As you so in the previous video - Rubber band attachment with a flywheel - solving FLL 2014 Search Engine (part 1),  the FIRST LEGO League 2014, World Class, Search Engine mission is very interesting. We are accomplishing it by slowly and precisely pushing to the mission model.

The attachment is a pinless attachment build for the EV3 competition robot.

Pinless Flywheel and Rubber band attachement for LEGO Mindstorms robots

Kiril Mitov's most favourite attachment. To quote him "I had a really great fun building this attachment and recording the videos for it".

It's an attachment with a Rubber band and a Flywheel and a Gear Wheel and a Worm Gear. So much knowledge in just one small attachment. The goal of the attachment is to be able to have an active attachment without actually having a motor. So you can place that attachment and it will do the work for you instead of using a motor to power it. 

Build with LEGO Mindstorms EV3 set.
