The Element drives itself continuously at around two miles per hour over farmland, using an advanced computer vision system to identify crops and unwanted botanical invaders. With two-axis robotic arms positioned close the ground, it can flick weeds out of the way where they’ll dry out before they can grow seeds and spread.
Maybe that works in California. In rainier parts of the world that’s an awesome way to spread weeds all over the place!
It kills weeds by uprooting them, before they have a chance to produce seeds.
So it just needs a bag attached for the weeds, then.
