• LEGO MINDSTORMS EV3

Given the large number of gear wheels and axles in each EV3 and NXT sets there are many possibilities for building gear mechanisms. We are developing something like a gear box that has different axles that could all turn in different directions.

We are describing the Warm gear in this video. This worm gear does most of the magic of controlling how the different gear wheels move on the different axles. 

In this third video we show some of the tricks in building this Multi-axles mechanism. Things you could learn from an use in your next constructions.
