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.
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.
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.
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.
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.
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.
