Abstract An adaptive power control system for RFID which is applying for mobile robot localization was proposed. The Mahalanobis distance is introduced to particle filter as an evaluation function for particle weight to avoid particle depletion. Meanwhile, an evaluation function for the performance of localization using particle filter was proposed and used to adapt antenna power to the distribution character of tags in a local environment. The experiments show that the proposed method obtains higher and more consistent localization accuracy as well as systems reduced power consumption.
