1X Releases Engineering Details of NEO's Humanoid Hand
rohanpaul_ai · x · 2026-07-11
An introduction to 1X's next-generation humanoid hand design for NEO, focusing on the ability to "feel contact like a human" rather than just moving.
Key Design
- Employs a low-reduction-ratio tendon drive, allowing external forces to be transmitted back across joints, reducing finger weight and minimizing collision impact.
- Motors are housed in the forearm, driving the fingers via tendons routed through the wrist, mimicking biological muscles.
- Features 22 active degrees of freedom in the fingers/palm and an additional 3 in the wrist, with the thumb carrying a heavier weight for flexibility.
Perception and Control
- Equipped with closed-loop proprioception, acquiring posture and force feedback without relying on cameras.
- Tactile skin can sense contact, pressure, and shear forces, enabling rapid grip adjustments when objects slip.
Reliability Focus
- Emphasizes a true opposable thumb, lightweight fingers, and high grasping control capabilities.
- Also notes that the hand features an IP68 sealing rating and design considerations related to food safety.
