A Million Simulators Learned More by Ignoring Easy Resets
Success Guided Sampling concentrates robot training near the frontier between mastered and not-yet-reachable task configurations.
Summary
Success Guided Sampling concentrates robot training near the frontier between mastered and not-yet-reachable task configurations.
Uniformly sampling simulator resets wastes training on situations a robot has already mastered or cannot yet attempt. Success Guided Sampling adapts the reset distribution toward configurations around the policy’s current capability frontier. In experiments scaling to more than one million parallel environments, that change let reinforcement learning solve multi-terrain locomotion and contact-rich assembly tasks that the tested prior methods did not solve. The authors then distilled manipulation policies into RGB-based controllers and report zero-shot transfer to real hardware. The paper’s claim is about using each simulated batch more effectively; it does not show that raw simulator count alone produces general-purpose robot control.
