Rainbow Robotics introduces RB-Y1, a dual-arm mobile manipulator for research, real-world task data collection, and AI validation.
Rainbow Robotics connects RB-Y1 to its earlier humanoid work, including HUBO and the DARPA Robotics Challenge. The company positions RB-Y1 as a practical research robot for carrying out tasks and testing AI.
RB-Y1 uses in-house drives developed alongside Rainbow Robotics' RB-series cobots. With more than 20 degrees of freedom, it coordinates its arms, torso, and mobile base to reach from low areas to high shelves and work in confined spaces. The company says calibration supports accuracy during repeated tasks.
Operators can guide RB-Y1 with leader arms that mirror its joint layout or use VR from the robot's viewpoint. Position control supports precise work, while impedance control is intended for tasks involving contact. The collected data can then support AI training and evaluation.
Rainbow Robotics describes a workflow that connects data collection, model training, inference, and execution on RB-Y1. Examples include following commands, continuing after interruptions, recognizing human motion, and handing over objects. End effectors and sensors can be changed to fit different research needs.
Rainbow Robotics says universities and research labs worldwide have selected RB-Y1, with some companies testing it for industrial use. The company reports more than 150 units scheduled to ship in 2026. Its SDK and control APIs are available on GitHub, and it describes the robot as the next stage after its humanoids, cobots, and autonomous mobile robots.
