Unitree G1 Review: Specs, Price and Uses of the 35 kg Humanoid Robot
Updated: 7 days ago
The Unitree G1 is a humanoid robot 1.32 m tall that weighs about 35 kg and has 23 degrees of freedom, listed from USD 13,500 by the manufacturer. This review covers its specifications, design, versions, uses and price.
Quick Verdict
The G1 is the humanoid that made the category affordable to laboratories and developers. For USD 13,500 the standard version offers a compact body that folds for transport, a 3D LiDAR and depth camera, and a battery that lasts about two hours. It is not an industrial worker: each arm lifts about 2 kg, and the standard version does not allow users to develop their own software. For research and development the G1 EDU adds joints, torque, computing options and development access, at a price given only on request.

Connectivity: Wi-Fi 6 and Bluetooth 5.2
Computing: 8-core processor; the EDU can add a module such as NVIDIA Orin
Optional three-fingered Dex3-1 hand with force control, adding 7 degrees of freedom per hand
Walking speed is not listed on the product page
Design and Build Quality
The G1 is small for a humanoid: 1.32 m tall and about 35 kg, where full-size humanoids stand around 1.7 to 1.8 m. That makes it easier and safer to handle in a laboratory. It folds to 690 mm in height for transport or storage. The battery is released quickly for swapping. The knee, the strongest joint, delivers up to 90 N·m in the standard version and 120 N·m in the EDU. An optional hand with three fingers and force control can be fitted, with tactile sensors as a further option.
Software and Development
Updates
The robot receives software upgrades over the air.
Development Access
Only the G1 EDU supports secondary development, that is, users writing their own control software. Buyers who intend to do research should therefore look at the EDU and not at the standard version.
Computing
The standard robot has an 8-core processor. The EDU can be fitted with a high-performance computing module for AI workloads.
Unitree G1 Uses
The G1 is used mainly for research, development and demonstration.
Research and AI Development
With the EDU version, universities and companies use the G1 as a platform for work on walking, manipulation and robot learning.
Education and Demonstration
The standard version serves for teaching, exhibitions and public demonstration.
Limits
With an arm load of 2 to 3 kg and two hours of battery, the G1 is not designed for continuous industrial work.
Unitree G1 Price and Value
The Unitree G1 is listed at USD 13,500 by the manufacturer, excluding tax and shipping. The G1 EDU is priced on request. Hands, computing modules and other options add to the price. Prices are indicative, are not final and may change.
