    Thoughts on high-DoF 5-finger hands I believe a perfect robot replica of the human hand could have complete overlap w/ the space of human potential However I think this undersells the potential of robotics & ignores the practicalities of early deployment and its benefits One

    Why create robot intelligence for just one hand, when we could have it learn from many? GEN-1, our latest embodied foundation model, now supports a broad range of end effectors from 5-finger hands, to specialized tools, and everything in between.

    This is an extremely common repetitive industrial task still done by humans. Most industrial screwdrivers are these driving-force-activated, torque-calibrated, powered systems. It's just consumers who think you need a trigger finger.

    What happens when you change the hand mid-task? We tested this by modifying the hands mid-rollout and letting the same model keep running. It perceives the new tool, and finds a new trajectory and contact strategy to complete the task. This works because training on mixed data

    If we can build general intelligence that understands the underlying physics of interaction, then the shape of the hand becomes secondary to the intelligence that drives it. A suction pad, a gripper, a brush, a plasma welding nozzle – are all just different interfaces through

    Thousands of kinds of cheap, task-specific hands are far more practical for today’s models than expensive, fragile, 20+ DoF 5-finger hands. This demonstrates you actually don’t sacrifice useful dexterity.
