Practical industrial low cost vision for welding robots and automated welding machines

The potential benefits of equipping arc wielding robots with vision to provide adaptive control for seam tracking have been widely accepted. A limited survey of industrial users' requirements suggested a more robust and cost effective solution was needed. This chapter describes continuing work at UMIST to build a practical industrial device to meet this requirement, based on earlier work using a single linescan, and avoiding the use of laser illumination .
