Source the 'underlay' installation workspace followed by the 'overlay'. && apt-get update && rosdep install -q -y \ There are still a number of new features to explore with Navigation2, but my immediate focus is going to shift towards getting MoveIt2 setup on the robot, since I cant easily swap between ROS1 and ROS2 anymore after upgrading the operating system. Yocto and ROS 2 allow you to build a production-grade custom operating system for robots. While I previously installed ROS2 Foxy on my Intel-based Macbook, the situation is quite changed now with MacOSX being downgraded to Tier 3 support and the new Apple M1 silicon (and Apples various other locking mechanisms) making it harder and harder to setup ROS2 directly on the Macbook. The data type can be made visible by using an RMW/DDS combination that supports type forwarding, such as rmw_connextdds (or the older / deprecated rmw_connext_cpp). May 23rd, 2021.

Please set your default shell to bash. I also frequently want to be able to interact with my robot from my Macbook. While developing with widely known Linux distros is definitely recommended in robotics, the resulting firmware when using Yocto delivers not only a smaller (size-wise) footprint, but also a more lean and unloaded execution environment where you have absolute control of what runs. If you need more specific help (because environment setup files can come from different places), you can get answers from the community. Why complicate yourself so much, Why Yocto/PetaLinux is a great fit for hardware acceleration in robotics, Step 2. ROS2 does the same, except it only output how many publisher or subscribers are on this topic. ROS2 Nodes, Topics, Services, Parameters, Launch Files, and much more.
