Hello FRC community!
This is gonna be the Official Build Thread of FRC team 639 Code Red Robotics from Ithaca High School, NY.
This is our website: https://www.team639.org/
This is the first time my team ever made a build thread in the teams 22 year history
Although it’s almost 3 weeks in build, it’s still not too late~
This is the general time-line what we currently settled on:
Week 1: made prototype teams and did prototyping
Week 2: chose designs, broke into subsystem subteams, started CADing
Week 3-Now : CAD!
Brief Overview of our current designs:
Current Subteams we have
Hey neighbors!
If you need some ideas on how to flesh out your build thread with details, feel free to take a look through ours: FRC 3181 Pittsford Robotics 2024 Build Thread
Excited to see what you come up with. See you at both FLR and TVR!
thank you so much!
Media team Cooked!
End of Week 3 Recap:
Hello there!
Today is the planned finish date for all CAD of the robot, and I think it’s a success!
Here’s a brief description of the subsystems of our robot
Intake:
Intake in the robot:
Dual roller under-bumper intake powered by a Neo, attached to a 1-stage MaxPlannetary.
Launcher:
One 4" Thrifty bot Solid Urethane Wheel on each side as launcher wheels, each powered by a kraken separately.
The Launcher have a dual-roller indexer at the back to manipulate the note from ground intake and feed it to the launcher
Pivot:
Will use one Neo with 100:1 CIM sport gearbox and chain to pivot
Pivots the shooter in 3 positions:
Load note from ground intake:
Shoot into speaker:
Shoot into Amp
Climb:
Trap:
So far we don’t have a specific mechanism devote specifically for trap, but we might add a mechanism later devoted into opening the trap door, so we can shoot up into the trap
The build time-management have been so good this season! We only need to polish the CAD a very little bit next Monday, and we will start machining!
Alright, 10 days later lol.
Havn’t tracked the time for quite a while, here’s what happened in the past days:
CAD have been finalized last weekend, now we’re fully building the robot!
Here’s what have been build so far:
28*28 Max Swerve drivetrain with Electronics:
Support Frame and “Arm” for the shooter:
Shooter Motor + Wheel mounting plate:
Ground intake almost finished:
Here’s more things that happened in these 3 days!
Firstly, the ground intake have been put on the bot and worked first try
Secondly, we got some very nice 3d printed gears, that allows us to test out the feeder for the launcher. The pivot also got fully assembled and got a rev-through-bore-encoder, so we can play around with it as well
For visoins, we got out note detection working very smoothly and reliably, and also got integrated with the robot as well 
We are hopping to get the full robot assembled soon, and we are definately starting full time robot programming this week.
OHOHOHOHOHOHOHOHOH
Yes, we have 7 cameras on the robot, 1 limelight for note detection, 6 jeston cameras for apriltags, vision team is going all in
(Ok, I just realised I should been posting out build progress on a topic under Open-alliance tag instead of General Forum, but I think it’ve been too long for me to change the tag lol)
Today we had a short productive meeting and had our first full-time robot testing.
Here’s a picture of the fully wired robot:
Here’s a video of the robot’s first launcher test:
We are currently using 3d printed TPU belts for the shooter, therefore the Krakens for the shooter is running at a very low speed.
We are getting our good-belts soon, and we’re hoping we can spin our shooter at more aggressive speeds
It’ve been kinda quiet in the build thread in the past few weeks ,but not a quiet time for the team
We finished wiring the robot, and today we have successfully executed basic code for our robot!!!
We can also AMP!
Alright, quick update for what we did in the past few days~
We tested out our climb mechanism yesterday. We are able to climb really fast, but the climbing mechanism isn’t perfectly at our CG so we “Swing” on the chain quite a bit.
Programmers also made auto note pickup working using limeliight and drive-to-point-relative-to-robot.
We also further improved our code, and are able to do consistant subwoofer shots:
Our first game wll be starting next Thursday at FLR. I’m personally really excited
Alr, quick update of finger lake regional!
Our bot shoots and amps and climb, hoora!
This is our best game:
we ranked 28 out of 50 at FLR, but we’re cooking hard and we’re sure going to perform way better this weed at Tech Valley Reginal
Last weekend We competed in Tech Valley Regional, was ranked #5, alliance captain of the 4th alliance, and have a qualification record of 8-1-0, the highest performance in the team’s history.
We had technical difficulties for our 2nd playoff, our tread fell off 1 swerve wheel, it was really unfortunate.
Overall, it was a great season! Everyone on the team is really aswome, and it was a true honor to work with all of them.
We had a feedback meeting yesterday, and I’m excited for next season.
