HortiBot won't go down as the first robot with weed extermination as its sole mission in life, but this particular robot ups the ante in a serious way. Conjured up by a team of Danish agricultural scientists, the three-foot by three-foot autonomous machine is "equipped with a computer and GPS to find the exact location of weeds," and being that it's also reportedly self-propelled, you hardly have to keep an eye on it. Moreover, the device can be flanked by an array of weed-removing attachments depending on a farmer's specific needs, and promises to curb "herbicide usage by 75-percent." Currently, the cost of one Hortibot would run around $71,000, but the crew hopes to land a manufacturing partner and reduce those charges when it (hopefully) goes commercial.
