OpenAI is releasing an open-source Python library for simulating robots. The library uses the MuJoCo engine and was developed during their past year of robotics research. It's designed to run physics simulations quickly, which can be useful for training AI models that control robots. --- Why it matters: This matters because it provides researchers with a high-performance tool for testing and training robot control algorithms in a simulated environment, without the need for expensive hardware.
