Company Story

Rainbow Robotics is a South Korean company founded in 2011 by Professor Oh Jun-ho and researchers from KAIST's Humanoid Robot Research Center, the team that won the 2015 DARPA Robotics Challenge. The company produces collaborative robots, the RB-Y1 mobile manipulator, and bipedal humanoid platforms. Samsung Electronics became its largest shareholder in 2023-2024 with a 35% stake.

History

The defining moment came in June 2015 when DRC-HUBO won the $2 million first prize at the DARPA Robotics Challenge Finals. Rainbow went public on KOSDAQ on February 3, 2021, raising 26.5 billion won.

In 2023, Samsung acquired 14.7% for KRW 86.8 billion. In December 2024, Samsung increased to 35% for a total KRW 267 billion ($181.6 million), establishing a Future Robotics Office combining Samsung's AI with Rainbow's hardware.

In 2024, Rainbow launched the RB-Y1 wheeled dual-arm manipulator, quickly adopted by MIT, UC Berkeley, University of Washington, and Georgia Tech.
