Unit 5 Quiz

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.

Which of the following blocks is a Boolean block that reports if the first value is larger than the second value?

• <Less than> block.

• <Greater than> block.

• (Random) block.

• <And> block.

Which of the following blocks is a Boolean block that reports if the first value is less than the second value?

• (Round) block.

• <Or> block.

• <Greater than> block.

• <Less than> block.

Which of the following describes that the VR Robot will drive forward until the value of the Distance Sensor is less than 150 millimeters (mm)?

• Drive forward for 150 millimeters (mm).

• Drive forward until the Distance Sensor is greater than 150 millimeters (mm) away from an object.

• Drive forward until the Distance Sensor is less than 150 millimeters (mm) away from an object.

• Drive forward, stop, drive forward again for 150 millimeters (mm).

Which of the following describes a benefit of monitoring sensor values in a VR Project?

• Provides example projects for users.

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

• Allows the user to type messages to the VR Robot.

• Shows the user how to send a VR Project to a friend.

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.
