A robot a 'day'. Finish the construction yourself. Attach wheels
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.

Crossed lines (T Sections). Positioning. Part 1.
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.

Keeping a straight line using a gyro sensor.
The gyro sensor indicates the angle of the turn the robot made. We certainly can use this to create a robot that could perfectly follow a direction, right? Now we'll show you the easiest way to do it.

Line Following 101
When you hear the task "program the robot to follow a black line", most probably you will imagine a program operating as follows:
- if the color sensor reads black (hence the robot is over the line), the robot goes forward;
- if the color sensor reads some other color (hence the robot is not over the line), the robot turns towards it.

Pinless Flywheel and Rubber band attachement for LEGO Mindstorms robots
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.

Ultrasonic Sensor. Simple follow a wall (part 1)
This tutorial is about how to follow a wall with an ultrasonic sensor. The example is with a border from a FIRST LEGO League (FLL) competition, but could also easily be applied to other competitions and problems.
