- AWelding tools
- BMaterial application tools
- CPainting tools
- DMachining and assembly tools
12What are the advantages of using automatic tool changers?
- AIncreases productivity by allowing the robot to perform multiple operations.
- BSlows down production jobs because the operator must change out the tools.
- CAllows the robot to lift heavier loads.

- ATrue
- BFalse
14Which of the following best describes how breakaway devices and overload sensors provide protection for robotic systems?
- AThey break to prevent strain on more expensive parts of the system.
- BThey are made of strong materials that do not break easily so that excess strain is transferred to more expensive components.
- CThey use sensors to locate parts that need to be moved.
- DThey send a signal to the controller when a misaligned part is detected.
15Which of the following best describes compliance?
- AWhen a robot does what it is told to do.
- BWhen a robot meets all production standards.
- CThe ability of an end-effector to tolerate the misalignment of mating parts.
- DThe ability of a robot to auto tool change.
16How can compliance of an end effector be increased?
- ABy adding a Mobile proximity warning system
- BBy adding a remote center bearing (RCB) system
- CBy increasing the amount of "play" in the gripper system
- DBy adding a remote center compliance (RCC) device
