Researchers build next-gen swarm robots that move and cooperate without code or sensors

Researchers from Harvard and Seoul National University have developed "link-bots," swarm robots that operate without sensors, AI, or complex controls. These self-propelled particles connected in flexible chains rely on simple physics to move and cooperate. By adjusting link geometry, the robots can navigate tight spaces, form barriers, and transport objects. This nature-inspired approach offers potential for low-cost, adaptable robotic systems that could function in unpredictable environments.
