FLL Competition Introduction. Border align with NXT
Positioning your MINDSTORM robot precisely on the FIRST LEGO League competition field is one of the first things you should learn while preparing. In this video tutorial, we will show three different attachments you could use when aligning to the walls of the competition table. We will show other ways and attachments in some of the next videos.

Light sensors cover on LEGO Mindstorms NXT robots
In this video we are solving one of the most important challenges on the FIRST LEGO League competition, i.e how to cover your Mindstorms NXT light sensors so that they are not affected by outer light sources at the day of the competition. Once again you would find 3 solutions and more will come in the next videos.

Work of the LEGO Mindstorms NXT rotation sensor
This lesson shows how you could use the rotation sensors of the motors of a LEGO MINDSTORMS NXT robot. This technique is very powerful during the competition. We give ideas on how to show the value of the sensor on the display, how to check if you have completed a given job or you are still doing it and other even more advanced topics. Understanding the rotation sensor is a must if you want to use the full capabilities of the motors.

Bult Bot - One Step Motor Attachment LEGO Robot
In all building instructions for LEGO robots it is important to have the motors attached to the brick in more than one place. In the following construction, there is a beam connecting the two motors which has exactly this purpose. It makes the construction much more stable. Try removing this beam for example and see what will happen. Would the robot be able to move?
Many different types of wheels could be used. Both NXT and EV3 or from other LEGO technic series.

Andy Roid Bot - Angled Back Motors Attached LEGO Mindstroms Robot
Building instructions for a LEGO Mindstorms EV3 robot base. The attachment of the motors is quite interesting. We follow the angles of LEGO technic to attach them. This construction has some difficulties turning to the left and to the right. But if you have to take on an obstacle that high this is one of the options.
You can use all kinds of wheels on this robot - EV3, NXT or others. It doesn't actually matter.

Spark Bot - Underside Motor Attachment LEGO Robot
It sparks. It's sparkling. Well, the goal of this LEGO Mindstorms building instruction is to spark the imagination when the base of the construction is very simple. Just two motors with the brick above them and one of the most classic ways to attach them together - with angled beams.
The construction could use EV3 or NXT wheels, so chose wisely. As a robot chassis base, it is suitable for all kinds of extensions. An interesting thing is the motors are attached to each other with a frame which is getting very popular in the EV3 world.

Spy Bot - LEGO Mindstorms EV3 Robot used as a spy
"Bot. Spy Bot."
Many of us are fascinated by the idea of spies. Movies for "spies" are also very popular and if you haven't watched them check out the 007 movies. These here are building instructions for a LEGO Mindstorms robot with two touch sensors and one ultrasonic. It could be used as a spy - sneaking closer to you and detecting if you move or if you touch it. The whole idea for this robot came from NXT when there were sound sensors. Currently, there are no sound sensors in the EV3 set, but the robot could again be quite fun to program.

Chain Monster - a SPIKE Prime Box Robot commanding the attachments with chains
We took a stab at building a box robot entirely with chains. It is difficult to find these chains. They were part of the original LEGO MINDSTORMS NXT Robots, but we had an idea. Can we power the whole box robot and all the attachments with the chains. This allows us to do a nice demonstration when and how chains could be used.
To build the robot you will need about 180 of these the chain pars - 3711a. They could be found from NXT and from some technic sets.
This robots require additional parts on top of the LEGO Education SPIKE Prime and LEGO Education SPIKE Essentials. Check out the additional parts required.

How to measure the speed of the robot
A human being walks with an average speed of about 5 km/h (3 miles/h). In this video tutorial we will develop a block for LEGO MINDSTORMS EV3, that measures the speed of the robot in distance/time units where time will be configurable and could be 1 second or 0.5 seconds or any other number of seconds you pass as a param to the block. Measuring the speed of the robot is very powerful if you start building an Artificial Inteligence for your robot and is quite fun :)
