SUMMARY:

 

RB‑Y1 is Korea’s first bimanual mobile manipulator, developed by Rainbow Robotics, the company behind the HUBO humanoid line.  

 

It mounts a humanoid‑type dual‑arm system (7 DOF per arm) onto a high‑speed wheeled base, combined with a 6‑DOF single leg that adjusts body height and center of gravity.  

 

The robot supports real‑time teleoperation, AI‑based learning, LiDAR navigation, and is sold as a research platform for advanced robotics and embodied‑AI development. 

 

EDITORIAL:

 

RB‑Y1 is not a walking humanoid — it is a hybrid humanoid‑manipulator platform designed for industrial‑grade manipulation + mobile autonomy.  

 

Rainbow Robotics built it using the same actuators and components found in their collaborative robots and AMRs, giving it industrial reliability. 

 

The robot’s defining feature is its 22‑axis whole‑body control (excluding wheels), enabling:

 

- coordinated dual‑arm manipulation  

- dynamic high‑speed driving  

- sudden acceleration and turning  

- safe center‑of‑gravity control via the 6‑DOF leg  

 

It can also be taught by demonstration using a master–slave data arm, with built‑in self‑collision avoidance and a simulation environment for AI training. 

 

RB‑Y1 is positioned as the first commercially available AI‑research humanoid platform, priced far below full humanoids while offering advanced manipulation and mobility.
