Elsewhere, six-axis articulated arm robots ride on seventh-axis systems to execute priming, painting, clearcoating, and other sealing processes on automobile panel bodies. Such arrangements deliver flawlessly consistent results that are in part so reliable because these processes are executed in well-isolated spray booths effectively kept uncontaminated by particles from the outside environment. Six-axis robots also follow programmatically optimized spray paths for perfect finishes even while minimizing overspray and paint and sealer waste. What’s more, they eliminate the need to expose automobile-plant personnel to the harmful vapors associated with some spray-applied materials. Selective Compliance Articulated Robot Arm (SCARA) robots have two revolute joints having parallel turning axes running in the vertical direction for X-Y positioning in a single plane of motion. Then a third linear axis allows motion in the Z (up and down) direction. SCARAs are relatively low-cost options that excel in confined spaces — even while delivering faster moves than equivalent cartesian robots. No wonder SCARA robots are used in production of automotive electronics and electrical systems — including those for climate control, mobile-device connectivity, audio/visual elements,
