In the scope of haptic touch feedback actuators, we discuss the phenomenon of creating the haptic experience by squeezing the air film between the user finger and the actuator. The focus is given in the modeling of the squeeze film effect. An existing anal ...
The omnipresence of electronic devices in our everyday life goes together with a trend that makes us always more immersed during their utilization. By immersion, we mean that during the development of a new product, it is more and more required to stimulat ...
Due to technological limitations robot actuators are often designed for specific tasks with narrow performance goals, whereas a wide range of output and behaviours is necessary for robots to operate autonomously in uncertain complex environments. We presen ...
With the aim of providing a new touch sensation to the user, the design of innovative multi-finger haptic devices passes through the research for efficient and low-cost methods for position sensing. This paper thus addresses a novel self-sensing method for ...
Within the framework of a project consisting in developing a haptic keyboard, each key is aimed to be controlled individually in position and force. Small sized actuators has already been designed and integrated in a 64 keys force feedback keyboard. The pr ...
In this work we apply optimal control to create running gaits for the model of an electrically driven one legged hopper, and compare the results obtained for five different objective functions. By using high compliant series elastic actuators, the motions ...
This thesis presents the design and microfabrication technology of a tip-tilt, 2 degree of freedom "mirror system" made out of Silicon On Insulator (SOI) wafers with two movable mirrors that have diameter of 10 mm. The system was intended for precise beam ...
This paper presents a complete method for optimizing a linear actuator in order to perform its sensorless speed control. The optimizer maximizes the difference of inductances between two positions of interest in order to perform the efficient position dete ...

This project was done in the laboratory of integrated actuators (LAI) during the first master semester. It is part of a PhD-work with linear actuators, also called relays, where these actuators are optimized in design and equipped with a speed control duri ...
