Collaborative robots, or cobots, are compact robotic systems designed to collaborate with humans in various industrial tasks such as welding, product inspection, dispensation, and conveyance within factory settings. Despite being engineered for challenging environments, certain crucial cobot components, such as arms, are prone to damage due to extreme environmental factors and operational conditions. As the adoption of cobots has steadily increased in recent years, Nabell identified the need for protective covers to shield robot arms from environmental elements that could compromise their performance and longevity. Consequently, we have introduced the NRF Series of our Robot-Flex suits, specifically tailored for collaborative robots, including those of the UNIVERSAL ROBOT brand. These cobot suits are meticulously crafted to ensure an optimal range of motion for each cobot model, thereby extending the lifespan of the covers. The suits seamlessly integrate traditional processing techniques with cutting-edge 3D printing technologies.
