In 2000, KUKA Schweißanlagen GmbH and KUKA Roboter GmbH together with several suppliers of automation equipment formed the KUKA control web initiative. The goal of this initiative is to develop an alternative control concept for automotive body shop applications characterized by higher functionality and improved cost to function relationship. With a prototype system for car door production, running since 2001, the PC- and internet based technology is tested in practice. This paper provides an overview about the technology, the experiences and the future targets.
