Stable Control

This paper proposes a passivity theorem on the basis of energy concepts to study the stability of force feedback in a virtual haptic system. An impedance-passivity controller (IPC) was designed from the two-port network perspective to improve the chief drawback of haptic systems, namely the considerable time required to reach stability if the equipment consumes energy slowly. The proposed IPC can be used to achieve stability through model parameter selection and to obtain control gain. In particular, haptic performance can be improved for extreme cases of high stiffness and negative damping. Furthermore, a virtual training system for one-degree-of-freedom sticking was developed to validate the experimental platform of our IPC. To ensure consistency in the experiment, we designed a specialized mechanical robot to replace human operation. Finally, compared with basic passivity control systems, our IPC could achieve stable control rapidly.

Haptic Sensation

Use of force feedback, or haptics, has increased the realism of virtual reality simulation systems over the last few years. In this research we propose a framework for the communication of haptic sensation in a shared environment over the Internet for developing novel manufacturing training system. This framework allows re-experiencing the sensation at geographically remote location by transmitting the haptic information over a TCP/IP network. We call this Tele-haptics. Using Tele-haptics, we propose a system where we can capture skill sets commonly associated with complex tasks such a die and tool polishing and communicate this to trainee over the internet. The trainee, using a Phantom Haptic system, can experience the process of polishing based on the master’s input. The framework for haptic communication is experimentally evaluated. The results of the experimental evaluation suggest that it is possible to transmit and recreate haptic features such as geometry and force characteristics.

High Level

The results of a survey of 54 persons with upper limb amputations who anonymously completed a questionnaire on an Internet homepage are presented. The survey ran for four years and the participants were divided into groups of females, males, and children. It was found that the most individuals employ their myoelectric hand prosthesis for 8 hours or more. However, the survey also revealed a high level of dissatisfaction with the weight and the grasping speed of the devices. Activities for which prostheses should be useful were stated to include handicrafts, personal hygiene, using cutlery, operation of electronic and domestic devices, and dressing/undressing. Moreover, additional functions, e.g., a force feedback system, independent movements of the thumb, the index finger, and the wrist, and a better glove material are priorities that were identified by the users as being important improvements the users would like to see in myoelectric prostheses.
