Multi-robot systems have been widely used in various actual fields to perform specific tasks. In the robot system, path planning is a burning problem. To solve this challenging issue, we mainly study the problem of path planning between robots and robots, robots and robots systems. Three factors are taken into account in the paper: the robot autonomous model, the real-time detection of speed and the obstacle risk. And we find that the robot's motion path ultimately depends on a technique based on hierarchical fuzzy control. From the simulation results, we get the conclusion: in the multi-robot system, obstacle avoidance and path decision made by the hierarchical fuzzy control system are both effective and practical.
