  1. Introduction to Mechatronics Jr-Lung (Eddie) Lin Department of Mechanical and Automation Engineering, I-Shuo University

  2. Introduction Mechatronicsis synergistic integration of mechanical engineering, electronics and intelligent computer control in design and manufacture of products and processes

  3. What CAD/CAM/CAD • CAD: Computer-Aided Design • CAM: Computer-Aided Manufacturing • CAE: Computer-Aided Engineering

  4. CAD/CAM/CAE software • CAD – 2D drafting • AutoCAD, TwinCAD, etc. • CAD – Solid modeling • Solid Edge, SolidWorks, Mechanical Desktop(MDT), etc. • CAM • SOLIDCAM, SURFCAM, MasterCAM, SmartCAM, etc. • CAE • ANSYS, ABAQUS, NASTRAN, ADAMS, MOLDFLOW, etc.

  5. Microprocessor • CPU for Computers • No RAM, ROM, I/O on CPU chip itself • Example:Intel’s x86, Motorola’s 680x0 Many chips on mother’s board Data Bus CPU General-Purpose Micro-processor Serial COM Port I/O Port RAM ROM Timer Address Bus General-Purpose Microprocessor System Mahdi Hassanpour

  6. Microcontroller • A smaller computer • On-chip RAM, ROM, I/O ports... • Example:Motorola’s 6811, Intel’s 8051, Zilog’s Z8 and PIC 16X CPU RAM ROM A single chip Serial COM Port I/O Port Timer Microcontroller Mahdi Hassanpour

  7. Microprocessor vs. Microcontroller Microprocessor • CPU is stand-alone, RAM, ROM, I/O, timer are separate • designer can decide on the amount of ROM, RAM and I/O ports. • expansive • versatility • general-purpose • Microcontroller • CPU, RAM, ROM, I/O and timer are all on a single chip • fix amount of on-chip ROM, RAM, I/O ports • for applications in which cost, power and space are critical • single-purpose Mahdi Hassanpour

  8. GPIB PC Board Serial/paralell CAN BUS PC-based Measurement and Control

  9. Sensors and Actuators • Sensor A device that converts an environmental condition into an electrical signal. • Actuator A device that converts a control signal (usually electrical) into mechanical action (motion). (Taken together, sensors, actuators, controllers, and power supply form the basic elements of a control system.)

  10. Actuators-Motors

  11. The Following Special Formulation is Offered Mechatronics studies synergistic fusion of precise • mechatronical units, • electronic, • electro technical and computer components for the purpose of designing and manufacturing qualitatively new • modules, • systems, • machines and complexes of machines with intellectual control of their functional movements

  12. Comments to the Definition • Mechatronics studies special conceptual approach to construction of machines. • The definition emphasizes synergetic character of components’ integration in mechatronic objects. • Integrated mechatronic components are always chosen at the designing stage. • Methods of parallel designing serve as methodological basis for Mechatronic Systems (MS) development. • The main objects that mechatronics studies are mechatronic modules. • MSare intended to perform a set movement. • In MS methods of advanced intelligent control are used to secure high quality in performing precise movements.

  13. Principles of Construction MS Generalized Scheme of Machine with Computer Control of Movement The structure of a traditional machine e.g.: cutting forces for machining processes, contact forces and moments of forces at assembly, reactive force of the liquid jet at hydraulic cutting determ non-determ

  15. Computer Control Device Basic Functions • Control of mechanical movement process on-line with current sensor data analysis. • Arrangements to control MS functional movements. • Interaction with operator via human-machine interface off-line and on-line interaction at the moment of MS movement. • Data exchange between peripheral devices, sensors and other devices of the system.

  16. The Core of Mechatronic Approach At the stage of designing one interface, as a separate device, is excluded out of a traditional structure, but physical essence of transformation carried out by this module is kept. It consists in integrating of components probably of different physical nature into a uniform functional module. in other words

  17. Basic Advantages in Comparison with Traditional Means of Automation • rather low cost; • ability to perform complicated and precise movements (of high quality); • high reliability, durability and noise immunity; • constructive compactness of modules; • improved overall dimension and dynamic characteristics of machines; • opportunity to rebuild functional modules to sophisticated systems and complexes.

  18. Modern Trends of MS Development • Office equipment; • Computer facilities; • Photo and video equipment; • Machine-tool construction and equipment for automation of technological processes; • Robotics;

  19. Modern Trends of MS Development • Aviation, space and military techniques; • Motor car constructor;

  20. Modern Trends of MS Development • Micro machines; • Control and measuring devices and machines; • Simulators for training of pilots and operators; • Show-industry; • Non-conventional vehicles.

  21. Requirements of the World Market in the Considered Area • Standard ISO 9000; • Necessity for active introduction of forms and methods of international engineering and putting new technologies into practice; • Increasing role of small and average industrial enterprises in economy owing to their ability to quick and flexible reaction to changing requirements of the market; • Intellectualization of mechanical movement control systems and technological functions of modern machines.

  22. Fundamental Problems • Structural integration of mechanical, electronic and information departments into a uniform creative staff; • Education and training of engineers specialized in mechatronics and managers able to organize integration and supervise work of strictly specialized experts with different qualifications; • Integration of information technologies from various scientific and technical fields into a uniform toolkit to provide computer support of mechatronic problems; • Standardization and unification of all used elements and processes at designing and manufacturing MS.

  23. Levels of Mechatronic Systems’Integration The First Level • conveyors, • rotary tables, • auxiliary manipulators

  24. Levels of Mechatronic Systems’Integration The Second Level • operated power machines (turbines and generators), • machine tools and industrial robots with numerical program management

  25. Levels of Mechatronic Systems’Integration The ThirdLevel Synthesis of new precise, information and measuring high technologies gives a basis for designing and producing intellectual mechatronic modules and systems.

  26. Career Paths in Mechatronics • mechatronics is seen as a prime career path for mechanical engineers of the future; • mechanical engineers with a mechatronics background will have a better chance of becoming managers; • classically trained mechanical engineers will run the risk of being left out of the interesting work.
