2.1.4 - 2.2.3 Review Open book

What is the primary purpose of a while loop in programming?

• To execute code only once
• To execute code a fixed number of times
• To execute code as long as a condition remains true
• To execute code regardless of any conditions

In the Castle Crasher activity, what is the main goal of the programming task?

• To create the fastest possible robot
• To create an algorithm for finding and knocking down castles within boundaries
• To program the most complex code possible
• To create multiple robots simultaneously

Which sensor option is NOT mentioned as a way to keep the VR-SDV from going over the edge?

• Using DownEye to detect red
• Using FrontEye to detect red
• Using grid coordinates tracking
• Using distance sensors

What is the purpose of the 'not' block in the programming activity?

• To make the program run faster
• To create an infinite loop
• To get the opposite of whatever is put inside it
• To stop the program immediately

In the context of the activity, what does the DownEye sensor detect to keep the robot within bounds?

• Blue boundaries
• Green boundaries
• Red boundaries
• Yellow boundaries

What type of loop is used to create an infinite loop in the activity?

• For loop
• Do-while loop
• Forever loop with nested while loop
• Switch loop

What is the primary purpose of input devices in a programming system?

• To display output information
• To provide environmental information for decision-making
• To store program data
• To control robot movements

What happens when the "stop driving" command is removed from the robot's program?

• The robot immediately stops
• The robot continues executing its last drivetrain instruction
• The program crashes
• The robot returns to start position

Which sensor does the VR-Bot use to detect markers ahead of it?

• DownEye sensor
• FrontEye sensor
• SideEye sensor
• UpEye sensor

What is the main advantage of using loops and conditionals in the Disk Maze program?

• It makes the program run faster
• It reduces repeated code
• It improves sensor accuracy
• It increases robot speed
