Robot with pincers can detect and remove weeds without harming crops

Artificial intelligence is getting down in the weeds. An AI-powered robot that can distinguish weeds from crops and remove them could eventually be used as an alternative to chemical insecticides. Kevin Patel and Nihar Chaniyara at tech start-up AutoRoboCulture in Gandhinagar, India, have created a prototype of the device, called Nindamani, specifically for cauliflower crops. The robot is powered by a pre-existing image-recognition algorithm.
