I’m trying your platform and just doing the quick walkthrough. It fails building the turtle, commandcenter and simulator components with the following message:
Cloning "https://github.com/rapyuta-robotics/io_tutorials" ... error: fatal: reference is not a tree: 1e508f3546d3019109ec2ed35fe1c2a4791f7b08 Unable to checkout '1e508f3546d3019109ec2ed35fe1c2a4791f7b08' in submodule path 'rosbridge_suite'
I guess you recently changed the source of your submodule inside the tutorial git repo and it seems like there is no way to pin a specific git commit for a component to test this. So I guess I have to wait until this is fixed to continue. My educated guess is that it’s still using the old submodule url and therefore not finding the reference?!
