China’s UBTech Robotics has signed a 264 million yuan (US$37 million) deal to deploy its Walker S2 humanoid robots at border checkpoints in Fangchenggang, Guangxi — a coastal city on the border with Vietnam. Deliveries begin in December 2025.

Launched in July 2025, the Walker S2 is promoted as the world’s first humanoid robot that can swap its own battery. It can replace its power pack in about three minutes, allowing near 24/7 operation without human help.

The robots will help guide travelers, manage crowds, assist with patrols, support logistics, and perform inspections. Beyond immigration sites, they’ll also be used in nearby manufacturing facilities, including steel, copper, and aluminum plants.

The Walker S2 stands about 1.76 meters tall, has 52 degrees of freedom, and features dexterous hands for precise operations.

This is one of China’s biggest real-world tests of humanoid robots, moving them closer to practical use in government and industry.
