Programming Language and VR Robot Worksheet

Which of these best describes a programming language?

• A set of rules where symbols represent actions.

• A set of spoken commands for a robot.

• An action performed by a robot.

• A list of behaviors the robot already completed.

What is the name for an action performed by the VR Robot?

• Command

• Behavior

• Parameter

• Programming Language

How do you change the behavior of the VR Robot?

• Change the programming language.

• Name and save your project.

• Change the programming blocks called commands.

• Change the Playground.

Refer to the code blocks shown in the diagram. Which of the following is the best description of what the VR Robot will do based on this project?

• The VR Robot will drive forward 1000 millimeters (mm) at maximum velocity. It will turn right 180 degrees and drive forward 1000 millimeters (mm).

• The VR Robot will drive forward 1000 millimeters (mm) at maximum velocity. It will turn right 90 degrees, set velocity back to the default, and drive forward 1000 millimeters (mm).

• The VR Robot will drive forward 1000 millimeters (mm) at maximum velocity. It will turn right 180 degrees, set velocity back to the default, and drive forward 1000 millimeters (mm).

• The VR Robot will drive forward 1000 millimeters (mm) at maximum velocity. It will turn left 180 degrees, set velocity back to the default, and drive forward 1000 millimeters (mm).

Why is it important to correctly sequence commands in a project?

• To make a project that works as intended.

• To make the VR Robot skip around to random commands.

• To have accurate values and parameters in commands.

• To make a project that does not work as intended.

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".

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.

Refer to the code block diagram shown. 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 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).

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.
