Humanoid Robots Brave the Cold: Unitree G1’s Historic Walk in Extreme Temperatures

The vision of robots assisting—or even replacing—humans in hazardous environments is steadily becoming a reality. A recent demonstration by Chinese robotics company Unitree Robotics showcases significant progress in this field, with its G1 humanoid robot completing an autonomous walk in sub-zero temperatures.

A Test of Endurance in the Altay Region

The Unitree G1 recently undertook a challenging trek across the snow-covered Altay region of Xinjiang, China, becoming the first humanoid robot documented to complete an autonomous walk in such extreme cold. Temperatures plummeted to -47.4 degrees Celsius (-53 degrees Fahrenheit) during the test—a temperature capable of disabling conventional electronics like smartphones and tablets. This feat highlights the potential for robots to operate in environments inhospitable to humans.

Beyond a Publicity Stunt: Practical Applications

This wasn’t merely a demonstration of robotic capability. it was a practical test of cold-climate robotics. The successful walk suggests a future where robots can reduce human exposure to dangerous, ultra-low temperature work environments. While concerns about robots taking jobs exist, many roles involve conditions few humans would willingly endure.

Preparing for the Freeze

Like humans, robots require protection from extreme cold. The Unitree G1 was equipped with an orange insulated winter coat and plastic sleeves around its legs and feet to shield its motors, joints, and battery packs. The robot too completed a pre-planned task during its walk: creating an Olympic emblem, measuring approximately 610 feet long and 328 feet wide, in the snow while navigating uneven terrain.

Technical Specifications of the G1

The G1 humanoid robot boasts between 23 and 43 joint motors, depending on its configuration, and is powered by a quick-release battery providing around two hours of operational life. It utilizes advanced sensors, including 3D LiDAR and depth cameras, a noise-cancelling microphone for voice control, and China’s BeiDou Navigation Satellite System for precise positioning. Adaptive path-planning software enables the robot to maintain balance and efficiently complete its tasks. The G1 can walk at a maximum speed of approximately 4.5 miles per hour.

Availability and Future Prospects

Unitree Robotics currently sells the G1, alongside other four-legged robotic platforms. The G1 starts at around $14,240, and the company sold approximately 4,200 units in 2025. Currently, the G1 is primarily used in pilot and test sites, paving the way for potential applications in cold-storage warehouses, snow removal, and arctic scientific research.

While the dream of robots like Rosie from The Jetsons fetching slippers may still be distant, the Unitree G1’s successful cold-weather walk represents a significant step toward a future where robots routinely work alongside humans in challenging and hazardous conditions.
