Reality check
It is really working in factories, but there is no price and no purchase path for outsiders, so unless you are a large manufacturer becoming a partner, you cannot get one.
Can you get one, and what will it cost?
A planning estimate with machine, freight, duty, and tax shown separately.
You cannot order the Walker S2 today: it is b2b only.

Price notes: No public price. Third-party estimates scatter wildly ($68k-$180k, plus a $5k/month RaaS claim); none confirmed by UBTech. The official channel is 'reach out to become a partner'. Mass production started Nov 2025; UBTech has since reported 1,079 full-size Walker S2 units delivered in 2025 and a Walker-series order book around RMB 1.4 billion, so this is one of the few enterprise humanoids with a delivery record rather than a pilot count. It is still not something you can order at a price.
