Write your answers on a separate sheet of paper. Do not write in this book.
1. Identify the fi ve major components of a robot and explain the purpose
of each.
2. What is the technical name for the robot’s hand?
3. Name the three types of power supplies used to power robots. List the
advantages and disadvantages of each.
4. In terms of degrees of freedom, explain why the human hand is able
to accomplish movements that are more fl uid and complex than a
robot’s gripper.
5. List and explain the six degrees of freedom used for robots.
6. Servo robots can be classifi ed as intelligent or highly intelligent.
Explain the difference between these two classifi cations.

means?
8. Servo robots are considered closed-loop. Sketch a diagram of a
closed-loop system and explain how it works.
9. What determines the shape of the robot’s work envelope?
10. Why should you be concerned about the work envelope shape when
installing a robot for a particular application?

1. Visit Fanuc Robotics at www.fanucrobotics.com and select videos
from the side menu. This Web site provides a number of different
robots performing various tasks. As you watch these video fi les, try to
identify the robot confi guration that is performing the task.
2. Visit the following robot manufacturers’ Web sites. Locate the
products they manufacturer and identify the robots by the
confi gurations discussed in this chapter.
• www.adept.com (Adept Technology, Inc.)
• www.motoman.com (Motoman, Inc.)
• www.apolloseiko.com (Apollo Seiko)
• www.kawasakirobotics.com (Kawasaki Robotics (USA), Inc.)
• www.abb.com/robots (ABB)
3. From the above Web searches, did you fi nd any robot confi guration
that is manufactured more than the others. If so, identify this robot
confi guration and explain why you believe this to be the case.
