—Developing open mobile robot has been a hot topic in AI area. In an open system, a particular component can be easily added and/or replaced. In this paper, a modular and object oriented approach is used to construct an autonomous mobile robot system. IPC (interprocess communication), which is the key mechanism in Linux/Unix operation system, is applied to(More)
