Category Robots Base Constructions
This is a category only with mobile robots bases that you could directly build and use for competitions, classes or learning at home.
Building instructions for a LEGO EV3 steering car. We use two large motors, so that the rear wheels will be driven independently by a separate motor. For your convinience, you can use the EV3-G MyBlock for moving the Boomer.

This is the chassis for the popular FTC Push Bot. The robot is built with the Tetrix set and uses two motors. When preparing for a FIRST Technical Challenge competition (FTC) it is very useful to have a chassis from which you could start working. It might not, and will surely not be the final robot, but a good base is always useful.
With this chassis, we've also made a short course of how to control it. Take a look at FIRST Technical Challenge. Basic GamePads, control and attachments for the Tetrix set.

It sparks. It's sparking. Well, the goal of this LEGO Mindstorms building instruction is to spark the imagination when the base of the construction is very simple. Just two motors with the brick above them and one of the most classic ways to attach them together - with angled beams.
The construction could you EV3 or NXT wheels so chose wisely. As a robot chassis base, it is suitable for all kinds of extensions. An interesting thing is the motors are attached to each other with a frame which is getting very popular in the EV3 world.

This robot extends the Tetrix Box Robot chassis for FTC competitions with an additional arm. The arm could be used for lifting and placing objects and could be quite useful.
There is a special rubber band at the end of the arm, because there are not enough parts in the Tetrix set and we had to use a rubber band. But the principle of the arm is interesting, useful and you should be familiar with it - the arm keeps the motors always in the right orientation.
