EV3 loops

What sensor is being used in this program?

• Color Sensor
• Touch Sensor
• Ultra Sonic Sensor
• Gyro Sensor

A programming command that allows a computer to repeat a code sequence.

• Loop
• Color
• Robot
• Code

This picture is an example of a:

• Switch
• Loop
• IF Then Statement
• Go go

When this program is executed (started), how many times would the robot robot's wheels turn?

• 1 time

• 30 times

• Until someone turns if off

• 50 times

Repetitive tasks can be accomplished efficiently by:

• Writing very long programs

• Writing multiple programs

• Repeating behaviors within a program

• Manually controlling the robot

What does the Loop do?

• Send the program "flow" back to an earlier point in the program, causing it to repeat some instructions

• Choose between two different possible sets of commands to run

• Switch to a branching decision quickly, to enable continuous control of the robot

• Run all the programs on the robot in a continuous cycle

How do you add a Loop to a program?

• Click the Loop Block, then drag a box around the commands you want to put inside the Loop

• Select the blocks you want to put inside the Loop, then right-click and choose "Place in Loop"

• Right-click in an empty area and choose "Make Loop" from the menu that appears

• Drag a Loop into the program, then drag commands into it

A Loop set to Count Mode will send the Program Flow back...

• Every time, forever

• Only a limited number of times

• If the Touch Sensor is not pressed when the Flow reaches the end of the Loop

• If there is nothing after the Loop

What does it mean for a Loop to be "Conditional" in the EV3 Programming Software?

• It only sends the Flow back under certain conditions

• The entire Loop can be skipped under certain conditions

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

• The code runs every time, no matter what

What is the "condition" in this Loop based on?

• The distance the robot has traveled

• The value of the Touch Sensor

• The number of times the Loop has sent the Flow back

• The number of seconds the Loop has been running
