We're Done, Redux!

Boop... boop... ... boop!


And, that's a wrap. For real this time! Our robot skills challenge videos for 2021 are submitted, the "official" season with the robot has come to an end.


One final, last time, I promise - what a strange year. No competition, no fanfare. With a middle of the day Thursday deadline, we basically had a Slack post saying "Grats, we submitted!", and with that, the season was over.


What a year though - so proud of the students, mentors, school, and well, most of humanity anyway. Great job CyberKnights, I believe it is now naptime.

Bring-Down to Bring-Up

Getting set up for the challenge runs.
And it looks good with the non-legal black bumpers!


One week to go in this season. Ugh, I hate to say it again, but what a weird seasons this has been, still. Simultaneously short (as always), and yet it's also felt so, so long. Now, at the end of week 12, the final video submissions for our at home challenges are due with only 5 working days left.


Like replacing a bent drive axle between elimination matches, this is coming down to the wire.

Red and Black


Robot coming together!


Whew, 11 weeks in the books. For us, we've been able to access our facilities for the past 3 weeks. Still 2 weeks to go.

<Queue suspenseful music track>

Will we finish in time?

Dun, dun dun...

The Shaft and the Shaft

Spoiler: Indexer, shooter, and gearboxes all ready to go!


After less than 2 weeks having limited on-site access, we have a rolling chassis that has already run some autonomous routines, some student-driven paths, and even collected a few power cells! (They immediately fell out, but, progress!)


In this next week, the goal is to finish manufacturing and assemble as much of the final systems that we can. This will give the most amount of time possible for practicing the skills challenges themselves.

Photo Dump(ster fire)

Really wish we could do choice color bumpers at competition...



Actually, not so much dumpster fire. It's been a good week for CyberKnights, the robot is coming along, machines are singing, parts are coming together, and at the end of the week - eh, no spoilers, read on!

(Ok, maybe the lead image is a spoiler, but it looks awesome, can you blame me?)

Boots on the Ground

The view from Discord looks a lot different!


Week 8 started off with a solid click. That click was the lab door being opened by our software team, spending their first day of the 2021 season in the lab, on site.


What a glorious day!

We're Done!



For the first time in CyberKnight history (and for a few mentors who have an even longer history,) the entire robot CAD is done before cutting a single part.

Also, we still have yet to cut a single part. Or step foot in the lab. Or even put the key in the lab door.

This is fine?

Obligatory Week 6 Post

You don't see this anymore...


This would be bag-and-tag week in an old, normal season.


Our major highlight of the week was the start of the full robot review. The burndown list was finished. Students took time to re-evaluate their systems, think about how to present, what questions to expect, and more. On Thursday, the whole engineering team took a top-down dive into our 2021 planned creation.

Setting Up Time

week 5

I imagine the school hallways look like this.


Something I've noticed, well, everywhere - work, robotics, family, etc during the pandemic, is that we no longer have "hallway conversations". Given we're remote, outside of immediate family we never encounter anyone in hallways, and this seems to make sense. But ad-hoc, spur of the moment meetings can be pretty defining. This year, we constantly have to make specific time to set up meeting time.


With the burndown list ever shortening and the CAD wrapping up, it was time to get mechanical, software, and electrical together to make sure everyone was once again on the same page. This is not our full robot review, but our controls, power, and sensor review. How does each system move, operate, what feedback does software have to control it.

Details, Details


Our master geometry got a little larger this week...


For CyberKnights, CAD usually starts during week 1, the chassis hopefully gets "approved" before the end of week 1, and then CAD continues on for a few weeks.


Many weeks.


Many many weeks.

Home Alone.... 365?

Still trying to remind myself what this place looked like.


Well, I'm sure you know what they say about the best laid plans and all... We won't be going back to campus for a while longer. This has the most impact on the Skills Challenge team - but almost every CyberKnight was looking forward to getting some actual face-time with one another. We'll need to wait a little bit longer.


To that end, this week will be more of the same. I need to try capture a few more OnShape screenshots to share... Put something other than text in these posts!



10,000 Hours


There's some quote out there about it taking 10,000 hours to master a particular skill or tool. Unfortunately - most people see fewer than 100 hours of that masterful skill being used. Some other folks are getting into F1, but I've followed the sport for years. You see the drivers mastering their vehicles for a few hours on a weekend. You don't see the hours at the gym, in the factory, the nutrition, studying the data sheets. Yet this is where and how the success is built.


In FRC we see some teams perennially at the top, and others trying to break into elite status. We see the robots and the matches. We don't usually get a good glimpse into the 10,000 hours of build season. Probably the hardest part of writing a process blog is finding and distilling significant stories within the combined hours of a build season. 


Pictured: Race winner following 2 hours on a Sunday afternoon.
Not pictured: Hundreds of hours in the simulator, the gym, the conference room.
Also not pictured: 2000 engineers, designers, marketers, etc...


