Distributed Range-based Localization for Swarm Robot Systems using Sensor-fusion Technique

摘要

Herein, we present a localization method for swarm robot systems that relies solely on measured distances from surrounding robots. Using the sensor fusion technique, an exteroceptive estimation method based on the measured distance is dynamically coupled with a simple proprioceptive estimation that uses a robot’s own dynamical properties. Our method strictly preserves the locality of algorithm. The results of numerical simulations for several scenarios show that our proposed method is more accurate that conventional methods.
