https://playground.mujoco.org/ MuJoCo Playground We introduce MuJoCo Playground, a fully open-source framework for robot learning built with MJX, with the express goal of streamlining simulation, training, and sim-to-real transfer onto robots. With a simple installation process (pip install playground), researchers can train policies in minutes on a single GPU. Playground supports diverse robotic platforms, including quadrupeds, humanoids, dexterous hands, and robotic arms, and enables zero-shot sim-to-real transfer from both state and pixel inputs. This is achieved through an integrated stack comprising a physics engine, batch renderer, and training environments. MuJoCo Playground was a community effort involving multiple groups, and we hope it proves valuable to researchers and developers alike. paper code live demo starter locomotion manipulation vision Teaser Quadruped Locomotion Joystick Handstand Footstand Fall recovery Sim2Sim Transfer Humanoid Locomotion Manipulation In-Hand Reorientation Sim2Sim In-Hand Reorientation In-Hand Z-Axis Rotation Vision-based Grasping ALOHA Peg Insertion Non-Prehensile Manipulation All videos on this page are shown at 1x speed (real-time).
