ROS + Raspberry Pi is such a powerful combination to create smart robots, with a somehow low cost, and very small electronic board embedded in the robot. Well, if you check how much RAM a given program consumes, with command line tools like top or htop (sudo apt install htop), you will be surprised at how much RAM nodes and launch files take. In this case, you might want to look at alternative embedded board, such as Intel NUC boards. So, if youre thinking about using 5 launch files to launch 30 different nodes, youll need 40 + 5*20 + 30*20 = 740MB of RAM minimum, just for the nodes and launch files. Note: If you need more RAM, you can also disable some programs that are launched on boot, which you dont necessarily need (auto apt daily updates, Bluetooth if you dont use it, etc). It's convenientif the ROS2 environment variables are Although there are many advantages, there are also some limitations that you need to be aware of, and some good practices that you should follow. There is a simple way to do that: you can use the multi-machine functionality from ROS. GSOAPHOME - set to the location of the gSOAP toolkit. So, if you just run catkin_make, youll see something like that: As there are 4 available cores on the Pi, the command make (which is launched by catkin_make) will have the -j4 -l4 argument, so as to use all 4 cores.
