That design is amazing! The amount of engineering is insane in all your builds! Keep it up and I look forward to seeing more of your videos! Also another thing as well with your flipping problem, yes absolutely the ring is too close to the ground. Also a few other things that I have also encountered as well that might help. Here's a theory I have for your bot, I think because your ring is all MOI so their is a ton of gyro when turning or moving around, so the thing is your system depends on your main motor constantly driving the ring because its all geared. Meaning their is no room for your motor or ring to just coast because theirs too much friction with the gears. So when you go off the throttle or turn (Turning with your weapon on also decreases speed) it immediately slows down too fast and throws you everywhere. That's why on vector I use smooth pulleys as it allows the main weapon to slip when coasting negating this problem(Along with main weapon motor longevity). Best way to test this is to try and spin the ring (With just your hand and the bot powered off) and if it immediately comes to a stop after you let go or after a second or two, it may have to much friction. Hopefully this helps!
Thanks! I think I may be able to attempt to tune the weapon deacceleration through the ESC firmware. Im trying to juggle between gyro and manueverability and I do want to to be able to deaccelerate quickly believe it or not. One of acro's main features (not that functional this time) is that it's supposed to be able to make large leaps into the air through fast braking the ring. I do think you are correct in that my weapon may not be free spinning enough and that is something I have to look into since my tolerances were probably a bit too close for a few parts. I may try a friction driven method as well or something different completely but we will see. This was really insightful and I truly do appreciate some pointers ❤
@@PotatoCream Friction drive would also let you get rid of the gear teeth, which are a massive stress riser when getting hit by horizontals (or anything else, horizontals are just a worse case for this sort of impact). Impacts will be the biggest issue with any ring-drive system as it's way harder to impact-proof the bearing system seeing as it has to be rigid to hold the ring properly. Shock mounting the whole weapon system from the chassis might help, but that'll come with it's own issues with that much mass/inertia trying to manoeuvre at speed. Cool design, hope it does well in future!
@@k1ll3rvc Yes, some great pointers and I think it will only get more difficult if I aim for higher weight brackets. I might be able to still get away with gearing for 3lb but I definitely am planning on testing a friction driven system as well to gauge performance.
I would love to see more of this robot. I would imagine you have already started working on a wheelie bar to keep the robot stable. I would also like to see some of the design and science that went into making this incredibly creative robot
Thanks! Meeting you and your bot really helped make it clear of some errors in my overall design (namely repairability). I hope we can meet again in the future as well!
I enjoyed looking at your design in the pits. ER Stingray 2 team. You might try a 4 wheel (two motor) upgrade f or stability. There is software to slow your weapon while doing non combat turning-then go full power just before contact.
Oh thanks for letting me know! I did lower my audio but I wasn't sure if UA-cam did any audio normalization. I'll try to make adjustments in the future.
I watched this in the livestream and loved the concept! Shame it couldn't go further. I wonder if Deep Six style stabiliser bars would help get the balance you're after?
I think there's a few things I want to try but first I need to increase my ground clearance for the weapon to see if that was the main cause of my issues.
Your faital flaw is "NO WHEELY BARS ON THE BACK". No you know and knowing is half the battle! Your second big flaw is you need to make your weapon wheel completly out of meatal. and smaller. Maybe make the teeth a little lnger.
When I saw an ACRO signed up for September I got so excited, then resigned that it probably wasn't a beetlweight version of your plant. Very glad it was.
Thank you for the kind words about Frostbite. ACRO is one of the coolest bots we've ever faced and we can't wait to see your improvements!
It was an awesome fight! Seeing steel getting shattered rather than bent was not a failure mode I expected. Frostbite is a real formidable opponent!
this is a really cool design and i really hope that you can make this work as this design could be revolutionary
I see what you did there.
That circle transition was such a good idea!
❤
This is by far one of the coolest designs I've seen in a while!
Such a cool design that instantly grabbed my attention watching the prelims. Will definitely be rooting for it in the future

Only got to talk to you briefly but it was great meeting you! Also “win 2 and qualify for December championships”, I wish that was the case 😭
I had it noted in the description. My smooth brain at that time did not read it correct 💀

SUPER slick video- great work and I hope to see more!💛💛💛
holy cow, this is such a cool robot. Good luck at nhrl in the future
This is super. Really excited to see the next evolution!
I might be a little late here. I wish you can get the design working in the big leagues, it is so cool!
Bobby Mcafee sends his love.
Thank you! ♥
Acro is genuinely the most beautiful bot that I have ever seen
Thank you!
your weapon keeps making you flip over
I’m Pablo, the guy who sat across from you at the pits with Kasper. It was cool meeting you, good luck in your future competitions!

That sounds interesting, I'll look into it!
I would LOVE to see you build a 3lb Wayward for the next NHRL!
Probably not for 3lb as of now but I think if time permits who know? 🤞
Nice video. Seemed a bit quiet though. The robot looks a fair handful with the gyroscopic effects playing havoc with the handling.

Maybe the ring idea would work better as a horizontal spinner
I think it would be hard to constrain it properly and you're better off running a shell spinner at that point for better constraints of the "ring"
Your faital flaw is "NO WHEELY BARS ON THE BACK". No you know and knowing is half the battle! Your second big flaw is you need to make your weapon wheel completly out of meatal. and smaller. Maybe make the teeth a little lnger.

At one point I did consider bringing in the 1lb version as a minibot!
Very cool robot.
Thank you! I wish I got to see you and Pepe Silvia!
It's a very nice looking bot. Needs some revision though!
I agree!
Needs a wheelie bar.... Or a flywheel
I like your thinking, but the only correct answer is a bigger weapon ring. I'll definitely consider it if it becomes problematic in the next iteration
TRULY INSPIRING POTATOCREAM bleh bleh bleh
THANKS!
So you have built some 1 pound plastic ant weight before right
Are you allowed to use tpu for tires?
TPU tires are allowed. At least for the competitions we've ran, wheels are exempt from material restrictions.
@@PotatoCream ok thank you 😊
NHRL has some of the coolest bots, Acro will be right at home there one day!
What was the second bot?
"Xanadu," a dual disk vertical spinner
Cool but awful design.
More time spent flipping itself over than anything else.
It was in fact a bit of an upset but just I'll make it work once I fix the kinks! 🤞
