Drive Forward until Left Bumper is pressed, Turn right for 90 degrees, Drive Forward until Left Bumper is pressed, Turn Left for 90 degrees, Drive Forward.

Which is NOT a reason to use a condition in a VEXcode VR project? Options: To utilize sensors in a project., To control the flow of a project., To create the best way for the VR Robot to run properly in a specific playground., To instruct the VR Robot to perform different behaviors depending on the conditional values that are reported.

To control the flow of a project.

Where is the "Step" function located on the VEX VR interface? Options: In the File menu., In the Monitor Window., On the Dashboard., In the toolbar between the "Start" and "Stop" buttons.

In the toolbar between the "Start" and "Stop" buttons.

Which of the following is NOT a reason to use the "Step" feature? Options: To allow the user to observe a program and behaviors, one block at a time., To step backwards through a project., To trace the flow of a project in order to find and fix problems., To visualize which blocks are being executed at a given moment.

To step backwards through a project.

This project was used to drive the VR Robot from Start to the number '1' in the Wall Maze Playground, but does not work correctly. What is the error?

The last [Turn for] should be right instead of left.

Which of the following is the best description of the [Drive for] block? Options: Moves the VR Robot backward indefinitely., Moves the VR Robot left or right., Moves the VR Robot forward or backwards a specific distance., Moves the VR Robot forward indefinitely.

Moves the VR Robot forward or backwards a specific distance.

How can you make the VR Robot move in reverse on the [Drive for] block?

Changing the "forward" parameter to "reverse".

Which of the following is the best description of what the Distance Sensor does in a project? Options: To report the location angle of the VR Robot., To change behaviors of the VR Robot if pressed., To measure the distance between the front of the Distance Sensor and the object., To report the current heading of the VR Robot.

To measure the distance between the front of the Distance Sensor and the object.

Which of the following best describes how the Distance Sensor works? Options: The Distance Sensor uses the time it takes for ultrasonic waves to reach an object from the sensor., The Distance Sensor uses the time it takes for ultrasonic waves to bounce off of an object and return to the sensor., The Distance Sensor uses the time it takes for the VR Robot to reach all objects in the Playground., The Distance Sensor uses the time it takes for ultrasonic waves to bounce off yellow and orange objects and return to the sensor.

The Distance Sensor uses the time it takes for ultrasonic waves to bounce off of an object and return to the sensor.

Which of the following best describes what the block reports?

If the first value is larger than the second value.

Which of the following best describes what the Distance Sensor reports? Options: The time it takes the VR Robot to travel around the entire playground., The distance between the VR Robot and the Distance Sensor., The distance between the VR Robot and the nearest solid object., The total distance the VR Robot travels.

The distance between the VR Robot and the nearest solid object.

In this example project the VR Robot should get to the number "2" in the Wall Maze, but it does not. Which of the following describes the error in this project? A [Drive for] block is missing., A block was used instead of a Block., A [Turn for] block was used instead of [Turn] block., A [Turn to rotation] block is missing.

A block was used instead of a Block.

Which is an advantage of being able to monitor sensor values in the Monitor Console when creating VEXcode VR projects?

Allows the user to see what is happening in a VEXcode VR project in real time.

Which of the following describes how the VR Robot will move in this project? Options: The VR Robot will start driving and stop when the Distance Sensor is greater than 150 millimeters (mm) away from an object., The VR Robot will start driving and stop when the Distance Sensor is less than 150 millimeters (mm) away from an object., The VR Robot will drive 150 millimeters (mm) then stop., The VR Robot will drive forward, stop, drive forward again for 150 millimeters (mm) then stop.

The VR Robot will start driving and stop when the Distance Sensor is less than 150 millimeters (mm) away from an object.

How can you monitor the value of the Distance Sensor in the Monitor Console? Options: Select the checkbox next to the (Position of Robot) block., Select the checkbox next to the block., Select the checkbox next to the block., Select the checkbox next to the or (Distance from) block.
