Hi Gluten Free, I really admire your robot, both mechanically and from a software standpoint. I see that you guys have a mostly Actobotics drive train, but I also see a lot of REV extrusions. It is hard to tell from this video, but how did you guys use both systems at once? The hole patterns don't seem to match. I can see the benefits of both systems, with Actobotics being tough and good as a base, and REV being smaller but versatile.
Mainly we dont use the middle screw to keep the sliders in place, weve found that it slightly deforms it and introduces friction. On top of that we use white lithium grease, which helps a little. Finally, if you look closely at the robot when the scoring lift us extended, we have guide rails that make it very stable at the bottom of the range for a reliable interface with the intake for exchanging.
what are those structural extrusions on your robot? not the ones used for extension, but the ones holding the panels on. I just can't figure out how you connect those to whatever u-channel you use.
The only extrusions we used throughout the robot are rev 15mm extrusion and actobotics x rail. x rail was only used on the linear actuator for the hang mechanism, so everything else you see is rev 15mm
Thanks for the response! You guys are using Gobilda channel then? Or otherwise how did you connect the rev (metric) extrusions to non-metric u-channel?
@@theclueless11212 All the channels are actobotics, but we cut the rev extrusions to custom lengths with a chop saw, that way we can mix imperial and metric systems
Our intake slides our aluminum drawer slides from Ebay. I cant tell you much more than that because they came with no information as to who the manufacturer was. They have about the same extension/weight ratio as regular drawer slides, but are much stronger than regular drawer slides for the same weight since they are thick aluminum.
What mecanum wheels are you using, and what motors do you use for your drivetrain. Also, are the drivetrsin direct driven by rhe motors (and if not what gear ratio)?
@@FTCFROGbots can you please explain to me how that works/is possible I am having a very hard time understanding how to construct a pulley like that. Thank you for your help.
@@sasmitagarwal3638 I don't remember exactly how they did it, but if I recall correctly it's your standard "double-spool" design, but with 2 cords coming off each half.
@@FTCFROGbots But how would that work if the two slides are on opposite sides of the robot, you would need retraction and extension on two different sides, making for at least two motors, one for each side, each with the standard "double-spool" design
Yo I’m from team 5962. I didn’t go with my team to worlds, but I saw the match you guys had together and how they played defense while you guys scored was beautiful. As well as how well your autonomouses worked together. I think they’d be an amazing second pick for you guys to go onto elims. I don’t only say that because I’m from their team, but because they’re super reliable and have never failed in any rounds. sadly they’ve gotten unlucky with some of their alliance partners though. I wish you guys luck and hope for the best!
I asked them and they said that they use algorithms to determine where they need to be to score in the lander, which is how they move when scoring. I believe the collection is driver controlled.
@@alexpollock5147 Yep, that all sounds right. Our team also figured out how to do this pretty well last year and almost perfected it in our free time since then.
It sure would be nice if Gluten Free truly designed, built and programmed their own robots instead of having their coach do it for them. I thought that was the intent of the First competitions. Having coaches do the work and the kids just drive the robot in competition defeats the entire intent of the competition. The teams that actually design, build and program their own robots get something out of this competition that will help them for their entire lives, but the teams that have their coaches do the work will regret it in the future. A trophy is only meaningful if you actually earned it, and in a STEM engineering competition you must actually do the work for it to benefit you.
I agree, but the only time I see the coaches helping is when the student is struggling to solve the problem, then the coaches should help out, but not have the coaches do the work for the students thats outright cheating and will not help out in the future so yea i agree with your statement.
Kraken Pinion: We the best

_CandySour _ this was awesome to witness! They did what everyone thought was impossible
Game Design Committee next year: No scoring cap possible so that GF can literally score infinite points
2 years* skystone had a cap because of the limit of stones the human player had
Holy... That's the coolest competition robot I've ever seen..
That's sweet man! Looks like alot of time and effort, well done
This is absolutely insane omg i love your robot
Our team decided we would do something similar to this. Then we tried it... let’s just our robot doesn’t do this
story of my life
congrats on the World Champion!
The best robot by far
Amazing!! great job guys
Actually very epic frc kid approves
THAT IS INSANE
Wow! I competed in this too! I was team 10058 wild cards and I had a whole lot of fun! Nice robot too!
We were happy to score 16
Amazing! I'll see you at Worlds!

Nice actuator
perfect
good luck at worlds
steven, how did you make your rev slides fast. :0
What sorcery did you do on the REV slides to make them so smooth?
I want know too..
Yeah, me too
Same
Ours couldn’t even extend all the wat

They run nexus mecanums off Andymark Orbital 20:1s. They use belt in channel to drive the wheels.
Your FTC car is very nice! Where can I buy the horizontal and oblique multi-level track of the FTC car? What specifications are they, thank you.
@ElectricWizzz I was wondering how you string your slides?
They power them on both sides from a single spool with 4 separate cords. (2 for extension and 2 for retraction, one of each for each side)

what team are you guys
They're 11115 Gluten Free
What in the actual fuck how
But how
*S U C C*
Wait a second... Are you guys using autonomous positioning for dumping and then having a driver manually tweaking the positioning values? (from #7750)
On the Tellin' Em (by NuttyNeo) show tonight, there's a q and a and you can ask questions live, but the answer is yes.
Thank you for your answer! I will try to make the stream.

They are the best ftc (First Tech Challenge) robotics team in the world
search up rover ruckus
Not to flex on anyone, BUT....
Designed and built by middle school kids, right?
I think its 2 high schoolers.
2 high schoolers
yeah, just not yours :)
If you look at their past videos, this should be very obvious.
Are you interested in a collaboration with a rookie Romanian team ?

Rookie team garbage. Can’t even get 32 cycles. Should call yourself “Victory Free”
You better be joking or else that’s not GP at all. Not acceptable.
@@YTN1112 lol he's obviously joking! They are clearly the best team.
