UBTech Walker S2 humanoid robot, tracked: no published price
UBTech has never published a price for the Walker S2 in any language, and the only figure with arithmetic behind it is the RMB 760,479 (about $112,700) of revenue per full-size humanoid implied by UBTech's own 2025 results, 1,079 units for RMB 820.6 million.
The Walker S2 humanoid robot clears a bar most machines on this site never get near. It is mass produced, sold in volume, and clocking shifts in factories whose names UBTech is happy to print. It has also never had a price. UBTech has published no number for it in English or Chinese, and the closest thing to one is a division problem you can do on its annual results.
UBTech's FY2025 annual results announcement, filed with the Hong Kong exchange on March 31, 2026, reports revenue of RMB 820.6 million from "full-size embodied intelligent humanoid robot products and services" on a sales volume of 1,079 units. That is RMB 760,479 per unit, about $112,700 at the 2026-08-06 ECB reference rate of 6.7491. Every dollar figure on a spec-aggregator page is something else.
Status box

- Published price: None, in either language, as of 2026-08-07
- Implied revenue per unit (2025): RMB 760,479, about $112,700, blended across the full-size humanoid line and its services
- Units sold (2025): 1,079, off a base so small the filing puts the growth at 35,866.7%
- Mass production start: November 17, 2025, first batch of "several hundred"
- Order book: more than RMB 800 million (about US$112 million) in Walker S2 orders since early 2025, per UBTech's announcement that day

The maker publishes a parts diagram where the spec table should be
UBTech's Walker S2 page has a section headed "Product Specifications." I went to read it. It is two images, one for desktop and one for mobile, both showing a front and back view of the robot with callout lines pointing at its sensors: fish-eye cameras x2, RGB cameras x2, LED screen x1, microphone x1, speakers x2, RGBD x1, six-axis force sensors x2, dexterous hands x2, a power switch, an emergency stop, a gigabit Ethernet port and a fast charging port. The Chinese page carries the identical diagram with Chinese labels.
No height. No weight. No degrees of freedom. No battery capacity. No walking speed. No price.
That gap has been open for a year. When New Atlas covered the reveal on July 21, 2025, it noted that UBTech "is yet to detail its new humanoid so pretty much all we have is speculation at the moment," and signed off waiting for a product page with "full specs, pricing and availability." The product page arrived. The specs and the pricing did not.
The page's own SEO keyword list, sitting in the HTML, reads: ubtech walker s2,walker s2,ubtech walker s2,ubtech walker s2 robot,ubtech walker s2 price,ubtech walker s2 tennis. UBTech is chasing the phrase "walker s2 price" with a page that has no price on it.
The only price signal with a source behind it
| Figure (FY2025, UBTech's own filing) | Value |
|---|---|
| Full-size humanoid revenue | RMB 820.6 million (about $121.6 million) |
| Full-size humanoid units sold | 1,079 |
| Implied revenue per unit | RMB 760,479, about $112,700 |
| Year-on-year revenue growth | 2,203.7% |
| Group gross margin | 37.7%, up 9 points, credited to humanoids becoming the biggest revenue line |
| Group net loss | RMB 789.8 million |
That number is a signal rather than a sticker. The line item reads "products and services," so support and software sit inside it, it covers UBTech's whole full-size humanoid range rather than the Walker S2 alone, and revenue recognition need not track unit shipment quarter by quarter.
What it establishes is a floor under the guesswork. A machine averaging three quarters of a million yuan of revenue apiece is not a five-figure machine.
What the spec sites print instead
I loaded three aggregator pages that rank for this robot and copied what they claim.
| Source | Price shown | Height | Weight |
|---|---|---|---|
| UBTech (maker) | not published | not published | not published |
| robotomated.com | $90,000 | not shown | not shown |
| robolist.ai | $99,995 to $314,286 | 176 cm | 95 kg |
| roboselect360.com | $68,000 to $120,000 | 176 cm | 70 kg |
Robotomated prints "$90,000" as an MSRP, then stacks a total-cost-of-ownership table, a maintenance estimate and a payback-period calculator on top of it, all resting on a number the manufacturer has never stated. The same page calls the Walker S2 a "second-generation Walker with 42 DoF." UBTech's annual report calls it the third-generation industrial humanoid with a 52 degree-of-freedom bionic torso. Roboselect360 is the most careful of the three: it prints a range, then admits in the same breath that there is "no official public pricing."
