Position Controlled Diamagnetic Linear Conveyor

Hannes Bleuler, Dominique Chapuis, François Barrot, Thomas Bosgiraud, Benjamin Burns

Magnetic levitation is an interesting concept in applications where friction and wear-particle contamination should be avoided. In this respect, a former study has shown that diamagnetic levitation, in conjunction with an electrodynamic impulse drive, is a ...

Active Mechatronic Interface for Haptic Perception Studies with Functional Magnetic Resonance Imaging: Compatibility and Design Criteria

Hannes Bleuler, Roger Gassert, Dominique Chapuis, Etienne Burdet

Functional brain exploration methodologies such as functional magnetic resonance imaging (fMRI) are critical tools to study perceptual and cognitive processes. In order to develop complex and well-controlled fMRI paradigms, researchers are interested in us ...

Investigation of a Cable Transmission for the Actuation of MR Compatible Haptic Interfaces

Hannes Bleuler, Roger Gassert, Dominique Chapuis, Etienne Burdet, Ganesh Gowrishankar

This paper investigates a cable transmission to remotely actuate MR compatible robots over a distance of several meters. Such a transmission could be an interesting solution for haptic interfaces for neuroscience studies performing force feedback during fu ...

A 2-DOF fMRI compatible haptic interface to investigate the neural control of arm movements

Hannes Bleuler, Roger Gassert, Dominique Chapuis, Etienne Burdet, Olivier Lambercy, Ludovic Dovat, Yves Ruffieux

This paper describes a two-degrees-of-freedom haptic interface to investigate the brain mechanisms of human motor control, which is capable of safely and gently interacting with human arm motion during functional magnetic resonance imaging (fMRI). A hydros ...

Actuation Methods for Applications in MR Environments

Hannes Bleuler, Roger Gassert, Dominique Chapuis, Etienne Burdet, Ludovic Dovat

The choice of an adequate actuation method is a central issue in the development of any mechatronic device and strongly determines the dynamic performances of the system. This choice is particularly difficult for robotic systems working within a magnetic r ...

Preliminary Investigations on a Diamagnetically Levitated Linear Conveyor

Hannes Bleuler, Roland Moser, Dominique Chapuis, François Barrot, Laurent Sache, Thomas Bosgiraud

Diamagnetic levitation is the only passive levitation at room temperature. It is interesting to use this principle for a contactless conveyor in applications where friction and wear-particle contamination should be avoided such as in a microfactory. Using ...

FMRI compatible haptic interface actuated with traveling wave ultrasonic motor

Yves Perriard, Roger Gassert, Dominique Chapuis, Markus Flückiger, Matteo Bullo

We are developing haptic interfaces compatible with functional Magnetic Resonance Imaging (fMRI) for neuroscience studies. The presented prototype with one rotary degree of freedom is actuated by a traveling wave ultrasonic motor operating under admittance ...
