Abstract: 　To overcome particle impoverishment, a simultaneous localization and mapping (SLAM) method based on multi-agent particle swarm optimized particle filter (MAPSOPF) was presented by introducing the idea of multi-agent to the particle swarm optimized particle filter (PSOPF) which is an algorithm for SLAM. In MAPSOPF, agents can communicate and compete with each other and learn from each other. The MAPSOPF algorithm can update the prediction of particle, adjust the proposal distribution of particles, improve localization precision and fault tolerance, and propel the particles to concentrate on the robot's true pose. Compared with standard particle filter (PF), the proposed method can achieve better SLAM precision by fewer particles. Simulations verify its effectiveness and feasibility.
