S Block

What behavior will the VR Robot perform if the condition of the Left Bumper Sensor being pressed is TRUE?

• The VR Robot will continue to drive forward forever.

• The VR Robot will drive in reverse for 50 millimeters (mm) and then turn left for 90 degrees.

• The VR Robot will stop moving.

• The VR Robot will drive forward for 50 millimeters (mm) and then turn right for 90 degrees.

Which of the following Boolean blocks should be used in the [Repeat until] block to check if the VR Robot's Down Eye Sensor detects red so the VR Robot does not fall off of the Playground?

• The <Near object> block

• The <Pressing bumper> block

• The <Color sensing> block

• The <Drive is done> block

Which of the following best explains why a [Repeat until] block was used in this project instead of a [Wait until]?

• Using a [Wait until] block would block the project flow. The VR Robot would be waiting until the Down Eye Sensor detected red before doing anything else. This would cause the VR Robot not to move.

• Using a [Wait until] block allows the robot to drive forward for 300 millimeters (mm) and then turn right for 90 degrees, forever.

• Using a [Wait until] block allows the condition of an object being detected to be constantly checked. This allows the VR Robot to drive toward an object when it is detected and turn if not.

• Using a [Wait until] block allows the conditions of the [If then else] block to be skipped. This allows the project flow to execute much faster, as the condition of an object being detected only need to be checked once in the project.

This project was used to knock all buildings off of the Dynamic Castle Crasher Playground, but it does not work correctly. Which of the following best describes the error in this project?

• The Down Eye Sensor should detect the color blue instead of the color red.

• An [If then else] block should be used instead of a [Wait until] block, because the [Wait until] block is blocking the flow of the project.

• The <Distance found object> block should be replaced with a <Pressing bumper> block.

• The [Forever] block should be removed.
