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;

- you should attach it to the motor, depending on the orientation of the motor.

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

- 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. 

Third part of the LEGO Mindstorms BidDaddy Competition Robot. 

You can attach a frame around the front wheels to make them more stable and to allow for better aligning. The module extends the front wheel built at BigDaddy Front - front wheels mechanism module for a large LEGO Mindstorms Competition Robot

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.
