Exploiting Embodiment in Multi-Robot Teams

摘要

This paper describes multi-robot experiments and systems which exploit their embodied nature to reduce needs for sensory, effector, and computational resources. Many natural phenomena, such as territorial markings or ant pheromone trails, take great advantage of the ability mark the environment, and of the natural dissipative processes which cause these markings to decay. In this way, globally complex behavior can result from simple local rules. The information invariants ([Donald 1995], [Donald et al 1994]) literature raises the issue of robots similarly recording information, or even "programs," into the physical environment. This paper provides example systems that dynamically encode information and "programs" into the physical environment, and by so doing, increase their own robustness and reduce their resource requirements and computational complexity. The main experimental system that we present, a robot "chain" used for foraging, is modeled after the natural phenomenon of ant ph...
