The Rainbow Robotics RB-Y1 is listed at $120,000 for a new unit, as per distributor pricing in early 2026. Used units are not yet available as the robot is still in early commercial release. Contact Rainbow Robotics or authorized resellers for current quotes and possible volume discounts.
The RB-Y1 is a mobile dual-arm robot that can navigate indoor spaces and perform light manipulation tasks such as pick-and-place, assembly, and inspection. With 24 DOF and an AI-driven planning system, it can adapt to new tasks through voice or text commands. Its omnidirectional Mecanum wheels allow it to move in any direction at up to 5.4 km/h.
Yes, the RB-Y1 is available for pre-order as of 2026. Authorized distributors in Korea and select regions are accepting orders, with estimated lead times of 8–12 weeks. It is not sold directly through retail channels; interested buyers must contact Rainbow Robotics or its partners.
The RB-Y1 offers dual arms at $120,000 versus the KMR iiwa’s single arm at $170,000. However, the KUKA system provides industrial-grade reliability, 7 kg payload per arm, and safety certifications for direct human collaboration. The RB-Y1 is more affordable and has a humanoid-like torso, but the KUKA is suited for heavy, precise tasks.
Height: 161 cm, Weight: 131 kg, Degrees of freedom: 24, Max speed: 5.4 km/h, Battery life: 3 hours, Arm payload: 3 kg per arm. It features an omnidirectional Mecanum wheel base and dual 7-DOF arms.
The RB-Y1 is manufactured by Rainbow Robotics, a South Korean company founded in 2011 and headquartered in Daejeon. The company specializes in collaborative robots and is known for its RB series of cobots.
The RB-Y1’s battery lasts approximately 3 hours under typical operation. Charging time is not publicly specified. The battery is integrated and not hot-swappable; downtime for recharging is required.
Primary adopters are research institutes and manufacturing pilot programs in automotive, electronics, and logistics. In South Korea, some companies are testing it for AI-driven human-robot collaboration in small-parts assembly and intralogistics.
Safety certifications for the RB-Y1 have not been announced. While its wheeled base removes fall risks of legged robots, it lacks published data on collision detection or force-limited joints. Operators should use additional safety sensors and barriers until certified for collaborative use.
Rainbow Robotics has not disclosed specific sensor models or compute platform. Sources suggest it includes depth cameras and lidar for navigation, but details remain unverified. The robot is marketed as AI-capable, implying onboard GPU or AI accelerator, but specifications are not public.
