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.

There are constructions, especially on our platform, that you could build partially and then experiment with different ways to complete them. This is a very good exercise for creativity. It is sometimes difficult to build a whole robot from scratch, but finishing the robot with a few wheels and attachments is doable.
