Because robots can perform certain basic tasks more quickly and accurately than humans they are being increasingly used in various manufacturing industries. In order for most of the larger manufacturing industries, such as the automotive industry, to remain competitive it has been necessary for them to introduce robots on quite a large scale. Robots are now used extensively for such operations as spot and seam welding, assembling components, moving heavy parts, spray painting, and repetitive machining operations. In order for a robot to perform these tasks it must be programmed by a minicomputer, which will not only direct the robot to perform the required steps but will also “remember” the sequence. Information is fed by the operator (or programmer) into a control unit consisting of the minicomputer and a cathode ray tube (CRT) or video display. The operator can, at any time, edit a previous program by deleting or adding any desired steps.
