Wang Letian, VP of Product at Robot Era: From "Dexterity" to "Intelligence," the "Hand-Brain" Co-Evolution Logic Behind XHand

Wang Letian, VP of Product at Robot Era, explains the "software-defined hardware" design logic of its XHand dexterous hand: the fully direct-drive architecture serves reinforcement learning, imitation learning, and mass-production consistency; backdrivability supports teleoperation data collection and Sim2Real transfer; and it has been used as a foundational platform in more than 20 top-conference papers worldwide. The hand has cumulative sales of over 1,000 units and weighs 880 grams; last year it reached annual production on the scale of a thousand units, a single logistics order reached 50 million, and it secured its latest funding round led by SF Express.
