    Cut the grass, for many a boring job. But in our place there could be a robot, E-Mow, a prototype made by a student of the George Mason University. “It pollutes!”, One would immediately think but it is not like that at all. The special lawn mower is powered by chopped grass pellets and self-produced.

    What it cuts, E-Mow, uses to feed. There is no need to keep up with him, he does everything by himself. It is in fact a computerized system. "Just tell it where you want to mow, hit enter and it goes alone", has explained its creator Jason Force. To be precise, a few grass pellets must first be pre-loaded but only at the beginning. The robot will create the pellet itself it needs to complete the job. All with the double advantage of saving time and money.

    After photovoltaic tractor, comes the pellet mower. The E-Mow is built on the body of an electric toy car but the smart vehicle is able to convert the pellets into fuel using a small gasifier biomass.

    It is a system capable of converting organic matter into gas through heat. It is also equipped with an air filter and a fuel gas mixer. The team is seeking funding to build a complete power system. The finished product will include an on-board computer, a GPS system, a water extractor, a rotary dryer in addition to the engine.

    At that point, users will simply have to download one property overview from Google Maps and overlay it on the photo of your backyard. Finally, they will have to report any obstacles that e-Mow might encounter. The internal GPS system identifies roads, sidewalks, any driveways and other visual boundaries.



    The vehicle is currently a prototype and its designers hope to raise funds to start production.
