Modular, high-performance large robots. Payloads from 400 kg to 620 kg. The large robot series, with new members added, offers significant performance advantages, including energy savings of up to 30%. IRB 7710 and IRB 7720 place greater emphasis on efficient modular design, saving up to 30 %1 of energy consumption while delivering world-leading equipment performance and quality. The series offers 16 variants, with robot payloads of 280-620 kg, meeting customers' needs for greater flexibility and sustainable production. Want to learn more about the new large robots? The automotive industry has existed for more than a century, driving profound technological and social change. We are seeing more and more automotive manufacturers shift from internal combustion engine (ICE) manufacturing to electric vehicle (EV) manufacturing. The transition to electric vehicle powertrains requires a fundamental change in how cars are produced, bringing new challenges to automotive manufacturers, including the need to equip workers with new skills and maximize sustainability at every stage of production. To address these challenges, the industry needs to act quickly to become more adaptable and make greater use of automation and robotics. With its global reach, advanced solutions, and more than 40 years of automotive automation project experience, ABB is the ideal partner to help you achieve faster, more resilient, and more efficient automotive production. The robots can still deliver best-in-class motion control at speeds of up to 1600 mm/s, with path accuracy
