Robotic Assistance by Impedance Compensation for Hand Movements While Manual Welding

In this paper, we present a robotic assistance scheme which allows for impedance compensation with stiffness, damping, and mass parameters for hand manipulation tasks and we apply it to manual welding. The impedance compensation does not assume a preprogra ...

Cell Shape Dynamics Reveal Balance of Elasticity and Contractility in Peripheral Arcs

Jean-Jacques Meister, Chiara Gabella, Alexander Verkhovskiy, Benoît Vianay, Céline Jeanne Labouesse

The mechanical interaction between adherent cells and their substrate relies on the formation of adhesion sites and on the stabilization of contractile acto-myosin bundles, or stress fibers. The shape of the cell and the orientation of these fibers can be ...

End-point Impedance Measurements at Human Hand during Interactive Manual Welding with Robot

Aude Billard, Mustafa Suphi Erden

This paper presents a study of end-point impedance measurement at human hand, with professional and novice manual welders when they are performing Tungsten Inert Gas (TIG) welding interactively with the KUKA Light Weight Robot Arm (LWR). The welding torch ...

Laser micro-spot welding of copper by real-time process monitoring

Simone Amorosi

A new laser micro-spot welding procedure for copper has been developed in order to eliminate the shortcomings of existing techniques based on laser pulse shaping or in-situ temperature control. This procedure consists in dividing the welding process in fou ...
