Isaac Lab-Arena policy regression testing: build a versioned evaluation gate
Turn Isaac Lab-Arena Experiments, controlled variations and task metrics into a versioned policy regression gate without overstating simulation evidence.
World Models and Simulation
English articles about world models and simulation at Physical AI Lab.
Drake hydroelastic or point contact? Check the geometry pair first
Drake can fall back to point contact even when a simulation runs. Check geometry representations, supported pairs and a version-specific documentation discrepancy.
