VexVr Navigating a Maze

Which of the following describes how the Bumper Sensor works in a VEXcode VR project?

• Senses if an object is a certain color.

• It is a switch that reports if it is pressed or released.

• Moves the VR Robot forward or backwards a specific distance.

• Turns the VR Robot left or right a specific amount of degrees.

When pressed, the Bumper Sensor returns a value of 1.

• True

• False

What will happen when the Bumper Sensor is pressed in this project?

• The VR Robot will stop driving.

• The VR Robot will reach maximum velocity.

• The VR Robot will drive forward.

• The VR Robot will drive in reverse.

Which kind of block is the <Pressing bumper> block?

• "C" block

• Stack block.

• Boolean reporter block.

• Hat block.

Which of the following is the best reason to use the Bumper Sensor?

• To instruct the VR Robot to report the distance of the nearest object in order to avoid a collision.

• To instruct the VR Robot to use information from its environment (e.g Did I collide with a wall?), and then make decisions based on that information (e.g. Stop when it collides with a wall).

• To report the velocity of the VR Robot in order to complete a task more quickly.

• To set the Pen position to down in order to track the path of the VR Robot.

Which statement is TRUE for non-waiting blocks?

• They allow the stack to continue even if the block's behavior is not yet complete.

• They pause the rest of the stack until that block's behavior has been completed.

• They cause the VR Robot to shut down.

• They are always blocks from the Looks category.

What do waiting blocks do in a VEXcode VR project?

• Repeat a behavior forever.

• Pause the stack until that block's behavior has been completed.

• Allow the stack continue even if the block's behavior is not yet complete.

• Set VR Robot Pen color to red.

How does the highlighting function help to visualize waiting vs. non-waiting blocks?

• It explains how to use waiting and non-waiting blocks.

• It stops the project when a waiting block is being executed.

• It moves blocks to show how the project is being executed.

• It highlights each block as it is being executed in a VEXcode VR project.

Which of these blocks can NOT be used as either a waiting or non-waiting block?

• [Stop driving]

• [Drive for]

• [Turn to heading]

• [Turn for]

Which of the following best describes how to create a project where the VR Robot drives forward until the Bumper Sensor is pressed?

• Select the [Drive] block, then place the [Turn for] and <Pressing bumper> blocks underneath.

• Select the [Drive] block, then place the [Wait until] block underneath. Place the <Pressing bumper> Boolean reporter block inside the hexagon in the [Wait until] block.

• Place the [Repeat until] block with the <Pressing bumper> Boolean after the [Drive] block.

• Place the [Drive for] block under the [When started] block. Add the <Pressing bumper> and the [Set drive heading] blocks.
