Robotics I Unit 3 Test Review

When would be an appropriate time to use loops in a program?

• If you want a task completed just once

• If you want a task to be completed multiple times

• If you need to change the velocity for different commands

• If you need to change the duration of different commands

What does it mean for a loop to be "conditional"?

• It only sends Program Flow back under certain conditions

• The entire loop will run faster than the rest of the blocks in the program

• The loop runs faster after it is trained, or "conditioned"

• The code runs every time, no matter what

What happens in Program Flow when a condition in a "repeat until" block becomes true?

• The robot ends the program immediately

• The robot continues to repeat the loop

• The robot skips all of the block within the loop and moves on in the program

• The robot executes the blocks within the loop but skips the rest of the program

When does the "repeat until" block check the sensor?

• Continuously while inside the loop

• At the beginning of the loop

• At the end of the program

• At the end of every block within the loop

According to the program below, how many times will the TouchLED turn blue?

• 2

• 4

• 5

• 6

What will the robot do if it does not sense an object within 200 mm?

• Set the TouchLED to yellow

• Turn right

• Pring "Done" on the Brain

• Move forward for 300 mm

True or False: If the condition of the loop is false in a program with a looped decision, Program Flow will skip the loop and continue with the rest of the program.

• True

• False

A robot will run the code in the "if branch" only if...

• The condition is True

• The condition is False

• The condition is neither True or False

• It will run no matter what

True or False: The condition of an "if-then-else" block is checked many times, even when not placed inside a loop.

• True

• False

Placing an "if-then-else" block inside a loop is a common technique often used to...

• Repeat a sequence of movements in exactly the same way many times

• Choose between two "branches" of code

• Repeat a decision multiple times

• None of the above
