Building Instructions

This LEGO Mindstorms Attachment has three gears, one frame and two axles. The goal of the attachment is to use the gears to change the direction in which the motion is transferred.  

Building instructions for a LEGO Mindstorms EV3 active attachment for changing gears orientations. This is the third attachment from the series.

This LEGO attachment connects a LEGO Mindstorms EV3 Motor with a LEGO Technic Linear Actuator. The connection is through a couple of gears which makes the whole instructions quite interesting and useful as an example. 

The attachment was used during FIRST LEGO League 2014 Robotics competition.

A similar LEGO attachment the previous once, but this one is with a different gear ratio. Again using a frame, two axles and two gears you can change the direction of the motion.  

One LEGO gear is powering two LEGO Gears and at the end, from one motor we rotate two axles in opposite directions. Follow the building instructions.

These are building instructions for a LEGO Mindstorms EV3 demonstration model. In the tutorial, we are using it to demonstrate the working and relations of LEGO Gears.

This is a Camel-like robot. We demonstrate an interesting use of gears to make the Camel walk. Fun and entertaining way to learn how to transform motion.

This is version 2 of the LEGO Mindstorms Grabber. It makes use of 4 gears to make both levers active.

Building instructions for a robot for the World Robotics Olympiad Sputnik competition. This is the light version without the lift at the top.

This is the third version of the LEGO Mindstorms Grabber. This time we use a LEGO EV3 Medium motor and worm gear to make the two levers move smoothly and symmetrically.

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. 

When placing the rubber bands check out the tutorials

Placing the white rubber band is shown at https://www.fllcasts.com/tutorials/105-rubber-band-attachment-with-a-flywheel-solving-fll-2014-search-engine-part-2 at around 05:40.

If you take a look at the videos for this attachment you will see a nice idea on taking the track and the ambulance. These two vehicles from the FIRST LEGO League 2013 competition had to be collected and returned back to base.
