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.
What will the VR Robot do when the Bumper Sensor is pressed in this project?
Turn right for 180 degrees.
Stop driving.
Turn right for 90 degrees.
Drive in reverse for 200 millimeters (mm).
What feature highlight blocks as they progress through the project execution?
The Step feature.
The Share feature.
The Tutorial Videos.
The example projects.
Why is it helpful to use the "Step" feature in a project?
Why is it helpful to use the "Step" feature in a project?
It allows you to track the time it takes to execute a project.
It allows the user to trace the flow of a project in order to find and fix problems.
It shows examples of how to correct problems in a project.
Where in the Wall Maze Playground will the VR Robot stop in this project?
Step 1
Step 2
Step A
Step B
How often will the [Wait until] block check a Boolean condition?
It will check repeatedly until the Boolean reports FALSE.
It will check repeatedly until the Boolean reports TRUE.
It will check once every minute until the project is complete.
It will check only once.
