for gf they are able to cancel their dr4b's weight using rubber bands so they can go really fast with one motor, but for us (15534), we cant do that with linear slides so we had to use two motors. we just use fast gear ratios, minimize weight on the lift, and then use a PIDF controller to make movements smooth. we also automate everything so we can optimize the lift speed
once you get to like 8 stones towers start becoming really unstable, even with 2x2 base. I can't really see towers going that much higher than 13 at worlds (which is steve's max), they'll just become really unstable and risky at that point. It'll take a lot longer to stack on them and they are super high to knock over. Plus, the tolerance on the stones is terrible, so if you get a bad stone low in the stack you're screwed.
They said on reddit a while back that they felt their swerve was too complex and more risky than a mecanum drive and they would prefer to use the more reliable mec over swerve and that it was just a fun off season project for them
Differential swerve is very good at pushing power, but it's really hard to maneuver and make fine adjustments as the module turning time really begins to make its presence known. In addition, they said they had some issues with skipping gears on the modules, so that could lead to an inconsistent drivetrain.
It's 10 high with one capstone. All the 140 points are like this: 61 points Auton is two skystones and 3 stones on repositioned foundation with one robot navigated. 44 points teleop is 10 stones delivered, 14 on foundation, skyscraper 10 high, 35 points endgame is one capstone on 10 high skyscraper and one robot parked. With more points from the alliance partner (already did a great job delivering stones and staying out of the way and trying to cap 10 high) this match could have been 155 (+5 for auton navigating, +5 for capstone anywhere on foundation, +5 for parking).
What aluminium extrusion is used for the lift? I have really only seen that type of lift successful in vex games with there more lightweight channels compared to the textrix/actobotics/gobuilda c channels
They did not use vision; they just made pre-programmed paths based on where they found the blocks usually got knocked to in testing. This is particularly easy for them because their intake has such a wide margin for error.
ElectricWizzz we can drop our capstone it stays in the robot for hole game. We can score 63 points by ourselves. My team number is 7093 and 8413. Looking forward to meet you guys
@@drizzleandpour7819im not sure what match, maybe im wrong. But the only reason they got so many points was because they ramed up a creek's and broke it yet didnt get penalised
Thank you guys for inspiring my team! To kill ourselves come on man what was that
Wooow lmao
how did you make your rev slides so fast?
you have achieved comedy
Gluten Free’s alliance’s lift moves so fast, how do they do that?

You can spring load both linear slides and 4bar to cancel gravity.
@@vincentx22 are urs telescopically strung? no way you can achieve that speed without it
@@nicklarson2173 wdym by telescopically strung? we just string the lift continuously if thats what you mean
@@vincentx22 smart idea
What about six stones in autonomous? :)
That autos insane
That red stacking not looks like the design of the vex in the zone and it's freaking fantastic xD
The lift is a double reverse four bar, and it is definitely powered by motors, not servos (unless they did something weird)
Looks a lot like VEX robots
They actually powered by motors through a pretty big brain linkage that makes the lift completely non-backdriveable when its at max extension
Hey! 15772, that’s my team. As you can see we got smoked during finals... 🙃
at least ur bot looks nice
Well gluten free is like the best team in the world
my teammate suggested grabbing all 6 of the stones during autonomous as a joke... but this team... this team.......
Was Gluten Free's lift inspired by the Vex lifts in the cone stacking game?
I love how this had like 210 views even before it was listed
What’s the advantage of the double reverse 4 bar? Is it faster than slides? Do you want to be a little shaky?
There's really not much advantage except simplicity
I can't agree with GF design choice on this one. They won't be able to stack high enough to be competitive at worlds
@@nic6909 there auto alone makes the robot viable

How did they do that good of an autonomous
They dont sleep
odometry
What Mecanum wheels do you use? What motors?
100mm Bearing Based Nexus Mecanum Wheels, 19.2:1 Neverest Orbitals
How come you ended up going with mechanum wheels over the differential swerve you showed? Great robot btw! What do you use to power your lift? Thanks

That autonomous is KILLER
Do you have a fusion version of it?
How are you guys powering your lift? From the bottom, middle or top? I think it’s at the top but I can’t tell
What was the auto score?
So did they score tower for how high it was or how many stones were under the cap?

It's not like a kit extrusion, it's just custom made out of aluminum
Did you use OpenCV Vuforia Tensorflow or something else???
@Braeden Cullen Would love to see some of your sample code if you could post your link...Thank you!!!
@Braeden Cullen that's not being a gracious professional smh
That would be awesome if I could could get some sample code! Thanks so much!
Braeden Cullen any chance you could post the sample code you had mentioned?
Its 160 points...
In what match? Data force and black forest did 149 on saturday, and before that it was this 140 match
Wow, the vision to get the rest of the stones is 👌
They did not use vision; they just made pre-programmed paths based on where they found the blocks usually got knocked to in testing. This is particularly easy for them because their intake has such a wide margin for error.
@@alkali836 but surely the blocks would not have been knocked that consistently
👌
Zypex that’s what they said at least
They confirmed absolutely no vision beyond checking the random order. It took hours of tuning and forgiving paths and intake.
Is everybody copying that same design!?!?
hey i was the skystone reseter for that skirmish
Of course it’s gluten free
Gonna meet them this weak at states our robot can fead 10 blocks in 30 seconds but we cant stack. Wish us luck ✌🏽😅
High priority: try to drop a capstone off... ideally with some height.
ElectricWizzz we can drop our capstone it stays in the robot for hole game. We can score 63 points by ourselves. My team number is 7093 and 8413. Looking forward to meet you guys
I would like to show our robot so you can give us a opinion about it
I would be mad but I don’t think y’all go to Texas for worlds so I’m still fine. 😂
Tristan Tyson *sighs* lucky you…
DarthTauntaun it’s okay. Competition in North Carolina is intense so I’m honestly just hoping to go to worlds for the first time.
big rip for mass teams
Yeah 11115 goes to Detroit not Houston.
Tristan Tyson Hey, NC gang!
I thoight the record was 160
