My daughters and I built a 16-legged walking creature. We machined custom aluminum linkages. This robot uses an Arduino Nano. See the details, photos, and a video here:Aluminalis | Beatty Robotics

You need to get a bunch of these and attach them to the legs. You could plant perfect rows of lettuce, flowers (etc.) so quickly you'd make any gardener jealous. 
That looks really cool!
