Optimal design of a squeeze film actuator for friction feedback

Yves Perriard, Yoan René Cyrille Civet, Christophe Winter

Sense of touch belongs to one of the five Human Senses. Whereas blind people largely use feeling in everyday life, sighted person mainly focus on hearing and vision. However, haptic interface started being introduced in customers applications, such as smar ...

Dielectric Elastomer Actuators for soft-grasping

Dario Floreano, Herbert Shea, Samuel Rosset, Jun Shintake, Bryan Edward Schubert

We demonstrate here a configuration of soft actuator which has several features such as, being completely soft, simple, thin, foldable, and stretchable while having uni/bidirectional bending actuation. Theoretically the actuation can be extended to multidi ...

Design of a Miniature Short-Stroke Constant-Force Linear Actuator

Yves Perriard, Romain David Besuchet

This paper presents the modelling, design and testing of a short-stroke linear actuator to be embedded in a battery-powered positioning device. The particularity of this small (1 cm3) electromagnetic actuator is that it has to provide a constant force alon ...

Multi-Finger Haptic Devices Integrating Miniature Short-Stroke Actuators

Grégory Savioz

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 ...

Linear multi-modal actuation through discrete coupling

Nitesh Maheshwari

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 ...

A bidirectional shape memory alloy folding actuator

Jamie Paik

This paper presents a low-profile bidirectional folding actuator based on annealed shape memory alloy sheets applicable for meso-and microscale systems. Despite the advantages of shape memory alloys-high strain, silent operation, and mechanical simplicity- ...

A soft robotic actuator using dielectric minimum energy structures

Dario Floreano, Herbert Shea, Samuel Rosset, Jun Shintake

Dielectric minimum energy structures are capable of large actuation stroke, and consist of a pre-stretched dielectric elastomer actuator (DEA) laminated onto a flexible frame, which makes it easy to obtain both simple and complex shapes. We report here on ...

Comparison of Cost Functions for Electrically Driven Running Robots

Roland Siegwart

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 ...

Large Hybrid High Precision MEMS Mirrors

Dara Zaman Bayat

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 ...

Modeling of the air film pressure for a haptic touch actuator

Yves Perriard, Christophe Winter

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 ...
