Abstract

A server-decentralized Internet model based on Jabber for robot tele-operation with P2P stream media transfer supplement based on JXTA is proposed. The system is composed of four components: operators, robots, transfer servers and data-keeper. The robot-controlling data/robot state data are packed with XML stanzas and delivered to the resolved robot/operator through XML streams. The locale audio/video media streams of the robot are sent directly through P2P pipes to the operators. In order to test its availability and performance, the model is implemented and instanced as remote control systems for Virtual Puma560 robot and the Hexapod Monster robot. Experiments of the systems and network tests are carried out to evaluate the instances; the results show that the systems are suitable for many kinds of robot tele-operation scenarios despite the tough network environment.
