Design, manufacturing and implementation of a novel 2-axis force sensor for haptic applications
Minimally invasive surgeries on the lungs have eliminated the ability for surgeons to place their hands on the patient's organ to feel for abnormalities. Therefore, in this paper, a force sensor for 2 degrees of freedom haptic applications is described. It ...
Elsevier Science Sa2014A Ball-Screw Driven Motorized Hip Orthosis
Hannes Bleuler, Reymond Clavel, Mohamed Bouri, Jeremy Olivier, Amalric Louis Ortlieb
In this paper we present a motorized hip orthosis to assist elderly people while walking, stair climbing and during the sit-to-stand transitions. The design is based on biomechanics considerations. Ranges of motion, velocities and torques of the hip joint ...
2014Development and integration of high straightness flexure guiding mechanisms dedicated to the METAS watt balance Mark II
Reymond Clavel, Florent Cosandier
There is a firm will in the metrology community to redefine the kilogram in the International System of units by linking it to a fundamental physical constant. The watt balance is a promising way to link the mass unit to the Planck constant h. At the Feder ...
Iop Publishing Ltd2014Phase-Shift Master-Slave Mechanisms for High Angular-Speed Wedge-Prism Systems
Reymond Clavel, Olivier Chappuis
Laser micro-machining requires high dynamic laser spot trajectory and accuracy to control the laser beam scanning. A well-known technique to scan a laser beam over a specimen is to use a pair of wedge-prisms. However, it is difficult to master-slave the ph ...
Taylor & Francis Inc2013Design of the new METAS watt balance experiment Mark II
Reymond Clavel, Florent Cosandier
The kilogram is the last unit of the international system of units (SI) still based on a material artefact, the international prototype of the kilogram (IPK). The comparisons made in the last hundred years have clearly revealed a long-term relative drift b ...
Iop Publishing Ltd2013Development of an Assistive Motorized Hip Orthosis
Hannes Bleuler, Reymond Clavel, Mohamed Bouri, Jeremy Olivier, Amalric Louis Ortlieb
With the increase of life expectancy, a higher number of elderly need assistance to maintain their mobility and their independance. The hip joint is crucial for walking and is problematic for a large number of aged people. In this paper we present a novel ...
2013Design and Calibration of Ultra-high-precision Industrial Robots
Reymond Clavel, Murielle Richard, Emanuele Lubrano
In this paper we present the key phases to design and calibrate ultra-high-precision industrial robots (i.e. submicrometric precision robots). The first part of our study will cover the robot design aspects, from the choice of the kinematics with the help ...
Institute of Electrical and Electronics Engineers2012Mechanical manipulator for surgical instruments
Hannes Bleuler, Reymond Clavel, Ricardo Daniel Rita Beira
A novel mechanical system, based on a new cable driven mechanical transmission, able to provide sufficient dexterity, stiffness, speed, precision and payload capacity to actuate multi-DOF micro-manipulators. Besides the possibility of being used in several ...
2012Mechanical positioning system for surgical instruments
Hannes Bleuler, Reymond Clavel, Ricardo Daniel Rita Beira
An external manipulator for positioning surgical instruments within the abdominal cavity, comprising a hybrid kinematics with a parallel structure, able to provide four, active or passive, positional degrees of freedom to a endoscopic unit, placed in the d ...
2012The Femtoprint Project
Yves Bellouard, Reymond Clavel, Jean-Marc Breguet
The Femtoprint project, a European project, aims at demonstrating the use of low-energy laser pulses (i.e. below the ablation threshold) to manufacture monolithically integrated devices including optofluidic, optomechanical and photonic devices. The longer ...
