Alain Jeanne
