Robots are currently being developed to take over one of the most labor intensive jobs out there: farming.Scientists in Israel and Europe are developing just such machines, which could identify, spray, and harvest crops. This selective spraying could potentially reduce the use of pesticides by 80 percent.AdChoices广告“The technology is ready, and now we can start seeing this penetrating into the market,” researcher Yael Edan told Discovery News. “I would say there will definitely be robots out there in five years — maybe not be on every farm, and maybe not for every farmer. I think now the time is there.”The biggest hurdle is developing computers and robots that can identify vegetables and fruits accurately. So far researchers have been able to achieve this with about 80 percent accuracy, but that’s still far less than with an actual person.
