DIY Attack Roomba

Have you ever wanted to inconvenience yourself by building the most useless and pitiful robot ever? Well, have I the design for you! This homemade DIY attack Roomba comes complete with 1 front-facing ultrasonic sensor... and nothing else! Add a little spice and your flavor to your boring old graduation party by gluing your pocket knife to the front of this so that when your ol' robotics pal sees a 3d printed motorized knife coming at him with stolen robotics parts, he won't even know what to think!

on the off chance that someone has these parts or parts similar to these, I will post this here, just as proof that maybe this whole engineer thing wasn't for nothing.

also included is the step assembly, compressed as a rar file
