Ok things are starting to move along here and the prototype test rig is now just about finished. I am now about to start the programming side of things. Its winter here so I am thinking I can set up a test course inside one of the farm sheds as the fields have sheep on them now and no weeds. I have a space with a nice concrete floor I can scatter some bright objects on the floor like some yellow rubber ducks or painted blocks of wood and build a classifier to detect them against the concrete floor. I’m hoping that the bright colour contrast will mean the ducks will be accurately and easily detected.
Im new to coding so my first challenge is sending data to the Arduino from Python in the form of an array to switch off and on the spray heads. If anyone wants to help please do I will post what I have on a Github account.
