Robotic Farmer: Prospero, a single member of a robotic swarm
The video I think was very impressive. This little robot is able to sowing for you to do. It can even scan if he has in place already planted a seed. If you have a really big box, you can use several of them in the swarm. that is, they work together.
On the youtube page to the video is a few more explanations, eg. that they have also developed robots for the care of crops and harvesting. The next generation should be able to pick and weed and all these beautiful features in a Robots offer. I would find quite such a robot left to see run in neighbor's garden:)
