Here is an example of Four(4) active LEGO Mindstorms attachments built-in the frame. Two by two they work asynchronously since all of them are connected to the two separate middle motors of the SUV robot via the frame.

The left attachments work synchronously, and the right attachments are also synchronized couple.

These specific attachments are meant to do nothing in particular, but to serve as an example. Their purpose is to demonstrate different ways in which one could add an attachments to the frame. Experiment. Think and invent better frame with real world attachments that could actually do efficient work and accomplish a mission. Take a video then and share it with us. 

This robot attachment shows you how to limit the rotation of a lever. It uses two gear wheels to transfer the motion on 90 degrees. 

It could be built with LEGO Mindstorms EV3 and NXT versions. Most of the time during competitions like FIRST LEGO League and World Robotics Olympiad you need a lever for just a limited motion

Building instructions for a LEGO Mindstorms EV3 active attachment for changing gears orientations. This is the third attachment from the series.

For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.

Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.

This construction demonstrates one way of using а rack with a gear wheel. It allows to turn circular motion in to a liniar one.

Calix, from latin, means cup. Calix is made to carry an object while following a black line. Most people, when they think of robotics, they think of how the robots may help them at home, with the chores that no one wants to do. This robot is a simple version of this. You can give it a cup in the kitchen and then it will deliver it to the end of the black line! The robot uses two SPIKE Prime medium motors to move and a color sensor to follow a line. At the front it has Large motor with a gear system that lowers and rises the "cup".

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.
