Competition Demo - housekeeping

Announcements

Hello, a bunch of final updates before the Competition Demo:

  • Zoom meeting: Launch Meeting - Zoom code 16216
  • standard notice that VMs will be unavailable between 9-11AM and 19-21(PM) CEST on the day of the Test
  • we’ve added a fifth camera, named “main” - in case some of you decide to drive manually - it’s much easier to do so if you’re able to see the robot itself in the image. It can be used to detect items too if you want but it may not be useful in that matter due to the steep angles
  • camera angles have slightly changed - the ones on the left and right are looking slightly down and front and back are looking slightly up. This should help with the detectability of, respectively, items and markers. We will be tuning that if needed, so feedback is welcome
  • there’s an additional topic with compressed lidar stream available - you’ll find the decompressor setup in compose.lidar-decompressor.yaml(.reference). In order to use it you may need to build Dockerfile.lidar-decompressor yourself
  • although this have not been announced in the technical handbook - some of you have included GPS data in your pipelines (as per your presentations last time) - we’re working on making it available - but it may or may not happen tomorrow
  • some of you seem to have missed it https://github.com/husarion/erc2025/tree/main/ansible/roles/teams/files/ros2router contains new versions of the ros2router setup - in addition to the changes in the image itself more than a week ago. If you’re still struggling with ros2router please have a look at the updated Ros2router short tutorial - #12 by pidpawel
  • you may need to regenerate ros2router (or use the one from the repository) filters at the beginning of the test - if you want to use the additional camera or the compressed lidar. (Something like ros2 topic list | xargs ./create_filter.sh > filter_example.yaml on your VM in ros2router directory)
  • have in mind that we tried not to modify your files and saved updated files/directories as .reference. Please do the overwriting at your own if you need to do so
  • please have in mind that you can do such initial setup tasks while we’re going through the checklist before your Time Slot starts - this may only be a couple of minutes but plenty of you’re asking for those minutes. Your VM is attached to the robot usually while we start talking so please watch the up/down status on your VM network interfaces in the meantime
  • again - screen share only - it’s much easier to help you troubleshoot issues if you do so

Good luck!
