It all started with a can of Pepperidge Farm Crème Filled Pirouette Rolled Wafers. It ended with this bot. The build took quite a few weekends and lots of overnight prints, days even. I don't know how much yardage I wasted on failed 3D prints. The end result is an Android controlled, Bluetooth signaled, 3-wheeled, 3D printed cylinder shaped Arduino bot that flip-flops when quickly reversing directions.
I love that with a few electronics and a 3D printer, tons a fun stuff can be built.
