As robotic technology gains prominence as a key driver of the Fourth Industrial Revolution, Rainbow Robotics is leading the global robotics industry with its unparalleled technological prowess and innovative products. Since its establishment in 2011 by researchers from KAIST's Hubo Lab, the company has driven the commercialization of robot technology by introducing various robot platforms based on its experience in developing Korea's first bipedal robot, 'Hubo'. In particular, through a recent strategic partnership with Samsung Electronics, Rainbow Robotics is rapidly evolving beyond a simple robot manufacturer into a platform company that sets the standard for the future robotics industry. Rainbow Robotics is opening new frontiers in robot technology through continuous research and development to realize a future society where humans and robots coexist.
One of Rainbow Robotics' greatest strengths is its ability to develop and internalize core robot components through its own technology. By directly designing and producing key components that determine robot performance, such as motors, reducers, controllers, actuators, encoders, and brakes, the company has secured high price competitiveness and flexible product responsiveness. This internalization of components maximizes the precision and stability of the robots, forming the basis for providing optimized robot solutions tailored to diverse customer needs. Furthermore, the company has developed its own Linux-based real-time robot operating system, which efficiently manages robot performance and supports predictable task execution. This technological self-reliance serves as a powerful driving force for Rainbow Robotics to achieve continuous innovation in the rapidly changing robotics market.
Rainbow Robotics is making significant strides in the field of collaborative robots (Cobots), which work safely and cooperatively with humans in the same space. The RB series collaborative robots feature a 6-axis robot arm equipped with a collision detection system, gravity compensation device, and sophisticated motor control system, making them suitable for various industrial environments. In particular, the NSF-certified collaborative robot RB-N series, designed for the Food & Beverage (F&B) industry, demonstrates outstanding performance even in environments where hygiene and safety are critical. Rainbow Robotics' collaborative robots are designed with user-friendliness in mind, featuring intuitive software and simple operation, allowing non-robot experts to easily adopt and utilize them in manufacturing and service industries. These are recognized as innovative solutions that maximize production efficiency and reduce the burden on workers. Detailed product information can be found on the Rainbow Robotics official website.
Building on its experience in developing 'Hubo', the bipedal robot symbolizing Korea's robot technology, Rainbow Robotics has earned recognition for its technological capabilities by supplying research platforms to leading research institutions worldwide. Furthermore, the company has expanded its focus to quadrupedal robots, the core of future robotics, with the 'RBQ series'. The RBQ series is an AI-based, high-mobility quadrupedal robot platform capable of stable movement even on rough and uneven terrain. Its ability to flexibly switch between dynamics-based walking and reinforcement learning-based AI walking according to the situation achieves both precise control and robust locomotion. Environment perception and autonomous driving technologies utilizing 3D LiDAR, Depth cameras, and PTZ cameras enable various functions such as obstacle avoidance, slope and stair climbing, and autonomous return charging. Recognizing this innovative technology, the RBQ series was selected as one of the 'Top 10 Mechanical Technologies of the Year 2025' in Korea.
In late 2024, Samsung Electronics secured majority shareholder status in Rainbow Robotics, marking a new turning point in the strategic partnership between the two companies. Samsung Electronics increased its stake in Rainbow Robotics to 35.0% and has the option to further increase its stake to up to 59% through future call options. This collaboration is a key driver accelerating the development of intelligent, advanced humanoid robots by combining Samsung's AI and software technologies with Rainbow Robotics' robot hardware technology. Samsung Electronics plans to actively utilize Rainbow Robotics' robots for automating tasks within its group, including manufacturing and logistics, while Rainbow Robotics is accelerating its overseas market expansion through Samsung's global sales infrastructure. This synergy is expected to play a crucial role in Rainbow Robotics securing strong competitiveness and emerging as a leader in the global robotics market.
Rainbow Robotics is focusing on developing more intelligent and autonomous robot solutions by integrating artificial intelligence (AI) with robot technology. Through a recent collaboration with AI solutions company Flowise, the company has demonstrated an automated assembly solution for automotive headlamps using a dual-arm robot, thereby strengthening its capability to perform complex AI-based tasks. The mobile dual-arm robot 'RB-Y1' is an optimized platform for AI developers and researchers, offering omnidirectional movement based on a mecanum wheel system and an open software development kit (SDK) to enable the implementation of various AI technologies. This platform is actively being adopted as a research platform by leading universities such as MIT, UC Berkeley, and Stanford, as well as research labs of global companies like Amazon and Microsoft. Through the development of 'Physical AI' robots, Rainbow Robotics contributes to strengthening social safety nets and advancing industrial automation, creating a future where robots become companions that enrich human lives beyond mere tools.
With its diversified product lineup including collaborative robots, bipedal robots, quadrupedal robots, and mobile dual-arm robots, coupled with its core component in-house development capabilities and strong strategic collaboration with Samsung Electronics, Rainbow Robotics has established an unparalleled position in the global robotics market. Particularly with the full-scale commercialization of humanoid robots expected from 2026, Rainbow Robotics is highly likely to become a key supplier in the humanoid robot ecosystem. Transitioning from a simple robot vendor to a system-centric business structure, the company is emerging as a new growth axis amidst the evolving robotics industry. The company's future endeavors, driven by next-generation robot technologies combined with AI, are expected to lead innovation across various fields such as manufacturing, logistics, service, and healthcare. Further details on the in-house development of robot components can be found in the ZDNet Korea article.
