Lukas the robot toils weeding in the fields
Why send a human to do a robot's job? Lukas the mobile agricultural robot can take care of weeding those fields for ya. It makes use of onboard infrared cameras and image processing software to distinguish between the good stuff and the evil weeds, and is able to yank out the latter for most crops grown in rows. The PhD project of Björn Åstrand at Halstad University in Sweden, Lukas isn't exactly ready to enter the market just yet, but should be ready to be farmer's new best friend in a few years. Whenever Lukas is finally ready for prime time, we'll be able to rest assured that the planet is safe in good hands, and guiltlessly plug ourselves into the Matrix.
