The AI robot for weeding was shelved for slowness of the optical computer processing which I wrote in C language starting at 2015. I was spraying with an ink jet printer, 60 feet of weeds in a lawn, 12 inches wide path, per hour. The recent breakthrough in AI and improved computer speeds, since I completed this in 2017, might make this project practical per the breakthrough at UofT Geoffrey Hinton and his team: https://www.cs.toronto.edu/~hinton/ Apparently is was in 2012 when they did feedback to improve the AI algorithm. I did not know about that idea in 2015. https://www.utoronto.ca/news/geoffrey-hinton-fields-questions-scholars-students-during-academic-talk-responsible-ai
The video shows successful proof of concept.
