Hard hardware problems are not solved by better first drafts. They are solved by shortening the distance between build and break. Build the iteration engine first.
I see you @Ritwikdau 👀
Appreciate the appreciation. We are obsessed with making the best hands and we have just begun the journey.

Ungloved, the new 1X hand looks beautiful.
25 DoF, tendon-driven, force-controlled, tactile sensing, IP68 sealed, ±0.2mm positioning accuracy.
1X has already described NEO as being built in America’s most vertically integrated humanoid robot factory, and that strategy shows up here too; every hand is built end-to-end in-house, from tendon materials and 1X Motors to soft polymers, skin and tactile sensing.
They have stated hundreds have already come off the line, with capacity for 10,000 hands this year.

A stunning piece of engineering!!
1X unveils the new humanoid hand for NEO
- 25 degrees of freedom: 22 fully actuated in the fingers and palm, plus 3 at the wrist.
- The DoF are distributed anatomically rather than evenly, deliberately biased toward a thumb that genuinely opposes the fingers.
- In-house tendon-driven, quasi-direct-drive running low gear ratios of ~5:1 to 15:1 vs the typical 100:1–200:1.
- Motors live in the forearm and pull tendons through the wrist. This keeps the hand light and its inertia low while producing high forces.
Sensing
- All 25 DoF are natively force-controlled and fully backdrivable. Every joint doubles as a force sensor.
- Very important, closed-loop proprioception: it always knows its own pose and effort without looking.
- Tactile skin across the fingertips and surfaces measuring contact and shear. This helps with adaptive gripping in real time.
Safety and durability
- IP68 waterproof and food-safe, so it can wash its own hands.
- Compliant by construction: the low gear ratios, tendon drive, and low distal inertia let external impacts safely backdrive the fingers. It yields when hit by a hammer or caught in a drawer.
- Full finger assemblies validated to millions of cycles.
Manufacturing
- Deep vertical integration: in-house motors, custom electronics, and tendon systems.
- Hundreds built already, with capacity to produce 10,000 hands this year.

U.S. based humanoid robotics company @1x_tech has just unveiled their new tendon-driven robot hands with 25 degrees of freedom (DOF).
• Made in USA
• Tendon Drive Ratio: 5:1–15:1
• Wrist Dexterity: 3 DOF
• Backdrivability: Fully backdrivable
• Tactile Sensing: Pressure + location + slip
• Finger Force: Up to 45 N
• Wrist Torque: 17.75 Nm
• Position Accuracy: ±0.2 mm
• Waterproof Rating: IP68
• Reliability: >2 million cycles
"These hands are designed to do something fundamental: remove the hardware ceiling on what humanoid robots can actually do, and make data the only barrier to capabilities. By matching or surpassing human hands across the dimensions that matter, they ensure our AI models are no longer limited by dexterity. NEO can now perform virtually any task a human can do with their hands– with the precision, adaptability, and gentleness required for real-world environments."
