1X Technologies has unveiled breakthrough hands for its Neo humanoid robot that achieve near-human-level dexterity, strength, and tactile sensitivity, removing a major hardware barrier that has long prevented robots from handling everyday household tasks. The new hands feature 25 degrees of freedom (DOF), tendon-driven mechanics, and built-in force sensing that allows Neo to manipulate fragile objects, detect slip, and adjust grip pressure in real time.

What Makes These Robot Hands Different From Previous Designs?

The fundamental difference lies in how these hands sense and respond to their environment. Traditional industrial robot hands rely on high gear ratios that prioritize raw strength but eliminate the ability to detect physical contact. Once a robotic finger reaches its target position, the system receives almost no feedback about what it is touching or how much force it is applying.

Neo's new hands flip this approach. They use tendon-driven mechanics with significantly lower gear ratios, roughly between 5:1 and 15:1, compared to the much higher ratios found in conventional robotics. This "force transparency" allows contact forces to pass back through the transmission, enabling the robot to measure how hard an object is pushing against its fingers without relying solely on external sensors. Each of the 25 actuated joints can both generate movement and measure external forces, functioning as both a motor and a sensor simultaneously.

High-resolution tactile sensors embedded throughout the fingertips and hand surfaces detect pressure, contact location, and shear forces. This continuous stream of sensory information allows Neo to adjust its grip in real time rather than simply following pre-programmed movements.

What Tasks Can Neo Actually Perform With These Hands?

The demonstrations of Neo's capabilities reveal the breadth of what becomes possible when a robot hand achieves human-like dexterity. According to 1X, Neo can now perform a wide range of fine and complex manipulation tasks:

• Delicate Assembly: Assemble LEGO structures, pick up individual screws and coins from a wallet, and rotate objects in-hand with precision
• Household Maintenance: Spin and install light bulbs, use a screwdriver, zip a jacket, wipe surfaces with a paper towel and spray, and plug in a USB-C charger
• Food and Beverage Handling: Pour tea from a kettle, sort grapes by color, grab a wine glass, and handle other delicate kitchen tasks
• Adaptive Interaction: Catch a squishy ball, communicate via sign language, and perform countless other tasks requiring sensitivity and adaptability

The hands combine precision with substantial strength. The thumb can generate peak torque of 3.5 Newton-meters, while finger joints reach up to 2.6 Newton-meters and fingertip flexion forces up to 45 newtons. The wrist produces 17.75 Newton-meters of torque, supporting tool use, lifting, pushing carts, and opening doors. Positioning accuracy is rated at plus or minus 0.2 millimeters, allowing manipulation of small objects common in household and industrial environments.

How Do These Hands Enable Safer, More Practical Home Robots?

Beyond raw capability, the design prioritizes safety and practicality for home environments. The hands carry an IP68 waterproof rating, meaning they are sealed against dust and water and can be safely immersed. In practical terms, this allows Neo to wash its own hands after completing messy tasks, a feature rarely seen in humanoid robots. The hands are constructed from food-safe materials, making them suitable for food preparation and kitchen work without contamination concerns.

The low-inertia tendon-driven design also improves safety by allowing fingers to yield under unexpected impacts rather than remaining rigid. This backdrivable design means the robot can naturally give way when pressure is applied, reducing the risk of injury during interaction with humans or fragile objects.

"With these hands, NEO crosses a critical threshold. The robot can now do the things humans do with their hands, every day. This is what the industry has been waiting for," said Bernt Børnich, CEO and Founder of 1X.

How to Understand the Technical Architecture Behind Neo's Hands

• Tendon-Driven System: The hands use approximately 22 tendons paired into roughly 11 actuators, with square-profile wires inside Bowden tubes (bicycle-cable style sheaths) for better compression resistance than round wires
• Active Antagonism: Both flexion and extension are powered, allowing the robot to actively control movement in both directions rather than relying on passive springs
• Integrated Sensing: All 25 degrees of freedom can measure external forces, with high-resolution tactile sensors providing continuous feedback about contact, pressure, and slip detection
• Durability Testing: Components and finger assemblies have been tested through millions of operating cycles, with wrist joints validated beyond two million cycles under heavy loads

1X has designed these hands to be manufactured entirely in-house, with production already underway on a dedicated manufacturing line. The company stated it is capable of producing up to 10,000 hands this year. By manufacturing motors, tendons, electronics, tactile sensors, and soft polymer skins internally, 1X aims to accelerate the development of humanoid robots through large-scale deployment and continuous data collection for embodied AI systems.

The timing of this announcement is significant because 1X recently began mass-producing its Neo humanoid robot at a new California factory, advancing the commercialization of home robots designed to assist with daily household tasks safely. The company argues that while a humanoid's legs allow it to move through a home and its torso houses batteries and computing hardware, the hands ultimately determine how useful the robot becomes in everyday life.

1X also believes the hardware is currently more capable than the artificial intelligence driving it. That could prove advantageous in the long run. As Neo's AI improves through software and over-the-air updates, the robot may unlock new skills without requiring changes to its physical design. This means the breakthrough in hand dexterity removes what 1X calls "the hardware ceiling" on what humanoid robots can actually do, making data and AI training the only remaining barrier to capabilities.

The announcement highlights the growing competition in humanoid robotics, with several startups racing to build increasingly capable robotic hands. The recognition that dexterity remains one of the biggest obstacles to creating useful general-purpose robots has driven innovation across the industry. If Neo's hands perform as advertised, the vision of a robot that can prepare dinner, clean the kitchen, and safely handle everyday household objects may no longer seem as distant as it once did.
