The Future IRL: Robot farmers do the dirty work

The US is facing an agricultural worker shortage, along with aging farm owners, at the same time it juggles demand in food from a global population boom. If we're being blunt, those elements added together would mean farmers and production are straight screwed. Luckily, some engineers and researchers are creating robots that are already beginning to ease the load. Blue River Technology in Sunnyvale, California is testing "See and Spray"-- machine learning and AI software inside a robotic tractor attachment that aims to change the chemical game. The program can recognize the difference between crops and weeds, then sprays herbicide only on the unwanted plant.
