This research develops a framework for robots to build complete semantic maps in cluttered environments by intelligently combining passive observation with active manipulation actions. It introduces Calibrated Neural-Accelerated Belief Updates (CNABUs) within a POMDP framework, enabling a UR5 robot to identify 39% more previously unseen objects in real-world cluttered shelf scenes compared to non-interactive baselines.
Key insights
- Integrating manipulation and observation actions within a unified POMDP framework, rather than relying on heuristic switching, allows for more intelligent and efficient information gathering in cluttered environments.
- Learned map-space belief dynamics (CNABUs) with calibrated uncertainty are crucial for robust decision-making in high-dimensional, interactive environments, addressing the computational challenges of traditional POMDPs.
- Explicit 3D map representations combined with learned belief dynamics offer interpretability, long-term consistency, and robustness to out-of-distribution object shapes, facilitating zero-shot transfer to real robots.
