The World Wide Web (WWW) provides a low-cost and widely-available interface that can make teleoperated resources accessible to anyone with WWW browser. In this study, we have developed a distance exhibition system on WWW using telerobotics technique. Distance exhibition system on WWW is a exhibition system that people can access via computer network using WWW browser and view the articles on exhibition of remote site.
We have designed and implemented architecture of distance exhibition system with intelligent mobile robot. Client program is separated from WWW browser for system extension. Server and client program divided into video image module and control module. Also, we have designed and implemented the data transmission protocols among system components.
Viewers are difficult to control remote devices effectively because transferred robot information is limited and network time delay occurs. To solve these problems, we have designed and implemented effective user interface and "approach command". Displaying sonar-based map of robot and camera viewing degree make users able to imagine exhibition environment. Robot can move to user's intended position by "approach command". This system helps users to control remote devices effectively.
