CC sounds pasionate for who have development knowledge, not my case, It’s sounds crazy try to modificate ballon finder code to recognize weeds and, for ex. spray them ?
How would you recognise weeds over other plants? You might quickly get some very upset neighbours
I’m thinking not over other plants (yet), I think over no till soil, sometimes we have weeds only like small groups, I imagine the multicopter finding that groups over dry straw and spraying them, finding something green over brown background; farmers can save money time and more friendly with natural environment. Perhaps only a crazy idea
