MECHATRONICS - Introduction

 MECHATRONICS

MECHATRONICS:-

                Mechatronics is the synergistic integration of electronics engineering, electrical engineering, control engineering & computer technology maintenance of a wide range of engineering products and processes with mechanical engineering for the design, manufacture analyses and processes.

Mechatronic systems-

A Mechatronics system is a system that comprises a combination of mechanical, electrical, telecommunications, control and computer science technologies.

Elements of Mechatronic system:-

1.  Actuators & Sensors
2.  Signals & Conditioninglogic
3.  Digital Logic Systems
4.  Software & Data Acquisition Systems
5. Compters & Display

    1. Sensors & Actuators

• Sensors and Actuators come under Mechanical Systems.
• Sensors detect the state of parameters, inputs and outputs.
• Various Sensors used in mechatronic systems
1. Linear and Rotational sensors
2. Acceleration, Torque, Force Sensors
3. Flow sensors
4. Temperature sensors
5. Proximity sensors
6. Light sensors

• Actuators produce motion or cause some action.
• Various Actuators used in mechatronic systems
1. Hydraulic & Pneumatic Actuators
2. electro-mechanical actuators
3. Piezoelectric Actuators
4. Electric Motors - AC, DC, Servo, Servo motors

                

    2. Signals & Conditioning:-

• Mechatronic System deals with two types of signals and conditioning
  - Input
  - Output
• Input device receives signal from mechatronic system via interfacing devices and sensors and sent to the control circuits for processing the data.
• Various types of Input signal conditioning used in the mechatronic system
1. Discrete circuits
2. Amplifiers
3. Analog-to-Digital
4. converters
5. Digital to Digital              
• The output signals from the system are sent to output/display devices through interfacing devices.
• Various types of output signal conditioning used in the mechatronic system
1. Digital & Analog
2. Display Decoders
3. Amplifiers
4. Power transistors
5. power op amps  

     3. Digital logic systems   

• Digital logic devices control overall system operation    
•  The various digital logic systems used in the mechatronic system are
1.  Logic Circuits
2.  Micro Controllers
3.  Programmable Logic Controllers
4.  Sequencing & timing controls
5.  Control Algorithms

    4. Software and data acquisition systems  

• The data acquisition system acquires the output signals from sensors in the form of voltage, frequency, resistance etc.   

    5. Computers and display devices  

• Computers are used to store a large number of data and process further through software. Display devices are used to give visual feedback to the user.
