Accomplishing many tasks with a single attachment for the FIRST LEGO League (FLL) 2013 competition. The attachments are using many rubber bands. What is interesting is that it collects/lift/triggers many things at the same time. This is how you could save time and parts during a competition.
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.
The FIRST LEGO League Competition is divided in four categories. The Robot Design category is not as popular as the Robot Game, but still is 25% of the end result of a team. In this tutorial we will stop and make an overview of it.
Using a number of axles, beams and rubber bands we collect many loops at once. This is an important part of every competition, mostly of the FIRST LEGO League.
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.
Extend the previously build attachment for the FIRST LEGO League (FLL) Nature's Fury competition so that we can move the Truck and Ambulance up and down.
We continue the discussion of the Robot Design category from the FIRST LEGO League Competition. This time we stop on the programming - how to evaluate the programming of the team during its preparation for the competition.
In the final video we explore how to trigger the release of the attachment with just a rubber band. The release is triggered with a gear wheel that rotates in a specific way. This saves speed, does not require additional LEGO Mindstorms motor and is precise enough for a competition.
One of the most interesting challenges in the series of FLL Competitions. Move a block and add additional floor on top of the block without damaging the construction. In this tutorial we would focus only this mission and we would achieve two movements with only one motor which makes the attachment quite powerful.
Previously we caught the Truck with two rubber bands. The next step was to lift it. For lifting we used the Medium LEGO Mindstorms EV3 motors. In this video we are extending the attachment so that we could catch also the Ambulance. In forth video we would explore how to release both vehicles after transporting them.
In this second part we continue with the next few tasks from the FIRST LEGO League (FLL) 2013 competition. Using the same rubber band attachment we lift the house and collect a few of the humans and cargoes.
