RB-Y1 Transforms Industrial Tasks with 360-Degree Mobility and Open-Source Development Framework

Korean Innovation Reshapes Factory Floors

Rainbow Robotics demonstrated significant advances for its RB-Y1 dual-arm manipulator at ICRA 2025, introducing an omnidirectional Mecanum wheel system and integrated software development kit that fundamentally expand the robot's operational scope. The Seoul-based firm, which emerged from KAIST's Humanoid Robot Research Center, positioned these enhancements as critical infrastructure for industrial environments where agility and customization define competitive advantage. The RB-Y1 now executes 360-degree movement in constrained warehouse aisles and manufacturing cells, eliminating the multi-point turning sequences required by conventional wheeled platforms.

Dexterity Meets Dynamic Control

The robot's dual 7-degree-of-freedom arms orchestrate complex simultaneous manipulation tasks while a single 6-DOF leg manages vertical torso adjustment exceeding 50 centimeters, enabling the system to perform pick-and-place operations at variable heights without repositioning its mobile base. This whole-body coordination framework synchronizes joint motion and force in real time, producing fluid, human-like movement patterns that reduce cycle times in repetitive assembly and station-tending workflows. The gravity compensation master arm supports teleoperation modes, allowing human operators to teach motion sequences through intuitive master-slave control while collecting interaction data for machine learning model development.

Engineering Precision at Scale

Rainbow Robotics engineered the RB-Y1 by integrating proven actuation components from its collaborative robot product line, ensuring industrial-grade durability without sacrificing responsiveness. The 20-axis full-body control system manages center-of-gravity stability during high-speed maneuvers, enabling the platform to accelerate to 5.4 kilometers per hour and execute sharp turns without toppling. Self-collision prevention algorithms safeguard the dual-arm architecture during simultaneous reaching motions, a critical reliability feature for autonomous operation in shared human-robot environments where safety margins directly impact deployment timelines.

Where Industrial Automation Accelerates

Logistics operations benefit immediately from the RB-Y1's ability to navigate narrow warehouse aisles while transporting tools and packages weighing up to 6 kilograms across both arms, effectively replacing fixed-base cobots that require dedicated floor space. Manufacturing facilities deploy the system for component kitting, where the robot retrieves parts from multiple station heights and assembles subassemblies with precision comparable to human technicians but without fatigue-related performance degradation. Research institutions leverage the open SDK architecture to prototype novel manipulation strategies, reducing development cycles for emerging autonomous applications in healthcare logistics and pharmaceutical fulfillment.

Skill Architecture & Capability Summary

The RB-Y1's 24-degree-of-freedom architecture translates into tangible interaction capabilities: dual 7-DOF arms deliver 3-kilogram per-arm lifting capacity, enabling sustained manipulation of industrial components; the 6-DOF leg supports dynamic height adjustment to maintain optimal center of gravity during acceleration up to 5.4 km/h, extending battery endurance to approximately 3 hours per charge. Integrated inertial measurement units, gripper interfaces, and LiDAR compatibility establish a sensing foundation for autonomous navigation and obstacle avoidance, transforming the 131-kilogram frame into an adaptive assistant capable of learning task variations through repeated interaction. The modular SDK architecture—compatible with ROS and Linux environments—permits engineers to rapidly integrate custom perception stacks and task policies, reducing time-to-deployment from prototype to production-floor validation.
