Front

Which of the following is the best description of what the Distance Sensor does in a project?

Back

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

Front

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.

Back

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

Front

Which of the following best describes what the block reports?

Back

If the first value is larger than the second value.

Front

Which of the following best describes what the Distance Sensor reports? 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.

Back

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

Front

Which of the following is the best description of what a block reports while inside of a [Wait until] block? Options: If the distance is a large number., The total time needed to run the project., A TRUE or FALSE value., The total time the VR Robot has until it reaches an object.

Back

A TRUE or FALSE value.

Front

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.

Back

A block was used instead of a Block.

Front

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

Back

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

Front

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.

Back

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

Front

How can you monitor the value of the Distance Sensor in the Monitor Console?

Back

Select the checkbox next to the or (Distance from) block.

Front

Which of the following describes why the VR Robot will not move in this example project? Options: The distance between the Distance Sensor and the object is less than 150 millimeters (mm) away. The Eye Sensor is reporting the color red. The distance between the Distance Sensor and the object is greater than 150 millimeters (mm) away. The VR Robot will immediately crash into a wall if it moves.

Back

The distance between the Distance Sensor and the object is greater than 150 millimeters (mm) away.
