A humanoid robot in Seoul learned a K-pop dance routine from a single smartphone video. No motion capture suit, no studio, no choreography software. Just footage, a simulation pipeline, and reinforcement learning doing the rest. The robot is called K0, it comes from a 27 year old actuator company called Robotis, and it is one of at least five serious humanoid efforts now running inside South Korea, all of them aimed at the same target: Unitree's G1.
The timing matters. Nvidia just built a reference humanoid around Unitree's hardware for Isaac GR00T, its full development platform for physical AI. Nvidia has also said it wants to do the same thing with companies in the US, Europe, and South Korea. No Korean company has been named yet. That leaves an open seat at a table South Korea has spent over a year and roughly $770 million trying to get invited to.
South Korea's Robot Lineup, Specs Side by Side
South Korea is not fielding one humanoid contender. It is fielding several, built by different companies, for different jobs, at different price points nobody has confirmed yet. Here is what is actually running right now.
| Robot | Maker | Height / Weight | Degrees of Freedom | Compute |
|---|---|---|---|---|
| K0 (AI Sapiens) | Robotis | 1.3m / 34kg | 23 | NVIDIA Jetson Orin NX, 100 TOPS |
| Igris C | Robros | 1.5m / 56kg | 43 | Intel NUC + Nvidia Jetson Nano |
| KAIST Humanoid v0.7 | KAIST DRCD Lab | 1.66m / 75kg | Not disclosed | Not disclosed |
| Unitree G1 (for comparison) | Unitree, China | ~1.3m / ~35kg | Up to 43 (config dependent) | Onboard AI compute, varies by config |
KAIST's machine is the speed outlier. It runs at 12 km/h on flat ground, climbs steps over 30 centimeters, and its knee actuator delivers up to 320 newton meters of peak torque, according to lab lead Hae-Won Park. The team has already said it wants 14 km/h next, along with ladder climbing and 40 centimeter step capability. That is a research platform chasing mobility records, not a product chasing a price tag.
Robros took the opposite bet. The Igris C tops out at 3.6 km/h, slower than Unitree and Figure's machines by the company's own admission. Robros says that is fine, because Igris C is built for reliability at job sites, not speed records. LG appears to agree: Korean reporting indicates Igris robots are already being piloted inside LG facilities.
Why Open Source Is Robotis's Actual Bet
Robotis has been making actuators since 1999. Its Dynamixel motors already sit inside humanoids built by other companies, including Disney's Olaf bipedal character robot. The K0 is the first time the company has shipped a complete humanoid, and it is doing it as an almost entirely open platform: bill of materials, CAD files, source code, and simulation assets, all released for anyone to fork.
That is the real point of difference against Unitree. Unitree's G1 configurations range from research-grade to commercial, but full customizability is reserved for the higher-end tiers. Robotis is opening the entire K0 platform from day one, pricing included eventually, parts list included now.
The K-pop dance demo was not a stunt for its own sake. It was a proof of concept for the pipeline Robotis wants developers to use: record human motion on an ordinary smartphone, retarget it to the robot's joint structure, train the result in simulation through reinforcement learning, then transfer it to the physical robot. No motion capture studio required. If that pipeline works reliably outside a demo, it lowers the cost of teaching a humanoid new physical skills by a wide margin.
Pricing is still the open question. Robotis has not confirmed a number. Korean reports place it under $10,000, which would put the K0 in roughly the same band as Unitree's G1, currently selling in Korea for about $13,500. Nothing here is official yet.
The Nvidia Seat Nobody's Filled Yet
On June 1, Jensen Huang stood on stage at GTC Taipei and announced the Isaac GR00T Reference Humanoid Robot, a complete bundle of Unitree's H2 Plus chassis, Singapore-based Sharpa's tactile five-finger hands, and Nvidia's own Jetson Thor compute, all validated to work together out of the box. Stanford, ETH Zurich, the Allen Institute for AI, and UC San Diego have already signed on to use it.
