Robots are gonna rule the world one day. If they're not cooking for us, then they're out chopping weeds in a field somewhere. A group of engineers at the University of Illinois at Urbana-Champaign recently developed a solar-powered, weed-chopping robot. The high-tech killer, which uses GPS for navigation, stands a little over 2-feet tall and 5-feet wide. Once it spots a weed, it'll chop it off, spritz the remainders with some weed-killing juice, and move on to the next target. The robot's got two small cameras and uses an onboard Windows computer complete with an 80GB drive and a wireless Internet connection. Sadly, it sounds more powerful than our current laptop.
