Sensorless microrobotic wrist

CTI project in collaboration with a Swiss industrial partner

Test bench for force measurement on a piezoelectrical cantilever.

Test bench for force measurement on a piezoelectrical cantilever.

Project description

The aim of the project is to develop a muti-degrees of freedom piezo-based robotic wrist providing positioning and force sensing capabilities at submicron scale. In order to keep the wrist dimensions very compact (< 2 cm3), the Integrated Actuator Laboratory (LAI) investigates the possibility to make use of sensorless actuation technologies.
