Recently I built one of the robots on the Website with building instructions which I did not design. I built the Support Gunner, designed by Micah, also known as CATpit contractor on this blog.
It is a very unique design, and the mechanisms work very well. Good job Micah!
I am finally beginning to understand how it works, and how good the results can be. So if you have not tried any LEGO CAD software yet, you might want to give it a try, the installation is very simple.
For more information about the robot itself, go here.
If you prefer to download the instructions to your PC directly, download this archived folder.
