Fluid valves and relays Integrates microelectronics into electrically controlled devices. Hard disk, CD drives, automatic washing machines Intelligent control in mechatronic system E. Design Process 1. The need 2. Analysis of the problem 3. Preparation of a specification 4. Generation of possible solutions 5. Selections of a suitable solution 6. Production of a detailed design 7. Production of working drawings Design process for any system involves a number of stages.

Design Process In designing mechatronic systems; one of the steps is the creation of a model of the system, that predictions can be made regarding its behaviour with reference to the inputs.

System: A box or block diagram which has an input and an output. Mechatronic Design Process Advantages and Disadvantages of Mechatronics Advantages Disadvantages Cost effective and reliable product High initial cost of the system. High degree of flexibility and productivity Imperative to have knowledge of different engineering fields for design and implementation. Greater extent of machine utilisation. Specific problems for various systems will have to be addressed separately and properly. Reduction in the capital expense due to integration of complex systems.

Sensors Automotive Sensors Sensors This deflection may be further converted into an electrical output by strain gauges called secondary transducer. Sensors Examples Classification of Sensors The sensors are classified into the following criteria: 1. Primary Input quantity Measurand 2. Transduction principles Using physical and chemical effects 3. Material and Technology 4. Property 5. Application All these sensors are used for measuring one of the physical properties like Temperature, Resistance, Capacitance, Conduction, Heat Transfer etc.

Classification of Sensors Based on the conversion phenomenon i. Photodiodes Applications Smoke detectors, compact disc players, and televisions, remote controls in VCRs, clock radios, street light Photodiodes This leads to the production of a collector current which is a measure of the light intensity.

In electronics, a multi-transistor configuration called Darlington pair Photoresistor: A photoresistor or light-dependent resistor, LDR, or photo-conductive cell is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity photoconductivity. Principle of working of Light sensors Passive Principle of working of Proximity switches A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact.

The microswitch is a small electrical switch which requires physical contact and a small operating force to close the contacts. For example: A conveyor belt. Principle of working of Proximity switches a Lever-operated b roller-operated c cam-operated switches. Applications: Checking the closure of doors, used with tachometers etc. Hall effect sensors A Hall effect sensor is a device that is used to measure the magnitude of a magnetic field.

Hall in and is called the Hall effect. Excitation Electrical Output Transducer Mechanical detector-transducer elements are; 1. Thermal detectors 4. A thermocouple that changes temperature differences into a small voltage. They develop their own voltage or current.

Externally-powered transducer. May absorb some energy. Convert input into analogue. Terms associated with Transducers Transducer Sensitivity: The relation between the measurand and the transducer output signal. Difference between Sensor and Transducers Transducer — these are elements when subjected to physical change experience a related change. Sensors — the term sensor is used for an element which generates a signal which is proportional to the quantity being measured.

Difference between Sensor and Transducers Difference between Sensor and Transducers Basis For Comparison Sensor Transducer Definition Senses the physical changes occurs in the surrounding and converting it into a readable quantity. The transducer is a device which, when actuates transforms the energy from one form to another. Components Sensor itself Sensor and signal conditioning Function Detects the changes and induces the corresponding electrical signals.

Conversion of one form of energy into another. Thermistor, Potentiometer, Thermocouple, etc. End of Module. You just clipped your first slide! Clipping is a handy way to collect important slides you want to go back to later.

Intelligent Knowledge-Based Systems pp Cite as. Mechatronics is an emerging engineering area that will likely alter the fundamental nature of engineering, particularly and initially in the disciplines of electrical and mechanical engineering. The mechatronics approach provides multi-disciplinary knowledge and skills necessary to apply mechatronics in product design, development and manufacturing; and serve as a model for multi-disciplinary programs cut across traditional engineering disciplines.
