    Re: The Robotis TurtleBot3

    Crap. Forgot that the Kobuki was a bit like the Create in that it dropped all the vacuum hardware for extra payload, battery, and dc-dc power supplies. As for the payload ratings of the Turtlebot3, I expect those are heavily inflated and based entirely on the stall torque of the XM servos and/or 'crush' strength. The sturdier plates should permit a relatively high payload compared to Trossen's small lasercut rovers, but I seriously doubt they can actually move much with even half their rated payloads.

    Here is a great example of all of the different versions of the turtlebot3 that have been made. Most of the design files are on the OnShape website now.

    So the waffle apparently can carry quite a bit of weight, but it slows it down significantly and negatively affects odometry because of wheel slippage and/or drag from the tiny casters.

    Cool stuff,

    Wondering about the one shape designs? Can you download them to do 3d prints and/or can you have them printed?
    For example I wonder how long it would take to print the Tank parts on my 3D printer...

    If I went that way maybe should get another printer :lol: Although I have a friend over in the Teensy land who is trying to entice me with a kickstarter for a 3d printer: https://www.kickstarter.com/projects...project_update

    For big/complex things, I find it better to have ShapeWays do it. I print anything up to 5" on my Printrbot Simple Metal in PLA, and it works fine for that!

    Oh, how I want a MarkForged printer, but that BuildOne Deluxe is something I can actually afford right now. Hopefully it will go as well as the Teensy-3.5/3.6 kickstarter and not the RePhone 3G/4G. A year and a half of waiting to learn it was finally nixed a few months ago with no public announcements of that fact; at least I should get a proper refund in the next couple weeks.

    By the way, I hear this one actually prints better than the price would indicate:

    Assuming you don't need giant print areas (which then end up taking days to actually print to!)

    I backed the kickstarter for the original version of this printer and it was a great little printer for the price! This is a upgraded version at only 299.99.

    It is also really easy to create .STL files using OnShape. Click on the link for my tutorial.
