New RAPT model enhances humanoid robot safety in sim-to-real transfers

By PulseAugur Editorial · [1 sources] ·

Researchers have developed RAPT (Recurrent Anomaly Probabilistic Trajectory Model), a new system designed for detecting out-of-distribution states and diagnosing failures in humanoid robots during sim-to-real deployment. This lightweight, self-supervised model operates at 50 Hz and learns nominal robot behavior from simulation data to predict deviations in real-world execution. RAPT aims to provide calibrated, per-dimension predictive-deviation signals, enabling detection under strict false-positive constraints and localizing when and where execution diverges from nominal behavior. For post-hoc diagnosis, RAPT integrates temporal saliency, joint-kinematic summaries, and LLM-based semantic reasoning to classify failure causes in a zero-shot manner. AI

IMPACT Enhances safety and reliability for humanoid robots transitioning from simulation to real-world deployment.

    RAPT: Model-Predictive Out-of-Distribution Detection and Failure Diagnosis for Sim-to-Real Humanoid Deployment

    arXiv:2602.01515v2 Announce Type: replace-cross Abstract: Deploying learned control policies is risky because policies that appear robust in simulation can confidently enter out-of-distribution (OOD) states after Sim-to-Real transfer, causing silent failures and potential hardwar…
