Multi-robot Task Planning Method Study

Multi-robots task planning works in the multiple robots system. It assigns several tasks to the robots in the system, makes them complete the tasks without collision. Now, robot can not complete the complex task lonely any more. So, the study of multi-robots has been focused on more and more. Good planning of multi-robots is important to improve the effect of robots'work. This paper will study path planning method in multi -robots system. On the sample of a simulation model of robots move goods in automatic warehouse.Firstly, this paper introduce the development and characteristic of the multi -robots system. Then introduce the task planning and path planning methods of multi-robots, emphasicing on some path planning methods, which are the focus of researchers. After this, we take an example for a simulation model of robots moving goods in the automatic wearhouse and explain a path planning method based on collosion check, which can plan path of multi-robot efficially and react to the changed environment. Subsequently, we explain another path planning method called artificial potential method based on priority. This method comes out the multiple potential according to each robots. Finally, we carry out an simulation using the DC class of VC to prove the theory of the two method, the result shows the latter is better than the former. Based on the short of the latter prospects the research work in the future.
