Automating agriculture is a complex proposition given the number and variety of tasks involved, but a number of robotics and autonomy companies are giving it their best shot. FarmWise seems to have impressed someone — it just raised $14.5 million to continue development of its autonomous weeding vehicle. Currently in the prototype stage, these vehicles look like giant lumbering personnel carriers or the like, but are in fact precision instruments which scan the ground for invasive weeds among the crop and carefully pluck them out. “Each day, one FarmWise robot can weed crops to feed a medium-sized city of approximately 400,000 inhabitants,” said FarmWise CEO Sebastien Boyer in a press release announcing the latest funding round.
