Idea: make this into a weeding machine

[jneb]

While weeding my garden, I was thinking that opendog (or a lightweight version) could be a great weeding robot!
It would work likes this:
Walk through the garden, find a small plant, make a few pictures, look it up at plant.net, and if it matches a user specified list, pull it out.
Wheels are no option for such a robot, so opendog would be great for this (but a bit heavy). Your projects contain all the elements to make this work
If it was a product, I would buy one!
