BYD Publishes the Face of Its First Self-Developed Humanoid in a Design Patent, Not a Launch Event

BYD's first self-developed humanoid robot has appeared in full public view — not at a launch event, but in a design patent. China's National Intellectual Property Administration published the filing on October 9, two days after it was granted, under the product name "embodied AI robot," with BYD Co. listed as the owner and publication number CN310247768S.

The eight drawings show a black-and-white machine with a rounded, screenless head and no attempt at human facial features. Shoulders, elbows, hips and knees are rendered as black spherical or hinged joints against a white shell. The stated uses cover walking, balance and environmental interaction, in service, education and industrial settings.

BYD has not confirmed that the patent depicts the final production model, but the proportions closely match "Xiao Di," the humanoid the company teased on July 28 through a silhouette poster posted by executive vice president He Zhiqi. Previously reported company figures put Xiao Di at 1.61 meters and 58.5 kilograms, with 31 degrees of freedom and a dexterous hand whose repeat positioning accuracy reaches plus or minus 1 millimeter — enough for grasping objects, gesture interaction and pointing-based explanations on a showroom floor.

The paper trail runs longer than the public statements. The design application was filed on April 30, weeks before any executive would confirm the program existed. Executive vice president Li Ke first acknowledged in an interview in early June that BYD was developing a humanoid, and in August Xiao Di made its first public appearance in the flesh at the company's Di Space venue in Zhengzhou, where it has been running in regular service since.

The economics are the part BYD keeps returning to. According to figures the company has previously disclosed — and has not independently verified — more than 80 percent of the robot's core components are developed in house and over 60 percent are shared with the automaker's existing parts portfolio: servo motors drawn from FinDreams powertrain capacity, battery and BMS systems taken from the Blade battery stack. The company has also said the robot runs BYDRobotOS 1.0, which ports the driving-domain controller algorithms from its vehicles, with end-to-end latency under 50 milliseconds.

The deployment plan is equally unromantic. BYD intends to put the robots to work first in its own factories on high-intensity repetitive tasks, then in showrooms, with a target of two to three units per dealership for greeting customers and explaining vehicles. The company's robotics footprint already includes a dedicated embodied AI team formed in 2022, an investment in Agibot in August 2023, a stake in tactile sensor maker PaXini taken in April 2025, and a Changsha plant that hosted UBTECH's Walker S1 for materials handling trials.

A design patent is the cheapest possible product reveal: no specifications to defend, no price to justify, and an industry that will count the joints for free. It also fits the pattern of a company that prefers to let hardware age in public before committing to a roadmap. What is still missing is everything that matters commercially — a production timetable, a price, and evidence that a humanoid assembled from car parts can hold up outside a showroom.
