RoboBridge: A Self-Evolving Embodied Agent Framework for Sim-to-Real Transfer
Preprint. RoboBridge is a framework that represents manipulation tasks as editable procedural skills and wraps a frozen vision-language-action policy as a guided action tool, evolving those skills from execution feedback. On LIBERO-PRO it reaches 74.4% overall success, beating the strongest reported baseline at 72.1%; on three real-robot tasks, 10 episodes of adaptation lift success from 9/15, 7/15, 7/15 to 15/15, 14/15, 15/15. This shifts sim-to-real transfer from retraining to selective skill revision, cutting adaptation iterations by 25% and token use by about 75%.
