Robots that "eat"


We've all seen the movies, A.I., Terminator, I-Robot, where robots or cyborgs blend into society and wreak havoc. As we build smarter and smarter computers, this fantasy scenario becomes more realistic by the day. However, there has always been a limiting factor: energy source. In "The Matrix" humans blot out the sun by "burning the sky", therefore the robots can't use solar power to keep themselves running. Some robots just run on battery that end up running out after a while. In reality, our computer and robot of today are either tethered to a wall with an electrical cord, or run on a battery that runs out faster a laptop.

Recently some UK researchers have been working on developing a new sort of power source, one that we are all familiar with. They have developed a robot dubbed the Ecobot III that actually "eats" food and digests it and uses that energy converted from that to power itself. The way it works is by putting partially processed sewage into the robots digester. Bacteria within the digester breaks down the food and produces hydrogen electrons that are used in a fuel cells to create an electrical current that is then used to power the robot. Another interesting thing is that the robot can do is autonomously navigate to a nutrient rich feeding tube. Then once its done with the food, it excretes it in a similar way to how we do it (when were sick).

Currently there is a major downside to this technology. While it is working and an amazing technology with incredible potential, it is incredibly inefficient at the time. At the moment it is only able to produce 1% of usable energy for the robot. Eventually they will be able make the machine a bit more efficient and maybe allow for a robot to run exclusively on food that the robot ingests.

There is incredible potential behind this technology. This could be the new alternative energy source that houses run off of, or the new Mr. Fusion that allows us to power our time traveling De-Lorean when we don't have any lighting strikes to provide the 1.21 jigawatts to get it back to 1988. On a more sinister note, this could also allow for hyper intelligent autonomous robots to become more mobile. We have managed to create robots that learn and we have robots with incredibly realistic expressions. At this point we don't have to worry, but if all these technologies are perfected and combined, we may have a problem on our hands.

  1. Having one of those robots for your house would be like having a child if you have to feed multiple times a day. I wouldn't want to waste my time and money on buying food for a robot that could become mobile and take over the house at any moment

  2. I think this is awesome. They may be only able to make 1% of proficient energy out of sewage but thats a start. Feeding them actual food seems like a real waste when their are people in other countries starving. But if we condensed down the fuel in the sewage that the robots needed into a more solid concentrated forms then that could solve this robot food crisis.

  3. This is amazing! instead of using normal, useful, much needed food, they should use compost or discarded food instead.
    This is great news that they are exploring more innovative energy sources, perhaps soon they will be able to power other electronics with...food waste??
