Reconfigurable Microrobotic Collectives Illuminate Future Medicine and Environmental Remediation

Abstract Mobile microrobots can navigate, sense the environment, and interact with it, potentially revolutionizing biomedicine and environmental remediation. Many self-organizing microrobotic collectives have been developed to overcome the inherent limitations of actuation, sensing, and manipulation of individual microrobots; however, reconfigurable collectives with robust transitions between behaviors are rare. Such multifunctional systems are advantageous for operation … Read more
