etc. cutting technologies are connected with each other?
3. How Robotics can contribute to the following fields: Agriculture, Security and Surveillance,
Medical field, Extreme geographical location and outer planet exploration.
4. What are the ultimate goals of Robotics and Industry Automation?
5. What do you mean by 4D. Does robotics help us in these circumstances? How?
6. What are the limitations of human beings? Why do we want to become a superhuman?
7. Write down the detailed functionalities, technical configurations and special features of any
two humanoid robots.
8. What are the basic laws of AI Robots that should be maintained while designing and building
a robot?
9. Which Laws should be maintained to use robots in a society.
10. There are different types of uncrewed vehicles. Discuss details about and 4 types of
uncrewed vehicles.
11. Write a short note about parallel robots and 3D printers.
12. Write details about Hardware architecture.
13. There are mainly three paradigms of robotics based on sase-plan-act. Explain briefly about
those but write a deep discussion about Hybrid paradigm.
14. What is the main difference between End-effector and manipulator? Write short notes about
three different types of end effector.
15. Why Chains, Gears and Link mechanisms are so important in Mechanical engineering?

problems of DC motors for using in robotics? How those can be resolved.
17. What are the differences, advantages, and disadvantages of Electric actuator, Hydraulic
actuator and Pneumatic actuator?
18. Why is perceiving the environment so important in robotics? Differentiate between active
and passive sensors.
19. Briefly described: Mecanum Wheel, Monstrom LEGO, LIDAR, Emotiv Epoc, LEAP and
MYO.
20. Why is it always stated that Processing devices and Control software are related with each
other? Briefly discuss a few types of Control software.
21. Discuss a comparative study on MIcro-controllers, different versions of Arduino, different
families of single board computers, FPGA, PLC and traditional microprocessor based computers.
22. Write down the detailed functionalities, technical configurations and special features of your
most favorite robot (non humanoid).
Forward and Backward Kinematics on Manipulator:
1. Why Kinematics is important on the study of Manipulator
2. Explain the differences between Forward and Backward Kinematics
3. Suppose your Student id is (xxxxxxxx) consider the first two digits as the length of the
first arm, next two digits as the length of 2nd arm, next two digits as the length of end
effector and last two digits as the height of the manipulator. Consider that your end
effector will always work on downward that means perpendicular to the ground.
a. Can your manipulator reach on (15, 5, 10) point? If yes, what would be the angle
of Theta-1, Theta-2 and Theta-3. If not why? Show the calculation in detail.
b. If all Theta-1, Theta-2 and Theta-3 are 45 degrees what would be the end point of
your end effector in 3D space.
Geometrical models of image formation
1. Why do we need projective geometry?
2. Suppose the H.C of point X is [2p 3q 4r]. What would be the heterogeneous coordinate of
this point? Here p, q, r are the 4th, 5th, 6th digit of your BRACU ID.
3. Mention equivalent H.C point of [5 10 3]
4. In our pinhole camera model, for convenience, we have moved the image plane in front
of the camera. What would be the mapping from world coordinate [X Y Z] if the image
plane is situated at f distance from the camera origin or camera centre?
5. Suppose the calibration matrix K is given below. If the world coordinates of a 3D point is
[3 9 1] then what would be the point in the 2D image plane? Here x and y are the 5th and
6th digit of your BRACU ID
a.
6. How can you generate a virtual image with a concave lens?
