Building instructions for the Pinless Rubber Band Attachment:

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 Ambulance Robot Attachment for the FIRST LEGO League 2013 Nature's Fury robotics competition.    The attachment grabs the ambulance car and slightly lifts it. The rubber bands help with triggering the attachment at the right time

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.

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.

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. 

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.  

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. 

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

Building instructions for the LEGO Mindstorms attachment using Rubber Bands

The first of a series of attachments that we add to a World Robotics Olympiad LEGO Mindstorms Robot. The attachment is an example for collecting ping-balls. The robot and the attachment are in the same construction. The attachment is a base for a container that could be extended.

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.
