OctoH-Hand

Brand Story

One Foundation Model. Across Embodiments. Across Tasks.

Intelligence is distributed across the octopus’s eight arms—each arm can sense and respond on its own.

Intelligence enters the physical world through touch. With acute perception and highly flexible arms, the octopus understands its surroundings and adapts its movements through physical interaction.

At SynapX, we believe a robotic hand should be more than an actuator. It should be where AI begins to learn and evolve—understanding the world through physical contact and transforming it through unmatched versatility.

Making Hands More Than Actuators—Able to Touch, Sense, and Think.

Product Overview

OctoH-Hand is the first high-DoF biomimetic tendon-driven hand designed for deployment across diverse real-world applications.

Built on a hand–brain co-design architecture, OctoH-Hand introduces the pioneering “Data Collection Twin” solution. By aligning the kinematic configuration and sensing systems of the dexterous hand with those of the data-collection device, it bridges the retargeting gap, allowing captured motions to be reproduced directly on the robotic hand while significantly improving data quality and collection efficiency.

Key Differentiators

Data Collection Twin

A kinematically matched data-collection glove and dexterous hand enable captured data to be used directly, bridging the retargeting gap and significantly improving data quality and collection efficiency.

Ultimate Biomimicry

Anatomically accurate proportions deliver true-to-life form, while an n+1 fully actuated, tendon-driven joint architecture enables natural, human-hand-like motion.

Full Closed-Loop Force Control

Backdrivable joints combine motor-current feedback with tactile sensing in a fully closed-loop force-control system, enabling responsive, force-aware manipulation.

Stable & Reliable

Long-lasting peak performance: a 1,000-hour MTBF, with auto-tuning that maintains repeatability at ≤ 0.1 mm.

Integrated Arm-Hand System

Hand joint actuators are remotely integrated into the forearm via a motor-tower architecture, enabling an ultra-lightweight end-effector for humanoid robots.

High-DoF · 23 Degrees of Freedom

Forearm: 3 DoF (Direct Motor Drive) + Hand: 20 DoF (Tendon-Driven). Higher Degrees of Freedom Enable Greater Manipulation Capabilities.

Multimodal Perception

All 20 DoF are equipped with angle sensors for precise joint-position sensing. Backdrivable actuators enable force sensing through motor-current variations induced by external forces. Large-area tactile arrays cover the palm and finger surfaces, while a wrist-mounted tracking camera expands multimodal perception to beyond-human capabilities.

Tactile Glove

Integrates 1,900+ tactile sensing units with an array pitch of ≤ 1 mm. Its multi-layer architecture features a rigid substrate layer that eliminates tactile signal slippage and positional deviation.

Mechanical Backdrivability

Passive backdrivability even without power, ensuring safe and reliable human-robot interaction.
