Intelligent robotic systems-from a single robot to multiple robotic system

There have been a lot of works on the improvement of the robotic performance. Nowadays a robot can work well under given constraints and environments. But the performance of a single robot might be limited and some needs more complex performance. To cope with the complex works, there are several approaches, such as more sophistication of a single robot and multiple robotics with different levels of capacities. In this paper, the multiple robotic system approach will show more flexibility and adaptability to various tasks and environments. The robots with different capacities, such as Cellular Robotic System (CEBOT), are one of the distributed autonomous robotic systems and consist of the heterogeneous system, thus can create intelligence for wider tasks. This paper describes these characteristics of the robotic system depending on the level
