@JoshuaThe-xp2jb Those are gobilda viper slides.

I meant for the thing that is connected to the horizontal slides that like the servos/motors power on the horizontal extension like the linkage extension I think it is called

@@JoshuaThe-xp2jb 1102 series flat beams, also from GoBILDA.

They did. They even acknowledged that it would've been a state record if they fixed it

it is a penalty, check the game manual

@@ziezster8470 yes, it absolutely is. We just wanted to release this before the league tournament, so we used any footage we had.

@@pointyflyer155 the wedge was derived off of a sample CAD, so it pretty much is just an insert with the exact dimensions of a sample. The main problem was getting the exact distance between each triangle, and how annoying it was for drivers to pick up.

@@carlosdemarco3470 we don’t currently have a full cad of the robot. Sorry.

@@complexity_ We currently have 3 sets of slides for the robot. Two are used in the intake, one for the elevator. The elevator uses continuous, (default gobilda viper slide kit with a better motor) and the intake has the arm structures on it to move it.

@@FirestormRobotics Thanks!

@Olive807 our intake would sometimes get stuck on top of samples, so we push them out of the way so that doesn’t happen.

@@derpii5311 thank you!

I use to be on the Firestorm FRC team (6341) before it fell apart. FTC is quite different.

@@leohai6700 we use gobilda servos, but only run them at 30% speed since the color sensors are very slow.

@@FirestormRoboticshow are you able to lower the speed of gobilda servos? Is there some kinda of hardware extension

​@privyao0 they are running .3 power in cr mode. Hope this helps!

It's actually a lot simpler than it looks. (I'm assuming you guys are using the Limelight 3A, as we are). Basically, the limelight has a pipeline that detects the sample by color. This pipeline can be configured by following the limelight documentation (docs.limelightvision.io/docs/docs-limelight/pipeline-retro/color-filtering) In the actual code, it looks at the nearest sample and rotates the robot to where it is centered with the sample. Since the limelight gives you how many degrees off the sample is from being centered, we've just created a PID loop that multiplies the degrees off by a P term, and we set the robot to turn at that speed. So, if it is at 0 degrees, the robot doesn't turn.

@@FirestormRobotics ah thank you!

Me too, we need to know how to do it

An 80 point auto sucks to you?

@@JHolmes-v8g Yeah but i'm on the team so I know we can do better.

@@W.E-Edits Yeah but I'm the programmer and I know you engineers can do better

Your team can do what 16+ samples in a game? Can it do specimens? Does it hang? Teamed up with a specimen heavy robot you're probably unstoppable.

I just looked at your statistics. Ranked #1 but have had issues overall with allied teleop scoring, but that looks like a league wide issue. No doubt you'll win your league tournament. Good luck going into State!!

We have an Axon mini on our depositor.

Like your 600lb ass could even work if you wanted

@druthulu8360 me? 600lbs hahaha, I'm a mechanic homie I make sure ur car go vroom, I took 3 years of classes and determination to have a better paying job, ots really that simple... Amazon McDonald's burger king dennys Walmart etc. Are supposed to be entry level jobs and os supposed to be mostly worked by highschool and college kids

This is a children's robotics competition. Calm down.

???

Mecanun wheels

@@northstarai5640 this is mecanum, not swerve. It functions very similarly, but slips and gets pushed around a lot more easily. The only reason we use it is that it uses fewer motors and FTC isn’t contact heavy.

@FirestormRobotics ohh okay, thank you for the correction. Very cool!

Are you using any odometry?

It is interesting to see ftc focus on robot ability over the brute force tactics seen during powerplay. Robots this season almost never have to touch each other.

@@MrMegamike2k yes, we are using odometry. Yeah I mean with this game, there isn’t much you can do for defense, especially with the submersible and how easy it is to get penalized.

@@ADobbin1 unfortunately there’s no yeeting of game elements. (G433)

This is an FTC challenge. It’s for middle to high school student, they build and compete robots

Could you cite the section in the manual?

I can’t find a specific mention in the manual, plus it isn’t that different from extending our intake to move samples around. Also, I we control the sample for less than 3 seconds (momentary) and aren’t launching samples either.

It's legal. Even though you do control multiple scoring elements it's for a short amount of time. If it were close to three seconds that's when you get penalized

Technically the sample is counted twice at the end of the game. But also 80 sounds cooler :)

@ Yeah lol

80 does sound cooler, but it's still only 40 points for autonomous. Amazing job nevertheless!!

No, you may control any number of samples in the submersible zone (rule G410-A in the game manual).

Try emailing one of our mentors (elijah@cherokeemakerspace.org). I currently don’t have access to Onshape since I’m on vacation.

Thanks

Not well enough for us to confidently use them in matches though. The mechanism is still kinda janky.

@ARandomMidnight the whole robot backs up. Basically, the claw is two slabs of polycarbonate with a 3d print to keep them from falling off. When the robot backs onto the specimen, the polycarb flexes out of the way, then clamps onto the specimen. When we are releasing on the high rung, the opposite occurs.

Yep! That’s Luke! Not only is he the only programmer, he is also the driver!

We know. This practice for the drivers on the in-competition practice field.

I believe those are linkages that power their slides which allow them to extend forward, but also serve to aid in cable management- hope this helps!

On our first intake iteration (comps 1-2), we actually had only one slide and a smaller intake. Our main issue was that the connection was super janky and inconsistent. We decided to completely revamp the intake for the third comp, and one servo was too little to have it extend at a reasonable speed, so we just added a second connection.

Yeah. In our last comp, we had the same thing happen matches 4 and 5. We still have our 0+4 as a backup for these situations, although there aren’t a ton of teams who have a consistent 2 or more specimen auto in our league.

@FirestormRobotics lucky. My league is pretty stacked