Height is the one number that travels intact at 176 cm, and it comes from Chinese reference pages rather than UBTech. Weight runs from 70 kg to 95 kg depending on which site you open, a 25 kg spread on a robot that supposedly has a spec sheet. The pattern is the one that produced the phantom $25,000 in the T800 listings: one unsourced figure gets typed, then copied, then dressed up with decimal places.
What the Walker S2 humanoid robot actually does
The headline feature is real, and as far as I can find it is genuinely a first. The Walker S2 carries two batteries and swaps a depleted one for a charged one at a station, by itself, in about three minutes, which is what lets UBTech claim continuous operation rather than shift-length operation. Its Chinese page rates endurance at four hours or more per cycle. UBTech filmed the swap, and the footage is the closest the company comes to publishing anything about this robot.
The rest of the published capability set: a 52 DoF bionic torso, 15 kg lifted anywhere in a 0 to 1.8 m vertical working range, ±162° of waist rotation, 125° of pitch, and a fourth-generation dexterous hand with an 11 DoF structure. The work it is sold for is narrow: handling, sorting and quality inspection, which the annual report describes as taking over "specific job tasks previously performed by humans." This is a machine that unloads totes and checks charging-gun connections, and nothing in UBTech's materials pretends otherwise, which is more restraint than most of this industry manages.
A humanoid doing backflips looks incredible and tells you almost nothing about whether it can do real work in a real facility. That takes an entire ecosystem behind it. (@agilityrobotics, 2026-08-10)
Who has one
The November 17, 2025 mass-production announcement put a first batch of "several hundred" units out the door and tallied more than RMB 800 million in Walker S2 orders since the start of that year, including a RMB 159 million data-centre deployment in Zigong and a RMB 250 million contract signed that September. China Daily reported that deal on September 9, 2025 as centring on the Walker S2.
Europe arrived last month. UBTech named Terra Robotics its exclusive distributor for Germany, Switzerland and Austria on July 13, 2026, with Walker S2 units going into ROSSMANN logistics centres on an initial purchase of "several dozen" full-size humanoids.
The trajectory chief branding officer Michael Tam gave the South China Morning Post on November 19, 2025: 500 industrial humanoids delivered in 2025, up to 5,000 in 2026, 10,000 in 2027, manufacturing cost falling 20 to 30 percent a year, and unit production cost "under US$20,000" some time between 2027 and 2030. The 500 counts industrial deliveries and the audited 1,079 counts the whole full-size category, so those are not the same fence being cleared.
What a US buyer runs into
Everything above happened somewhere else. There is no US distributor for the Walker S2, no US price, and no purchase path that does not start with a contact form in Shenzhen. On July 28, 2026 the FCC barred new equipment authorizations for Chinese-made humanoid robots and robot dogs, effective immediately, sparing only models already authorized for US sale, as Al Jazeera reported the following day. A robot with no prior authorization and no US channel now has a regulatory wall behind the commercial one, and what that did to the whole import list is in the Chinese humanoid consumer map.
For a full-size humanoid you can actually complete a purchase for, the dated live options are in how much a humanoid robot costs, and the Unitree G1 at $13,500 remains the machine everything else gets measured against. For where UBTech sits among makers with and without a checkout, see the humanoid companies mapped.
Three things would put a real number on it
UBTech's 2026 interim results, due around late August on last year's schedule, which will show whether the 5,000-unit run rate is real and reset the revenue-per-unit arithmetic. A price from UBTech itself, in any currency, printed on the page that is already chasing the phrase. Or Terra Robotics quoting a figure for a ROSSMANN-sized order in public rather than in a sales thread.
Until one of those lands, RMB 760,479 stays what it has been since March: a division problem with a filing behind it, and the only figure on this robot that anyone can show their work on.
