- Abstract:
-
Because multi-robot active SLAM cannot fully traverse an environment, and the localization accuracy is not ideal in an unknown environment, a new multi-robot active SLAM algorithm is proposed in this paper. By introducing attractors to enhance communication between multi-robot systems, the accuracy of robot localization and mapping is enhanced, and multi-robot teams are guided to explore the environment. When the same landmark is observed by multiple robots, convex combination fusion is used to fuse the estimate of the landmark by each robot, thereby reducing the uncertainty of the landmark. The simulation results show that the proposed algorithm can cover and traverse the environment and improve the localization accuracy of landmark estimation.
