Asea's IRB6: The First Fully Electric Industrial Robot and Its Market Impact

In 1974, Asea introduced the IRB6 S1, the world's first fully electric industrial robot, later becoming a pioneer in robotics. A total of 1,900 units were produced between 1975 and 1992. The robot, capable of handling six-kilogram loads with five axes, was utilized in various applications, including arc welding. Collaborations with companies like BMW and Daimler facilitated its adoption in the automotive industry, despite initial resistance to automation. Asea's focus on hydraulic robots ultimately led to its decline in the face of electric robot demand, resulting in Unimation's acquisition by Westinghouse in 1982.
