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.

The AI Weeding robot was slow although the concept is proved. Next, I worked on a narrower
application with much simpler components, a weed wand which only drops vinegar, an
environmentally inert poison which will wilt dandelion flowers. Here is a video of the completed device,
which uses a $5 microprocessor instead of a full computer and it has fibre optic cables to inexpensive
light sensors and a marriot bottle concept as a valve with no seals:

This can be constructed with less than $45us of components whereas the robot was $700us of parts.
