Modeling and compensation of cutting-forces generated during the EDM process for ultra high-precision robots

Reymond Clavel, Emanuele Lubrano, Adrian Ionut Prodan

This work deals with the calibration of industrial robots operating at sub-micrometric precision. We demonstrate that the cutting-forces generated by the robot manufacturing process cause a significant deformation of the robot geometry, lo- wering its abso ...

Thermal Calibration of a 3 DOF Ultra High-Precision Robot Operating in Industrial Environment

Reymond Clavel, Emanuele Lubrano

While dealing with sub-micrometer precision robots, thermal expansion is the most significant source of inaccuracy. Thermal variations in the environment, in the robot parts and in the frame change the robot geometry, lowering the robot precision. In this ...

Thermal Behavior of an Ultra High-Precision Linear Axis Operating in Industrial Environment

Reymond Clavel, Emanuele Lubrano

Thermal expansion is the major source of inaccuracy for ultra high-precision robots. In this paper we propose a strategy to model and compensate this effect. The experiment is run using a 1 DOF (degree-of-freedom) parallel robot equipped with ten temperatu ...

Clinical Trials with the WalkTrainer: Preliminary Results

Reymond Clavel, Mohamed Bouri, Jacques Fournier, Yves Stauffer, Patrick Métrailler, Yves Allemand

Robotic devices are well suited for providing motion to the patient and information (positions, forces, etc.) to the therapist. The FSC and LSRO are combining their effort in the development of robotic re-education devices, focusing on active rehabilitatio ...

Pelvic motion measurement during over ground walking, analysis and implementation on the WalkTrainer reeducation device

Reymond Clavel, Mohamed Bouri, Jacques Fournier, Yves Stauffer, Patrick Métrailler, Yves Allemand

Pelvic motions are of great importance while walking, and have thus to be taken into account when developing and controlling rehabilitation devices. This paper will first introduce a new reeducation devices for paraplegic people: the WalkTrainer. This devi ...
