VEXcode Unit 5 Quiz

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

• 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.

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

• 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.

Which of the following best describes what the <Greater than> block 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 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.

Which of the following is the best description of what a <Less than> block reports while inside of a [Wait until] block?

• 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.

True or False: The Distance Sensor reports the total distance the VR Robot travels.

• True

• False

True or False: The Distance Sensor determines distance by using the time it takes for ultrasonic waves to bounce off of an object and return to the sensor.

• True

• False

Which block reports if the Distance Sensor has found an object?

• <Pressing bumper> block.

• (Distance from) block.

• <Distance found object> block.

• <Color near object> block.

The (Distance from) block reports the distance of the nearest object in meters and inches.

• True

• False

Which of the following is an advantage to using the Distance Sensor in a VEXcode VR project?

• To complete a maze without continuously bumping into the walls.

• To pick up and drop metal disks with metal cores.

• To navigate to specific coordinates of the Playground.

• To detect the color of an object.
