Online automatic code generation for robot swarms: LLMs and self-organizing hierarchy

This abstract was accepted to and presented at the "Multi-Agent Cooperative Systems and Swarm Robotics in the Era of Generative AI" (MACRAI) workshop at the 2025 IEEE/RSJ Int. Abstract--Our recently introduced self-organizing nervous system (SoNS) provides robot swarms with 1) ease of behavior design and 2) global estimation of the swarm configuration and its collective environment, facilitating the implementation of online automatic code generation for robot swarms. In a demonstration with 6 real robots and simulation trials with >30 robots, we show that when a SoNS-enhanced robot swarm gets stuck, it can automatically solicit and run code generated by an external LLM on the fly, completing its mission with an 85% success rate. Swarm robotics research has demonstrated that many sophisticated behaviors with a large number of robots can be accomplished in a fully self-organized manner [1], but these fully self-organized behaviors have been slow to transfer to real applications. One reason for this is the fact that robots in a swarm are programmed at the individual level but the desired behavior occurs at the group level, and the design of fully self-organized group behaviors is often analytically intractable [2], [3], requiring extensive trial-and-error testing.
