Development of SCARA-Type Haptic Device for Electrostatic Non-Contact Handling System

This paper describes the development of a SCARA-type haptic device, which will be used to assist a human operator in non-contact object handling of silicon wafers using electrostatic levitation. The device has three degrees of freedom, of which only one (v ...

Acceleration and inclination sensors based on magnetic levitation

François Barrot

Some fields such as the Monitoring of Civil Engineering Structures, need very sensitive acceleration and inclination sensors with a high resolution at low accelerations (typically less than 1G) and moderate frequencies (typically less than 20 Hz) or very s ...

Two degrees of freedom miniaturized gyroscope based on active magnetic bearings

Thomas Bosgiraud

The introduction of the active blocking system, better known as ABS, into cars revealed the growing need for inertial sensing. Among other data, that permit to apprehend the movements of a vehicle, the measurement of the vehicle angular velocity describes ...

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 ...

Preliminary Investigations on a Diamagnetically Levitated Linear Conveyor

Hannes Bleuler, Dominique Chapuis, Roland Moser, 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 ...
