The TurtleBot3 robot is a standard platform robot in the ROS community, and it’s a reference that Canonical knows well, since we’ve used it in our tutorials. As a matter of fact, we use it to demonstrate some of our work, such as distributing a ROS stack through snaps. This robot embeds two boards, a ...

What unifies this impressive portfolio is the fact that all of these snaps are made for the x86 platform. Not anymore. Now, don’t panic! The x86 snaps are not going anywhere. But ARM-supported KDE snaps are ...
