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 VR Robot if pressed.
  To measure the distance between fie front of the Distance Sensor and the object
• To report the current heading of fie VR Rob«

Which of the following describes how the Distance Sensor works?

• The Distance uses the tine 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 to reach all objects in the Playground.
• The Distance uses the tine it takes for ultrasonic waves to bounce off yellow and orange objects and return to the sensor.

Which of the following describes what the <Greater than> block reports?

• If the first value is larger than the second value
• If the first value is less than fie second value.
• If the first value and the second value are equal.
• TIE first value.

Which of the following describes what the Distance Sensor reports?

• The time it takes the VR 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> black 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 fie VR Robot has until it reaches an object.

U ovom 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 [(Dive for block is missing.
• A <Greater Than> black was used instead of a <Less Than> Block
• A [Turn for] block was used instead of [Tyco] black.
• A [Turn to rotation] block is missing.

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

• Allows the user to see what is happening in a VEX code VR project in real time
• Allows the user to control what is happening in a VEX code VR project.
• Allows the user to see what is happening in fie Playground Dashboard.
• Allows the user to see a breakdown of each VEX code VR project step.

Which of the following describes how the VR Robot will move in this project?

• The VR Robot WII start driving and stop when the Distance Sensor is greater than 150 millimeters (mm) away from an object.
• The VR Robot WII 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 WII drive forward, Sop, drive forward again for 150 millimeters (mm) then stop.

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

• Select and drag the (Position of Robot) block< to the Monitor Console icon in the Workspace.
• Select and drag the <Drive is moving> block to the Monitor Console icon in the Workspace.
• Select and drag the <Color near object> block to the Monitor Console icon in the Workspace.
• Select and drag the <Distance found object> or (Distance from) block to the Monitor Console icon in the Workspace!

Which of the following describes why the VR Robot will not move in this example project?

• The 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 rather 150 millimeters mm
• The VR Robot will immediately crash into a wall if it moves.

What values does the <Distance found object> block report?

• TRUE or FALS
• Uključeno ili Isključeno.
• Da ili Ne.
• Zero or One.

Which of the following best describes what the <Less than> block reports?

• If tie first value is less than fie second value
• If tie first value is larger than the second value.
• If the first value and the second value are equal.
• The second value.

What units does the (Distance from) block use when reporting values?

• Inches and centimeters.
• Meter and millimeters (mm).
• Meter and inches.
• Millimeter’s(mm and inches)
