This paper describes a novel distributed networked architecture for an intelligent robot. It is proposed to address two challenges for an Internet/LAN based robot system: (1) how to utilize the networked resources of perception and computation, and (2) how to realize a dynamic structured and updateable robotic system. In this architecture, a generic distributed robotic framework evolved from hybrid robotic architecture is proposed, to integrate an autonomous robot into a distributed network structure. A distributed computing infrastructure and the spontaneous and PnP connection mechanisms are realized, which implement the scheme of distributed computation and information for the networked robot system.

To find new approaches to the stability and synchronization problems of Internet based telerobotic systems, a mission/behavior based robotic teleoperation scheme is proposed. A novel distributed perception strategy is presented to enable the robot to autonomously search and utilize sensors via the Internet. These two schemes are implemented in the Distributed Architecture for Internet Robot (DAIR) design. In this paper, the mechanism, utilization and explanation of these two schemes are given. Experiments have proved their feasibility and effectiveness for both performance improvement in teleoperation and intelligence advancement in Internet based robotic systems.
