Mindstorm is a type of LEGO® product that you can build into a robot. I decided to make one of my own with a program called LEGO Digital Designer. It costs about $5 for Mac or PC. I'm 9 and I LOVE legos and am very good with them. Anyway, I used the LEGO program to design this mindstorm bot that's very simple with weapons. I will use the building guide link to show you how its done. Below are pictures of the completed thing.
