From Tom Thumb to the Dockers: Some Experiments with Foraging Robots

In this paper, we experiment, from the point of view of their efficiency, different implementations of the explorer robots application. Three types of Tom Thumb robots, whose behavior is based on the foraging behaviors of ants are proposed and their results are critically examined. We then introduce chain-making robots (the dockers), governed by local perceptions and interactions. This helps us to show that only a few changes in the robots' behavior may greatly improve the efficiency of the population.
