Building Instructions

Third version and a third way to build a third wheel for a LEGO Mindstorms EV3. The instructions are easy to follow and in the end you will be able to attach this wheel to your robot by yourselves.

Building a third wheel for a LEGO Mindstorms EV3 Robot is always an interesting and challenging task. These building instructions are for a third back wheel. You can even notice that there is no wheel involved. It is just LEGO parts but it is one of the most stable ways to build a third wheel. There is some friction, of course, but not that much.

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 attachment accomplishes the Into Orbit Extraction mission from the FIRST LEGO League Into Orbit 2017-2018 competitions. The based of the robot is the SUV Competition Box Robot from LEGO Mindstorms EV3.

This attachment accomplishes the Into Orbit Space Walk Emergency mission from the FIRST LEGO League Into Orbit 2017-2018 competitions. The base robot is the SUV Competition Box Robot from LEGO Mindstorms EV3.

Soon we would publish and a video of how the attachment works. 

A chassis built with LEGO Mindstorms EV3 parts designed for World Robotics Olympiad

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 robot used in WRO 2014. It is a small robot with two light sensors and could be used for collecting elements. 

The robot is built from LEGO Mindstorms EV3 parts.

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
