Which of the following is the best description of what the Eye Sensor does?
It reports the X,Y position of the VR robot.
It reports the distance between the VR robot and the nearest solid object.
It can be controlled to pick up and drop disks with metal cores.
It detects if there is an object present and if so, the color of that object.
Which two sensors are being pointed to on the VR robot?
Left and Right Bumper Sensors
Front Eye and Down Eye Sensors
Electromagnet and Location Sensors
Distance and Front Eye Sensors
What value will the <Eye Sensor near object> Boolean block report when the Eye Sensor is close to an object that has detectable colors?
It will report TRUE
It will report FALSE
It will report how far in mm or in the Eye Sensor is from the object
It will report the location angle of the VR robot in degrees.
What value will the <Color sensing> Boolean block report when the Eye Sensor detects a different color than the one that was selected?
It will report the time elapsed of the project in seconds.
It will report the current heading in degrees of the VR robot.
It will report FALSE.
It will report TRUE.
Describe how the VR robot is using the Down Eye Sensor in this project.
to draw on the playground
to measure the distance to the blue disk
to solve a maze
to identify when the VR robot is above a blue disk
What will happen when the Front Eye Sensor detects RED in this project?
The VR robot will stop driving
The VR robot will turn left for 90 degrees
The VR robot will drive forward
The VR robot will check the Front Eye Sensor repeatedly
In this project, if the condition of the Down Eye detecting RED is TRUE, how will the VR robot move?
It will turn right for 115 degrees
It will drive forward forever
It will turn left for 115 degrees
It will stop driving
In this project, how many times will the [Drive] block be repeated?
Forever
100 times
90 times
once
What condition will be checked next if the condition of the Front Eye Sensor detecting BLUE is FALSE?
The condition of the Front Eye Sensor detecting green will be checked.
The condition of the Down Eye Sensor detecting red will be checked.
The condition of the Front Eye Sensor detecting none will be checked.
The condition of the Front Eye Sensor detecting red will be checked.
Describe why a [Forever] block is used in this project.
To continuously check if the VR robot pen is up or down.
To continuously check if the VR robot is near an object with detectable colors.
To draw the color BLUE with the VR robot pen.
To report if the Bumper Sensors are being pressed.
