(Electronics & Control Engineering)
Time: three hours Max Marks: 80
ans any 5 ques.
All ques. carry equal marks
1. (a) De¯ne a robot. With help of sketch define pitch, yaw and roll motions of a robot wrist.
(b) explain the origin and different generations of robots. Sketch and discuss the work envelope of a
cylindrical robot.
2. (a) What is the work envelope of a robot, sketch and discuss 2 views to indicate the work envelope
of a
i. cartesian robot.
ii. polar robot.
(b) State the laws of robotics and explain the different mechanical design considerations of robots.
3. (a) elaborate the advantages of hydraulic actuator systems over electrical motors? Sketch and discuss
a pneumatic power drive used for robots.
(b) elaborate the functions of sensors? How do you sense the positional accuracy of a robot? define
the suitable kind of sensor used to measure the position.
4. (a) How is a robot end-e®ector speci¯ed? explain the design considerations in the robot end-of-the-arm
tooling.
(b) What is the function of a manipulator? explain the working of a robotic manipulator arm with a
sketch.
5. discuss different force control methods in robot manipulators.
6. elaborate the di®erent kinds of grippers used in industrial robots? define any 4 of them.
7. How does direct kinematics di®er from inverse kinematics? explain Euler angle representation for orien-
tation.
8. Write short notes on any 3 of the following:
(a) Asimov's laws of robotics.
(b) Hydraulic drives.
(c) Magnetic grippers.
(d) Robot applications in manufacturing.
