"Footage reveals China's humanoid robot subjected to harsh 'stress test,' depicting apparent abuse by human hands"
In a youtube video posted by an unknown demonstrator, Unitree's G1 humanoid robot undergoes a series of tests to demonstrate its balance, coordination, and durability. The video, shared by Robohub, showcases the robot's ability to withstand sudden impacts, even when subjected to approximately nine kicks from various directions.
The G1 humanoid robot, known for its lightweight frame and flexibility, is not designed for combat but for affordability and accessibility in research and light industrial work. It is equipped with low-inertia, high-speed Permanent Magnet Synchronous Motors (PMSM) across its joints, paired with a dual encoder system for precise feedback.
For spatial awareness, the G1 relies on 3D LiDAR, depth cameras, and an Inertial Measurement Unit (IMU) on its torso. Its internal model of its environment and physical state is constantly updated by these inputs, helping it react quickly to external forces. The robot's movements are governed by a whole-body control framework that coordinates all joints simultaneously as one dynamic system.
Despite the rough treatment, the G1 robot maintains its balance and posture, occasionally swaying or losing footing but quickly regaining control. The only fall the robot suffers in the video appears to be caused by the surface beneath its feet rather than the kicks themselves. The robot slips on a carpet and collapses to the ground, but quickly recovers and springs back upright in less than a second.
The youtube video has drawn attention for its unusual demonstration of the G1 robot's resilience. However, the video's comment section on YouTube is filled with sarcasm and warnings about the potential future of AI. Nevertheless, Unitree, a Chinese robotics company known for its development of advanced mobile robots, including quadruped and humanoid robots, continues to push the boundaries of robotics technology.
