1. Which among the following is a false statement regarding “Mechatronic system”?
a) Its initial cost of setup is high
b) Does not require highly skilled labours for operating it
c) More output in less time
d) It provides flexibility in production

Explanation: False statement regarding “Mechatronic system” is that it does not require highly skilled labours for operating it. It does require highly skilled and trained labours for operating the manufacturing machines.

2. Which among the following is a correct statement regarding “Mechatronic system”?
a) Its initial cost of setup is low
b) Cheaper maintenance
c) More output in less time
d) Any individual can operate these systems

Explanation: Correct statement regarding “Mechatronic system” is that it is gives more output in less time compared to the primitive techniques. Machines do not require rest and are built in such a way that it can provide the same accuracy on any other day like it gave on the first day.

3. How many principle axes do a Cartesian robot has?
a) 2
b) 3
c) 4
d) 5

Explanation: A Cartesian robot has 3 principle axes. These are industrial robots that can translate in all X, Y and Z axis. They have three arms that are placed at right angle to each other. A 3D printer is best example of Cartesian robot.

4. What does SCARA stand for in terms of industrial mechatronic robots?
a) Selectively Compliance Assembled Robot Arm
b) Selective Complicated Assembly Robot Arm
c) Selective Compliance Assembly Robot Arm
d) Static Complicated Assembly Robot Arm

Explanation: SCARA stand for Selective Compliance Assembly Robot Arm in terms of industrial mechatronic robots. They are industrial robots that are mainly used in industries for assembling parts and accessories.

6. Primitive methods should be preferred over mechatronic systems for short term manufacturing.
a) True
b) False

Explanation: Primitive methods should be preferred over mechatronic systems for short term manufacturing. This is so because primitive methods are cheaper and easy to apply, whereas mechatronic systems are costlier and can be difficult to install and maintain in short run.

7. Which mechatronic system is also called as Gantry robot?
a) Cartesian Robot
b) Dual Arm Robots
c) SCARA(Selective Compliance Assembly Robot Arm)robot
d) 6 axis robots

Explanation: Cartesian Robots are also called as Gantry robots. These robots can perform lineal motion on the entire 3 perpendicular axes. These Robots are usually used for carrying loads, welding, 3D printing etc.

8. How many degrees of freedom do an industrial redundant arm has?
a) 3
b) 5
c) 7
d) 9

Explanation: An industrial redundant arm has 7 degree of freedom. These industrial arms resemble the human arms and are capable performing every action that a human arm can do. These arms are mainly used in industries for assembling parts and accessories.

9. How many degrees of freedom do an industrial delta robot has?
a) 3
b) 5
c) 7
d) 9

Explanation: An industrial delta arm has 3 degree of freedom. These robots have a dome shaped structure which constitutes of 3 arms joined with universal joints. These arms are mainly used in industries for quick pickup and placing of objects.

10. Who invented delta robot?
a) Grueblerowen
b) Joseph Henry
c) Norman Bel Geddes
d) ReymondClavel

Explanation: Delta robot was invented by ReymondClavel in the early 1980’s. These robots have a dome shaped structure which constitutes of 3 arms joined with universal joints. These arms are mainly used in industries for quick pickup and placing of objects.

11. Who invented first SCARA(Selective Compliance Assembly Robot Arm) robot?
a) Grueblerowen
b) Joseph Henry
c) Hiroshi Makino
d) Walther Bothe

Explanation: Professor Hiroshi Makino invented first SCARA(Selective Compliance Assembly Robot Arm) robot . This revolutionary prototype was created in the year 1978 at Yamanashi University in Japan.

12. How many degrees of freedom do an industrial SCARA (Selective Compliance Assembly Robot Arm) has?
a) 3
b) 5
c) 4
d) 9

Explanation: An industrial SCARA (Selective Compliance Assembly Robot Arm) has 4 degree of freedom. It can translate easily on X axis and Y axis. It has a rotating end that can perform rotational motion on vertical axis.

13. Sensors and transducers are subsystem of mechatronics.
a) True
b) False

Explanation: Sensors and transducers are subsystem of mechatronics. Sensors are transducers are used to collect information from the environment and feed it into computers or microcontrollers that analyses the data and operates accordingly.

14. Which among the following is a correct statement regarding “Mechatronic system”?
a) Its initial cost of setup is low
b) Cheaper maintenance
c) It is suitable for short term business
d) It provides flexibility in redesigning and manufacturing the products

Explanation: Correct statement regarding “Mechatronic system” is that it provides flexibility in redesigning and manufacturing the products. Mechatronic systems can be easily modified to increase or decrease the quality as well as the quantity of products produced.

15. Which among the following is a false statement regarding “Mechatronic system”?
a) Its initial cost of setup is high
b) Requires highly skilled labours for operating it
c) More output in less time
d) Easy to identify faults and repair it

Explanation: False statement regarding “Mechatronic system” is that it is “Easy to identify faults and repair it”. It is rather difficult to identify the fault and repair manufacturing systems. It requires skilled engineers to repair them.
