Engineer kicks humanoid robot, yanks it by neck to test stability

An engineer recently conducted a rigorous stability test on the Unitree G1 humanoid robot by forcefully kicking its torso and yanking it by the neck using a chain. The video, shared widely on social media, demonstrated the robot’s ability to maintain balance under significant external disturbances. This test was part of evaluating Any2Track, a humanoid motion tracking system developed by Zhikai Zhang, a PhD student at Tsinghua University, in collaboration with Chinese robotics company Galbot. Any2Track employs a two-stage reinforcement learning framework consisting of AnyTracker, a general motion tracker, and AnyAdapter, an adaptation module that enables the robot to adjust dynamically to real-world disturbances without prior training (zero-shot sim2real transfer). The Unitree G1 robot, featuring 23 degrees of freedom and equipped with 3D LiDAR and depth cameras for precise spatial awareness, is designed for agility, stability, and autonomous movement across complex terrains. It has previously demonstrated smooth walking, running, and even
