Efficient Multi-RobotLocalization Based on Monte Carlo Approximation

Proc. of the 9th International Symposium ofRobotics Research (ISRR-99), 1999



Abstract

This paper presents a probabilistic algorithm for collaborative mobilerobot localization. Our approach uses a sample-based version of Markovlocalization, capable of localizing mobile robots in an any-time fashion.When teams of robots localize themselves in the same environment, probabilisticmethods are employed to synchronize each robot's belief whenever one robot detects another. As a result, the robots localize themselves faster, maintainhigher accuracy, and high-cost sensors are amortized across multiple robotplatforms. The paper also describes experimental results obtained usingtwo mobile robots, using computer vision and laser range-finding for detectingeach other and estimating each other's relative location. The results, obtainedin an indoor office environment, illustrate drastic improvements in localizationspeed and accuracy when compared to conventional single-robot localization.
