How do you detect a cross-section and move from following the main line to following the crossing line. In this series of video tutorials we are starting with a very simple solution that could work in most of the cases. It is especially useful for the FIRST LEGO League Trash Trek competition where there is such a section.
Next important state is Turn Right with our robot. This happens when we detect a line on the right.
There are constructions, especially on our platform, that you could build partially and then experiment with different ways to complete them. This is a very good exercise for creativity. It is sometimes difficult to build a whole robot from scratch, but finishing the robot with a few wheels and attachments is doable.
Now we are going to focus on a well-known block but set differently.
In this lesson we are going to focus on the yellow palette of blocks and see how the rotation sensor reset blocks functions.
Kiril Mitov's most favourite attachment. To quote him "I had a really great fun building this attachment and recording the videos for it".
It's an attachment with a Rubber band and a Flywheel and a Gear Wheel and a Worm Gear. So much knowledge in just one small attachment. The goal of the attachment is to be able to have an active attachment without actually having a motor. So you can place that attachment and it will do the work for you instead of using a motor to power it.
Build with LEGO Mindstorms EV3 set.

When you hear the task "program the robot to follow a black line", most probably you will imagine a program operating as follows:
