Overview
The RB3-1200 is a collaborative/industrial robotic arm platform developed by Rainbow Robotics. The source indicates the Rainbow Robotics product page title is “RB3-1200 | 레인보우로보틱스”. The RB3-1200 is a 6-axis industrial collaborative robotic arm in the RB series from Rainbow Robotics (South Korea). Its model designation indicates a rated payload of 3 kg and a maximum reach of 1200 mm. The unit weighs approximately 22 kg and achieves a repeatability of ±0.05 mm. Each joint is equipped with proprietary precision harmonic drives and frameless torque motors, featuring a long reach, lightweight structure, and collision detection safety functions.
This model supports graphical programming and ROS/ROS 2 development interfaces, and is suitable for applications requiring large workspace and light-payload human-robot collaboration, such as electronics assembly, machine tending, automated inspection, commercial services, and research and education. Core hardware specifications include: 6 DoF, weight 22.0 kg, and rated payload 3.0 kg.
Regarding perception, computing, and system integration, the model features high-precision absolute encoders at each joint and current/torque feedback loops. Onboard computing utilizes a real-time industrial control cabinet / ROS 2 host interface, covering L1-level technology. Development and selection teams can evaluate its motion envelope, payload limits, and secondary development compatibility for target applications using official documentation, motion control interfaces, and simulation assets (URDF/MJCF).
