10. What is meant by robot anatomy?
Ans. Study of structure of robot is called robot anatomy. Manipulator is constructed of a series of joints and
links. A joint provides relative motion between the input link and the output link.

B. Long answer type questions.
1. What are the three degrees of freedom associated with the arm and body motion?
Ans. l Right (or) left movement (X-axis motion)
l In and out movement (Y-axis motion)
l Vertical movement (Z-axis motion)
2. Define an Industrial Robot.
Ans. An industrial robot is an automatically controlled, reprogrammable, multipurpose manipulator
programmable in three or more axes. A programmable mechanical device that is used in place of a
person to perform dangerous or repetitive tasks with a high degree of accuracy.
3. Define payload capacity of Robot?
Ans. The maximum load which can be carried by the manipulator at low or normal speed.
4. Define base and tool Coordinate system.
Ans. A tool coordinates definition system capable of easily obtaining a transformation matrix for defining a tool
coordinates system of a robot. The tool coordinates system at the 0° position of the robot is rotated around
each axis so that the tool coordinates system becomes parallel to a base coordinates system.
5. Name the important specifications of an industrial robot.
Ans. l Accuracy l Repeatability l Degree of Freedom
l Resolution l Envelope

6. What are the four basic robot configurations available commercially?
Ans. l Cartesian coordinate system
l Cylindrical coordinate system
l Polar or spherical coordinate system
l Revolute coordinate system
7. What is meant by pitch, yaw and roll?
Ans. Pitch is rotation around the X axis, yaw is around the Y axis, and roll is around the Z axis. Yaw is side to side
swinging around an axis. Pitch is up and down movement about an axis and roll is rotatory motion about
an axis.
8. List out the robot major components?
Ans. 1. Robot arm 2. End of arm 3. Power source
4. Controller 5. Sensor 6. Actuator
9. What is an end effector? Give examples?
Ans. It is a device that is attached to the end of the wrist arm to perform specific task. e.g. Tools, Welding
equipment, End of arm tooling.
10. What is meant by workspace and work volume?
Ans. The space in which the end point of the robot arm is capable of operating (or) the reach Ability of robot
arm is known as workspace. The volume of the space swept by the robot arm is called work volume.
