This Season's Game - 2022-23

Regarding the AprilTag implementation, by changing to a lower resolution tag family, teams should be able to detect the tags from further away for a given resolution and use a little less CPU doing so (or process at a higher frame rate). The trade-off is an increase in false detections, which testing has shown can be mitigated by using an appropriate minimum size and more aggressively rejecting tags with bit errors. The updated information is below:

  • Family: The 2023 playing field will use tags from the Tag16h5 family. There will be no tags from any other family on the field.

  • Size: The tags will be approximately an 8 in. square. This means that the black square is 6 in. from outside to outside and should be printable by teams on any standard printer.

  • Material: The tags on the playing field will be made from matte vinyl to provide a blend of durability and resistance to glare and reflections. Based on testing, expect teams will be able to reliably practice with printed paper targets, but there are plans to investigate making official targets available for teams to purchase.

Rule Changes:

Modify R302-E, to permit teams to use items created before Kickoff if they are “functionally equivalent” to a COTS item. Functionally equivalent items are items that closely resemble a COTS item in both form and function. Functional equivalents should be made using similar materials to the COTS original.

Modify R406: Change the color requirement in R406 from requiring a white outline to requiring that the entire number must be white.

Modify R408-A - The pool noodle specification in R408-A from “2.5 in (nominal)” to “2.5 in +/- .25 in”.

Modify R501 and R504 - Add a line into the tables in R501 and R504 permitting any brushed motor linear actuator downstream of a 20A breaker and legal motor controller.

Modify R602 - Clarify that COTS computing devices are intended to be devices collecting or processing sensor information and simply having a microcontroller (e.g., a “smart” flashlight) does not make a device a COTS computing device.

Modify R619 - Add Snap Action AT2-A breakers to R619, values 40A and below.
