As a former FRC student on 3506 in N.C. and now a part of the Penn State RI3D team itself, I am so hyped to see the pieces of the robot from 3 days all come together in all its hard earned glory!!! Though this year was tougher for me to contribute too due to life situations, since, working up to this moment since 2024 and remembering my FRC times in the past, I have truly appreciated rubbing shoulders with such hardworking fellow teammates and am truly privileged to be a part of this team! It truly would take a paragraph to list off people to shout-out to who preserved to get this done. WE ARE PENN STATE:RI3D
@@theslashmanrc7503 we used a navx instead, and it's on the roborio on the front of the robot. The navx still functions the same even when offcentered
Amazingly done, it combines a few experimental elements such as deep climb and the two claws using the same elevator in one mechanism. I had some concerns about the size of the ball being much too big (about 40cm in diameter) for the robot to fully carry, but after seeing this I’m sold. Outstanding RI3D!
So impressive that people can build highly competent robots just in 3 days now. Ri3D robots in 10 years ago were more like just crap. Congrats from U of M Ri3D team.
I just answered your question on chief Delphi, but for everyone else, here is a copy of my response: Because the cams that push on it have to straddle a bar, and it is easier to mount the cam mechanism in line with the chassis
Hey guys congratulations on such an incredible Ri3D robot. For the deep climb, what gear ratio and motor did you use and how did you design the mechanism that interacts with the cage?
PIDf control and setpoints. I highly recommend looking into it, learning proper PID tuning can greatly improve a robot without the need for additional sensors (if you are using brushless motors)
@@aristeinfeld3687 Yep! We use a PID loop with feed forward to quickly and consistently go to different positions on our elevator and wrist. All of our code is available on GitHub as well! github.com/Ri3D-PSU/Ri3D-2025
Great robot. I see a lot of copying to go into ours. How are you stopping the intake wheels for the algae and coral? Using mechanical switch or sensor?
Thank you! No sensor, just eyes, both intakes are run on a button push. On outtake of coral no input is needed for L2 and L3. With more time we could have tuned to passive outtake to work on L4 as well.
If you look at the shot at 0:22, you can see how the bot looks in starting position. The algae collector is folded in to fit inside the perimeter at the start of the match.
105, although we added ~30lbs of ballast for the climb. With ballast, CG is about an inch from the lift point. That weight is illegal, and if we had more time we would have been able to remove a lot of weight.
Would love to add that double algae intake and coral manipulator to our design!! Is the angle on the falcons in it a contributing factor to the speed at which you intake the algae or more of a consistency thing?
The tilt of the two intake motors is an unintended consequence of adding a horizontal piece of surgical tubing to increase compression force. There is a lot of flexibility in how those are made and we believe the effectiveness would be similar with correctly fabricated vertical motors.
As I understand it, a human has to be the one to shoot the algae into the net. I feel like I've been given conflicting responses on that though, so feel free to correct.
Slamming into the platforms seems a bit aggressive. I would think that sensors to stop that would be part of the requirement to ensure safety in robotics.
Congratulations, you win RI3D
that climb is interesting indeed, having to do such a low climb is new for me all you people in ri3d are so inspirational
The deep cage climb was a really cool challenge! We are so glad you are inspired by us!
Yooo it's the goats
@@ashar682 OMG Hiiii Ashar!!
@PennStateRi3D just curious, where did you guys mount the pigeon?
Is the climb legal? I remember past years didn't allow you to go 2.5 in below the bumpers. Does anyone know the legality of that?

Im a former member of 5160 myself
Since your a part of that RI3D Team, where did you guys put yalls pigeon, or are you even running one?

Great job, truly supporting FRC teams All around the world
The media team that produced this must be a group of super cool and awesome people

Jonah if you're seeing this, I'm super proud of you and love the build, keep it up :)
Thank you Mr. Johnson! I like the build too
I thought I had seen it all in cranberry alarms robot. Truly next level guys.
That one’s so much faster than the others I’ve seen. I wonder if it’s just the drivers skill or they geared it high.
Driver is from THE swerve drive team, so he's pretty good at driving
This. Looks. Sick!! Definitely going to use some inspiration from you guys. Amazing set of engineers! Thanks for all your hard work!
Thank you so much! Our main goal is to inspire others!
now thats what I call an everything bot holyyyyyy
Super impressive and inspiring
Great work, Penn State Ri3D!

dude that deep climb is sick
Love the robot! ♥ from the RustHOUNDS!
Thank you! We love your robot too! Your deep climb is such a good idea!
truly inspirational content
Awesome job!
Why did you guys have the cage rotated 45 degrees? Why not have it more aligned with the frame?
I just answered your question on chief Delphi, but for everyone else, here is a copy of my response: Because the cams that push on it have to straddle a bar, and it is easier to mount the cam mechanism in line with the chassis
@@aristeinfeld3687 Thank you!
Great work!
The climb is insane

Check out our climb showcase! ua-cam.com/video/IP6gVlijUuI/v-deo.html
We ran a 225:1 on two neos.
lmao the deep cage got me stressing
You are really amazing, in elevator how can you make the movement softly start and softly stoped in coding

Hi, per rule R102 isnt the Algae collector wheels wrong?
If you look at the shot at 0:22, you can see how the bot looks in starting position. The algae collector is folded in to fit inside the perimeter at the start of the match.
@@jacobspadt2567 I see it now, thanks!
The season just started😭
Genius
Would it be possible for you to provide your robots total weight and where your robot's center of mass is
105, although we added ~30lbs of ballast for the climb. With ballast, CG is about an inch from the lift point.
That weight is illegal, and if we had more time we would have been able to remove a lot of weight.

Bu bir mühendislik harikası
Can we get a video of this robot cycling a lot of coral?
I’m scared for the competition now
what was the gearing for the deep climb mechanism?
@@leonidas3779 2 neos on 225:1 with max planetary stages 5 5 9. With 9 closest to the motor.
Exactly! But if you try the donut climb on your robot we encourage you to experiment. Different gearing may work better for your robot!
Would love to add that double algae intake and coral manipulator to our design!! Is the angle on the falcons in it a contributing factor to the speed at which you intake the algae or more of a consistency thing?

@@PennStateRi3D Oh lol. Thanks anyway, the surgical tubing also sounds interesting as a way to improve grip.

Can this robot shoot algae into the net?
The algae manipulator cannot really throw the algae. It could be a good modification though!
No
As I understand it, a human has to be the one to shoot the algae into the net. I feel like I've been given conflicting responses on that though, so feel free to correct.
@spencerbair1137nope, the robot can throw it in for some bonus points
@spencerbair1137 both human and robot get 4 points if the algae is shot into the net
