What is the first step in coding the VR Robot to move the VR Pen down to draw a black line?

• [Drive for] block set to 2000 millimeters (mm).

• Drag the [move robot pen] block into the workspace and use the drop-down menu to set the position to "down".

• Drag the [Turn for] block into the workspace and set the parameter to "400 millimeters (mm)".

• Drag the [move robot pen] block into the workspace and use the drop-down menu to set the position to "up".

How many times will the [Repeat] block repeat the [Turn for] and [Drive for] blocks inside of it?

• Only once.

• Two times.

• Three times.

• Four times.

How do you build a program in Vex VR?

• Drag code blocks onto the workspace grid

• Double click the code blocks

• Upload programs from the teacher website

What types of values can the [Repeat] block accept as parameters?

• Decimal values.

• Negative values.

• Words or text.

• Integers.

How do you "run" your program?

• Click the "Start" button

• Click the "Playground" button, then the "Start" button

• Click the yellow "When Started" block on the workspace grid

What is the condition that will end this [Repeat] block?

• After the VR Robot places the pen down.

• After the VR Robot drives forward one time for 200 millimeters (mm).

• After the [Repeat] block has repeated the blocks inside of it four times.

• After the VR Robot has driven forward 200 millimeters (mm) then turned right 60 degrees six times.

How can you view the text version of your program?

• Click the "< >" code symbol

• Download the program and run it from a different application

• You can only see block code right now

How can you save your programs?

• File/Save To Your Device

• The website saves your programs automatically

How can the following example be simplified by using a [Repeat] block?

• By placing the [Drive for] and [Turn for] blocks in a [Repeat] block that repeats four times.

• By placing the [Drive for] block in a [Repeat] block that repeats four times.

• By placing the [Turn for] block in a [Repeat] block that repeats four times.

• By changing all of the parameters of the [Drive for] blocks to 400 millimeters (mm) instead of 200 millimeters (mm).
