Choosing a Charging Station Using Sound in Colony Robotics

This research is part of a study that is investigating methods for supplying power to autonomous robots in remote locations. One possibility is to provide autonomous charging stations fueled through solar power. This paper reports preliminary results for a system being proposed to help a robot determine which station, among those available, would be its best source of power. The system uses distinct sound frequency bands to determine the available stations and uses the characteristics of sound and the environment as a type of analog computer to help compute, considering each station´s distance and available energy, the best station to track towards.
