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

The VR Robot will stop driving, then set the Electromagnet to 'boost'.

The VR Robot will drive forward, then set the Electromagnet to 'boost'.

The VR Robot will check the condition of the again.

The VR Robot will use the Eye Sensor to check the color of the object.

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.

Which of the following best describes the 'boost' mode of the [Energize Electromagnet]?

Instructs the Electromagnet to pick up disks with metal cores.

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?

The Electromagnet releases the disk.

The Dashboard reports the disk being released.

The Electromagnet picks up the disk.

Describe what the VR Robot will do in this project.

Which two sensors are being pointed to on the VR Robot?

The Front Eye and Down Eye Sensors.

The Left and Right Bumper Sensors.

The Electromagnet and Location Sensors.

The Distance and Front Eye Sensors.

What value will the Boolean block report when the Eye Sensor is close to an object that has detectable colors?

It will report how far in millimeters (mm) or inches the Eye Sensor is from the object.

It will report the location angle of the VR Robot in degrees.

What value will the Boolean block report when the Eye Sensor detects a different color than the one that was selected?

It will report the time elapsed of the project in seconds.

It will report the current heading in degrees of the VR Robot.

Describe how the VR Robot is using the Down Eye Sensor in this project.

To identify when the VR Robot is above a blue disk.

To measure the distance to the blue disk.

What will happen when the Front Eye Sensor detects red in this project?

The VR Robot will stop driving.

The VR Robot will turn left for 90 degrees.

The VR Robot will drive forward.

The VR Robot will check the Front Eye Sensor repeatedly.

What is the purpose of having multiple [If then] blocks in this project?

To have the Front Eye Sensor check for each color and have the VR Robot perform a discrete behavior depending on the color detected.

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.

In this project, if the condition of the Down Eye detecting red is TRUE, how will the VR Robot move?

It will turn right for 115 degrees.

It will turn left for 115 degrees.

Describe why a [Forever] block is used in this project.

To continuously check if the VR Robot is near an object with detectable colors.

To continuously check if the VR Robot Pen is up or down.

To draw the color blue with the VR Robot Pen.

To report if the Bumper Sensors are being pressed.

What condition will be checked next if the condition of the Front Eye Sensor detecting blue is FALSE?

The condition of the Front Eye Sensor detecting red will be checked.

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.

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.

The goal of this challenge is to navigate the VR Robot through the Disk Maze and stop at the red Disk. Which of the following could be added to this project in order to solve the Disk Maze challenge?

If FrontEye detects red then Stop.

If the Front Eye Sensor detects blue then stop.

If the Down Eye Sensor detects purple then stop.

Wait until the Front Eye Sensor detects red.

Which of these best describes a programming language?

A set of rules where symbols represent actions.

A set of spoken commands for a robot.

An action performed by a robot.

A list of behaviors the robot already completed.

How do you change the behavior of the VR Robot?

Change the programming blocks called commands.

Change the programming language.
