Abstract

A resource sharing architecture(RSA) is a robot architecture for a mobile robot in a networked and intelligent space. A robot based on a RSA performs its tasks by sharing many external resource around it and thus has a simple, flexible and low priced structure. However, A RSA has some problems in a system, which must guarantee a real-time condition, because it is designed to use network protocol JINI. For an example, a time delay occurs in transferring data from a vision service to a robot control service. In this paper, we propose a data accessing service (DAS) to solve this problem. It is a service of a network protocol, JINI, which transfers data between two services. Its basic function is to find a data source service that a data destination service needs, and after doing this, a DAS transfers data between two services using not JINI, but another network protocol such as TCP/IP or UDP. As a result, we reduced a time delay to access data. Some experimental results show validity of our proposition.
