The Department of "throwing" is ruled by rubber bands. Impulsive power release in a short amount of time. In this video we are building an attachment that throws a ball and accomplishes the FIRST LEGO League 2012 bowling competition.
Let's try to integrate more of the things we have learned into a single attachment. One that could accumulate energy, conserve it and use it at the appropriate time. All this because of a Rubber Band and a Flywheel - and if you don't know what a flywheel is you should definitely watch this videos
In this video tutorial we experiment with different ways of solving the sports mission for throwing the ball. We show seven different LEGO MIndstorms EV3 and NXT robot constructions and attachements. Most of the techniques could be applied for any mission involving throwing a ball or an object.
We will take a look at the EV3 motors and will go into details about them
In this episode we build a reusable attachment for a LEGO Mindstorms EV3 robot that changes gears orientation and direction. It is one of the most useful attachments that you could use to move levers up/down and right/left. Adding the attachment on the robot takes 2-3 seconds and shows a very useful general principle of how to build reusable attachments.
We are showing the first way we could position the motors on the robot construction. This seems to be challenging for many robot builders and that's why we are going to do it in a few different ways in the next few video tutorials from the series.
The third robot has the brick and motors placed vertically. This is quite unusual and difficult, but the construction is very powerful because it saves space.
Cable management is very important on each competition. Cables could get in the way of attachments, levers, different wheels and so on. Brick accessibility is also very important. Do not forget that the brick should be charged from time to time and that you should also be able to access the buttons.
The FIRST LEGO League competition is similar each year. With a little experience you could accomplish most of mission. The goal of this episode is to introduce you to the course, its purpose and approach.
How great is the great attachment for lifting that we built in this course? How many times can it lift the robot without making an error? How great are your attachments and how could you test them? - the answer is simple. Just try 10 times and they should work at least 9 of them as our attachment is.
In this video tutorial we look at Vertical Lift Attachments. The attachment, the root and the mission model are all build from LEGO MINDSTORMS Robot Inventor 51515 set. We've found that vertical lift attachments that could lift missions models vertically could be quite useful for FIRST LEGO League competitions. This attachment is one of the more complex attachments and some say it has an "eye opening" mechanism as you can learn so much from it. It uses gear wheels and two levers connected to those gear wheels to lift a part vertically.
This tutorial demonstrates how we accomplish 5 missions in a row with a single robot and three attachments. This is a true multiple missions run for the FIRST LEGO League 2022-2023 SUPER POWERED. We Drop parts, we pull from the Smart grid, we push a lever, we collect a few energy units and we deliver the dinosaur toy.
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.
In this lesson I would like to show you how to build a LEGO Mindstorms competition robot and tell you how we have designed the construction used in the videos so far. Surely it isn’t perfect, but it is a good start.
This is one of the very interesting attachments by the ELM team. It is using rubber bands and some rubber to precisely drop the chicken. Very interesting way. Check it out and try to learn from it.
