• Flywheel

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.

User this flywheels construction for experiments in physics. Start rotating the wheel and they would accumulate energy. You can try to calculate this energy and to measure how fast it would be consumed.

The construction is built with LEGO Mindstorms EV3
