<strong>Cyber</strong> <strong>Physical</strong> <strong>Systems</strong> – <strong>Situation</strong> <strong>Analysis</strong>DRAFT – March 9, 2012Table 2. Evolving CPS Landscape in Manufacturing 37CPS inmanufacturingCPS inmaterialsCurrentComputer-controlled machinetools and equipment; robotsperforming repetitive tasks,fenced off from peopleRelatively few, highlyspecialized applications ofsmart materials—predominantly passivematerials and structuresFutureSmarter, more connected processes for agile andefficient production, manufacturing robotics thatwork safely with people in shared spaces,computer-guided printing or casting of compositesElectronics provide versatility without recourse toa silicon foundry; emerging materials such ascarbon fiber and polymers offer the potential tocombine capability for electrical and/or opticalfunctionality with important physical properties(strength, durability, disposability)The state of robotics in today‘s manufacturing industry as designed to be precise and repeatable, operatein only structured environments, and have limited application. Integration of robotics is expensive, andcan cost five to ten times the capital cost. In some cases, robotic systems in factories are unsafe for peopleto be around, leading to a separation between the two types of workers. 33Table 2 shows the current and future vision of CPS in manufacturing and in materials.One possible application of smart manufacturing that shows a shift towards the production ofcustomizable, more accessible manufacturing is the development of three-dimensional (3D) printing andadditive manufacturing. A 3D printer creates objects by taking a digital file and then deposits layers ofmaterial until the object is completed. Today, there are 3D printers that are used to make prototypesduring the design process, or even production of small amounts of products. One of the benefits of 3Dprinting is the idea of additive manufacturing or that the product is created using only the material that isneeded. Also possible is the ability to easily make repairs on-site. 34 Reduction in the amount of materialused can help to reduce costs, waste, and weight, while still maintaining quality. Although these printersare not extensively used in traditional manufacturing environments because of cost and time restraintsamong others, there is the possibility of these types of machines being integrated into manufacturingsystems. 35 A 3D printer that is marketed towards consumer use will soon be available for purchase, whereobjects can be created from scratch or customized from existing designs and then sent to the printer. Alsoavailable is a platform where applications or designs for products can be purchased or sold. 36There is a current trend in today‘s manufacturing towards ―converged modular automation,‖ in whichsystems are built of modular cyber-physical components. These components have their own embeddedcontroller and are all connected by a network that allows for a supervisory controller to gatherinformation and for information exchange from peer-to-peer. 38 The advantage of such modular33 Rodney.
