UPDATE: I’m leaving this series up for historical purposes, but please note that I no longer recommend Ubuntu Core or snaps for use in robotics. This is the fifth (and final) blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post we discussed methods of control, did a little math, and wrote the ROS driver for our robot. But it still required several nodes to be running at once, and sharing it with the world involved uploading your source code somewhere and convincing people to install ROS, build your package, and use it....

UPDATE: I’m leaving this series up for historical purposes, but please note that I no longer recommend Ubuntu Core or snaps for use in robotics. This is the fourth blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post we worked on getting data out of the wireless controller and into ROS in a format meant for controlling differential drive robots like ours: the Twist message....

UPDATE: I’m leaving this series up for historical purposes, but please note that I no longer recommend Ubuntu Core or snaps for use in robotics. This is the third blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post you were introduced to the Robot Operating System (ROS), and got your robot moving by ROSifying one of the CamJam worksheets. Today we’re going to move beyond the CamJam worksheets, and work toward having our robot remotely controlled by focusing on our wireless controller: getting data out of it and into ROS messages....

UPDATE: I’m leaving this series up for historical purposes, but please note that I no longer recommend Ubuntu Core or snaps for use in robotics. This is the second blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post we walked through all the hardware necessary to follow this series, and introduced Ubuntu Core, the operating system for IoT devices. We installed it on our Raspberry Pi, and used it to go through the CamJam worksheets....

UPDATE: I’m leaving this series up for historical purposes, but please note that I no longer recommend Ubuntu Core or snaps for use in robotics. Some time ago I created a blog/video series that walked the reader through creating a prototype using the Robot Operating System (ROS) and taking it to production using Ubuntu Core. However, that series was intended more for robotics professionals; it assumed quite a bit of ROS knowledge, and required some costly equipment (the robot was about $1k)....
