Virtual Robotics Quiz Day-2

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

• • True

• • False

Answer explanation

• The Distance Sensor can be used to avoid or find a wall or object. 

• Using the Distance Sensor will allow a VR Robot to drive up to an object without touching it. This can be helpful in navigating a maze without continuously bumping into the walls, to avoid an object or to drive to an object or wall in the VEXcode VR Playgrounds.

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?

• 
• 
• 

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

• True

• False

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

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

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

• 1. To navigate to specific coordinates of the Playground.

• 1. To detect the color of an object.
