Thread: The Robotis TurtleBot3

    Re: The Robotis TurtleBot3

    What's your experience with the Nano? Have you compared it to other boards?
    I kind of don't see what Nvidia wants with the Jetson Nano. It's the quad core ARM from the Jetson TX1 with half of the GPU of the TX1. It's an old GPU architecture (Maxwell) and as such not particularly energy efficient for what it does.
    It's three times the price of the Raspberry Pi 3, so it has no way to compete for "cheap linux." It's a quarter or less of the throughput of the TX2, although it does have a smaller form factor.
    Is it actually "the sweet spot"?

    The fan was overkill as I have never been able to get it hot enough to turn on
    Once booted onto the USB this is a full on speed demon with V2 camera and as far as I can tell a raspberry PI GPIO or
    something unbelievably close to it. Still playing but I have the full melodic desktop working and am pretty happy so far.
    Check out jetsonhacks he is working hard on the board as well.
    "The Nano is roughly twice the cost (you don't need a case to keep it from throttling), roughly twice the performance,
    4x the RAM, and uses the same power as a Pi 3B+. That's a win, in my book!"

    And a built-in real-time clock chip, so you don't get the wrong time on boot like with the Pi ...
    Worth the price just for that :-)

    LOL and unfortunately there is no RTC (Real Time Clock) on this model.

    Because saving 25 cents was totally worth the hassle of invalid file system timestamps ...

    Every hat/attachment to any Pi connector should contain an RTC ...

    Re: The Robotis TurtleBot3

    I am now cheering for the PI4. I have the Raspbian Desktop Image up and running but No ROS image and I could not get that ROSberryPI to run so I am still looking.

    Sounds Good - I just received a 2gb board, have an SD Card, and wall wart power... But don't have right HDMI cable... Should arrive later today or so.

    Trying to decide to try Raspian or Ubuntu.

    Re: The Robotis TurtleBot3

    Also wonder if any of you have tried to run your RPI 3 or 4 using SSD Drives instead of SD Cards?
    Like for example what is described in:

    Looks like it might be interesting to try...

    Re: The Robotis TurtleBot3

    Yea, once Ubuntu officially supports Buster things will really take off.
    I am not sure when that is.

    Re: The Robotis TurtleBot3

    It looks like Ubiquuity has a image for the rpi4.
    Note (I should note that this is Loaded with ROS Kinect 16.04.)
