These Might Be the Best Robot Hands Ever Built

The 1X NEO robot introduces a sophisticated hand design featuring 22 degrees of freedom (DoF) to handle intricate manipulation. These hands are IP68 waterproof, meaning they are submersible, and they have been designed to be food-safe—allowing the robot to wash its own hands. This development represents a significant step in the physical AI landscape, particularly for consumer robotics targeting household chores.Tendon-Driven ActuationInstead of using rigid gearboxes or heavy harmonic drives common in other humanoids, NEO employs a proprietary tendon-drive system. This biomimetic approach uses high-torque-density electric motors that pull flexible polymer tendons, similar to human muscles. This architecture provides fluid motion and precise control while keeping the robot extremely quiet, operating at just 22 decibels.Design and Safety ProfileThe NEO robot stands 5’6” tall but weighs only 66 pounds. It has a soft, custom 3D-lattice polymer body and is clothed in a machine-washable knit suit, which acts as a protective layer and makes the robot safe and approachable for domestic use. The tendon-driven design, combined with the lightweight structure and pinch-proof joints, is intended to minimize the risk of injury if the robot falls.Capabilities and ManufacturingDespite its light frame, NEO can lift up to 154 pounds and carry 55 pounds. Its 22-DoF hands have a grip strength capable of deadlifting 70kg, and the hands are naturally compliant to withstand falls. 1X manufactures the hands, actuators, and polymer molding in-house at their facility in Hayward, California. The robot is powered by an NVIDIA Jetson Thor chipset and operates for up to 4 hours per charge.“The Hand Problem”The development of highly capable robotic hands, often referred to as “the hands problem” or “Moravec’s Paradox,” is widely considered the most difficult hardware challenge in humanoid robotics. While robots are proficient at balancing, walking, and heavy lifting, replicating the dexterity required for unstructured, everyday human tasks like handling fragile items or cracking eggs remains a massive bottleneck.The difficulty in building humanoid hands stems from compounding factors of complexity, space, and reliability. Human hands have over 20 degrees of freedom, which requires engineers to pack dozens of miniaturized actuators, custom motors, and control systems into a very tight volume. Fully-actuated hands (with a motor for every joint) are extremely heavy, while under-actuated hands (using fewer motors with mechanical coupling) sacrifice precision.Why the Hands are So SignificantThe hands on 1X’s NEO robot are one of its key differentiators, designed to mimic human dexterity while being robust enough for household tasks. They represent a shift toward prioritizing active control and durability in consumer-ready physical AI.Additional Resources for Inquisitive Minds:WIRED. The 1X Neo Robot Has Freaky Fast Fingers.
