Solar Weed-killing robot

weed robot

This is a robot that already made the rounds last year, but we like it so we are going to repost it and that is something you are just going to have to deal with. What’s wrong with a little repetition people? You have the same pictures on your walls at home every day don’t you? Geesh…

If going out and spraying weed killer on weeds in your yard is too much of a hassle for you, why not get a friendly robot to do the dirty deed for you? Engineers at the University of Illinois have developed a solar powered robot that can search out weeds and then kill them with extreme prejudice. It utilizes GPS, robotic vision, and ultrasonic to find its way around your yard. When it finds a weed, it reaches out and slices it down with it’s cutting arm, then sprays it with herbicide to get the job done. Trucking along at 3 MPH, it’s a total killing machine. This guy isn’t for sale, but perhaps if you promise to make a generous donation to the University of Illinois they’ll let you borrow it once in a while.

    I posted about this in the forums, back before we had a blog. I said it then, and I’ll say it again:
    “The robot is too freaking BIG. Swarms of small bots that could crawl between rows of plants would get the job done, but this behemoth couldn’t get anywhere near the weeds it needs to kill. But hey, they did a lot of hard work, they mean well, and they’re headed in the right direction; so U of I gets a Special Olimpics gold metal for this one.”

    I’m not sure, this was made for a field, not a garden. I agree it’s too big for anything but a field, but I think it would do just fine keeping the weeds off a soccer field for example. Plus it’s a prototype :P Robots running around spraying poison though…. gives one pause.

    Weird. When I saw this thing I immediately thought about agricultural applications, and my brain quit right there. I’m trying to solve the world’s problems here, man! Dandelions in the outfield do not concern me.

  4. Have to agree with Dave on this one, it is far too big for proper weeding but again, like Matt says it would be great for a soccer field.

    I couldn’t understand some parts of this article Solar Weed-killing robot, but I guess I just need to check some more resources regarding this, because it sounds interesting.
