277810 Company Profile

Rainbow Robotics grew out of a Korean university lab that built the country's first humanoid walking robot, and it now sells collaborative robot arms and mobile platforms. Samsung Electronics became its largest shareholder, tying the company to Samsung's push into robotics and factory automation. That backing makes it the listed Korean name most closely associated with humanoid robot development. US investors following the humanoid theme use it as a Korean comparison to Western robotics startups that are not publicly traded.
