Canonical robot record
Overview
The Rb Y1 is Rainbow Robotics' bimanual mobile manipulator, mounting a humanoid-style dual-arm upper body on a wheel-type high-speed mobile base so it can operate across varied environments. The design pairs precise two-arm manipulation with rapid, agile movement, and a multi-axis torso lets the robot change its working height to reach tasks at different levels.
Rainbow Robotics describes the Rb Y1 as a platform aimed at AI and robotics researchers, with a separate commercial variant, and the company has highlighted it as Korea's first bimanual mobile manipulator. It builds on the company's heritage developing the HUBO humanoid robots.
The platform supports teaching-by-demonstration workflows, where an operator guides the robot's arms to train tasks, and includes safeguards such as self-collision prevention. Rainbow Robotics opened pre-orders for the Rb Y1 in 2024.
