Video tutorials, Courses, Materials and Programs

In this video lesson I am building a LEGO Mindstorms EV3 active attachment powered by a small gear wheel. The attachment could move up and down, it is very useful for collecting objects. It could easily be adapted and used on other robots.

We are making a parallel with Video Lesson 56 from the series and we are also showing ways to improve the stability of an axle which is most of the time neglected, but could lead to great problems.

How do you lift heavy objects with an attachment? In this episode we show a simple, interesting, but yet not very popular way to lift something heavy with and LEGO Mindstorms EV3 robot and without gears and motors as attachment. As a specific example we are using the Strength Exercise mission from the FIRST LEGO League 2012 competition. 

Here we continue examining FLL 2014 World Class missions. We show different ways, for putting the insert in place as well as taking the loop from the robotics arm. Some of them are quite specific, which reminds us, that you need to think out of the box, while solving the missions.

This time we stop on "Using the Right Senses" mission, or actually on how to solve the "Right Senses" mission without "Senses" (sensors). To achieve that we use the carabineer counstructed in one of the previous tutorials, of course after a small modification.

The robot attachment build in this tutorial gives an idea on how to release a rubber band at a specific moment using a motor. It's a simple, but yet powerful technique on using rubber bands. 

With this attachment we just share an idea. The attachment was build by an FLL team called Brother in Arms and they needed a way to turn two axles in different direction, one at a time. The attachment was not used in the final robot design and construction, but presents a nice idea.

With this series of videos we are looking at FIRST LEGO League 2013 Nature's Fury competition and we are building a robot for accomplishing some of the mission. It would be a tutorial with at least four parts and we are building a complex attachment that could catch, lift and release different parts with only one motor and rubber bands. Not one, not two, but three movements with only one motor. 

One attachment to rule them all...We have seen it and it works -> solving most of the competition models with only one attachment. In this video tutorial without programming we would walk you through the principles and methods of using a single attachment for most of the FIRST LEGO League competition models. One can learn alot from using as few parts as possible to solve as many missions as possible.

We show the principle of solving the next FIRST LEGO League (FLL) Nature's Fury 2013 competition missions. Again, without any programs, but just the principles of using one attachment for most of the missions.

Third, and last video of this series on how to use ONE attachment to solve the FLL 2014 World Class missions.

This is the oldest and most classic problem in the field of robotics. Shaft in an opening. Basically robotics and in improvement of many of the actuators is about improving the solutions to such problems. Let's see how we ca do this using a mission model from the FIRST LEGO League (FLL) competition.

Next robot construction for holding and releasing balls from this container. In this video we discuss the improvements and how to use the chains to release one ball at a time.

Improving the construction for the World Robotics Olympiad missions. The improvement is in the position of the sensor and the size of the balls container. 

In the video we improve on the robotics mechanism for pushing the different blocks out of the robot container. We continue from the previous video.

Many FLL competitions have a mission for demolition. You should always destroy something, but destroy it in a regulated manner and probably collect the destroyed mission model after that.
