About MuJoCo

MuJoCo, short for Multi-Joint dynamics with Contact, simulates the physics of robots and objects quickly and accurately. It has become a standard for research in robot control and reinforcement learning. Google DeepMind maintains it as open source, and extensions like MJX run simulations on GPUs for very large-scale training. It has Python bindings and works with many learning frameworks. MuJoCo is free to use. It is a core tool for anyone training robot policies in simulation.
