1X Unveils Tendon-Driven Robotic Hand with 25 Degrees of Freedom for NEO Humanoid Robot
Humanoid robotics company 1X has introduced a new tendon-driven robotic hand designed for its NEO humanoid robot platform. Featuring 25 degrees of freedom — including 22 fully actuated joints — the hand delivers near-human dexterity, force output, and tactile sensing, while enabling more advanced AI-driven manipulation capabilities. No production timeline has yet been announced.
Highlights
- 1X has released a tendon-driven robotic hand with 25 degrees of freedom, including 22 fully actuated joints, designed for its NEO humanoid robot platform.
- The tendon-driven design mimics human hand biomechanics, enabling more compliant, natural motion and reducing the risk of object damage compared to rigid gear-driven systems.
- Integrated tactile sensing allows the NEO robot to perceive an object's shape, material, and applied force, supporting precision manipulation tasks.
- 1X states the high-DoF hand will provide richer sensory data to machine learning models, advancing AI-driven manipulation in home and industrial environments.
- No mass-production timeline or commercial roadmap for the new robotic hand has been announced by 1X as of publication.
Humanoid robotics company 1X has announced a new tendon-driven robotic hand designed exclusively for its NEO humanoid robot platform. According to the company, the hand is engineered to bring near-human levels of dexterity, force control, and tactile sensing to the NEO robot, while also laying the groundwork for more sophisticated AI-driven manipulation.
Key Specs: 25 Degrees of Freedom
The new hand features 25 degrees of freedom (DoF), of which 22 are fully actuated joints. This high degree of articulation allows the NEO robot to perform finer, more complex manipulation tasks, significantly closing the gap between robotic and human hand dexterity.
Advantages of Tendon-Driven Design
The tendon-driven architecture mimics the muscle-and-tendon transmission structure of the human hand. Compared with conventional rigid gear-driven systems, this approach produces more natural, compliant motion output and reduces the risk of damaging objects during handling. Combined with integrated tactile sensing technology, the NEO robot can more accurately perceive an object's shape, material properties, and the amount of force being applied — establishing a strong foundation for precision manipulation tasks.
Advancing AI Manipulation Capabilities
1X emphasizes that this hand upgrade represents more than a hardware milestone: it is intended to accelerate progress in AI-driven manipulation. The high degree of freedom and rich sensory data will provide machine learning models with more comprehensive input, helping NEO perform complex tasks in home and industrial environments with greater reliability.
As of the time of publication, 1X has not disclosed a formal mass-production schedule or commercialization roadmap for the new hand. Further developments are expected to follow.
