Building Instructions

Building instructions for a LEGO Mindstorms EV3 Multi-axles mechanism

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.

Alice is a lovely little bird, with some amazing mechanisms on her feet. It uses two large motors and one medium one as a head, which drives both its wings.

Building instruction for both EV3 and NXT. The whole catapult is build in exactly 78 steps.

Interesting and useful attachment for dropping a LEGO human at a specific location. It uses a lever and a gear wheel. When the lever is pressed the wheel rotates.

The attachment is constructed from LEGO Mindstorms EV3 sets.

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.

Robot for collecting ping pong balls used in the World Robotics Olympiad competitions. It is constructed with LEGO Mindstorms EV3

These are building instructions for one of the greatest LEGO Mindstorms attachments that we've built. Super simple and easy to follow and at the end, you have an attachment with a rubber band that controls a lever and that could lift objects from the field. It could lift them up. Also because it is with a rubber band you don't need a motor and you could use the motor for other attachments. 

This robot is a spin-off of the Useless machine built from LEGO Mindstorms EV3. This robots mission is to be the last to press the button it holds.

This WRO robot is designed to collect a lot of ping pong balls in its container. It's built with LEGO Mindstorms EV3 45544 and 45560 sets. These are the LEGO Educational sets. The robot has two chains that collect the balls and push them into the container attachment. This is one of the larges robots we've uploaded at FLLCasts yet. You could learn a lot by following the building instructions and paying attention to the details of how this robot is built. All the alignment, all the connections. Really beautiful.  

Another example for a quick pinless attachment build with LEGO Mindstorms EV3 robots.

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.
