• 0 - 20
• 3000 - 4000
• 200 - 650
• 1900 - 2400

Which of the following options best describes the acceptable range of the potentiometer values for Joint 4 used while mastering?

• 1600 - 2000
• 200 - 650
• 0 - 20

Which of the following best describes what the ‘Arm Mastering’ example project in VEXcode V5 displays?

• It displays the speed that the motors are running.
• It displays the Build Instructions.
• It displays the potentiometer values on the V5 Brain and indicates if those values are within the predetermined range (PASS) or not within the acceptable range of values (FAIL).
• It displays interactive buttons on the V5 Brain's screen that allows you to manipulate the Workcell.

Which of the following best describes why potentiometers are required to be installed at a certain position and at a certain rotation on the V5 Workcell?

• To provide power to the V5 Brain.
• To download and run a VEXcode V5 project.
• To make the motors on the Workcell spin faster.
• To ensure the V5 Workcell knows its ‘home location’ that allows it to operate within its range of motion to prevent damage.

Which of the following best defines a potentiometer?

• A machine that converts one form of energy into mechanical energy.
• A button designed to stop dangerous equipment.
• An analog variable resistor, which provide a variable voltage value based on the position of the wiper arm (the piece that moves across the resistive track material) inside of the potentiometer.
• A sensor designed to measure the acceleration and angular velocity of an object along the (x, y, z) axes.

True or False: The ‘Arm Install' example project actually moves the motors connected to the potentiometers at each joint on the Workcell to their target location, while the 'Arm Mastering’ example project is used to verify and display the current mastering values so they can be recorded and used when coding the Workcell. True

• True
• False

Which of the following best describes when to use an E-stop?

• If the machine's functioning becomes a hazard to individuals, other machinery, or itself.
• When you need to charge the V5 Battery.
• To download and run a VEXcode V5 project.
• To measure the angle in degrees that the motors turn.

Which of the following devices is coded to simulate an emergency stop button on the Workcell?

• Potentiometer
• Smart Motor
• Bumper Switch
• Mastering Jig

Which blocks in VEXcode V5 are used to code the Bumper Switch to simulate an emergency stop?

• [Print] and
• {When bumper} and [Activate emergency stop]
• {When started} and [Set joint speed]
• (Timer) and

Which of the following best describes a pinch point?

• A mechanism that will completely stop its assigned equipment or electrical circuit.
• Something that occurs wherever a moving object comes in contact with another object.
• Analog variable resistors, which provide a variable voltage value based on the position of the wiper arm.
• A type of calibration process to increase the positioning accuracy of the robot.
