Rather than pick another of the community supplied robots that come with the EV3 software, I wanted to build a Rubik's Cube solving robot. It just so happens there is a fantastic project already available that creates one from just the 31313 EV3 parts - the MindCub3r created by David Gilday. Awesome :)
This is the second part of an unknown number of reviews of the LEGO 31313 Mindstorms EV3 robotics set. If you haven't seen the first part, I recommend reading that to understand what this set is all about.
Disclaimer: I have a background in Microelectronics Engineering which basically means I love robots. Combine that with my career in IT and love of LEGO and you end up with a 100% biased review of this Mindstorms robotics LEGO set :) Plus it's kind of long!
