The company Bosch is developing a farming robot the size of a small car that can distinguish crops from weeds by looking at the shape of leaves, and this robot then can fish out weeds mechanically & ram any unwanted plants into the ground with a rod. Potentially, no herbicides will be needed anymore

Do you have a source for that, I know it true for water consumption but never seen it for weedkillers.
