The electronic wedge brake system (EWB) used in the automotive industry is a new structure designed for brake-by-wire systems. This paper proposes novel EWB which mainly composed of screw-driven wedged inner pad, fixed outer caliper-flexible rotor and hybrid stepper motor. proposed does not have planetary gear set or ball screw mechanism, it simplified existing to take advantage self-interlocki...

This paper presents a control architecture for redundant and compliant robots inspired by the theory of biological motor primitives which are theorised to be the mechanism employed by the central nervous system in tackling the problem of redundancy in motor control. In our framework, inspired by self-organisational principles, the simulated robot is first perturbed by a form of spontaneous moto...

This paper describes recent precision positioning technology. First, recent precision positioning mechanisms are introduced. Although ball screw mechanisms are widely used in industrial machines, the use of linear motors and the development of planar motors recently increase. Several linear motor mechanisms show the acceleration higher than 10G. The linear motor mechanism developed in my group ...

conclusions lack of difference in self-esteem of disabled people in different degrees of disability and in both men and women suggests that disabled people should not be presumed to have low self-esteem, and their different aspects of life should be attended to, just like others. furthermore, studies should be designed and implemented based on psychological, social and environmental factors tha...

BACKGROUND Developmental milestone markers for fine motor and self-care skills among children with Down syndrome (DS) are either minimal, anecdotal or out-of date. Our goal was to produce normative expectations for the development of fine motor and self-care milestones specific to children with DS. METHOD A cross-sectional retrospective chart review was completed on 274 children with DS seen ...

Detecting motor imagery activities versus non-control in brain signals is the basis of self-paced brain-computer interfaces (BCIs), but also poses a considerable challenge to signal processing due to the complex and non-stationary characteristics of motor imagery as well as non-control. This paper presents a self-paced BCI based on a robust learning mechanism that extracts and selects spatio-sp...

Neuronal underpinnings of auditory verbal hallucination remain poorly understood. One suggested mechanism is brain activation that is similar to verbal imagery but occurs without the proper activation of the neuronal systems that are required to tag the origins of verbal imagery in one's mind. Such neuronal systems involve the supplementary motor area. The supplementary motor area has been asso...

Bchavior imitation ability will he a key technology for future human friendly robots. In order to understand the principles and mechanisms of imitation, we take B synthet,ic cognitive developmental approach, starting with minimum components and create a system that can learn to imitate others. We developed a visuomotor neural learning system which consists of orientation selective visual moveme...

cerebral palsy is a term commonly used for conditions characterized by motor dysfunction due to non-progressive brain damage in early life. the aim of this study was to compare the effects of self-control and experimental-control feedback frequencies on the acquisition, retention and transfer of a throwing task in children with spastic cerebral palsy. from 1750 students with cerebral palsy in t...
