Lesson 3.1 Machine Control Note: Career Exploration – Students will continue to explore careers related to engineering and engineering technology by completing the activity Career Demand, Salary, and Education. Students will investigate further into the career field that they chose during Unit 2. Student research will be centered on facts relating to the specific career field. Students may consider career trends nationally and locally related to demand, salary, and educational training. The Career Demand, Salary, and Education activity should be completed during Unit 3 and submitted to the course instructor at the completion of Lesson 3.4.

Preface From iPods to automobiles, we use computers every day. Computers are sometimes so small and hidden that we don’t even realize we’re using a computer. Many of us never think about automobiles containing computers; however, today’s vehicles are packed with tiny computers that regulate and monitor systems such as air bags and cruise control. How much more control will computers take from drivers in the future? What will drivers be willing to let their cars do for them? With GPS systems that provide routes and track speed, what are the barriers for autonomous cars? In this lesson students will learn how to control mechanical processes using computer software and hardware. The software communicates through a hardware interface with different inputs and outputs.

Understandings 1. Flowcharts provide a step by step schematic representation of an algorithm or process. 2. Control systems are designed to provide consistent process control and reliability. 3. Control system protocols are an established set of commands or functions typically created in a computer programming language. 4. Closed loop systems use digital and analog sensor feedback to make operational and process decisions. 5. Open loop systems use programming constants such as time to make operational and process decisions.

Knowledge and Skills It is expected that students will:    

Create detailed flow charts that utilize a computer software application. Create control system operating programs that utilize computer software. Create system control programs that utilize flowchart logic. Choose appropriate input and output devices based on the need of a technological system.  Differentiate between the characteristics of digital and analog devices.

 Judge between open and closed loop systems in order to choose the most appropriate system for a given technological problem.  Design and create a control system based on given needs and constraints.

Essential Questions 1. What are the advantages and disadvantages of using programmable logic to control machines versus monitoring and adjusting processes manually? 2. What are some everyday seemingly simple devices that contain microprocessors, and what function do the devices serve? 3. What questions must designers ask when solving problems in order to decide between digital or analog systems and between open or closed loop systems?
