Conception and Construction of a 3 DOF Optical Precision Sensor Integrated in Micro-Robots

This diploma project’s goal was to develop a low-cost 3 DOF position sensor of small dimension that permits to find the position and orientation of the actuated object and thus, enable a closed loop control in 3 DOF. The range in X and Y should be at least ...

Applications of piezo-actuated micro-robots in micro-biology and material science

Jean-Marc Breguet, Walter Driesen, Tomas Cimprich

This paper presents a few examples of manipulators and micro-robots based on piezo-actuators developed during the last 4 years in the Laboratoire de Systèmes Robotiques (LSRO) at EPFL. Three working principles will be described (bender, inch-worm, inertial ...

Dynamical Modelling and Position Control of Ultrasonic Piezoelectric Positioning Stage

Jean-Marc Breguet, Tomas Cimprich

The paper describes development of a feedback position controller for a new type of monolithic "hybrid" ultrasonic motor. The goal of the controller design was to demonstrate the main advantage of this piezoelectric motor – high speed and high accuracy at ...

Ultrasonic monolithic piezoelectric multi DOF actuators for mobile microrobots

Jean-Marc Breguet, Walter Driesen, Tomas Cimprich

We propose a new type of “hybrid” ultrasonic driving principle for our monolithic piezoelectric actuators, which consist of simple electrode patterning on a PZT ceramic substrate The operating principle of the proposed USM is based on the conversion of ell ...

ELECTRONIQUE EMBARQUEE POUR LE CONTROLE DE MICROROBOTS MOBILES SANS FILS

Reymond Clavel, Tomas Cimprich, Pascal Wey

Dans le cadre de projets européens, le LSRO a développé de nombreux micro-robots mobiles de très haute précision fonctionnant sur le principe du stick-slip et de l’ultrasonique. Cependant, la génération de signaux et le contrôle se font bien souvent par un PC et des équipements encombrants externes au micro-robot. L’étudiant a été chargé de concevoir et d’implémenter, à l’aide d’un microcontrôleur, l’électronique de la génération de divers signaux et de développer une communication sans fil.
