BYD, the Chinese firm that overtook Tesla on EV volume, has walked a humanoid robot into one of its car showrooms. It is called Xiao Di (roughly “Little BYD”), it stands 1.61 metres, weighs 58.5kg, and it made its public debut in early August at a “Di Space” experience centre in Zhengzhou. Watch the demo and you will be underwhelmed. That is the point. The robot is the decoy.
On paper Xiao Di is a receptionist. It has 31 degrees of freedom (the number of independent joints it can move), a carry capacity of about one kilo, and a party trick: real-time translation across six Chinese dialects and six foreign languages. BYD wants two or three of them greeting customers in every showroom, explaining which EV to buy and demoing the in-car gadgets. Commercial rollout, they reckon, in one to two years. As a piece of embodied AI (software given a body that can sense and act in the physical world), it is a translator that can wave.
Here is the angle. The machine barely matters. What matters is who built it. BYD already makes roughly three-quarters of its own car parts in-house: the Blade batteries, the motors, the power electronics, the control systems. A humanoid robot is, physically, mostly batteries, motors, actuators and control systems. BYD is not entering the robot business so much as pointing an existing supply chain at a new body.
That is what vertical integration means in practice, owning the factory floor from the battery cells up, and it is exactly the thing pure-play robot startups lack. A well-funded robotics firm has to buy its actuators and battery packs from someone else. BYD’s CEO has said the battery alone can be up to 40% of an EV’s cost, and owning that stack is how BYD undercut Tesla on cars in the first place. Now the same logic gets aimed at a robot.
Now the honest caveat, because BYD has not handed anyone the important numbers: no price, no firm production timeline, no single paying customer. Xiao Di is real and it interacts with visitors, which already puts it ahead of a slide deck. But “showroom greeter you can chat to” is a long way from the factory-labour humanoid that Tesla, Figure and Unitree keep promising. Treat the deployment targets as ambition, not a shipping manifest.
The bigger tell is the backdrop. BYD wheeled out a friendly robot the same stretch its home-market margins took a hit and its car-sales slump got harder to hide. China reportedly built around 20,000 humanoids in 2025 and more than 40,000 in the first half of 2026 alone. The West spent a decade outsourcing supply chains to look asset-light on a spreadsheet. The bill for that is arriving as a Chinese conglomerate that owns every layer of the stack and can therefore build the next labour-replacing machine cheaper than the people who invented the pitch. The robot waving at you in the showroom is not the story. The building it came out of is.
Did you know: China reportedly produced more humanoid robots in the first six months of 2026 (over 40,000) than in all of 2025 (around 20,000), doubling a year’s output in half the time.
