| Abstract: | Robot Simultaneous Localization and Mapping （SLAM） are two key issues in robot autonomous navigation. In recent years, with the development of robotics, the investigation of Multi-robot Simultaneous Localization and Mapping becomes the central areas of SLAM. To achieve Multi-robot SLAM, the Extended Information Filtering algorithm is applied to multi-robot system. Multi-robot motion models are established according to the robot motion structure and rigid body constraints, and observation models are constructed with the odometers and laser ranging sensors. Based on the results of theoretical analysis, the global map is utilized by SLAM to correct multi-robot pose in period of updating map. The Extended Information Filtering algorithm is used to solve the Multi-robot Simultaneous Localization and Mapping problems in the process. The simulation results are suggestive of the sufficiently good robotic positioning and performance robustness in the SLAM. |
