mecanum drive. yes? no? why?

Here it is: the tutorial! it's not particularly in depth but it's the way we did it and I hope you guys learn something from it! If you need help or have any other questions feel free to ask!

I’m wondering if any teams have started using generative AI for programming robots. Would love to hear some pros and cons.

We ordered our krakens in December and so far we haven't received any word on when they're coming! We have a Week 1 regional and we need them here yesterday.

Has anyone got their krakens yet?

Hello, I am Luis, the captain of the Faraday5696 team or at least that used to be the number, this year we will compete as rookies with the number 10565, we are from Villahermosa Tabasco Mexico, we are a really old team, but my generation of this one has not had very good advice, direction from tecmilenio, got us participation in frc, but due to coach and administration problems, We have no idea how an FRC robot is made, and our financial resources are very limited, we have competed in FTC in two seasons but for the first time we will participate in the Torreon Coahuila regional in Mexico, this March 21, and we wanted to ask If there is any team that has the possibility of supporting us either with constant advice, and mainly with pieces that have leftovers at their disposal or some type of sponsorship, that helps us to be able to compete in a better way this season, I will be attentive to all your answers and thank you very much.

My team has 2 robots, and we’re using last year’s as a “programming twin” to develop and test code as we build this year’s one. Last year’s has MK4i swerve modules with Neo motors, and we got yagsl running on them in about an hour by carefully following the setup docs. This year’s robot has the same MK4i modules but with Kraken x60’s. We tried for a full week to get yagsl up and running, but in the end, we could only control the drive motors; the turn motors would never budge. We setup a code base with the CTRE Phoenix Tuner and can drive the robot that way. I had wanted yagsl on both robots to minimize risk in transferring code from one to the other. Before my coders fully give up on yagsl for our new robot, I wanted to start by seeing if any team has gotten it driving with our setup (MK4i with Kraken x60 motors)? I know that the CTRE drive libraries give extra performance boosts. I’d still like to try yagsl…

We thought of using a linear actuator since it's significantly lighter than a moter with 3 gearboxes, not to mention you have to gear it more. Rn it picks up our proto pretty well (about 3 to 4 in off the ground)

Our team has been trying to build a Swerve Drive base using the YAGSL Library. We have CANcoders with MK4i swerve modules, a NAVX (USB) and SparkMAXes on NEOs. We are a new team to swerve Drive and we keep running into jittering when turning the wheels 90 degrees. We have tried some basic troubleshooting but anything past that our coders are stumped. Any kind of advise or direction would be awesome. Thanks!

hello! my team and i are working on our climber design and had a question. do we need to hold the climb for 5 seconds after the buzzer for it to be valid like last year or is it fine if we're up just for when it goes off?

Hi! So, I am interested in singing the national anthem at a regional but I don't know where to do that or how to. Is there a place to sign up or are teams just asked? If there is an online sign-up/audition could you send the link for that? Thank you!

Have any teams had much success with shooting algae into the net? Curious as our team has gone through many prototypes and can't get one to work.

Was wondering the cage dimensions and the diameter of the hole in the bottom.

So we just finished rigging our 3 stage elevator and it works ridiculously well. I haven't really found any particularly great videos or information on how to rig one, so I was wondering if others would like to see something like that?

In Reefscape, there seems to be a gigantic pool of of starting point, scoring location, and reloading zone permutations that a robot can follow in auto. We'd rather not spend hours and hours building each permutation as a PathPlanner auto and trusting the drivers to choose from the daunting chooser list if we can avoid it.

One solution I thought of was a system in which drivers could assemble the steps of a routine just before the match, using pre-made "pieces" of paths to build a complete routine. It would help us be as versatile as possible, especially during qualifications.

I don't currently know of any existing tools/libraries we could use for this. Any suggestions? We use Shuffleboard for our dashboard, but open to using something else if needed to accomplish this.

Someone could help me in FRC CODE? Basically i need a coach for teach me FRC CODE, I'II start in a team, and be programmer.

Hi everyone! A small group of our 4859 team are in an engineering class together and are working on a parade bot for it. From our process, we want to document what we do and create training material, and we’d like some feedback from everyone about what training material they would find most beneficial. If you could take a few minutes to fill out the form, that would be amazing! https://forms.gle/2hJ7wrpKaECbUEeL7

Episode Description:

In this ACTION PACKED Episode the interview panel provides additional input to the Reefscape Game, build season thus far and how their team strategies might play out during the competitive season. In addition, the interview panel also speaks to the forming of a new non-profit organization FOCUSED on helping newer teams level up their competitiveness and capabilities but providing access to parts and tools through donations to the non-profit by teams like YOURS! The Red Alliance, started by Tim Lawrence, Bruce Stone, Josh Dunston and myself are focused on reuse of parts teams no longer need and providing those to the teams that need them the most! If your team would like to donate parts and tools to the Red Alliance please visit the website below or email me at robozonepodcast@gmail.com and we will get the Red Alliance in touch with YOU!

If a team works hard and doesn’t advance to the World Championship in Houston, TX, can a team travel to visit and watch as public? Or, can they volunteer for a day? Or, attend exhibits and conference classes?

I have been to the World Championships in St. Louis and Detroit. I shared my experiences. The students want to experience the atmosphere and see how teams get to that level. We have a sponsor who would help us with travel expenses. I think it would be a cool experience, but the regional partner is unsure of how it work for non-competing teams, visitors or volunteering.

I wanted to get a picture like this for a while. I've had interest in the history of robotics controllers and was inspired to research about all of these control systems. I would like to see peoples past experiences with these systems. Here is the control systems with its corresponding PDP. (And a singular spike :) )

hi im using a can config for my mecanum chasis, how can i invert the motors of the chasis?? setinverted.true do not work

Can we put rubber bands on our bot?

My time was a rookie the previous year and we are currently in our second year. The award criteria says “The purpose of this award is to recognize new teams or teams that have new beginnings. Teams do not have to be in their first year. For example, the award could recognize a team in their second or third year who has undergone significant growth or succeeded despite challenges.” Then it also says “This could be the result of being a new team, or a team with recent turnover in membership”. So is my team eligible or not? I think the recent turn over in membership means that when a team takes a break from FRC then rejoins? Am I right? Please help!

Hi, we have a neo vortex motor paired with a spark flex motor controller connected to the west coast elevator system and right as we turned on the robot the motor started smoking and sparking until the robot was shut off two seconds later. All of the other motors acted fine, and the rest of the robot booted up as usual. We are out of ideas, anything would help. Thanks

Trying mecanum wheels this year (they do need cleaned this year because they are used before)

Does anybody have a resource list for mocking up field components in wood and pvc?

Our team bought a Limelight 3 and are trying to update it to the new version but it won’t show up on the balenaEtcher. We have it hooked up to sufficient power and connected to the radio. Anyone know why this is?

Is anyone also thinking of using photonvision for coral detection to automate scoring on the reef?
