    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.

                                                                                                        21 st
                  C.  Competency-based questions:     HOTS                                             Century   #Digital Literacy

                      1.   Imagine your school decides to use a robot for library management. What type of robot would you design, and
                         what features (sensors, actuators, computing system) would it need?
