Unitree Unveils Dex2/5 Dexterous Hand for Unitree G1 and Unitree R1

Unitree Robotics has detailed its new Dex2/5 end-effector, a lightweight five-finger robotic hand built specifically for the Unitree G1 and Unitree R1 humanoid platforms. As enterprise buyers scrutinize total system costs, end-effector complexity remains one of the primary cost drivers in bipedal hardware.

The Dex2/5 departs from fully articulated, multi-motor hands by adopting an underactuated mechanical layout powered by just two electric motors. Utilizing precision gearing and tendon transmission, one actuator controls thumb opposition while the second motor coordinates the flex of the remaining four digits. This design significantly trims thermal output, power consumption, and overall hand mass without sacrificing essential power-grasp capabilities.

For facility operations managers, high-degree-of-freedom hands often represent fragile, high-maintenance points of failure on the factory floor. By streamlining the internal mechanical layout, Unitree aims to improve hardware reliability during repetitive bin-picking and light material handling while preserving a human-like form factor for shared workspace interaction.

The introduction of the Dex2/5 underscores a broader commercial trend in humanoid robotics: balancing dexterity against capital expenditure. As low-cost platforms like the Unitree G1 target broader industrial adoption, simplified end-effectors will be key to keeping replacement costs manageable and uptime high.
