Robot PbD started about 30 years ago, growing importantly during the past decade. The rationale for moving from purely preprogrammed robots to very flexible user-based interfaces for training the robot to perform a task is three-fold. First and foremost, P ...
It is clear to all, after a moments thought, that nature has much wemight be inspired by when designing our systems, for example: robustness, adaptability and complexity, to name a few. The implementation of bio-inspired systems in hardware has however bee ...
The effect of motor training using closed loop controlled Functional Electrical Stimulation (FES) on motor performance was studied in 5 spinal cord injured (SCI) volunteers. The subjects trained 2 to 3 times a week during 2 months on a newly developed reha ...
Most of the Central Pattern Generator (CPG) models are based on defining explicit dynamical systems and finding the appropriate parameters. In this paper, we propose a novel CPG model that is based on altering a nonlinear oscillator to obtain desired limit ...

The motor actions that can be witnessed as a virtuoso musician performs can be so fast, so accomplished, so precise, as to seem somehow superhuman. The musician has to produce the movements, monitor those they have already made and the subsequent result, c ...
We are developing haptic interfaces compatible with functional magnetic resonance imaging (fMRI) to study the brain mechanisms of motor control in humans. This paper describes the different phases of our project, examines the constraints and presents possi ...
Recent developments in nanofabrication and optical near-field metrology have faced complementary modeling techniques with new demands. We present a surface integral formulation that accurately describes the extreme near-field of a plasmonic nanoparticle in ...

Robotic interfaces can dynamically interact with humans performing movements and can be used to study neuromuscular adaptation. Such devices can produce computer controlled dynamics during movement and measure the interaction force and movement trajectory. ...
Piezoelectric motors are resonant vibromotors. They represent a new actuator generation in the field of servo-drives. In particular, the travelling wave ultrasonic motor presents a high torque at low speed, a zero speed torque without feeding, low sensitiv ...
Digital color, by its ambiguous nature, which always oscillates between a writing and a sensation, is always shifting, elusive, intangible, and yet, well presents, through the increasing use of computers in every field. Since it seems impossible to solve n ...
