Wrist Coordination in a Kinematically Redundant Stabilization Task
Found in: IEEE Transactions on Haptics
By Lorenzo Masia,Valentina Squeri,Etienne Burdet,Giulio Sandini,Pietro Morasso
Issue Date:July 2012
pp. 231-239
We investigated how the control of a compliant object is realized by the redundancy of wrist anatomy. Subjects had to balance a one degree-of-freedom inverted pendulum using elastic linkages controlled by wrist flexion/extension (FE) and forearm pronation/...
Effect of Grip Force and Training in Unstable Dynamics on Micromanipulation Accuracy
Found in: IEEE Transactions on Haptics
By Eileen Lee Ming Su,Gowrishankar Ganesh,Che Fai Yeong,Chee Leong Teo,Wei Tech Ang,Etienne Burdet
Issue Date:July 2011
pp. 167-174
This paper investigates whether haptic error amplification using unstable dynamics can be used to train accuracy in micromanipulation. A preliminary experiment first examines the possible confounds of visual magnification and grip force. Results show that ...
Controlling a Wheelchair Indoors Using Thought
Found in: IEEE Intelligent Systems
By Brice Rebsamen, Etienne Burdet, Cuntai Guan, Haihong Zhang, Chee Leong Teo, Qiang Zeng, Christian Laugier, Marcelo H. Ang Jr.
Issue Date:March 2007
pp. 18-24
The idea of controlling objects or machines through thought is moving from science fiction to reality. This article presents the first working prototype of a brain-controlled wheelchair that can navigate in a typical office or hospital environment. The whe...
A Haptic Knob with a Hybrid Ultrasonic Motor and Powder Clutch Actuator
Found in: World Haptics Conference
By Dominique Chapuis, Xavier Michel, Roger Gassert, Chee-Meng Chew, Etienne Burdet, Hannes Bleuler
Issue Date:March 2007
pp. 200-205
In haptics, the forces to be displayed vary widely in terms of magnitude and bandwidth. A single actuator can hardly comply with these requirements. It has thus been proposed to combine electrical motors and passive devices in a hybrid actuator to cover a ...
Haptics of Buckling
Found in: World Haptics Conference
By Tim Poston, Ankur Dhanik, Etienne Burdet, Teo Chee Leong
Issue Date:March 2005
pp. 299-307
System delay in a haptic virtual world creates inappropriate instability and oscillations. An intrinsically unstable environment can give appropriate instabilities such as snap buckling. Around a buckling point the low-order approximations useful in soluti...
3DOM: A 3 Degree of Freedom Manipulandum to Investigate Redundant Motor Control
Found in: IEEE Transactions on Haptics
By Julius Klein,Nicholas Roach,Etienne Burdet
Issue Date:April 2014
pp. 229-239
This paper presents a novel robotic interface to investigate the neuromechanical control of redundant planar arm movements. A unique aspect of this device is the third axis by which the wrist, and hence the pose of the arm can be fully constrained. The top...
Book Review: Human Robotics:Neuromechanics and Motor Control
Found in: IEEE Transactions on Haptics
By Etienne Burdet,David W. Franklin,Theodore Milner,Herman van der Kooij,Edwin van Asseldonk
Issue Date:April 2014
pp. 270
This book is valuable in teaching the broad topic of human motor control. Includes some of the following topics: an overview of the physiology of the nervous system, peripheral sensory systems, and mechanics of the muscle-tendon complex; fundamental concep...
Exercises for rehabilitation and assessment of hand motor function with the Haptic Knob
Found in: Proceedings of the 3rd International Convention on Rehabilitation Engineering & Assistive Technology (i-CREATe '09)
By Christopher Kuah, Etienne Burdet, Hong Yun, Karen Chua, Ludovic Dovat, Olivier Lambercy, Roger Gassert, Seng Kwee Wee, Teo Chee Leong, Theodore Milner
Issue Date:April 2009
pp. 1-5
This paper investigates robot-assisted rehabilitation and assessment of hand function after stroke using the Haptic Knob, a 2 degrees-of-freedom end-effector based robotic device to train grasping and wrist pronation/supination. Nine chronic stroke subject...
