In this paper we present a new approach of Internet-based teleoperation applying calibrated
virtual reality. The limited technical performance of the Internet in terms of bandwidth,
delay, jitter and reliability make necessary to introduce new methods to provide clients
with applicable control environment through the network.
We are focusing on the negative effects of limited bandwidth and present solution
for a special class of telerobotic applications. Our approach to yield visual feedback
at remote places is based on the combination of calibrated virtual reality and multi-resolution
video streaming media. Utilizing the most a-priori information about the manipulation
area is essential to reduce the amount of data to be transmitted.
Our methods were proven effective during the evaluation of a teleoperated mobile micromanipulator
workstation, which has been developed at the Budapest University of Technology and
Economics. This system is capable of providing the human operator with real-time remote
access to a microrobot through a web browser running on any Internet-connected computer.
In this paper we present our results and introduce the mentioned telerobot system.
