Unitree Impressive Capabilities of the G1 and G1 EDU Humanoid Robots

Updated: May 13 2024 17:46
Humanoid robots are becoming increasingly advanced, and the G1 and G1 EDU models from Unitree Robotics are prime examples of the cutting-edge technology in this field. These robots boast an impressive array of mechanical dimensions, electrical characteristics, and accessories that set them apart from other humanoid robots on the market.



The G1 and G1 EDU models have a height of 1270mm, width of 450mm, and thickness of 200mm when standing. When folded, their dimensions are 690x450x300mm. Despite their compact size, these robots pack a lot of power and flexibility. The G1 weighs about 35kg with the battery, while the G1 EDU is slightly heavier.

One of the most impressive features of these robots is their joint freedom. Both models have a total of 23 degrees of freedom, with the G1 EDU having the option to expand up to 43 degrees of freedom. Each leg has 6 degrees of freedom, and the waist has 1 degree of freedom (with an optional 2 additional degrees). The arms have 5 degrees of freedom each, and the G1 EDU can be equipped with a three-fingered dexterous hand that adds 7 more degrees of freedom per hand.


The G1 and G1 EDU are not only flexible but also strong. The maximum torque of the knee joint is 90N.m for the G1 and 120N.m for the G1 EDU. The arm maximum load is about 2Kg for the G1 and 3Kg for the G1 EDU. These robots have an impressive range of motion, with extra-large joint movement spaces in the waist, knee, and hip joints.



In terms of electrical characteristics, both models feature full joint hollow electrical routing, dual encoders for each joint, and a local air cooling system. They are powered by a 13-string lithium battery and have an 8-core high-performance CPU for basic computing power.

The G1 and G1 EDU are equipped with a depth camera and 3D LiDAR for sensing their environment. They also have WiFi 6 and Bluetooth 5.2 connectivity.


The G1 EDU model can be upgraded with an NVIDIA Jetson Orin high computing power module for even more advanced capabilities. Both models come with a 9000mAh smart battery that is quick to release and a 54V 5A charger. A manual controller is also included.



The battery life for both models is about 2 hours, depending on usage. They also feature upgraded intelligent OTA (over-the-air) updates. The G1 comes with an 8-month warranty, while the G1 EDU has a 1-year warranty. Here are the full specification of the humanoid robots:




The G1 model is priced at US $16K (tax and shipping cost excluded), while the price for the G1 EDU is available upon contact with sales. This is much cheaper than the earlier H1 Humanoid robot set at $150K price tag.

The G1 and G1 EDU humanoid robots from Unitree Robotics are impressive machines that showcase the latest advancements in robotics technology. With their extensive range of motion, strength, and advanced sensors and computing power, these robots are well-suited for a variety of applications in research, education, and beyond.
