That is, instead of a pick and place process executed by an industrial robot, if a conveyor and a simple hydraulic/pneumatic cylinder is enough and can push a job in another direction while not harming the product, then this simple yet effective form of mechanism is a cheaper option. Similarly, for a linear welding profile on a job, if a complex mechanism in which a roller conveyor lets the part traverse on while a stationary welding gun mounted on top performs welding based on timer logic, then this is also a very effective substitute in place of a robot. Keeping in mind that such mechanisms which somewhat serve the same purpose as Special Purpose Machinery (SPM) unlike industrial robots, come at the cost of only being able to do one task throughout its product cycle.</span></span></li>
