NETWORK CONNECTION MANAGEMENT SYSTEM FOR FAULT TOLERANT IN MODULE BASED PERSONAL ROBOT AND METHOD THEREOF, AND RECORDING MEDIUM THEREOF

摘要

A network connection management system for a module based personal robot, a network connection management method thereof, and a recording medium thereof are provided to perform a fault tolerant for connection between modules by detecting and reporting errors in the network connection. A module based personal robot system includes a middleware which supports plural open-type network interfaces and consists of a streaming layer, a network application layer, and a network interface layer. The navigation application layer includes an NAL(Network Application Layer) management unit(210), a local middleware information table(250), and a routing table(260). The NAL management unit manages a network connection manager and provides a naming service and a message routing service. The local middleware information table stores information on local middlewares. The routing table stores routing information. The NIL(Network Interface Layer) includes inner components having connection modules. When the network connection manager detects a network connection error, the error is reported to an upper level and the defective module is replaced with a normal module.
