Hilbert-augmented RL paper validates multi-robot coverage trajectories on Spot

Evidence notes
- The paper augments DQN and PPO with Hilbert space-filling priors for decentralized coverage and exploration.
- The approach is validated on a Boston Dynamics Spot legged robot executing generated trajectories in indoor environments.
Company context
Boston Dynamics builds high-performance mobile robots including Spot for industrial and field inspection, Stretch for warehouse trailer unloading, and Atlas for advanced humanoid mobility.
