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,” you’ll most likely imagine a program that works like this:
- If the color sensor detects black (meaning the robot is over the line), the robot moves forward.
- If the color sensor detects a different color (meaning the robot is not over the line), the robot turns toward the line.

FLL 2017: Attachment The Manhole Cover (08th) Mission
We have to admit. This is quite an interesting missions. There is a Manhole cover and it must be turned upside down. Well, the robot must turn it. Again LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro is used as a base for the Robot.

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.
