Unitree H2-D Review: Specs and Uses of the Heavy-Payload Column-Lift Humanoid
Updated: 7 days ago
The Unitree H2-D is the upper body of the full-size H2 humanoid on a lifting column, with an optional mobile chassis. Unitree does not list a price on the product page. This review covers its specifications, versions and uses.
Quick Verdict
The H2-D is the heavy counterpart of the G1-D. Its arms are rated for about 7 kg each and about 15 kg at peak, with joints of up to 120 N·m, so it can handle real workpieces, not only light objects. The column raises the body between 1200 and 1700 mm overall. The Standard version stands on a base that is moved by hand, weighs about 148 kg and is meant to run from mains power around the clock. The Flagship has a differential-drive chassis, moves at up to 1.5 m/s and runs about five hours on a 1.44 kWh battery. Two onboard computers, an Intel Core i5 and a Core i7, are standard.
