Cranberry Alarm 2024

It is my great pleasure to announce that Cranberry Alarm will be back for the 2024 Ri3D season! We had a blast last year, and are hoping to make this season even better!

Speaking of better… one thing we struggled with a bit last year, having such a small team, was balancing time spent on actually designing and building the robot, versus time we needed to spend on content creation, especially making videos for you all. This year, to help alleviate some of that stress, as well as help us produce both more and better content for you all, we’ve partnered with First Updates Now (FUN)! @Tyler_Olds and his team will be with us on-site as we dive into the 2024 game. We’re all extremely excited to be able to work with the FUN team, and share our experience with a wider audience!

Speaking of FUN, we’ll be uploading testing, system overview, and daily recap videos to the FUN YouTube channel, as well as live streaming our work on their YouTube live stream, so subscribe there to keep up-to-date with our progress!

In addition, we’re hoping to post some behind-the-scenes/bonus content kinds of things to our YouTube channel, so be sure to subscribe there as well!

It sounds cliché, but we really could not do this each year without the amazing support of our sponsors! Thank you to each and every one of them!

About Us

Cranberry Alarm is a small second-year Ri3D team formed of alumni and mentors in Greenwood, Indiana. Our goal is to be a resource to teams in our area and around the world, by displaying how to easily and efficiently build a competitive robot with accessible resources and materials. We want to be an inspiration for FRC teams, and to help students better succeed in their FRC careers and beyond.

Last year, we were able to build a competitive robot, Rattlesnake, being judged as the number 1 Ri3D bot in 2023 by FUN, as well as winning the 2023 Indy R.A.G.E. event. We have over 35 years of combined FRC experience, including 8+ years of Ri3D experience from various teams.

We are hosted by 1741 - Red Alert Robotics, with the support of the Red Alert Robotics Parent Organization and Red Alert mentors.

If you're in the Indianapolis area during Ri3D, feel free to send me a DM; we'd love for you to stop by and say hi!

We're all super excited for this year's game!

Thanks @Dracco FUN is excited to bring a crew down to Cranberry Alarm to feature this awesome team!

You can expect a couple dozen videos to be posted here and other platforms documenting and detailing CA’s build process with the goal to help educate and inspire FRC teams. This ranges from strategy, to prototyping, testing, assembly and beyond.

As Jordan mentioned: You can find the current stream each day at https://youtube.com/firstupdatesnow/live (this way you don’t need the exact URL for each stream/day).

YouTube should allow for more accessibility for teams plus we have mid-roll YT ads disabled which is trickier to do on Twitch. All live shows for FUN for CRESCENDO will more than likely be on YouTube this year.

Feel free to ask questions any time during the stream and we will also have live Recap overviews each day where CA will stop building to take time to showcase their progress, answer questions from the live chat and also provide giveaways live on stream!

Here’s the current stream schedule (all times US Eastern UTC-05:00)

Saturday:
1:30pm Stream start
8:00pm FRC Roundup: Breaking down CRESCENDO Strategies
9:00pm Ri3D Daily Recap & Q&A

When you say that the human player station can throw out game pieces at 5:30 ish in the strategy breakdown doesn’t G429 or G430 stop this?

If you have a chance, it would be cool to see how the NOTE performs with having shooting wheels on both sides(no spin) vs having shooting wheels just on one side(lots of spin) or even a combination with two sides but one is going faster than the other.

The first thing I thought of when I saw the NOTES was 2013’s frisbees, and I was wondering how close they perform to the frisbees in terms of spin making them more stable in the air.

Also, I remember from our testing in FTC 2020 that a single wheel on each side gave very poor flight characteristics (a lot of variability in height I think from the ring pitching up and down in flight).

https://youtu.be/IdYKodhMz1A Reis from Cranberry Alarm Ri3D demonstrates Note game piece interactions with the AM14U5 Chassis and 1" and 2" bumper heights. 1" had promising results but did damage the Note while the 2" bumper height resulted in stuck Note pieces.

I think the video is currently private, I can’t see it. Or it is in the process of uploading? \o/

Fixed, thanks.

I would be really interested in a video of the interaction of NOTES being ejected/dropped from the source.

How do they hit the ground? Do they roll? How far can they be sent out to try and shorten cycle times assuming a ground pickup?

The AMP delivery prototyping on the stream right now is an absolute gold mine for teams who don’t have the time to prototype ‘evertying’.
