Rb Y1

Overview

The Rainbow Robotics RB-Y1 is a wheeled dual-arm humanoid from South Korea's leading humanoid developer, available for purchase at $80,000 to $120,000. Rainbow Robotics has a strong track record in collaborative robot arms before entering the humanoid segment. The RB-Y1's wheeled base makes it more practical for immediate deployment in flat-floor environments than comparable bipedal competitors, with dual-arm manipulation as its core capability.

Key Specifications

The RB-Y1 uses a wheeled mobile base with a dual-arm upper body. Pricing spans $80,000 to $120,000 depending on configuration. The platform integrates Rainbow Robotics' established collaborative arm technology into a mobile humanoid form factor, giving it strong manipulation credentials. Detailed arm payload and sensor specifications are available in Rainbow Robotics' commercial documentation.

Use Cases

Laboratory automation, manufacturing assembly support, and service environments requiring both mobility and bimanual manipulation are the primary use cases. South Korean manufacturing clients have been early adopters. UK research institutions and advanced manufacturing companies are natural customers, and Rainbow Robotics has European distribution relationships to support UK enquiries.

Buying Used

At $80,000 to $120,000, the RB-Y1 has a realistic secondary market as early adopters upgrade or exit programmes. Rainbow Robotics' track record as an established cobot company provides better parts and support continuity than many humanoid startups, making used RB-Y1 units a relatively lower-risk acquisition compared to pre-production platforms. Battery cycle history and joint wear are primary inspection points.

Alternatives to Consider

Direct competitors in the wheeled dual-arm humanoid category include the Unitree H2 at $29,900, the Pollen Robotics Reachy 2 at $70,000, and various PAL Robotics platforms. For buyers willing to accept a bipedal platform, the Fourier GR-2 and UBTECH Walker S2 are relevant full-size comparisons. Rainbow Robotics has an established European sales presence, and UK buyers should be able to engage with a UK-based distributor or systems integrator for the RB-Y1, which reduces the procurement complexity compared to platforms that require direct manufacturer engagement with China or North America.
