       | Drip irrigation for watering and fertilizing comes to mind, which
       | really is a better solution and prevents the need to water
       | directly onto the leaves of the plant, which is a huge no-no to a
       | lot of plants.

       | Anyone who has done it knows if you have irrigation sorted there
       | is very little needed for seedlings to grow to full size. Even
       | with no irrigation we're only talking 5mins watering on dry days.

       | Adding all this electronics and metal to an otherwise organic and

         | I thought the same. Why not just sort out an automated

           | 
           | It boils down to something like:
           | 
           | 1. Can you sense and classify (i.e. Deep learning based
           | vision)
           | 
           | 2. After that, can you turn a pixel into field coordinates.
           | (Pose-> gps/encoder/imu/etc)
           | 
           | 3. Can you act accurately/quick/effectively enough
           | (kill/treat mechanism, electromechnical design)
           | 
           | Then it's can you do it reliably enough. Then it's can you do
           | it fast enough. Then its can you do it cost effectively
           | enough.
           | 
           | Farmers won't mess with anything not reliable. They generally
           | aren't interested in anything with worse performance than
           | existing processes, even if greener/cheaper (unless they are

             | experimentation to see what really works best.
             | 
             | But I say all this because I think a lot of companies are
             | going to be focused on meeting market demand for existing
             | farming needs. I'm hoping that for our non profit work we
             | are pushing the envelope for highly ecological development,
             | supported by enthusiastic believers in our mission. I've

             | is that long term, we can help build a system that allows
             | these techniques to scale.
             |

             | greater in this scenario. There's going to be a lot of
             | variety in what our system needs to identify and do!
             | Luckily vision is the thing I really enjoy learning. I
             | think if I can drive prototyping and I can get a broader
             | community going, we have a good shot of getting a whole
             | system going. At the very least I think our open source
