Collective search of a single odour source using cooperation

We study coordination strategies for a multirobot team. The goal is to find the source of an odour most efficiently in terms of the distance travelled by the robots and the time required to discover the source. We focus on the problem of finding the source of the odour once a robot has already found the plume of this odour. The results show that the studied algorithms are effective in non-homogeneous wind models, which include turbulences.
