The LIRMM (Montpellier Laboratory of Computer Science, Microelectronics
and Robotics) in France is seeking (again) a candidate for a PhD founded
by ETEL Motion Technology, in Switzerland.
Only high-standing candidatures will be considered.
Phd Subject Title
Towards pick-and-place machines with very high accuracy and dynamics
High precision industries, such as semi-conductor industry, are in need
of machines combining high accuracy and high throughput. To date this
need has been covered mostly by standard equipment such as X-Y tables;
however this approach is now reaching its limits in terms of maximum
speed and acceleration. On the other hand, robots have been designed for
pick-and-place industries which can reach very impressive accelerations
but none of them have demonstrated enough accuracy to satisfy the
semi-conductor industry requirements.
Indeed designers are facing two scientific and technological barriers:
serial machines suffer from high inertias limiting their acceleration
capability; parallel mechanisms suffer from poor stiffness limiting
This thesis aims at advancing those frontiers and will be developed in
synergy between the ETEL Company (Switzerland) and LIRMM (France).
At first the research work will be guided by generic needs coming from
industrial applications. Starting from this, innovative concepts of
kinematics, actuation systems, measurement and control strategies should
be searched for. Modeling of various inaccuracy sources (joints,
transmissions, vibrations, control, etc) should be carried out so that
their impact on the global system can be clearly understood. In this
research work, both mechanical design and control issues should be
investigated. Along the project, assessment of results and proof of
concepts should be made by designing and operating prototypes.
ETEL is the world’s leading supplier for direct drive and motion systems
with research, development and production facilities in Môtiers,
Switzerland; LIRMM is a joint laboratory of Université Montpellier 2 and
CNRS, and is installed in Montpellier, France. Research will be mostly
done in Montpellier but frequent visits and stays in Môtiers are
foreseen. Ph.D. dissertation shall be written in English to facilitate
dissemination among ETEL employees.
Academic adviser will be Dr. François PIERROT
Co-academic adviser and contact at LIRMM will be Dr. Sébastien Krut

Industrial contact at ETEL will be Dr. Samir Bouabdallah,
