| Abstract: | To overcome the drawbacks of the conventional artificial potential fields in motion planning of mobile robots for dynamic uncertain environments,an artificial coordinating field (ACF) is proposed.Definitions and basic designs of the ACFs were investigated with regard to the collision risk and motion constraints of mobile robots.Based on the ACFs,an effective algorithm without the "dead-lock" for coordinating collision avoidance of multiple mobile robots in dynamic uncertain environments was developed.The theorical analysis and simulations illustrated our results. |

| Keywords: | artificial coordinating fields dynamic uncertain environments coordinating collision avoidance multiple mobile robots |
