Sensory Feedback And Compliance
1984A common problem in robotics is to bring a tool to a certain spatial relationship to a workpiece, or to bring two or more components together into a certain spatial relationship. However, owing to accumulation of dimensional variation and tolerances that cannot be minimised at their source, errors can occur, making it unexpectedly difficult or ...

Accommodating to new ears: The effects of sensory and sensory-motor feedback
The Journal of the Acoustical Society of America, 2014Changing the shape of the outer ear using small in-ear molds degrades sound localization performance consistent with the distortion of monaural spectral cues to location. It has been shown recently that adult listeners re-calibrate to these new spectral cues for locations both inside and outside the visual field.

Sensory feedback for upper limb prostheses
2011In this chapter, we discuss the neurophysiological basis of how to provide sensory feedback to users with an upper limb prosthesis and discuss some of the theoretical issues that need to be considered when directly stimulating neurons in the somatosensory system. We focus on technologies that are currently available and discuss approaches that are most

Restorative Neurology and Neuroscience, 2015
Purpose: Musician’s dystonia (MD) is a task-specific movement disorder related to extensive expert music performance training. Similar to other forms of focal dystonia, MD involves sensory deficits and abnormal patterns of sensorimotor integration. The present study investigated the impaired cortical sensorimotor network of pianists who suffer from MD ...

Sensory Feedback in a Half-Center Oscillator Model
IEEE Transactions on Biomedical Engineering, 2007We hypothesize that one role of sensorimotor feedback for rhythmic movements in biological organisms is to synchronize the frequency of movements to the mechanical resonance of the body. Our hypothesis is based on recent studies that have shown the advantage of moving at mechanical resonance and how such synchronization may be possible in biology.

Sensory feedback for powered limb prostheses
Medical & Biological Engineering, 1975The results of these tests confirm that a prosthesis is easier to control with sensory feedback and that the proposed technique is acceptable to patients as well as to professionals working in this field. Work in this Institute is now directed toward development of the feedback system to a form suitable for inclusion in a prosthesis.

A myoelectrically-controlled prosthesis with sensory feedback
Medical & Biological Engineering & Computing, 1979An electrically-operated hand, controlled by myopotentials, has been fitted with strain gauges in the index finger which measure the gripping force between thumb and index finger. These strain gauges cause an electrical stimulus to be applied to the skin directly above the median nerve.

A learning-based approach to artificial sensory feedback
2015 American Control Conference (ACC), 2014The planning and control of even simple movements, such as reaching for an object, rely on somatosensory feedback of the state of the limb. Such feedback will be equally important for naturalistic control of neuro-prosthetic devices. For this reason, there has been considerable interest in the development of systems for artificial somatosensory ...

Sensory feedback for artificial limbs.
Medical progress through technology, 1979Over the years various approaches have been made to help solve the problem of replacing mechanical function of a lost limb, but there has been little direct interest in the associated problem of replacing the sensory function also lost in the amputation.

Sensory Feedback in locomotion control
2008This chapter focuses on the sensing processes and their interactions with locomotion control. The analysis has been accomplished taking into account different levels of behavior. Moreover dynamic simulators and robotic structures have been used to investigate the biological principles governing the sensory feedback in the real world.
