Walker S2

UBTECH · ChinaChina

UBTECH’s factory humanoid that swaps its own battery in about 3 minutes.

Walker S2 is UBTECH’s industrial humanoid. The headline feature is a hot-swappable battery that the robot changes on its own in about 3 minutes, so it can keep a line running around the clock.

UBTECH says the waist rotates ±162° and the robot can lift 15 kg across a 0–1.8 m workspace. In November 2025 the company announced mass production and delivery. There is no public price.
