2. Describe the working principle along with diagram for 1) Infrared Sensor, 2) Laser 9
Distance Sensor and 3)Touch sensor, to be used in mechtronics systems.

3. Define Mechatronics system in terms of block diagram, graphical and lingustic 5


forms. Give suitable examples of four mechatronics systems.

4. a Classify various actuators in a tree diagram manner used for mechatronics systems. 5

4. b Give the construction, working principle, features, applications and diagrams of 8


bent axis motor and vane motor.

5 Design a 7 kg Mechatronics washing machine using Mamdani Fuzzy AI Technique. 18

The inputs are a)Weight of the clothes (0-7 kg); b) Level of dirtiness (0-100%) and

c)Level of oily and greasiness in the clothes (0-100%).Explain all the steps during

design of the Mechatronics system using above method. Find out the outputs {i.e.

washing time(0-50 minutes) and quantity of detergent(0-250gms)} for the inputs

5.2 kg (clothes), 65% (dirtiness level) and 75% (level of oily and greasiness in the

clothes).
