VEX Code VR U3&4

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

2. What is the first step in coding the VR Robot to draw a red line?

• Drag the [Set Pen color] block into the workspace and use the drop-down menu to set the color to "red".
• Drag the [move robot pen] block into the workspace and use the drop-down menu to set the position to "up".
• Drag the [Turn for] block into the workspace and set the parameter to "200 millimeters (mm)".
• Drag the [Set Pen color] block into the workspace and use the drop-down menu to set the color to "blue".

3. 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.

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

• Decimal values.
• Negative values.
• Words or text.
• Integers

5. 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.

6. 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).

7. When will the VR Robot move the VR Pen up?

• Before the [Repeat] block has repeated all of the blocks inside of it twice.
• Before the VR Pen is set to the color red.
• After the [Repeat] block has repeated all of the blocks inside of it six times.
• After the [Repeat] block has repeated all of the blocks inside of it twice.

8. The following project was created to draw a house, but it is unfinished. Which of the following blocks should be used next to begin drawing the roof of the house?

• [move robot pen] block set to "up"
• Drive for block set to 2000 millimeters (mm)
• [Repeat] block set to six
• [Turn for] block set to 135 degrees

9. Which block reports if the Bumper Switch is pressed?

• <Pressing bumper>

• <Distance found object>

• <Color near object>

10. What values does the block return?

• TRUE (pressed) or FALSE (released).
• Positive (pressed); Negative (released).
• Number values between one and ten.
• Distance from object in millimeters (mm).
