MECHATRONICS PRESETATION BY ANGSHUMAN DEBRAJ & HRISHIKESH MEHTA GUIDANCE MRS. A. KANSE LECTURER, B.V.J.N.I.O.T., PUNE -43. INDEX WHAT IS MECHATRONICS? MECHATRONICS SYSTEM ELEMENTS REAL-TIME SOFTWARE WHY & HOW OF MECHATRONICS WHY SHOULD WE ADOPT MECHATONICS? BLOCK DIAGRAM OF GENERAL MECHATRONIC DESIGN SYSTEM ELEMENTS MECHATRONICS SYSTEM COMPONENTS MECHATRONIC DESIGN PROCESS CHARACTERISTICS OF MECHATRONIC SYSTEM BENEFIT TO INDUSTRY SCOPE OF MECHATRONICS LIMITATIONS EXAMPLES How the term Mechatronics is derived? The portmanteau "mechatronics" was first coined by Mr. Tetsuro Mori, a senior engineer of the Japanese company Yaskawa, in 1969. Mechatronics may alternatively be referred to as "electromechanical systems" or less often as "control and automation engineering". Mechanisms and electronics Mechatronics system components Mechanical system Actuators •Motors •Pneumatic •hydraulic Graphical Display •LED , LCD •Recorders, CRT Transducers •strain gage •Encoder, RTD •Potentiometer,T/C Output signal Conditioning & interfacing •DAC,Amp,PWM Input signal conditioning & interfacing •Amplifiers •ADC, DAC Digital control Architectures •Logic ckt, PLC •Microcontroller •Communication Why we should adopt mechatronics? In traditional electromechanical systems approach was to inject more reliability. Then control part gets added to enhance the reliability. Less use of computer systems i.e. Sequential design approach (not integrated approach). Because electrical and electronic systems are developing very rapidly and they have fantastic features, interfacing and applications. E.g. electrical machines, semiconductor devices, power devices, microprocessors, microcontrollers, embedded systems, digital control systems, data communication networks, process controllers, etc. Advent combination of computer hardware and software. These electrical and electronic systems can be integrated with mechanical systems and processes.

Safe. Affordable to customers (low cost). Portable . Produced quickly. It should also have the characteristics like serviceability, maintainability, and upgradbility. Scope of Mechatronics Limitations of an individual system can also be altered or compensated due to system integration. Better design of products Better process planning Reliable and quality oriented manufacturing Intelligent process control Intelligent product developments. LIMITATIONS OF MECHATRONICS • Control Design and Implementation is still the domain of the specialist. • Controls and Electronics are still viewed as afterthought add-ons. • Very few practicing engineers perform any kind of physical and mathematical modeling. • Mathematics is a subject that is not viewed as enhancing one’s engineering skills but as an obstacle to avoid. • Very few engineers have the balance between analysis and hardware essential for success in Mechatronics. EXAMPLES OF MECHATRONIC SYSTEMS Automatic washing machine, dishwashers CD players, VCR’s, Camcorders, Document scanners Integrated Circuits (IC) manufacturing systems. Robotics used in welding, nuclear inspection, and robot manipulators. Fax and photocopier machine. Laser printers, in computer peripherals like hard disk drive head positioning systems. Flexible manufacturing systems (FMS). Air conditioners, elevator controls. Automotive mechatronics. (In automobiles like outdoors locking, collision avoidance, ignition systems, antiroll systems, etc.) Microelectromechanical Systems (MEMS) HARD-DRIVE READ-WRITE HEAD CONCLUSION REFERENCES 1.
