An automation system will include different components, in addition to the robot, to provide the complete solution. This chapter provides an introduction to some of the most frequently used technologies, including handling and feeding systems, vision, grippers and tool changers, as well as tooling and fixtures. The process equipment required for a robot application is discussed, particularly for welding, painting, dispensing, and material removal applications. Assembly automation is also reviewed. The basic requirements for the system control, including networks and human machine interfaces, are introduced together with the basic principles of safety and guarding for automation systems.
