## Summary

The exploration of humanoid robotics reveals significant differences between the U.S. and China in terms of manufacturing capabilities, economic incentives, and technological advancements. While the U.S. focuses on high-level autonomous tasks, China is rapidly developing a robust robotics ecosystem driven by government support and a willingness to absorb early losses in capital investment.

- General-purpose robotics face software challenges, with hardware advancements largely driven by existing technologies from EVs and consumer electronics.
- China is a leader in robotics manufacturing, leveraging its extensive supply chain and rapid iteration capabilities.
- The economic justification for humanoid robots differs between the U.S. and China, with China actively creating demand through state support and cultural initiatives.
- U.S. investors are cautious about robotics ventures, while Chinese capital markets are more willing to invest in early-stage manufacturing.
- Companies are increasingly operating across borders, utilizing U.S. AI development alongside China's manufacturing strengths.
- Rising tariffs are prompting suppliers to relocate assembly to other countries, but Chinese firms maintain a significant knowledge advantage.
- Chinese robotics research is advancing rapidly, narrowing the gap with Western innovations.
- The journey sparked a commitment to further exploration and collaboration in the robotics field, emphasizing the importance of continuous learning and building.

Over the past few years, General-purpose robotics have sold a vision of hardware that 
can do possibly any task a human can. The biggest bottleneck to robotics has 
been the software. As VCs and engineers at these companies, this is our day to day. We wanted to understand the components of 
humanoid robotics from first principles. So we spent months breaking the 
system down, piece by piece. But you can't understand the reality of this 
industry by looking at a screen in California.

[[0:22]](https://www.youtube.com/watch?v=gQ3VcfAgXZA&t=22s)
You have to speak to the people iterating 
on the hardware. So our crew went to China… After a 15-hour flight, we landed in Shanghai. Over the next 10 days, our journey brought us 
to hotspots in the supply chain like Sūzhōu, Hángzhōu, Shēnzhèn, and Dōngguǎn. To build a humanoid, you need four things: 
Sensors, a Brain, a Battery, and Actuators. Very few parts need to be made 
from scratch and manufacturing capabilities rests on the shoulders of giants. The development of EVs, drones, 
and consumer electronics has accelerated robotics hardware manufacturing.

[[0:54]](https://www.youtube.com/watch?v=gQ3VcfAgXZA&t=54s)
China produced over 12 million EVs in 2024, which commoditized the lithium-ion 
batteries now powering humanoids. DJI spent a decade perfecting 
high-torque motors—those same motors now drive robotic actuators. And the cameras and sensors in your iPhone are now off-the-shelf components 
for any robot manufacturer. China has tremendous capabilities to drive 
actual innovation. Take the dexterous hand. We met multiple teams in China building hands that 
rival Tesla's—like this one from Sharpa Robotics. They’ve previously scaled Lidar 
from costing $50K to $500; today they are trying to create 
far more affordable robotics hands.

[[1:25]](https://www.youtube.com/watch?v=gQ3VcfAgXZA&t=85s)
And the speed of it all is staggering. In Suzhou, a micro-actuator factory 
turns raw metal rods into precision joints. If a part fails, they fix the 
design and cut a new one by lunch. A gripper manufacturer told us every component 
they need is within a 25-minute drive of his office. Founded five months ago, the company’s 
already gathered 10,000+ hours of robotics data. After visiting factory after factory, we 
began to see a fundamental difference: the US and China are building general-purpose 
robots with completely different constraints.

[[1:52]](https://www.youtube.com/watch?v=gQ3VcfAgXZA&t=112s)
First: Demand In the US, everyone’s racing to build a foundation 
model that could allow a robot to enter an unseen home and clean a kitchen or make a bed, or get 
deployed in any car factory and wire a harness, all from a single high-level command with minimal 
fine-tuning or robot technicians involved. An $80,000-a-year wage doesn't justify a humanoid robot on economics alone until it 
can perform reliably, end-to-end. In China, a $15,000-a-year wage doesn't justify 
a humanoid robot on economics alone either.

[[2:17]](https://www.youtube.com/watch?v=gQ3VcfAgXZA&t=137s)
But demand is actively being created—by 
both the state and capital markets. Contrary to the US definition of 
success, Beijing wants China to be the world’s factory for robotics. As 
a result, many robotics companies here optimize less for peak intelligence, 
and more by quantity of robots sold. China does this in a few ways: Provincial government owned facilities like 
museums and hospitals act as anchor customers, and are encouraged to deploy humanoid robots. Robots perform at the Spring Festival Gala, at concerts, creating cultural momentum. And 
quietly, there are circular supply chains.

[[2:45]](https://www.youtube.com/watch?v=gQ3VcfAgXZA&t=165s)
A motor supplier might buy robots from 
the OEM they supply to. It's not optimal, but it keeps factories running 
and iteration loops alive. Second: Capital Robotics is often referred to as the graveyard of 
venture capital, and for good historical reason. In the U.S., investors are deeply cautious about 
factories optimized for first-generation robots. China’s capital system, by contrast, is 
far more willing to absorb early losses. The bet is that early manufacturing 
dominance matters more than early profits.

[[3:09]](https://www.youtube.com/watch?v=gQ3VcfAgXZA&t=189s)
A single announcement that a company has become 
a supplier to Tesla can send a stock up 50%, creating incentives that benefit both sides. Suppliers gain credibility, 
volume, and capital-market upside, while Tesla sees the real time creation of 
a supply chain that didn’t exist before, and one that is constantly fighting 
to be faster, cheaper, and better. General-purpose robotics is a major 
technological frontier where the US and China started investing at roughly the same time.
There is no clear head start or clear winner.

[[3:34]](https://www.youtube.com/watch?v=gQ3VcfAgXZA&t=214s)
After months of research and time on the 
ground, we came away with three observations: First: Some companies are learning to 
operate across both worlds—developing AI in the US while leveraging 
China's manufacturing ecosystem. Second: With rising tariffs, suppliers are shifting assembly to 
Thailand, Mexico, and elsewhere. Today, Chinese companies possess 
the lion share of process knowledge. Companies with process knowledge that can replicate their capabilities abroad 
have structural advantage over time. And third—this surprised us—Chinese 
robotics research is much closer to the frontier than most people in the West realize.

[[4:04]](https://www.youtube.com/watch?v=gQ3VcfAgXZA&t=244s)
The best work coming out of China is 
improving fast and closing the gap. So how do we feel after ten 
days of running around China, wrapping it all up on the very last day of 2025? Honestly? A mix of excitement. Accomplishment. 
And this sense of calling. The more we pulled on this thread, the more we 
realized there’s still so much to learn and build. As we pack our bags and head back to our normal 
lives, we didn’t want this trip to just… end.

[[4:25]](https://www.youtube.com/watch?v=gQ3VcfAgXZA&t=265s)
So for anyone else who dreams 
of the future and feels this same pull to build intuition 
on the frontier of robotics, we put together this resource 
and with the help of dozens of experts who reviewed our work and kept us honest. All of that lives here, on this site. For anyone who’s interested. And for us, this is just the beginning.
