These robots provide a high-tech solution to an age-old farming problem: how to get rid of weeds...

The most compelling part is that the cost is much the same as chemicals but there is less damage to crops

It is good that they are moving away from herbicides, but that is a loss of jobs for humans. What are people going to do to make a living when everything is done by robots?

one would need a lot of them to get the job done unless they can do 120ft at 8 mph and not run down the standing crop. not much to any damage with wheels and 120ft booms on a crop under 5 in.
