Assembly processes that previously employed conventional methods of human labour are changing now. Complicated and repetitive procedures are now being taken over by automated robotic systems that result in more efficient completion of tasks and reduce the amount of time taken. The credit for this positive change goes to extensive technological advancement over the past few decades. The robots feature motion guidance by 2D and 3D vision systems that enable these robots to locate specific parts that have to be assembled or to identify the specific style required for the assembly process.
