chap 4/5

Which of the following is the best example of something the Distance Sensor can report?

• The location angle of the VR Robot.

• The color of a disk.

• The distance between the front of the Distance Sensor and an object.

• The current heading of the VR Robot.

Which of the following best describes how the Distance Sensor works?

• The Distance Sensor uses the time it takes for a pulse of laser light to reach an object from the sensor.

• The Distance Sensor uses the time it takes for laser light 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 laser light to bounce off ONLY yellow and orange objects and return to the sensor.

Which of the following best describes what the greater than operator reports?

• If the first value is larger than the second value.

• If the first value is less than the second value.

• If the first value and the second value are equal.

• The first value

Which is an advantage of being able to monitor Distance Sensor values in the Dashboard when running a VEXcode VR project?

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

• Allows the user to control what is happening in a VEXcode VR project.

• Allows the user to see what is happening in the Playground Dashboard.

• Allows the user to see a breakdown of each VEXcode VR project step.

Which units does the get_distance command report the distance of the nearest object in?

• Meters and Inches

• Centimeters and Feet

• Millimeters and Inches

• Millimeters and Feet

Which of the following is a common use of the Location Sensor?

• To detect the color of an object near the sensor

• To pick up disks on a Playground

• To determine the current heading of the VR Robot

What does using comments in a project allow users to do?

• Launch the Playground window.

• Describe parts of their project for other users.

• Attach .vrblocks files.

• Open example projects.
