I hope that your preparations are going well!
Please note that the Refbox has been updated based on the rules changes. You can test the latest version from the Github source ( https://github.com/industrial-robotics/atwork_central_factory_hub)
The heights for 5cm, 10cm, and 15cm stations will be a little different in Sydney as the organizers were unable to provide the exact heights. However, the variations will still be within the ranges defined in the rulebook. There will be some minor variations in the walls heights and widths as well but these should not pose any problem for the teams.
The TCs and OCs wish everyone luck and see you all soon in Sydney!!
Best Regards, Asad
