About RB-Y1
The Rainbow Robotics RB-Y1 is South Korea's first commercially available bimanual mobile manipulator, developed by a KAIST robotics spinoff now majority-owned by Samsung Electronics. Standing 140 cm tall on an omnidirectional Mecanum wheel base, the RB-Y1 pairs dual 7-DOF arms with a unique 6-DOF torso that provides over 50 cm of height adjustment for versatile manipulation tasks. Powered by an NVIDIA Jetson AGX Orin and a 1,270 Wh battery pack, it delivers 3-4 hours of continuous operation at speeds up to 1.5 m/s. The platform is already deployed at Samsung Display for precision lens replacement and at CJ Logistics for warehouse picking and sorting. Research groups at MIT, UC Berkeley, and Georgia Tech have adopted the RB-Y1 as a research platform. Priced from $80,000, it targets the gap between industrial cobots and full humanoids.
Made by Rainbow Robotics
South Korean humanoid robotics company with $5.8B market cap. Samsung holds 35% stake. Winners of DARPA Robotics Challenge. RB-Y1 is their flagship full-size humanoid platform targeting industrial applications.
