The Best Inventions Of 2007
From the phone that has changed phones forever, to futuristic cars, to a building made of water, to a remote-controlled dragonfly — a dazzling display of ingenuity
The HortiBot, designed by Rasmus Jorgensen and a team of Danish scientists at Aarhus University's Institute of Agricultural Engineering, spares farmhands the most tedious chore: weeding. As the bot winds through a field of crops — a camera keeps it on track, row by row — it identifies weeds based on the shape and orientation of their leaves. It can be rigged to spray or pull, farmer's choice.
