The company Unitree Robotics, known for its quadrupeds such as Go2 and B2, entered the humanoid space last year by introducing its H1 model , demonstrating impressive agility, resisting kicks, executing a backflip and increasing the ability to lift heavy objects.
The G1 Humanoid Agent robot
Recently, Unitree has introduced a new general-purpose all-terrain humanoid called the G1 Humanoid Agent , and it will be priced at $16,000. Although it is not such a cheap price, its technology would be accessible to the general public. This robot offers flexibility, force-controlled dexterous hands, and an imitation learning model, making it easy to integrate into daily activities.
The G1 is also presented in a more compact version , with dimensions of 1270 x 450 x 200 mm when in the stand position and 690 x 450 x 300 mm when folded, making it easy to transport and store. In addition, it weighs approximately 35 kg, including its battery.
On the other hand, its arms have 5 degrees of freedom, while the knee joint has a torque of 90 Nm and a maximum arm load of approximately 2 Kg. It also offers a more advanced version, the G1 EDU robot, designed for commercial or research uses, with knee torque up to 120 Nm and an optional three-fingered dexterous hand (Dex3-1), providing 7 additional degrees of freedom plus 2 for the wrist equipped with touch sensors.

The new Unitree robot models
The G1 and G1 EDU robots share the same limb length, with a calf and thigh of 0.6 m and an arm span of 0.45 m. These characteristics allow wide joint mobility in the waist and hips, achieving impressive flexibility.
The G1 is equipped with electrical routing at the joints, dual encoders, and local air cooling. This robot is powered by a 13-string lithium battery that supports an 8-core high-performance CPU, a depth camera, 3D LiDAR sensors, WiFi 6, and Bluetooth 5.2. Also, the G1 EDU version offers optional computing power with the NVIDIA Jetson Orin module and a 9000 mAh smart battery, providing approximately 2 hours of battery life.
These specifications have resulted in advanced abilities for a humanoid robot. The G1 robot manages to get up from the ground faster than an average human, due to its powerful knee and hip motors, with up to 43 degrees of freedom, demonstrating a great self-stabilization system among current humanoid robots.
The multifunctional design of the G1 robot
The design of the G1 allows it to fold perfectly, favoring both its aesthetics and practicality. It also demonstrates the G1’s ability to acquire skills through imitation and reinforcement learning, although Unitree has not disclosed any further details on this.
Unitree is reportedly using the Nvidia Isaac simulation platform to design, test and train its AI robots. The video illustrates G1 performing stick maneuvers learned through these methods.
The hand strength control feature allows the G1 to perform tasks such as cracking nuts, opening soda bottles, using kitchen items, and even soldering wires. The progress made by Unitree with its new humanoid robot in just a few years of development is remarkable.
