newsResearchers developed HALyPO (Heterogeneous-Agent Lyapunov Policy Optimization), a new approach to improve stability in human-robot collaboration through multi-agent reinforcement learning. The method addresses the 'rationality gap' between human and robot learning by using Lyapunov stability conditions to prevent policy oscillations and divergence during training.
Researchers developed a new three-layer hierarchy called cognition-to-control (C2C) for human-robot collaboration that combines vision-language models with multi-agent reinforcement learning. The system enables sustained deliberation and planning while maintaining real-time control for collaborative manipulation tasks between humans and humanoid robots.
Researchers propose UrbanHuRo, a two-layer human-robot collaboration framework that jointly optimizes different urban services like delivery and sensing. The system demonstrated 29.7% improvement in sensing coverage and 39.2% increase in courier income while reducing overdue orders through coordinated optimization of heterogeneous services.
