Rainbow Robotics History

Rainbow Robotics' roots go to the early 2000s at KAIST, where Professor Oh Jun-ho developed the HUBO series. In 2011, Oh formally founded Rainbow Robotics as a KAIST spinoff.

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.
