Beetleweight Battlebot
Over about two months I did most of the CAD for a 3 lb battlebot, drivetrain and weapon included. We sketched the concept in Onshape, brought it into SolidWorks, and ran through three iterations of the drive base and weapon before committing to a design. It worked, but the motors and electronics fought for space and the motor mount was too fragile to trust. I learned more from it than from most of the builds that held together.
