Product overview
About Rainbow Robotics RB-Y1
RB-Y1 is a wheeled dual-arm mobile manipulator from Rainbow Robotics of Sejong, South Korea, sold mainly as a research platform (s6, s1). Rainbow describes it as 'not a finished robot for a single task' but a humanoid-style mobile dual-arm platform, and as a base for next-generation robotics technologies such as AI-based manipulation learning (s1).
The product page lists a height of 1,400 mm, 3 kg of payload per arm and arm repeatability of Β±0.05 mm, with a 48 VDC power supply (s1). The developer manual gives 24 degrees of freedom for Model A and a 1,270 Wh battery (s5). A real-time robot PC is separated from a user PC that runs ROS 2 and the SDK, and a leader arm transfers an operator's motions to the robot for learning from demonstration (s1).
Rainbow opened pre-orders in May 2024 at USD 80,000 for the research platform, excluding VAT, and listed the commercial platform at USD 120,000 excluding VAT (s2). A Korean report in October 2024 said the 30 pre-order units had sold out (s4). The product page now lists no order option and directs buyers to a product inquiry form (s1).
