Overview

  • Link-bots are chain-like robots made of self-propelled particles that achieve complex, coordinated behaviors without sensors, AI, or centralized control.
  • Inspired by collective behaviors in nature, these robots perform tasks like navigating tight spaces, transporting objects, and collaborating on complex actions.
  • The research team developed computational models to explore how link configurations and particle counts influence movement and task performance.
  • Unlike traditional swarm robots, link-bots operate with minimal technology, making them low-cost and energy-efficient for challenging environments.
  • Potential applications include disaster response, rough-terrain logistics, and environmental monitoring, showcasing their versatility and real-world relevance.
