PerceptTwin: Semantic Scene Reconstruction for Iterative LLM Planning and Verification

ICRA 2026poster

Simulation environments are useful for both robot policy learning and planning verification and validation. Traditionally, the process of creating a simulation was onerous. Creating a bespoke simulation environment for each individual environment that a robot would operate in was simply infeasible. …

Perpetua: Multi-Hypothesis Persistence Modeling for Semi-Static Environments

IROS 2025

Many robotic systems require extended deployments in complex, dynamic environments. In such deployments, parts of the environment may change between subsequent robot observations. Most robotic mapping or environment modeling algorithms are incapable of representing dynamic features in a way that ena

Safety Representations for Safer Policy Learning

ICLR 2025poster

Reinforcement learning algorithms typically necessitate extensive exploration of the state space to find optimal policies. However, in safety-critical applications, the risks associated with such exploration can lead to catastrophic consequences. Existing safe exploration methods attempt to mitigate…
