The robot positioning plays a vital role in the motion control system and task execution aspects, a robotic precision positioning system based on wireless sensor networks is designed to improve the positioning accuracy of the robot operating in a particular environment. The Receive Signal Strength Indication (RSSI) is used to rang and locate by Chip NanoPAN5375 on the on the microprocessor hardware platform ATmega1280, and the positioning accuracy is improved using dual ranging bilateral symmetry and maximum likelihood estimation algorithm. Meanwhile, the Multi-robot collaboration positioning is solved by based polling division multiple access protocol and table-driven cluster routing protocol, which makes the system to get a balance on the network performance. Through experiments in the 60m × 60m area show that the system is stable and reliable measure of the relative positioning error is less than 0.25m, with high accuracy, which is suitable for mine rescue robot positioning needs nuclear leak detection and volcanic exploration and other special circumstances.
