Multi-robot searching with sparse binary cues and limited space perception

open access: yesFrontiers in Robotics and AI, 2015
In this paper, we consider the problem of searching for a source that releases particles in a turbulent medium with searchers having binary sensors and limited space perception.To this aim, we extend an information-theoric strategy to multiple searchers ...
