Rainbow Robotics Collaborative Robots
Rainbow Robotics Collaborative Robots · RB Series
Rainbow Robotics is a Korean collaborative-robot specialist that develops and vertically integrates the core cobot components in-house — actuators, encoders, brakes, and controllers. Its flagship RB series comprises six models with 3–20 kg payloads and ±0.05 mm repeatability, and features Android-tablet-based teaching, plug-and-play expansion for grippers and sensors, and global safety certification (TÜV SÜD).
