BYD has inadvertently offered a detailed look into its nascent humanoid robotics ambitions after an early social media post from a company experience center was published and swiftly taken down. Discussions on domestic platforms have since corroborated specifics of the project, which BYD is calling “Xiao Di.”
Dimensions, precision, and perception
The leaked specifications describe a robot standing 5 feet 3 inches tall and weighing 130 lbs. Its mechanical design incorporates 31 degrees of freedom spanning the hands, legs, torso, and neck, enabling fluid and precise motion. The hands are capable of gripping objects up to 2.2 pounds with an accuracy of 0.04 inches. Xiao Di perceives its environment through 360-degree vision combined with dynamic real-time 3D modeling, allowing it to recognize complex objects, faces, gestures, and lip movements. A multimodal interaction system supports real-time translation across six dialects and six foreign languages.
A familiar face for showrooms and factories
The name Xiao Di plays on the Chinese word for “small” and BYD’s own brand shorthand, roughly translating to “little BYD.” Internal references describe the robot as female, a characterization that aligns with the company’s broader commercial strategy. Executive Vice President Stella Li has previously remarked that BYD dealerships could eventually host two or three humanoid robots each, serving as sales assistants that greet visitors, explain electric vehicle features, and conduct demonstrations.
An intensifying robotics race in China
Xiao Di’s development places BYD in a growing field of Chinese automakers expanding into humanoid robotics. Chery is already offering its Aimoga robots, while SAIC-GM deploys wheeled robotic units on factory floors. BYD intends to use Xiao Di both in its own manufacturing operations and across hundreds of showrooms. With a prototype reportedly scheduled for a public debut in August, Xiao Di could escalate the competition with systems such as Tesla’s Optimus and Xpeng’s Iron, both of which are advancing toward mass production.
