Physics-verified manipulation

Every step predicts a number, then measures it

running in this tab

A robot arm that states what its sensors should read before it moves, then checks whether they did. A camera can be fooled by an arm in the way. A load cell cannot be talked into believing a grasp that never happened.

Type an instruction and watch it run. This is not a replay: MuJoCo compiled to WebAssembly, loading the same scene file the desktop stack uses, with the physics, the inverse kinematics, the load cells and every verification check executing in your tab. Recorded runs planned by a language model →

Drag to orbit, scroll to zoom. Load cells read contact-free baselines, so they show object mass rather than the arm leaning on the plate.
