Constructing LEGO Mindstorms EV3 Competition Robot - the Process

In Episode 58 we introduced you to a LEGO Mindstorms EV3 Modular robot. In this tutorial, we show you how we reached that construction. We start from a construction found on the Internet and take you through the process of examining and improving it, till we reach a more stable and reliable robot.

You could find building instructions for the initial version of the robot under the materials tab and also take a look at Episode 58 for building instructions of the end version of the robot.

In this tutorial we take a look at several problems of the initial constructions found on the Internet:

  • the Back Wheel - it should be firmly attached to the robot. Best case is when the weight is uniformly distributed and falls on as much surface as possible.

  • the Axles of the Front Wheels - usually, when the axle of the front wheel is attached just to the motor it is loose and bend under the weight of the robot. This is why we built an outer frame to hold the axle.

  • the light or color sensors - it is always better if they have covers, which isolates from outer light, and are closely to the ground. For more on this take a look at Episode 3.

  • the whole robot is modular - that is not necessary, but always can be useful later, when you want to modify your construction.

In the next part we will improve the robot even further. Meanwhile we will be glad to hear from you, so do not forget to comment bellow.
