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 ...

The WalkTrainer: A Robotic System for Walking Rehabilitation

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

Standard reeducation methods for paraplegic people rely on manual or robotic mobilization on a treadmill. However in both cases the motion is generated by an exterior force, the training is thus called passive. In this context the Swiss Fondation for Cyber ...
