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.

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.

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 <Eye Sensor near object> 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 of the following best describes the project flow in this VEXcode VR project?

• The VR Robot will begin by moving forward 300 millimeters (mm) and will turn right 90 degrees. The VR Robot will then turn to a heading of 0 degrees. The VR Robot will repeat all these steps two additional times for a total of three repeats.

• The VR Robot will begin by moving forward 300 millimeters (mm) and will turn right 90 degrees. These two commands will be executed two times in a row because of the [Repeat] loop. The VR Robot will then turn to a heading of 0 degrees. The VR Robot will repeat all these steps two additional times for a total of three repeats.

• The VR Robot will begin by moving forward 300 millimeters (mm) and will turn right 90 degrees. The VR Robot will then turn to a heading of 0 degrees. The VR Robot will repeat all these steps one additional time for a total of two repeats.

• The VR Robot will begin by moving forward 300 millimeters (mm) and will turn right 90 degrees. These two commands will be executed two times in a row because of the [Repeat] loop. The VR Robot will then turn to a heading of 0 degrees.

This project should solve the Disk Mover challenge, but it does not work correctly. What is the error?

• The inner loop is set to repeat three times rather than two.

• The Electromagnet is never instructed to pick up a disk.

• The outer loop is set to repeat two times rather than three.

• The Electromagnet is never instructed to drop a disk.
