Unitree’s humanoid robot G1 has completed an endurance test in extreme winter conditions, taking more than 130,000 steps in sub-zero temperatures to carve the Olympic Winter Games logo into snow in northwest China, according to the company and published footage.
The demonstration took place in the Altay region of Xinjiang, where temperatures fell as low as minus 53.3 degrees Fahrenheit (minus 47.4 degrees Celsius), conditions that exceed the operating range of most conventional electronics. The robot crossed untouched snow to trace a large-scale Olympic emblem as part of a project linked to preparations for the 2026 Winter Games.

Unitree said the G1 was modified specifically for the task, using a thermal jacket, insulated battery systems, protected joints and software adapted for extreme cold. Navigation relied on China’s Beidou satellite system, which the company said provided positioning accuracy of about 10 centimeters. “The entire operation was carried out without any human intervention,” Unitree said.
Standing 1.27 meters tall and weighing about 35 kilograms, the robot carved a logo measuring roughly 186 by 100 meters, according to the company. A video released on Feb. 2 shows brief clips of the G1 walking in the snow before cutting to the completed design, which appears sharply defined despite the harsh terrain.
Robotics experts note that deep snow and prolonged exposure to extreme cold place significant strain on motors, batteries and control systems, making precise movement difficult. While some online viewers questioned the authenticity of the footage, most reactions praised the demonstration as a sign of growing robustness in humanoid robotics under real-world conditions.
