Georgia Tech researchers developed swarms of simple robotic particles that coordinate and self-organize without electronics, software, or sensing, relying entirely on physical design and local interactions.
The work is notable because it pushes stigmergy-like coordination into hardware itself, suggesting a path to ultra-robust swarm systems for medicine or space where computation, communication, or power are constrained.
