OpenAI has released eight simulated robotics environments and an implementation of Hindsight Experience Replay (HER) to advance robotics research. These new environments, built for the MuJoCo physics simulator, feature more complex manipulation tasks than previous benchmarks and utilize sparse rewards to mimic real-world robotics applications. The HER algorithm, also released, enables reinforcement learning agents to learn from failures by treating achieved states as goals, even if they weren't the original target. AI
