Military Researchers Develop Corpse-Eating Robots

From the file marked "Evidently, many scientists have never seen even one scary sci-fi movie": The Defense Department is funding research into battlefield robots that power themselves by eating human corpses. What could possibly go wrong?

Since they apparently don't own TVs or DVD players, researchers at Robotic Technology say the robots will collect organic matter, which "could" include human corpses, to use for fuel. But if you picked up anything on flesh-eating robots over the years you know they'll ignore that tasty soybean field and make a chow line right to the nearest dead body. And, if the machines can't find enough dead people to eat, they can always make new ones.

Oh dear oh dear we can't leave these people on their own for a while that they start having strange ideas and putting them into practice !

Ecobot Eats Dead Flies for Fuel

Robots walk, robots talk and, soon, robots will eat, too.

Researchers at the University of the West of England, Bristol, are working on creating autonomous robots that power themselves using substances found in the environment. Professors Chris Melhuish and John Greenman plan to give robots their very own guts – artificial digestive systems and the corresponding metabolisms that will allow robots to digest food.

Doing away with solar cells and batteries, their robot Ecobot II has a stomach consisting of eight microbial fuel cells, or MFCs, that contain bacteria harvested from sewage sludge. The microbes break down the food into sugars, converting biochemical energy into electricity that powers the robot. With bacteria breaking the food down and a type of robotic "respiration" in which air provides oxygen to the fuel cells to create useful energy, the whole system mimics real digestion as closely as possible.
