Magnetic microrobots have been developed to accomplish complex tasks via collective behaviors. However, inter-robot communication in magnetic system relies only on magnetic attraction, which is vulnerable to external stress from rough terrains or environmental obstacles which result in disassembly of microrobots. Here, we present magnetic Linkbots which can autonomously form physical interlocking during in-situ magnetic rotating actuations. Through physical interlocking, the Linkbots achieve higher aspect ratios and stronger inter-robot assembly forces than magnetically assembled robots. As a result, the microrobots are capable of obstacle climbing and bridging disconnected pathways. This physical interlocking strategy provides a new paradigm for constructing highly reliable magnetic robotic systems.
