Quick Answer
Noetix Bumi is Songyan Dynamics’ small consumer/education biped. The numbers we will use are the ones in Noetix’s own Bumi documentation: 98 cm × 35 cm × 20 cm standing, about 17 kg with battery, 21 degrees of freedom, 2–3 hour quick-release pack. That is not Dora. Dora is a different Noetix card on this site. It is also not the 94 cm / 12 kg pair that launch-week blogs copied in October 2025. When the manufacturer’s doc and the launch blog disagree, the doc wins.
Price in the pre-WRC public card we already track is about 9,998 yuan (~$1,400). That is a China consumer number, not a WRC-day markdown we watched get scanned at Beiren Etrong. Bumi has been on a Spring Festival stage and, this August, on a WRC dance booth. Cute, cheap for a walker, and still a 17 kg machine that can take a child out at the knee if you treat it like a stuffed toy.
Our Verdict
| Field | Rating | Notes |
|---|---|---|
| Overall Review Score | 6.4 / 10 | As a priced edu/home biped. As a serious research humanoid: you already know this is the wrong aisle. |
| Education / hobby value | 7.4 / 10 | Graphical programming, an app, a sub-10k-yuan walker. That combination is the point. |
| Commercial labor readiness | 1.0 / 10 | 21 DOF and 17 kg. Nobody is staffing a line with Bumi. |
| Consumer readiness | 5.5 / 10 | Closest thing in this batch to a home SKU. Still needs a sober adult in the room. |
| Autonomy confidence | Low to medium scripted | Voice, dance, app. Not a household employee. |
| Source confidence | High on the official doc rows | web.noetixrobotics.com/docs/. Launch blogs that say 12 kg are secondary. |
What Bumi is
Noetix Robotics (松延动力, Beijing) built a child-scale walker and priced it like a high-end appliance instead of a lab instrument. TechNode’s 22 October 2025 note called it the first high-performance humanoid under ¥10,000 and used the older 94 cm / 12 kg figures. By the time the comprehensive doc shipped, the standing box was 98 × 35 × 20 cm and mass was “about 17 kg.” We are not averaging those. We are using the doc.
The featured photograph is a full-body three-quarter of the white production-looking unit with NOETIX across the chest — not a Dora hero, not a rear-view prototype still. If a page on this site shows a different Noetix body and calls it Bumi, that page is wrong.
Hardware, from the manual
| Specification | Value | Confidence |
|---|---|---|
| Standing size | 98 cm × 35 cm × 20 cm | Official doc |
| Mass with battery | About 17 kg | Official doc |
| Total DOF | 21 (leg 6 + arm 4 + waist 1, per side as listed) | Official doc |
| Runtime | 2–3 hours | Official doc |
| Battery | Quick-release lithium pack | Official doc |
| Base compute | 6 TOPS on the motion board | Official doc |
| Edu compute | Optional NVIDIA Jetson Orin Nano Super / NX on listed edu SKUs | Official doc; not every SKU |
| Price | ~9,998 yuan public card | Pre-WRC public figure, not a floor scan |
| Payload | Not published | Blank. Do not invent one. |
Hands on the production photo are simple white end-effectors, not five-finger dexterous hands. Joint peak torque in the doc is 70 N·m. That is a kid-scale actuator, not a G1-class industrial number. EDU SKUs add a RealSense on most variants and open the low-level controller. The stock home unit does not pretend to be that.
What it can do
Walk, dance, take voice, run an app, do classroom graphical programs. Noetix put Bumi on a UN Asia-Pacific forum booth and, earlier, on a Spring Festival stage. WRC 2026 had a dance booth. Those are reliability-for-a-show claims, not “it lives in your house and puts away dishes” claims. The open interface is the upgrade path for a teacher who wants more than the shipped dances.
What it cannot do: carry a useful warehouse payload, climb as a research athlete, or replace N2, which is Noetix’s larger, race-shaped sibling. N2 is the one that showed up in half-marathon coverage. Bumi is the cheap little brother. Do not file them as one robot.
The Dora problem
This site already has a Dora card. Dora is a different Noetix-associated listing. Bumi’s official size is 98 cm / ~17 kg / 21 DOF. If an image pipeline ever used Dora as Bumi, that was a mistake. This review’s featured file has NOETIX on the chest of the small white walker. That is Bumi.
Who should buy it
Schools, makerspaces, parents who understand 17 kg and 21 DOF, and developers who will actually open the edu SDK. Not a warehouse. Not someone who wanted Unitree G1 and saw a price they liked. Not someone who wanted Dora.
Strengths
- A real consumer-shaped price.
- Manufacturer doc with size, mass, DOF, and runtime — we did not have to scrape a blog.
- Small enough to store. Heavy enough that you will not forget it is a machine.
- Distinct from Dora if you look at the photo for more than a second.
Limitations
- 17 kg vs the older 12 kg launch number: the internet will keep quoting the wrong mass.
- Simple hands. 21 DOF. This is not a manipulation platform.
- 2–3 hours, then you swap or wait.
- Safety in a house with kids is on you. Noetix’s “lightweight for home” line is marketing, not a standard.
How it compares
Against Dora: different robot, different card. Against Unitree R1: R1 is the more expensive Unitree compact. Against Unitree G1: G1 is a 35 kg developer biped from $13.5K. Bumi is cheaper, lighter, and less of a lab. Against LimX Luna: Luna is a 160 cm venue adult at RMB 298,000. Different planet.

FAQ
Is Bumi the same robot as Dora?
No. Dora is a different listing. Bumi is the 98 cm / ~17 kg / 21 DOF consumer/edu walker in Noetix’s own doc.
Is it 12 kg or 17 kg?
Official documentation says about 17 kg with battery. October 2025 launch blogs said 12 kg. We use the doc.
How tall is Bumi?
98 cm standing in the official table (98 × 35 × 20 cm). Some secondary pages still say 94 cm.
Can I buy it outside China?
JD.com and China channels are the proven path. English pages exist. We do not have a North America ship date we will invent.
Is the photo a generated stand-in?
No. It is a product photograph of the white Bumi with the NOETIX chest mark.
