In a stunning display of technological advancement, China’s Unitree Robotics has unveiled its latest feat, a humanoid robot that can perform kung fu moves with astonishing precision and balance.
The G1, Unitree’s compact humanoid robot has transformed from a nimble dancer to a martial arts master, showcasing the rapid progress in robotics and artificial intelligence.

From virtual training to real-world mastery
Unitree’s approach to developing the G1’s skills is as fascinating as the robot itself.
The process begins in a virtual environment using Nvidia’s Isaac Simulator, whereby the robot learns complex behaviors before it even exists in physical form. This innovative method involves creating a digital twin of the humanoid robot that observes and learns from human actions using motion capture and video data.
The behaviors are then refined through reinforcement learning in the virtual world. Subsequently, these acquired skills are transferred to the physical robot using a technique called Sim2Real, which seamlessly bridges the gap between simulated actions and real-world applications.

In its latest video demonstration, the G1 humanoid robot performs an array of impressive kung fu movements with remarkable balance and agility. The robot executes punches, roundhouse kicks and other complex martial arts techniques, showcasing its enhanced coordination and flexibility. With 23 degrees of freedom, the G1 demonstrates a level of dexterity that would make even Bruce Lee raise an eyebrow.

Beyond martial arts: A versatile helper
While the kung fu demonstration is undoubtedly eye-catching, Unitree envisions a broader role for its humanoid robots. The company positions the G1 as a versatile machine capable of handling challenging, repetitive tasks across various settings, including homes, factories and hospitals. This aligns with Unitree’s vision of humanoid robots serving as useful companions in both work and daily life.

Open-source innovation
To further advance the natural movement of its humanoid robots, Unitree has released an open-source full-body dataset. This dataset, compatible with the G1, H1 and H1-2 models, enables the robots to perform human-like motions with improved flexibility and coordination. The dataset incorporates a redirection algorithm that optimizes the robots’ movements, taking into account factors such as end posture constraints, joint positions and velocity limitations.
