Attachment part of a series of robot attachments for accomplishing the FIRST LEGO League 2013 competition. This specific construction lifts the two vehicles. It uses rubber bands for locking the levers. Take a look at the video tutorials for details explanation on how it works.
Build from LEGO Mindstorms EV3 parts.
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.

The instructions for building the improved EV3 Competition Robot by Mic Lowne
Building instructions for the LEGO Mindstorms attachment using Rubber Bands
Probably the simples trick for pinless attachments that we've found. It is a construction build in just three steps. Simple as that. But it has a lot of potential to teach you how to use pinless attachments. Pinless attachments are very useful during FIRST LEGO League and World Robot Olympiad competitions.

Building instructions for the Rubber Band Attachment
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.
- note that I have added two angled beams and an axle to illustrate how you could use the slide as an active attachmen;
Advanced LEGO MINDSTORMS EV3 Construction. It has two rear motors and it could rotate the whole from part. It has 4 wheels and is kind of like unique in the Mindstorms world.
Building instructions are not very easy and you need LEGO Education Core and Extension Sets - 45544 and 45560.
Apart from being advanced, it is also quite fun to try to build.
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.
- you should attach it to the motor, depending on the orientation of the motor
- you should attach it to the motor, depending on the orientation of the motor.
- note that you could attach it to the brick both sides, depending on which technique you would like to test. Use the video as a reference.
