LEGO MINDSTORMS EV3

This robot has a color sensor and this sensor is used for following lines. Additional Mindstorms EV3 sensors could be place on the robot, like a Gyro sensor or a second Color sensor.

This is a short list with good practices and useful tricks that competitors in FLL can use.

The tasks for the color sensor could be accomplished with a waiting block or with a loop block. Should you force one solution or the other?  

You've seen the gyro sensor. It has two arrow. How does it work? What does it do?

Try to build the attachment following the instructions. Use it to actually solve a mission from any competition (like taking loops)

Explanation and demonstration of the big task for the lesson.

In some cases we may want to use the switch block as a simple if-clause: execute the given action only if the condition is met, otherwise do nothing. Other times you may have some nested switch blocks that make the program too big to be shown on one screen. In both cases using tabbed view may be handy.
