Since most teams do not get an actual field to touch and play with at kickoff, the field interaction videos have always been really helpful.
In recent years FIRST have started filming their own field interaction videos, which are very helpful, but I always find the team filmed ones super helpful as well: since the teams usually kick the field around in a more realistic way, it really helps build an intuitive understanding of the field and it’s elements.
In the past, GUS 228 has filmed some awesome field interaction videos:
Maybe GUS filmed a video and haven’t gotten around to posting it yet?
Maybe your team filmed one and could upload one?
This would really be super helpful for everyone without access to an official field, so if you have something filmed a lot of people would appreciate you uploading it!
Since our team doesn’t really have any field elements completed (as I assume most teams don’t have much made), what I personally have been doing is skimming through the robot in three days live streams and watching how their prototypes are interacting with the field. I have spent a lot of time watching how the new Andymark tank treads have been getting over the various defenses, and they seem to be working pretty well. With some looking through other RI3D threads, you will probably be able to find live stream links until you have access to some field elements to practice with using your own prototypes/mechanisms.
