Thread: The Robotis TurtleBot3

  1. #111

    Re: The Robotis TurtleBot3

    I am having fun with it. Lately been doing more with the underlying board (OpenCR). I will get back to doing main turtle stuff soon.

    You can obviously do it either way. It is sort of nice having a setup that has other users and a set of developers who are able to answer questions.

    Just a thought but, getting ROS and a turtlebot up and running with a book that covers you're platform, and written very well, is a
    amazing deal. It's the documentation that I like to read over and over until I get it.

    And thought I would mention, they also have created a new online ROS course for beginners:

    https://community.robotsource.org/t/...-handbook/1454
    And also mentioned up at:
    https://discourse.ros.org/t/new-ros-...-beginner/5320

    I will probably soon start playing through this course... Just finished updating their boards SPI and Wire libraries.... Now need to reassemble Turtle... But first work on water system

    Ah that's great. I think i'm going to get my hexapod until its "final" configuration, then check this out. Thanks

    Looks like ROBOTIS has a new disk image for the TB3 out and, a firmware update to (v1.2.1)

    Re: The Robotis TurtleBot3

    Thought I would mention, that ROBOTIS has been busy with the TB3.

    Right now I am going to try using an RPI3+ as I fried the UP board I had on it... Something about supplying 12v to the Expansion connector pins, it did not like I plugged the power pins into wrong connector on OpenCR3 board... I have another UP board I will probably use again soon.

    But thought I might take this opportunity to try moving over to ROS2, as this appears to be the direction that Robotis is taking, plus the underlying ROS2 communications is setup to use standardized and more secure communications, which will be supported on Linux as well as Windows and MAC.

    There is more information talking about running the Turtlebot3 using ROS2 up at:
    https://discourse.ros.org/t/tb3-intr...tutorials/5959

    And the Turtlebot3 E-Manual has a section on it: http://emanual.robotis.com/docs/en/p...ications/#ros2


    Assuming I actually get comfortable with ROS2, maybe over time it would be fun to make a version of ROS Hexapod code base that uses ROS2, plus uses the OpenCR to control a lot of the functionality, in much the way that it does for the Turtlebot3...
    As I mentioned on the thread: http://forums.trossenrobotics.com/sh...4287#post94287 I have my MK3 PhantomX working with an OpenCR board.
