John Deere Robotic Lawnmower is Quiet & Durable

While I’m wishing it was a more like a Roomba instead — my apartment is so dirty! — this robotic John Deere lawnmower is pretty darn clever. And sorta cute.

The John Deere Tango E5 not only operates in all weather, it also doesn’t make that loud, annoying “lawnmower sound” or require any emptying of grass clippings. It also returns to its charger when its battery gets low…which is both cool and creepy.

    • Funny, that was my takeaway from this video as well. It will randomly stripe the yard til the battery is low and then return to its dock. I was waiting for them to show how it plots where it hasn't been yet and targets those areas.

  1. I'll be impressed when someone makes a robot mower that learns what the yard is shaped like, then develops the most efficient way to mow it. The zigzag crossing pattern is just too inefficient.

  2. This is like a cheapo old time screen saver… I remember doing this like this 15 years ago:
    while(x)
    {
    x=x+i;
    if(x>=640||x<=0) i=i*-1;

    You would think with GPS and some AI in 2012 someone could come up with something better… probably there are patents on the better stuff and we need to wait 20 years.

  3. Wow, yea, totally inadequate. Basically, you can only guarantee that the mower has mowed in front of the charger.

    So, for those of you not up on robotics, here's the challenge. A GPS isn't going to give you accuracy below about ten meters, thirty feet. That's fine if you're on a six meter wide lane of a highway, doesn't work so well if you're trying to make twelve inch wide rows in the grass. When driving on grass, wheels provide way too much skid for the robot to figure out where it is based on how much the wheels turn. Vaccuum cleaners have it much easier because they can tell (roughly) where they are based on their wheels turning.

    The other option is that you set up objects in your yard that the robot can "see" (visually or via radio waves) so it can recon off of those. This might work, but I'm not sure you could get six-inch resolution off of that, especially on a bumpy surface, and you have to worry about things that block line of sight completely messing you up. At this point, however, you're talking about establishing multiple tiny radio transmission towers on your property, and that may be more than most people are willing to spend for lawn mowing. You can pay people to do it much more cheaply.

    • 1 cm accuracy with DGPS or PLGR; but I guess this is a matter of national security and that type of receiver is probably much more expensive than the lawn mower, hehe.
