Swarm robotics can be defined as the study of how a swarm of relatively simple
physically embodied agents can be constructed to collectively accomplish tasks
that are beyond the capabilities of a single one. Different from other studies on
multi-robot systems, swarm robotics emphasizes self-organization and emergence
while keeping in mind the issues of scalability and robustness. These emphases
promote the use of relatively simple robots, equipped with localized sensing abilities,
scalable communication mechanisms and the exploration of decentralized
control strategies.
