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.
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.
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.
We've separated the BigDaddy robot into a few smaller modules. This teaches modularity and gives you the option to reuse some of the modules and to look at specific modules.

Building instructions for the catapult that could be placed over the LEGO Mindstorms EV3 Brick. The idea of the catapult it to throw objects. The fact that it is over the brick makes it very convenient to place the motors below the brick and to use the Catapult.
This robot construction itself was used in the FIRST LEGO League Senior Solutions competition
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.
Built from LEGO Mindstorms EV3 parts.
Building instructions for the LEGO Mindstorms robot attachment used at the FIRST LEGO League Natures Fury Competition. This robot attachment takes two of the building and moves them without demolishing them. It is a good example of the use of gear wheels and worm gear. The gear wheels move levers in opposite directions.
Building instructions for this LEGO Mindstorms EV3 attachment for the FIRST LEGO League Nature's Fury 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.
This construction uses a differential. Both wheels could turn with different speed and this makes a construction much more stable when turning.
