Research Paper
Core Innovation
This paper introduces ODiSAR, a Transformer-based digital twin approach that forecasts robot states and quantifies uncertainty using reconstruction error combined with Monte Carlo dropout. This dual metric enables robust detection of out-of-distribution behaviors in self-adaptive robots, even under previously unseen conditions. Additionally, the model includes an explainability layer that links detected anomalies to specific robot states, facilitating actionable insights for self-adaptation.

Research Paper Overview
Out of Distribution Detection in Self-adaptive Robots with AI-powered Digital Twins
Summary
Self-adaptive robots in complex environments need to detect abnormal behaviors including out-of-distribution cases. This paper presents ODiSAR, a digital twin-based approach using a Transformer model to forecast robot states and quantify uncertainty via reconstruction error and Monte Carlo dropout. Combining these metrics enables effective detection of OOD behaviors even in unseen conditions. An explainability layer links OOD events to specific robot states to support self-adaptation. ODiSAR was evaluated on digital twins of industrial robots in office navigation and maritime ship navigation, achieving up to 98% AUROC, 96% TNR@TPR95, and 95% F1-score while providing interpretable insights.
