  1. ME 6405/ME 4447 Introduction to Mechatronics Instructor: Professor Charles Ume Lecture #5

  2. 1. Reading assignment for this week and next week Read Chapters 1-4 in Basic Microprocessors and the 6800, by Ron Bishop. Chapter 1 Basic Electronic Principles Chapter 2 Logic Elements Chapter 3 Number Systems Chapter 4 Digital Arithmetic There will be questions and answers the rest of this week and next week based on your reading assignment. Revision

  3. 2. Why do we teach microprocessor applications (or Mechatronics) in ME? It used to be taught only in EE. - Few ME schools/departments were teaching it in early 80's: GIT, Stanford, Berkeley, Penn State, University of SC, Rensselaer Polytechnic Institute, British Columbia and etc. - Reasons: Emphasis in manufacturing and automation - Today's consumer products (examples: cameras, automobiles, camcorders, sewing machines, TVs, cell phones) incorporate electronics and micro-controllers Revision Cont’d

  4. Micro-controller is at core of our mechatronics courses as discussed earlier. Therefore, it makes sense to discuss its various applications in mechatronics systems or mechatronics devices. APPLICATION OF MICROCONTROLLERSin Mechatronics Systems/Devices

  5. The main application in the auto industry is in the Engine Control Module (ECM) for: controlling the: spark, fuel, and air going to the engine to minimize emissions and maximize fuel economy and performance Automobile Industry

  6. Other applications include: the new Body Computer Module (BCM) entertainment system theft deterrent systems climate control dashboard display lighting traction control navigation systems other control functions like transmission, diesel, suspension and power steering controllers. Automobile Applications Cont’d

  7. Windshield wiper: M68HC11-based micro-controller was developed to test and implement smart wiper concept for a car. Standard intermittent windshield wiper is concept of smart wiper that automatically turns itself on or off and adjusts its wiping cycle according to intensity of rain. Automobile Applications Cont’d

  8. Temperature controls Timing functions (various types), e.g., hoppers for measuring flours, sugar, etc. Product counting Speed control of conveyor belts/chains Robot control Process monitoring and control Humidity Controls Factories

  9. Smart houses: Burglar alarms page you/call police Garage door opener Temperature control Program your thermostat or stove to turn on an hour before you return Program light/TV control to turn on at different times during your absence Turn a stove/oven on to start cooking/baking before you leave your office Homes

  10. Data acquisition systems Automating experiments LABS

  11. Camera, camcorder, VCR, washing machine, dryer, TV, microwave oven, oven, video games, cell phones, children’s toys etc. Consumer Products

  12. US Olympic Committee Rowing Data Acquisition System (RDAS) at core of RDAS onboard electronic unit is 68HC11 microcontroller current RDAS monitors oar angle, oar torque (force about the oar lock), boat speed, and boat acceleration on four athletes and transmits data to receiving unit integrated with IBM laptop on coach's launch (a small motorboat or a large boat that operates from a ship). Sports

  13. Flaps in airplane wings, and airplane control surfaces NC machines Other Applications
