Chapter 1: Introduction to Mechatronics

• Objectives: Explain mechatronics, its relevance in engineering design, systems, measurement systems and elements of open-loop and closed-loop control systems
• What is mechatronics?: A combination of 'mecha' (mechanism) and 'tronics' (electronics)
• Mechatronics System: A concurrent integration of mechanical engineering with electronics, and intelligent computer control.
• Mechatronics Design Process:
  • The need
  • Analysis of the problem
  • Preparing a specification
  • Generating possible solutions
  • Selection of solution
  • Production of a detailed design
  • Production of working drawings

Chapter 1.3: Systems

• Modelling systems: Predicting a system's behavior when inputs occur.
• Connected Systems: Systems with multiple interconnected blocks.
• Measurement systems: Sensor (responding to the quantity measured), signal conditioner, and display.

Chapter 1.5 : Control Systems

• Feedback: Signals fed back to modify output, ensuring it meets the required value.
• Open loop: No feedback; output not affected by the output.
• Closed loop: Feedback; output affects the input to maintain a consistent output.

Chapter 2: Sensors and Transducers

• Objectives: Description of sensor performance, classification, and evaluation in various measurements (motion, position, force, flow, and temperature).
• Sensor Types: Analog (continuous) and Digital(discrete) sensors. Active (needs external power) and Passive. Deflection and Null types.
• Quality Parameters:
  • Sensitivity
  • Resolution
  • Accuracy
  • Precision
  • Backlash
  • Repeatability
  • Linearity
• Instrumentation System: Sensors, signal conditioner, display, and feedback sensor.

Chapter 3: Signal Conditioning and Realtime Interface

• Objectives: Explain signal conditioning, elements of data acquisition and control systems, and practical aspects of computer interfacing.
• Data Acquisition and Control System:
  • Elements involved in real time interfacing of the computer with a device
• Real time interfacing: connecting a computer to a real-world process.
• Data acquisition: converting real-world data (motion, temperature) into electrical signals that computers can read.
  • Types of I/O process
  • Direct memory access (DMA)
  • Interrupt request (IRQ)
  • Programmed I/O (PIO)
  • Memory mapping

Chapter 4: Electrical Actuation Systems:

• Objectives: Evaluating the operational characteristics of electrical actuation systems (relays, solenoids, d.c. motors, a.c. motors, steppers), explain DC motor principles (permanent magnet, brushless), and variable reluctance, permanent magnet, and hybrid stepper motor forms.
• Electrical Systems:
  • Switching devices (mechanical and solid-state) to turn on/off devices or circuits.
  • Electromagnetic based devices such as Solenoids in hydraulic/pneumatic systems.
  • Actuators like motors for rotational motion.
