Where you race the code.
Put physical intelligence to the test. Write a controller, climb a global board, and let real physics decide the winner.
Forge
Describe a physical thing in plain words, or pick one from a curated image gallery. We build it instantly and you drive it, while an on-device model authors a custom version on your GPU. Pick an image and on-device depth turns it into a 3D object with real physics you can knock around. No cloud, no camera.
Play now →NewPilot
Take the controls of an embodied AI. Drive a real MuJoCo rover with your PlayStation, Xbox, or Switch controller (or the keyboard), see the world as it does, and hand the wheel to its policy.
Play now →NewFPV Drone
Fly a real-physics quadrotor in first person. Throttle, yaw, pitch, and roll on any controller, with a nose camera and a chase view. Weave the pillars and rings.
Play now →NewRobot Arm
Pilot a fixed-base manipulator to pick up a block and place it on a target. Fly the gripper in straight Cartesian lines through the Jacobian, close the fingers, and watch the world through a wrist camera.
Play now →NewUnderwater AUV
Pilot a free 6-DOF submarine through a coral reef. Near-neutral buoyancy gives it a floaty, momentum-heavy glide. Thrust, yaw, pitch, and dive on any controller, with a nose camera and a chase view, and collect the glowing markers.
Play now →NewQuadruped
Walk a legged robot dog, the iconic Physical AI form. An open-loop central-pattern-generator turns your stick into a stable diagonal trot in real MuJoCo physics. Steer, turn, and watch the world it maps through its rangefinder.
Play now →NewHumanoid
Pilot a two-legged robot to walk. Bipedal balance is the hardest problem in Physical AI, so the work is shared: the AI holds the balance, you steer the direction. A stabilized, statically-stable gait keeps it upright in real MuJoCo physics while your stick sets the pace.
Play now →Live nowLeaderboards
Every embodiment's global board on one wall. The fastest rover, drone, arm, AUV, quadruped, and humanoid run worldwide, each verified by real physics.
Play now →Live nowThe Arena
Write a controller for a real MuJoCo rover and race a daily course of checkpoint gates against a worldwide board.
Play now →Live nowLeagues & Seasons
Race the daily Arena challenge and score points by rank. Points build a season standing that sorts you into Bronze, Silver, or Gold.
Play now →Live nowRobot Sports
Two rovers, one ring. Sumo: write a controller and push the house bot off the platform, best of three, in real contact physics.
Play now →Live nowThe Sandbox
Build a course in a top-down editor, race it with a real rover, and publish a link so the world can try to beat your time.
