The ability of robots to quickly and accurately localize their neighbors is extremely important for robotic teams. In this video you will see our trilateration approach to multi-robot localization, which is fully distributed, inexpensive, scalable, and robust. We are testing the ability of trilateration to work in real-world outdoor conditions, at a quite reasonable rate of speed.
With our approach there is no global controller what-so-ever. This means there are no hidden beacons, GPS units, over-head cameras, etc. There is no pre-programmed environmental knowledge. There is no central CPU. The system is fully distributed and all computations are done on a mere 24Kb of RAM per robot. We hope you will enjoy our "swarm death metal" music background.
