About this paper

This research from institutions including Sorbonne Université and the University of Wyoming developed an Intelligent Trial and Error (IT&E) algorithm, enabling robots to rapidly adapt to unforeseen damage in minutes. The approach combines offline simulation for diverse behavior mapping with online Bayesian optimization, allowing physical robots to discover new functional behaviors with few trials.
Key insights
- Combining extensive offline exploration (MAP-Elites) with efficient online learning (Bayesian optimization initialized with the map) overcomes the 'curse of dimensionality' for rapid physical robot adaptation.
- Robots can adapt to unforeseen damage without explicit self-diagnosis by learning from observed performance drops and intelligently searching their behavior space.
- A diverse archive of pre-computed behaviors serves as a crucial 'intuition' that significantly speeds up online adaptation and enables the discovery of creative solutions.
