Internet-enhanced automation in micro environment

Developments in the Internet have significantly increased the human capability to reach and obtain information from remote locations. In parallel, the advent of micro sensors and actuators makes it possible for humans to sense and act in a micro-environment. Combined, the Internet and MEMS will produce a new technology for humans to sense and act in remote micro-environments, allowing the potential development of micro teleoperation and micro automation technologies. We present our ongoing development of polyvinylidene fluoride (PVDF) sensors that can be used for force-reflective control of micromechanical devices over the Internet. Internet based teleoperation between Hong Kong and Michigan State was demonstrated using an event-based control scheme, which ensured stability and synchronization. Control was enhanced by multimedia feedback, which included, in addition to the traditional video, force feedback.
