LEARNED DEXTERITY

A goal. A grasp.
A thousand tiny adjustments.

Drag the translucent target cube, or focus it and use the arrow keys. The solid cube in the hand is the physical object. Drag the background to orbit; scroll or pinch to zoom.

Wuji Technology’s released Hand 1 goal-conditioned PPO actor controls 20 finger joints through live MuJoCo contact physics. Physics and inference run locally on your device. This is the original policy, with no retraining or distillation.
