Japan has always been ahead in designing machines for agriculture. I particularly like the machines that sort "edamame"
Now there is a company that plans to use drones (UAVs) for agriculture.
Any interesting machines that you have seen in Japanese plantations/rice fields?
Agriculture is a perfect application for new drone technologies - there are very few people and there is very low danger to human life if a drone gets out of control and crashes. Drone developers should be even more innovative and try crazier things :)
