Epson Launches Innovative C-B Series Six-Axis Robots
Collaborative robot arms often face skepticism regarding their precision and durability when compared to traditional industrial robots. Epson Robots has sought to challenge this perception with its latest C-B series of six-axis robots, which are equipped with the RC700E controller and integrated SafeSense technology, enhancing their functionality in various industrial applications.
Headquartered in Los Alamitos, California, Epson has unveiled several models in the C-B series, including the C4B, C4LB, C8LB, C8XLB, and C12XLB, all of which emphasize flexibility, efficiency, and precise performance suitable for a wide array of industrial settings.
Scott Marsic, group product manager at Epson Robots, highlighted that the enhancements in the C-B series stem from the innovative features previously found in the company’s high-end GX-Series SCARA robots. He emphasized that this series is developed to fulfill the complex automation and safety requirements of modern workplaces, showcasing Epson’s dedication to advancing industrial automation with state-of-the-art solutions.
With a strong position in the market, Epson claims to be the world’s leading manufacturer of SCARA robots, leveraging four decades of expertise to inform the development of the C-B series. The company has implemented a common PC-based platform, successfully deploying over 150,000 robots for tasks such as assembly and materials handling.
Safety Innovations with SafeSense Technology
The integration of SafeSense Technology into the new robot models allows them to operate dynamically, maintaining speed until a human employee approaches. This advancement not only boosts productivity but also enhances worker safety by minimizing the necessity for physical safety barriers, thereby reducing both the cost and footprint of the robotic systems.
James Shimano, a product manager at Epson, elaborated on how SafeSense improves the balance between performance and user interaction. He noted that industrial robots typically necessitate safety barriers that limit their operational speed; however, with SafeSense, a robot can function at full speed when unmonitored, but will reduce its speed as a worker comes closer.
SafeSense is compatible with various safety mechanisms, including pressure mats, light curtains, and lidar sensors, ensuring a versatile approach to human-robot collaboration.
The RC700E controller enhances the safety of human-robot interaction by providing continuous speed and position monitoring alongside comprehensive risk assessments. Additionally, the no-code interface of the Epson RC+ Express software allows for easy setup of “industrial collaborative workcells” that enhance reliability and repeatability in various applications.
Enhanced Development with Epson RC+ Software
According to Shimano, Epson does not solely manufacture robots for others; it also utilizes them internally for its own operations across diverse consumer products, granting them unique insights into real-world workcell challenges. The Epson RC+ development software allows users to navigate from no-code solutions to full coding capability, complete with an intuitive user interface and integrated debugging tools.
Additionally, the availability of advanced integration options—including vision guidance, parts feeding, force guidance, and conveyor tracking—positions the C-B series favorably within the Industry 4.0 framework by ensuring seamless connectivity and monitoring capabilities.
Shimano emphasizes that, rather than needing components from multiple suppliers, Epson’s integrated solutions offer a cohesive experience, functioning effectively without additional external systems. This approach allows Epson to tailor its offerings to meet specific customer goals, particularly for complex assembly tasks requiring speed, precision, and orientation.
Versatility and Performance of the C-B Series
The C-B series boasts multiple arm configurations and can handle payloads of up to 12 kg (26.4 lb), making them suitable for high-demand industrial tasks. Epson’s proprietary “SlimLine” design ensures accessibility in confined spaces, offering flexible mounting options including tabletop and ceiling, with reach specifications ranging from 600 to 1,400 mm (23.6 to 55.1 in.) depending on the model.
Furthermore, the GYROPLUS technology embedded in these robots minimizes vibrations, fostering faster cycle times and precise operations without compromising on performance. Shimano explained how GYROPLUS technology improves trajectory accuracy without the need for additional mass.
To suit a variety of environmental needs, the C-B series includes standard, cleanroom (ISO32/ESD), and IP67 models, ensuring adaptability for diverse operational requirements.
Reflecting on the evolving landscape of automation, Shimano noted that the distinctions between industrial and collaborative robots are increasingly becoming blurred, suggesting that users can now enjoy the benefits of both types. “We have been anticipating the widespread adoption of robotics for several decades, and instead of pursuing a one-size-fits-all solution, we engage with end users to develop tailored approaches,” he stated.
The C-B series robots are currently available through Epson Robots’ distributor partnerships.
