China's AI company AI2 Robotics and XSquare Robot have each raised investment after being valued at more than 50 billion yuan, or about $2.8 billion, SiliconANGLE reported on Sunday, citing Bloomberg.

AI2 Robotics raised about $735 million in the funding round, the report said. The size of the investment raised by XSquare Robot was not disclosed.

AI2 Robotics, headquartered in Shenzhen, develops general-purpose intelligent robots. It also develops its own vision-language-action, or VLA, model that provides spatial reasoning and intelligence that lets robots see, understand the world and act without manual control.

Its flagship products are the Alphabot series of wheeled humanoid robots. The Alphabot series runs on AI2 Robotics' in-house foundation model called Alpha Brain, and interprets complex commands, manipulates objects and carries out goal-based tasks.

XSquare Robot is known for its in-house frontier robotics model called WaiAI and its Quanta series of wheeled humanoids. In September 2025, it released an open-source version of the model, Wai-OSS, to promote community-led development. It is developing its own data-collection tools, including remote control, exoskeletons and a dedicated interface for understanding human movement, to improve robot performance.

Quanta robots have been deployed in a range of settings, from household work to industrial logistics. XSquare Robot's core goal is to supply general-purpose humanoid robots to sectors facing labour shortages or requiring repetitive physical work. It is targeting both the home services market and the industrial market for precision factory assembly and materials transport.
