Unitree G1-D Review: Specs and Uses of the Column-Lift Humanoid for Data Collection
Updated: 7 days ago
The Unitree G1-D is a version of the G1 humanoid in which the legs are replaced by a lifting column, with an optional mobile base. Unitree does not list a price on the product page. This review covers its specifications, versions and uses.
Quick Verdict
The G1-D is a tool for teaching robots by demonstration. Collecting manipulation data does not need walking, so Unitree mounts the G1 upper body, with seven-axis arms and wrist cameras, on a column that raises it between 1260 and 1680 mm overall. The Standard version stands on a base and runs about two hours. The Ultimate adds a differential-drive chassis with LiDAR and depth cameras, moves at 1.5 m/s and runs about six hours on a second battery. Each arm carries about 3 kg. Grippers, three-finger hands and five-finger hands can be fitted. At about 90 kg it is a workstation robot, not a portable one.
