If you live in a family of average size, you know the bathroom can get pretty crowded. Now you may soon have to make room for your robot, too.
 
Scientists working out of the Bristol Robotics Laboratory have invented a robot that powers itself by collecting its own food and water, digests it, then poops out the waste, according to Scientific American. It may sound unconventional, but scientists hope that a new generation of these "ecobots" will not only be self-sustaining, but may even help recycle and reuse food waste.

"Robots that eat biological fuels could find enough fuel almost anywhere," said John Greenman, a microbiologist at the Bristol Robotics Laboratory. "There is organic matter anywhere on Earth — leaves and soil in the forest, or even human waste such as urine and feces."
