Dürr EcoRS Generation 2 Paint Shop Robots

Dürr has launched the EcoRS Generation 2 series, providing a unified robotic platform specifically engineered for automotive manufacturing facilities. The hardware automates fine-seam sealing, surface cleaning, and material handling processes within the rigorous environmental conditions of industrial paint shops.

Engineering Challenges in Paint Shop Automation
Automotive paint shops present highly specialized environments where robotic systems must endure continuous exposure to chemicals, overspray, and intensive cleaning protocols while maintaining extreme path accuracy. Conventional automation approaches often rely on fragmented hardware and software architectures for different tasks, such as fine-seam sealing versus heavy material handling. This fragmentation increases the complexity of system planning, expands spare parts inventories, and complicates integration and service processes across the equipment's operational lifespan.

Kinematic Architecture and Interference Contour Reduction
To address spatial constraints and improve cleanability, the EcoRS Generation 2 incorporates internal motors for axes three through six alongside fully internal cabling. This internal routing significantly reduces the robot's interference contour, minimizing the risk of snagging or contamination in restricted work envelopes. The optimization of the mechanical design also yields a reduction in the overall space requirements and physical weight of the units compared to conventional solutions. The series encompasses four distinct models, providing payload capacities ranging from 20 to 150 kg and maximum reach distances of up to 3,100 mm. This enlarged work envelope accommodates different vehicle models and provides flexibility for future production programs.




Process Integration and Unified Control System
Unlike generic industrial robotic arms, the EcoRS series was developed with close integration between the robot kinematics, control unit, and application process technology. This synchronization enables high path accuracy and consistent material deposition, which is critical for achieving reproducible and high-quality results in fine-seam sealing applications on modern vehicle bodies. Martin Wurst, Product Manager at Dürr, explains the technical positioning: "With the new EcoRS generation, we are establishing a standardized platform for sealing applications." Operating on a unified control and software architecture, the platform utilizes the same control technology found in Dürr’s existing painting robotics. The system is fully integrated into the standard Dürr control architecture and the DXQ software platform, establishing a seamless data and command landscape from a single source within the facility.




Additional Context

Within the specialized market of automotive paint shop robotics, the Dürr EcoRS Generation 2 competes with specialized sealing and handling robots such as the FANUC Paint Mate series or the Yaskawa Motoman EP and MP lines. While standard industrial handling robots often require external protective jackets or secondary routing for application hoses, Dürr’s integration of internal motors on axes three through six directly mirrors the hollow-arm architectures typically reserved for pure painting robots. By expanding this clean-design philosophy to heavy-duty sealing and handling tasks (accommodating up to 150 kg payloads) and running it on the proprietary DXQ software platform, Dürr allows automotive OEMs to unify their control logic across both the painting and sealing zones. This eliminates the need to cross-train technicians on separate PLC interfaces for different robotic brands within the same production line.