For CyberKnights (trying to break into meme status - er - elite status) the Saturday and Sunday after crafting out an accelerated schedule flew by. With it, a blank sheet went to a solid baseline geometry for our 2021 Skills Challenge optimized robot. To be fair - having built a blue banner robot in 2020 gave us a significant starting advantage - our plan was to re-use as much as possible, simplify as much as possible, and finish the CAD as early as possible. With 10,000 hours from last year, and the hours from this weekend, we were well on our way.



All The Things! Part 2


Our leadership and scheduling conversations led to a very important discovery - We have a lot of tasks to keep track of this year.


Regular season award submissions including Chairmans and Woodie Flowers are pretty well known to us at this point. Somewhat new is a more organized version of the robot awards and submitted documentation. Each of the challenges then have their own components to capture, document, and make presentable. Our students are also grouped slightly differently - having both sub-team groups, and challenge groups. As things stand, we are tracking 5 individual groups of tasks: Core engineering, core business, and the 3 challenge teams. Each has their own space in Slack, Discord, and Google Drive, and each has representation in our weekly leadership calls for status updates. So far this seems to be working well - but we haven't started nearing specific deadlines. The real test of our organizational skills is yet to come.



The Tipping Point


Back in week 1, the tiger team (Frosted Flakes!) I worked with was looking into the Interstellar Accuracy Challenge. Our baseline was looking back to what our 2020 robot could achieve. For this challenge, the time limit didn't seem daunting, but the full range of distances looked daunting. Our 2020 shooter design utilized a single, high mass flywheel and a very stiff fixed-hood shooter. With software tuning, we were able to shoot reasonably well from 10-20 feet. Interstellar Accuracy Challenge has us shooting closer than this, and would also test our accuracy at the furthest range. These were identified as points to iterate on for our 2021 machine.


Easiest method to get the near distance was simply the raise the shooter. Fast forward to our current week and our weekend CADathon - our 2021 V1 design had a shooter several inches higher than 2020. To summarize the next Monday meeting:


"It looks tall"


After Monday we took another look at our core goals - Did a tall shooter meet our requirements? Had we defined our requirements thoroughly enough? Not quite back to the drawing board, but we did take a quick detour to prepare some Crayola CAD and attempt to put some numbers to our concerns.


It does look tall...


Pros:

  • Tall shooter should be able to accurately hit full range of distances more easily. - 2 challenges
  • We have some master geometry sketches already in place.


Cons:

  • High CG may impact speed and maneuverability. - 3 challenges
  • Crayola CAD showed CG higher than our ideal target.
  • We have last years complete master geometry with a short shooter.
  • When we moved the shooter up, we reduced the contact time with the flywheel - untested difference from our known product.


While the inevitable changes started happening, a small group (hooray!) broke off into another meeting and completely remade the schedule given the schools new guidelines. We built some additional contingencies into our schedule as well - if we are unable to get into the lab in 55 days (from the time of this writing), we're all rage-quitting. (It's on the schedule.)


The robot after Monday's chat.
Simple is good, right?


Random Musing of the Week


Write things down.


I hopped into the Innovation Challenge team chat today - they had a really good system where literally (like, actually literally) every time anyone said anything on topic and of interest to the discussion, it was immediately followed up with "write that down!"


This is important because, at some point this week, or earlier, I had a few random musings - things about FRC, things CyberKnights do, (things we should do) - and yet I can't recall any of them at this point in time! :-D


So...


How about this for a quick one: Game Design challenge teams, food for thought. Focus on the core mechanics. Make the core game loop amazing. The coolest little detail or specific little item is meaningless if the core game is not enjoyable to play (or watch). Come up with lots of ideas. Pick your best few core game loops/concepts (depending on team size), and develop them all. Playtest your ideas frequently as you make changes. You'll probably find that you're either falling out of love with a concept, or trying to hard to force the concept to work - at which point its time to fall out of love with the concept.


"So at the endgame there's going to be this cat..."
"Is it a fun cat?"












Have fun!

Puzzling Over the Pieces

I miss this place...
(It doesn't even look like this anymore...)

While reminiscing on previous build seasons, I've come to the conclusion that our lab leaks energy into people who spend time there. And now that we're away from the lab - we've been tired!


On the fortunate side, King's Schools - home of the CyberKnights - has made it possible for school teams to begin practicing in safe ways, and that includes robotics! While we have nothing planned, our current expectation is that groups of 5 (combined students and mentors) will be able to utilize the lab and resources for prototyping, manufacturing and building.

A Whole New World

This world had all of it's viruses eradicated...

It's going to be a strange year.

I feel like everyone is saying that. I also read it on the internet, which means it must be true.

Welcome to 2021, and the unofficial 4911 CyberKnights build season blog (from the view of a mentor who is still wearing pajamas). This will be a little different than years past, given the COVID-19 pandemic and changes in society, but the goal of these posts were to tell our story and provide a look into our process, so hopefully some things will be the same.
