Tactile sensations have historically been hard to convey artificially. The range of possible sensations is much larger than other senses since the skin and the body itself have various sensory organs for different stimuli, such as dry/wet, hot/cold, hard/soft, pressure, position, vibration, and so on. Today, most feedback devices on the market are engineered to reproduce the mechanical sensatio...

Investigations have been performed on the dynamics of a distance regulation system based on an oscillating probe at resonance. This was examined at a tuning fork shear-force feedback system, which is used as a distance control mechanism in near-field scanning optical microscopy. In this form of microscopy, a tapered optical fiber is attached to the tuning fork and scanned over the sample surfac...

For practical application of force feedback in robotassisted surgical systems, it may not be possible to match the number of degrees of freedom of position sensing and control with the degrees of freedom of force sensing and feedback. The goal of this experimental study is to determine the effect of such sensor/actuator asymmetry during bilateral telemanipulation. We examined the performance of...

A self-tuning procedure is proposed for an active structural element with collocated sensing and actuation (a so-called ‘Smart Disc’). The procedure aims at optimal active damping by means of Integral Force Feedback control. In case the behavior of the structure to be damped may be described by a single dominant vibration mode, self-tuning is realized in two fairly simple steps: (1) recursive e...

This study was prompted by recent evidence for the existence of positive force feedback in feline locomotor control. Our aim was to establish some basic properties of positive force feedback in relation to load compensation, stability, intrinsic muscle properties, and interaction with displacement feedback. In human subjects, muscles acting about the wrist and ankle were activated by feedback-c...

A laparoscopic surgery system by using a robot holds many problems. Among these, its inability in delivering touching sensation to a surgeon is raised as the biggest problem. The current paper attempted to find a force feedback controlling method at the time of performing movement by using one-degree of freedom (DOF) arm of slave and master system that is used in the programming based system. T...

Aimed to develop a virtual robot aided surgery system which can represent the reality surgery process and realize force feedback by digital human tissue biomechanical information and outer force feedback instrument, human tissue geometrical and biomechanical modeling, biomechanical model calculation, force feedback instrument design, control algorithm are described. Finally, experiment was cond...
