After building the first prototype of the BattleBot (see below), I quickly realized that I needed to "beef up" the frame if my bot would face any opponent in the BattleBot ring. I added BlueTooth capability to drive the bot wirelessly, and added servo motors with aluminum arms.
Chassis Prototype
I created a chassis for a simple remote controlled vehicle, keeping the amount of PLA filament to a minimum. I utilized SketchUp for the 3D model to export the .STL file, and used a MakerBot 3D printer for the prototype.
