BXI Robotics
BXI Robotics (半醒科技) is a Shanghai humanoid robot company that designs its own joint motors, control electronics and complete humanoids, and builds robots for other brands as an ODM partner. It was founded in 2022 in Huangpu, Shanghai, and manufactures in Shenzhen. Its technology stack includes hollow-shaft planetary joint motors, a PCIe-CAN control architecture, the Elf series of humanoids and an UpperBody dual-arm teleoperation platform, and it says brand customers can own a custom high-performance humanoid within three to six months. The current Elf 3 is a 1.45 m general-purpose humanoid with 31 degrees of freedom, a top speed of 5 m/s, and a ROS 2 SDK with MuJoCo simulation for research and education. An unmodified BXI Elf 2 finished sixth in the first Beijing humanoid half marathon in April 2025. BXI raised its first institutional round from listed company Feirongda in 2025 and a further round of tens of millions of yuan from Suochen Technology in 2026.
💡Notable Achievement: Manufacturing in Shenzhen and Changzhou; targets scaling from tens to about 100 units a month.
