This programming stack would cause the driving base to:

• Turn in 3 different directions.

• Move forward 2 rotations and backward 720 rotations then forward again.

• Move straight in 3 different ways.

• Turn left then right then left for 1 second.

This programming stack turns the Driving Base in

• 5 different ways.

• 3 different ways.

• to a straight line movement 3 ways.

• a large circle.

This programming stack

• turns the base in 8 circles.

• turns the base in 25 circles.

• turns the base 200 times.

• turns the base in 1 circle.

Answer explanation

This is 4 times a quarter circle turn WHICH USES 2 ROTATIONS so 4 quarter circles would be 4 x 2 = 8 rotations and that makes 1 circle!

This code stack would cause the base to

• Move forward then spin once.

• Move backwards in a circle.

• Move forwards in a circle.

• Move forwards in a square.

Answer explanation

To spin means to turn in the same spot.

Assuming that "right:100 for 171 degrees" causes the robot to turn 90 degrees like the corner of a rectangle, this code would cause the driving base to

• Move in a circle 4 times.

• Move in a a triangle.

• Move in a square.

• Circle left.

These types of codes are

• event headers - no code connects above them.

• controls - they control how long to wait.

• comments - they say what the code does.

• movements - they cause the base to move forward.

This icon shows

• that the driving base is connected.

• that the driving base is not working.

• that the driving base is not connected.

• that you need to connect in order to create a program.

These linked words (ALL CODEBLOCKS) at the bottom left of the EV3 interface open up to show

• a comment about all codeblocks.

• how the sensors work.

• what blocks don´t work.

• all the codeblocks that are available.
