Really interesting idea. I could see this being used to remotely manage a farm from anywhere in the world. Picture a dashboard with hookups to your video feeds and statistics. When it's time to harvest take it out of the ground put it in a hopper and wait for pickup.

Not to mention the impact of testing different field configurations in varying climates all over the world. Whether the robotic design of the system is cost efficient or not, we should be at least collecting and sharing this data now.
