Unit 8- VEXcode

What creates the magnetic field for the Electromagnet?

• An electric current.
• An electrical outlet.
• A button on the VR Robot.
• An additional magnet.

What objects can the Electromagnet pick up in VEXcode VR?

• Disks
• Buildings
• Balls
• Pen drawings

What is one use of the Electromagnet in VEXcode VR?

• To identify the color of disks.
• To solve the Wall Maze.
• To pick up and put down disks with metal cores.
• To find metal in the walls of Playgrounds.

What is the best description of the [Energize Electromagnet] block?

• Sets the Electromagnet to two different modes: Pick Up or Put Down.
• Energizes the Electromagnet to press both Bumper Sensors.
• Energizes the Electromagnet to attract all metal objects in a Playground.
• Sets the VR Robot Electromagnet to two different modes: Boost or Drop.

What happens when the [Energize Electromagnet] is set to boost while near a disk?

• The Electromagnet attracts the disk.
• The Electromagnet drops the disk.
• The Dashboard reports the disk being picked up.
• Nothing happens.

What happens when the [Energize Electromagnet] is set to drop while the Electromagnet sensor is holding a disk?

• Nothing happens.
• The Dashboard reports the disk being released.
• The Electromagnet picks up the disk.
• The Electromagnet releases the disk.

True or False: The [Energize Electromagnet] block is a reporter block that can be used with Drivetrain blocks to pick up disks.

• True
• False

Describe what the VR Robot will do in this project.

• The VR Robot will drive forward 800 millimeters (mm), turn left 180 degrees, drive forward 800 millimeters (mm) and drop any disks that were picked up.
• The VR Robot will energize the magnet, drive forward 800 millimeters (mm), turn left 180 degrees, drive forward 800 millimeters (mm) and drop any disks that were picked up.
• The VR Robot will energize the magnet, drive forward 800 millimeters (mm), turn left 180 degrees, and drive forward 800 millimeters (mm).
• The VR Robot will energize the magnet, drive forward 200 millimeters (mm), turn left 90 degrees, drive forward 200 millimeters (mm) and drop any disks that were picked up.

In this project, what will happen if the Down Eye Sensor does NOT detect an object?

• The VR Robot will check the condition of the again.
• The VR Robot will drive forward.
• The VR Robot will stop driving.
• The VR Robot will stop driving, then set the Electromagnet to 'boost'.

Which VR Robot sensor determines the color of an object when close enough?

• Gyro Sensor.
• Distance Sensor.
• Eye Sensor.
• Location Sensor.
