Rainbow Robotics

Advanced

A Korean company founded by KAIST's humanoid HUBO team, under Samsung's control since 2025.

Rainbow Robotics was founded in February 2011 and is headquartered in Daejeon, South Korea. Founder Jun-ho Oh is a professor at KAIST's Humanoid Robot Research Center and led development of the bipedal humanoid HUBO; its DRC-HUBO won the 2015 DARPA Robotics Challenge. The company later commercialized its joint and control technology: the RB series of collaborative robots (arms that can work alongside people in the same space), quadruped robots, and, released in 2024, the wheeled dual-arm humanoid RB-Y1, which overseas labs often use as a platform for collecting demonstration data and training VLA models. The company is listed on the Korea Exchange (ticker 277810); Samsung Electronics reportedly announced in late 2024 that it would raise its stake to about 35%, becoming the largest shareholder after regulatory approval in March 2025.

ExampleRB-Y1 uses a wheeled base plus two 7-degree-of-freedom arms, sidestepping bipedal balance issues, which makes it well suited to mobile-manipulation research.