Nvidia executives also told reporters the company plans to build the same kind of reference design with humanoid makers in the US, Europe, and South Korea. No names were given. No timeline was given either. That is the entire substance of the Korea claim: a stated intention, attributed to unnamed executives, with nothing signed.
It is still a meaningful gap to watch. Robotis already builds the K0 around an Nvidia Jetson chip. KAIST's research lab already trains its humanoid using the same reinforcement-learning-in-simulation approach Isaac GR00T is built around. If Nvidia wants a Korean partner that fits its existing software stack with minimal friction, the short list mostly writes itself. None of that makes it confirmed.
Where the Money and the Pilots Already Are
Samsung put $181 million into Rainbow Robotics in early 2025, becoming its largest shareholder. Rainbow Robotics was spun out of the same KAIST lab that built the original Hubo, the robot that won the 2015 DARPA Robotics Challenge finals ahead of an early Boston Dynamics Atlas entry. That lineage is a recurring theme in Korean humanoid robotics: a surprising number of today's companies trace back to the same handful of university labs.
Wiii Robotics, founded by former Samsung engineers, raised roughly $68 million in a Series B round in May 2026 for Alex, an upper body only manipulation platform built around a dexterous end effector with 15 degrees of freedom in the wrist and fingers. The company is targeting mass production readiness for late 2027, a date that has not been independently verified.
LG's consumer push is furthest from finished. Its home robot Cloyd debuted at CES 2026 with two five-fingered hands and a wheeled base built for chores like folding laundry. A Tom's Guide hands-on report from the show noted Cloyd moved slowly and left towels folded poorly. Plenty of humanoid robots shipping in 2026 are further along on basic manipulation than that.
My Take
South Korea's actual advantage here is not any single robot. It's that Samsung, LG, and the battery makers already know how to scale hardware nobody else can scale at the same cost, and that infrastructure doesn't care whether it's building phones or robot joints. The K-Humanoid Alliance's government money is small next to what Apptronik or 1X are raising in single rounds, but South Korea isn't trying to out-fund anyone. It's trying to out-manufacture them once somebody else solves the AI brain. That's a narrower bet than China's or America's, and it might be the more disciplined one.
- Robotis's K0 is fully open source and priced to undercut Unitree's G1, but the price itself is still unconfirmed.
- KAIST's research humanoid is chasing speed and mobility records, not commercial deployment.
- Robros's slower Igris C is reportedly already being piloted inside LG, trading speed for reliability.
- Nvidia has said it wants a Korean partner for its Isaac GR00T reference design. As of this writing, it hasn't named one.
FAQ
Is the Robotis K0 humanoid robot available to buy?
Not yet. Robotis has not confirmed a release date or official price. Korean reports estimate it will sell for under $10,000 once available.
Has Nvidia picked a South Korean company for its Isaac GR00T humanoid platform?
No. Nvidia executives have said they intend to build reference designs with companies in South Korea, the US, and Europe, similar to what it did with Unitree, but no Korean partner has been named.
What is the K-Humanoid Alliance?
It's a South Korean government-backed consortium of over 40 companies and universities, launched in April 2025, aimed at developing a shared humanoid AI model and high-spec hardware by 2028. Members include Rainbow Robotics, LG Electronics, Doosan Robotics, Samsung-affiliated battery makers, and several universities including KAIST.
How does the Robotis K0 compare to the Unitree G1?
Both are similarly sized and priced in the same general range. The K0 is fully open source down to the bill of materials, while only Unitree's higher-end G1 configurations offer comparable customizability.
Conclusion
None of South Korea's humanoid makers have shipped a product that beats Unitree on price or Figure on funding. What they have is a manufacturing base that already knows how to scale, a government willing to underwrite the coordination problem, and an open invitation from Nvidia that nobody has formally accepted yet. Whether that adds up to a real competitor or just a well-funded research scene depends entirely on who picks up that invitation first.
