A design patent published on October 9, 2026 revealed BYD's first self-developed humanoid, the 1.61-meter Xiao Di with 31 degrees of freedom. The company plans to deploy the robots first in car dealerships for greeting and demo duties, then on factory assembly lines.

China's National Intellectual Property Administration published a design patent on October 9, 2026 that shows BYD's first in-house humanoid from four angles. The drawings reveal an oval, screen-free head, a light-paneled torso and fully articulated arms down to the fingers, a clear carry-over of the brand's automotive design language. The crucial caveat, underlined by CnEVPost, is that the filing protects looks only; it promises nothing about production schedules, cost or field performance. Robothot's summary of the filing describes a machine built for walking, balance and interaction, an embodied-intelligence product aimed at industrial, educational and service settings.

What the Patent Shows, and What It Does Not

The headline numbers are crisp: 1.61 meters tall, 58.5 kilograms, 31 degrees of freedom , seven of them in the hands. According to the compilation by InterestingEngineering, the robot translates in real time across six Chinese dialects and six foreign languages, and pairs face and gesture recognition with lip-reading. Panoramic 360-degree vision plus dynamic modeling of complex objects is what lets it roam a crowded showroom without getting lost. One detail stays in the unverified column for now: the claim that its hands lift up to one kilogram.

The name and the stage came into focus over the summer: the robot, called Xiao Di, was presented in August at the Di Space experience center in Zhengzhou, following a company confirmation carried by the Chinese press in late July. CnEVPost reports the August debut was officially confirmed, while stressing that the patent drawings may or may not match the final product. The original CarNewsChina report strikes the same cautious note: the document is a statement of intent, not a factory order.

A Robotics Base Built Since 2022

This is no overnight pivot. BYD started its physical-AI program with a dedicated team in 2022, building sensing, decision and actuation software in-house. Outside, it bought into the ecosystem early: according to Wikipedia, Shanghai-based Agibot counted BYD among its backers in August 2023 before closing an oversubscribed round later that year. Agibot's first humanoid, the RAISE A1, offered 49 degrees of freedom for bolt-tightening and vehicle inspection. The picture is a company feeding its robot from both ends, a homegrown stack below and a venture ecosystem above.

On the factory side, BYD rehearsed with other vendors' hardware while its own machine matured. EyeShenzhen reports that Ubtech's industrial Walker S1 joined material-handling and parts-recognition training at the Changsha plant, described on Ubtech's solutions page as the first coordinated deployment of humanoids with autonomous logistics vehicles. By using its own factory as a proving ground , BYD banked operational data long before Xiao Di touches an assembly line.

Dealerships First, Assembly Lines Next

The most interesting link in the roadmap is the commercial order: dealerships first. The robots will greet visitors, explain trim levels and demo infotainment systems, with two or three units per store and commercial scale targeted within a year or two, as reported by InterestingEngineering. Factory assembly lines come in the second wave. That retail-first strategy is a deliberate break from the factory-first playbook of Tesla- and Figure-style rivals.

The 2026 scoreboard is crowded. Per IIoT World, the thousand-plus Optimus units at Tesla's Fremont site run primarily for learning and data collection by the company's own account, with no external sales or uptime figures disclosed. Technology.org's July analysis puts Figure and Agility ahead on verified deployments, citing BMW's Figure 02 pilot at Spartanburg and the follow-on Figure 03 logistics project as the concrete example. Xpeng's Iron targeting four-digit monthly output and 2027 showroom rollout shows Chinese rivals entering the same retail corridor. BYD's trump card in that crowd is obvious: a giant dealer network that doubles as a ready-made distribution channel .
