Development 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 ...

A 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 ...

Design, manufacturing and implementation of a novel 2-axis force sensor for haptic applications

Reymond Clavel

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 ...

Design 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 ...

Phase-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 ...

Development 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 ...

Mechanical 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 ...

Design 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 ...

Modular methodology to design high precision parallel robots and application to a 5-Degree of Freedom flexure-based manipulator

Reymond Clavel, Murielle Richard

This paper presents a novel modular methodology to design ultra-high precision parallel robots. It chiefly aims at significantly decreasing both the complexity of their synthesis and their development time. This approach can be compared to a robotic Lego®, ...

Mechanical 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 ...
