Aerospace Engineer Makes Robotic Lawnmower with 46 3D Printed Parts

German aerospace engineer Andreas Haeuser has been devoting his knowledge and talent to designing ingenious inventions that can be easily and inexpensively built by anyone with a 3D printer. His latest, the Ardumower, is an automated robotic lawnmower - sort of like a Roomba for the lawn - consisting of little more than an Arduino board, a rechargeable battery, and 46 3D printed parts. He also offers a comprehensive, step-by-step instruction manual along with the STL files. Read more at 3DPrint.com: http://3dprint.com/120980/3d-printed-lawnmower/
