This example which does not pretend to be either the sole or the best concept of circuit assembly permits US to derive some very significant conclusions 1. Single manipulators working in concert facilitate the performance of simultaneous operations thus saving time 2. Simple manipulators are faster because their masses are smaller no complicated transmission or drives are necessary and their stiffness is greater fewer backlashes smaller dimensions 3. There are groups of devices which carry out universal tasks . hoppers magazines feeders carriers conveyors and grippers 4. There are devices or specialized manipulators which carry out some specific tasks such as assembling bending and cutting. Structure OÍ Automatic Industrial Systems It is possible to describe a generalized layout of an automatic machine almost regardless of the level of control to which it belongs. We will thus show that the building-block approach is an effective means of design of automatic machine tools. The following building blocks for devices may be used in the layout of automatic machines Feeding and loading of parts or materials blocks Functional blocks Inspection or checking blocks Discharge blocks Transporting or removing blocks. Blocks that are responsible for the feeding and loading of materials in the form of rods wires strips powders and liquids or of parts such as bolts washers nuts and special parts must also be able to handle processes such as orientation measuring and weighing. Functional devices are intended for processing namely assembling cutting plastic deformation welding soldering pressing in and gluing. Inspection or checking blocks ensure that the part being processed is the correct one and that the part is in the right position. These devices also check tools for readiness wear etc. The .
