• LEGO MINDSTORMS EV3

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 :)

"Array initialization" is the first step in every program that involves Arrays. This applies to most programming languages and for EV3-G it is a must. 

In this tutorial, we would show you how to initialize the array and how to extract this logic in a new block

It this episode we would present you with our attachment for lifting the robot. 

Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.

Before moving forward here is the simple task of building the mechanism and extending the legs. Extend the legs to fifteen LEGO units. 

We would continue from the previous program where we used variables and we would change this to arrays.

We will introduce a convention, an agreement, how and in which cases we are going to use each types of blocks.

How to align the wheels and how much should you push for this solution?

We would look at the rules of the competition over our small model and we would start solving the field.

What is the end result? - have the attached on the mission model. What is the mechanism the would make the robot hang on the mission model.

This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M04. CRATER CROSSING. These are some of the funniest missions at this robotics competition. Try to move over an obstacle with a robot and if you manage to return back to base without bumping into other mission models that would be great. 

There were a few problems with the 40 teeth gears that we were using. Let's list some of them

This video tutorial shows how the LEGO Mindstorms EV3 Ninja Motorcycle robot works. It's a nice demonstration with the robot moving forward, backward, and slightly to the left and right. 

Building a rack is a very important skill during competitions. You should try to build one, learn how to use it and have it as a tool for you next robots. But for this particular BoxRobot, we will not continue with a rack.

The most stressed wheel in our system is the driven wheel. We've already fixed the problem with the driving wheel of the scissor mechanism and now it is time to look at the drive LEGO Mindstorms wheel. 

We are programming this strange construction to move in a square. This is a basic task, but it is worth doing for a robot with motors placed in different directions.

The M08. AEROBIC EXERCISE is one of the very common types of mission in FIRST LEGO League robotics competitions. I think this pattern of missions was first introduced with the growing abilities of the participating students that were constantly reaching the maximum number of points. So the competition introduced mission that require a lot of time - 20-30 seconds, are time consuming and are complex. They requires a lot of moves. This here is a video tutorial on how it could be accomplished

Think of an attachment that leaves the Gecko on the mission model. Don't use the robot attachment that we already have. Just the box robot and the gecko. Nothing should support the Gecko when it is hanged on the mission model.
