ARENAS used in week 1 events suffered severe damage due to distinct, violent, and extreme impacts by ROBOTS on the FIELD border. We’d like to use this opportunity to remind DRIVE TEAMS of G415. Head REFEREES are instructed to apply G415 for these scenarios to protect the integrity of the ARENA (and the viability of the event); violently ramming into the FIELD border or other element is likely to result in damage and will be penalized as such.
Does anyone have any pointers to videos that show “distinct, violent, and extreme impacts by ROBOTS on the FIELD border” that this might be referring to?
ok, so this seems to resolve the tech fouls in israel thread, greater than momentary and repeated seems to be implying that in auto it’s fine if you brush a note while already controlling one?
edit: this is incorrect
The plastic wall actually cracked based on a picture of the aftermath.
G409 only applies in teleop. TU16 doesn’t address G403 which governs multiple NOTES in AUTO
… GAME PIECE CONTROLLED by either ROBOT …
“boop” meta incoming
Any control devices worn or held by their HUMAN PLAYERS and/or DRIVERS during the MATCH must be disconnected from or set on or beside the OPERATOR CONSOLE before the MATCH can begin.
Good change, as this is essentially how it’s always been enforced for things like gamepads. We certainly don’t want teams being forced to disconnect their gamepads before the match. I wonder if this is just a case where after teams started widely using gamepads instead of joysticks, the rule wording was just never updated.
Finals 1 of Clackamas, top right, just to the left of the entry point, 3674 manages to fling the zipties holding the polycarb towards the AV table, knocking the polycarb from the field entirely. This was the only one at Clack I am directly aware of, but im not sure its what the manual means.
No comment on apriltags.
Looks like teams will have to learn to adapt (not unexpected).
I noticed that language earlier in the season and thought the same thing. Glad that they fixed it!
So…
Carpets are failing.
Bumpers are failing.
Robot frames are failing.
The Field is failing.
Perhaps it’s time to take a step back and reevaluate the place of brushless motors in FRC. They’re great for performance sure, but all signs point to us exceeded the limits of the arena and robot construction as we continue to build faster and faster 130lb+ bowling balls.
A team update that says ‘don’t do that’ doesn’t actually accomplish protecting the fields.
2006 ‘fast’ robot: ~10 fps, 150lbs → 31.61 J kinetic energy.
2024 ‘fast’ robot: ~22 fps, 130 lbs → 60.26 J kinetic energy.
That extra ~29 J has to go somewhere, and it’s into the carpets, the field, and the robot frames.
two of those things are entirely in the control of the teams. well, honestly, all of them are. Is it the tool or how it’s being used?
If anyone that reads this has a failed 2x1x1/8" frame rail or bumper from last week, please post it in this thread.
I’ve seen at least a dozen. We are way past reasonable.
sure, I’ll wait.
I had a team at the event I was at this weekend had their frame brake in three places.
Thickwall 2x1 front rail supported by 1/4” Al plates on either side, significant bending after the playoffs run at NCWAK
Plus 24x failed 3/16in aluminum rivets on a single intake hit.
I’m totally okay with robots getting less insanely fast. It is just another design constraint to work within that every type of motorsport or engineering competition manages for the sake of safety and reasonableness, and the 3DP wheel arms races is exhausting on top of it all.
