The main objective of this thesis is the accuracy improvement of parallel robots. Accuracy can be improved either by precise manufacturing and assembly or by calibration of each individual robot using a kinematic model which takes geometric deviations into ...
Designing effective behavioral controllers for mobile robots can be difficult and tedious; this process can be circumvented by using unsupervised learning techniques which allow robots to evolve their own controllers online in an automated fashion. In mult ...
Distributing control appropriately between man and machine is particularly pertinent to assistive technology. We use shared control techniques to augment wheelchair users’ capabilities, enabling them to safely perform precise manoeuvres. In this paper, we ...
Designing effective behavioral controllers for mobile robots can be difficult and tedious; this process can be circumvented by using unsupervised learning techniques which allow robots to evolve their own controllers in an automated fashion. In multi-robot ...
Because of their excellent olfactory sense, dogs are often used to find bombs, mines, drugs, or people buried by avalanches. For such applications, autonomous mobile robots could be used in the future. Electronic sensors already exist for a wide variety of ...
We propose a modular architecture for autonomous robots which allows for the implementation of basic behavioral modules by both programming and training, and accommodates for an evolutionary development of the interconnections among modules. This architect ...
A micromanipulation setup allowing comparative tests of manipulation micro tools has been developed. Repeatability measurements of positioning as well as optimization of manipulation conditions can be run with parts of typically 5 to 50μm over a large set ...
In the way of developing fast parallel robots, the following work proposes a development of a new delta robot. This robot is a 3 d.o.f. parallel robot based on a Delta-like kinematics [Clavel 88, 92]. It is actually an inverted Delta in which the parallel ...
This paper describes a software architecture for industrial robots used in manufacturing equipment. In order to achieve software portability, the application software is dissociated from the low-level robot controller software. The interaction between thes ...
This paper presents the latest results of a joint research project involving the Institute of Microengineering of the Swiss Federal Institute of Technology (Switzerland) and the Industrial Automation Laboratory of the Lyon National Institute of Applied Sci ...
