I love the Farmeron concept of automating farm management via the Internet of Things.
Huge potential for robotic (dairy) milking and automated animal health tracking.
The true essence of IoT – Monitor (DoorBot) and unlock (Lockitron) your front door from your phone/tablet from anywhere in the world.
DoorBot is currently under development with planned shipping in September 2013.
