In this project, what will happen if the Down Eye Sensor detects an object?

The VR Robot will check the condition of the
The VR Robot will use the Eye Sensor to check the color of the object.
Which block can be used to determine if the Eye Sensor (Down Eye and Front Eye) is close enough to an object to detect a color?
<Distance near object> block.
(Color brightness) block.
<Near Object> block.
<Color Sensing> block.
Which of the following describes one reason to use a [Turn to heading] block versus a [Turn] or [Turn for] block?
[Turn to heading] makes projects repeatable from one run to another because the VR Robot will move to the specified heading regardless of the previous position of the VR Robot.
[Turn to heading] will orient the VR Robot to the left every time.
[Turn to heading] will fix any turning errors in your project.
[Turn to heading] is based on the readings from the Distance Sensor, so it is more accurate than other turn commands.
What is an electromagnet?
A magnet that is attracted to plastic.
A magnet where the magnetic field is produced by an electric current.
A magnet that needs to be plugged into a wall outlet to work.
A magnet used to find hidden electrical sockets.

De-energizes the Electromagnet to pick up disks with metal cores.
Energizes the Electromagnet to drop disks with metal cores.
Instructs the Electromagnet to drop disks with metal cores.
What happens when the [Energize Electromagnet] is set to drop while the Electromagnetic sensor is holding a disk?
Nothing happens.
The Dashboard reports the disk being released.
The Electromagnet releases the disk.
The Electromagnet picks up the disk.
Describe what the VR Robot will do in this project.
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 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.
True or False: Loops can be nested by dragging the loop you want to nest inside of another existing loop in the workspace.

What is one reason to use nested loops?
Creating a larger, more complex project.
Creating a smaller, more condensed project.
Repeating an action fewer times than needed.
To use as many blocks as possible in one project.
Which two sensors are being pointed to on the VR Robot?
The Left and Right Bumper Sensors.
The Front Eye and Down Eye Sensors.

To have the Electromagnet Sensor pick up and place disks.
To be able to have the Down Eye Sensor check for the color red.
To have the Distance Sensor report how far the VR Robot is from an object.

The condition of the Front Eye Sensor detecting green will be checked.
The condition of the Down Eye Sensor detecting red will be checked.
The condition of the Front Eye Sensor detecting none will be checked.
The condition of the Front Eye Sensor detecting red will be checked.
Why is the [If then] block nested inside the [Forever] block for this project?
Conditions of the [If then] block will be checked continually if nested in a [Forever] block. The VR Robot will use the Down Eye Sensor to continually check for an object.
The [Forever] block is not needed.
If the [Forever] block was not used, the [If then] block would only be executed and checked four times.
To turn right for 90 degrees when an object is detected.
