Electromagnet Quiz

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 on the VR Playground can the Electromagnet on the VR Robot pick up?

• Disks

• Buildings

• Balls

• Pen drawings

What is one use of the Electromagnet on the VR Robot?

• 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 command?

• Sets the Electromagnet to two different modes: Left or Right.

• Energizes the Electromagnet to press both Bumper Sensors.

• Energizes the Electromagnet to attract all metal objects in a Playground.

• Sets the Electromagnet to two different modes: 'BOOST' or 'DROP'

What happens when the energize command 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 command is set to 'DROP' while the Electromagnet 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 command returns a Boolean value that can be used with Drivetrain commands to pick up disks.

• True

• False

Which of the following best describes the use of comments in a project?

• To turn on the Electromagnet in a project.

• To plan and organize the behaviors needed to complete the goal of the project.

• To make a project more disorganized and less efficient.

• To report the value of a sensor on the VR Robot.

Which of the following best describes 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 200 millimeters (mm), turn left 90 degrees, drive forward 200 millimeters (mm) and drop any disks that were picked up.

• The VR Robot will energize the magnet, drive forward 800 millimeters (mm), and turn left 180 degrees.

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 front_eye.detects command 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.'
