Robots Assemble A Hummer

Kuka framing robots, manufactured by KUKA Roboter GmbH,, assemble a Hummer on the Hummer 3 line in the state-of-the-art Shreveport, Louisiana, GM assembly plant. Photographers love it when sparks pop and fly from manufacturing robotic welders. Engineers get uncomfortable with those same sparks because it means the welding tips are not perfectly aligned. Perfect alignment means no sparks and no sparks means a still photograph. I respect those engineers, but the sparks represent movement and dynamic action within a still image. If we cannot easily capture the rhythmic movements of the robot arms in a single frame, at least we can capture the beautiful explosive movement of the welding sparks. This image was made for the book, Hummer H3 (2005; Motorbooks).
