Absolutely deserved award. Any time a question is asked in this community there's a 50/50 shot you've answered already. You turned this sport from "how do I even start?" To "This is so fun!" for myself and lots of other builders.

[@JustCuzRobotics]

That means a lot, thank you!

[@bami2]

Congrats on the community outreach award, you deserve it 100x. Just looking at how many of your kits and parts are out there would be simply amazing, but your videos are incredibly helpful for anyone who wants to get (back) into the sport! Also that key bar on top of Subtraction hits so incredibly hard, just slicing through bots killing all the juicy parts inside is astonishing. 7:01 What I think happened is the recoil of Wormholes hit caused the bot to spin, the gyro from the weapon wanted to stabilize it vertically and once that hit the floor combined with one wheel still on the floor going backwards it transformed the energy of the weapon into a bunch of angular momentum that flipped the bot in the air spinning lengthwise towards your weapon and the back of Wormhole made contact with Subtractions weapon, probably introduced a lot of G forces in a particular direction on the PD board (I assume negative-Z, so with the components on top yanking the board down), the voltage regulator became detached and killed it. I'm not sure if that's an actual design flaw with the PD board (the forces involved are pretty insane) but you can probably prevent it like you suggested by potting some components onto the board instead of relying just on the solder joints.

[@The8BitNerd]

I think this is the first time I have seen a robot tap out to a robot with a lifter.

[@Julipapa]

Great video! Great showing by Subtraction! I'm glad I got to be a part of that crazy grudge match!

[@Julipapa]

I posted that before I even made it to the end lol Thanks for the shoutout. I'm glad that mangled battery made it in the video

[@amadensor]

We knew combat robotics because of Robot Wars. Recently, we went to Open Sauce. We saw NHRL, and saw the smaller classes. My wife said we should make some. I told her to find a local event, and we would. We found local 150g fights. I watch your videos to learn how to make better robots.

[@JustCuzRobotics]

That's great!

[@forceofwillgaming8475]

was mako using the triton blade from fingertech there. Oh my god

[@Julipapa]

It was for that match only! And it will eventually make a return with a better mounting method 😆

[@js_injection3978]

This was my first competition! It was a ton of fun!

[@eioclementi1355]

I'd love to join a hobby like this.

[@samuellondke9108]

The fool had such great sportsmanship from its match.

[@samuellondke9108]

Also good job with subtraction, it had way more improvements! Do you have any ideas about what you can do to solve the invertability or ability to self right to prevent what happened in the wormhole match?

[@Johnzobeams]

Was Division now subtraction Future square root

[@JustCuzRobotics]

Addition has already been designed...

[@lizrrdbreath]

ahhh congrats on the reward you super deserve it!!

[@JustCuzRobotics]

Thank you!

[@CREEMkitty7]

Can’t wait on addition and multiplication 😂😂😂

[@WartycoonDuos]

ssp chasis 10k iq

[@IronOre33]

Cool design proly idk i didnt watch da vid yet

[@JustCuzRobotics]

Thanks for sharing IDK I didn't read the comment yet

[@sickboy1031]

Hoping for a subtraction weapon system kit or full bot kit soon 🤞

[@XselfwillrunriotX]

I’m not a full blown engineer, but I’ve always been fascinated with making a bot, or at least attending an event. Seeing that you were just in Boston at this event is a huge arrrrrrrgh moment because I live in Boston and have been trying to see if there were any events coming up. Do you happen to know the events coming up in the Boston area for 2024?

[@JustCuzRobotics]

I'm hopeful this one will return but no dates yet

[@XselfwillrunriotX]

@@JustCuzRobotics maybe one day I’ll catch you over there and give you a run for your money against one of your own kits! 👊🤣 Good stuff my dood. I’ll keep an eye on this little beast. 🤘

[@stefanrabicano2327]

When will the speed controllers be back in stock? Been waiting to make my big purchase until i can buy everything at once.

[@JustCuzRobotics]

Around the 19th

[@connorbingel7134]

How big are your overhead blades? I wonder if the motor would need as much shock mounting for a smaller weapon, say 120mm in a vert? Sell these damn things already so I can buy one

[@connorbingel7134]

Ahh. Didn’t watch all the way through before posting that but thought to check the description. They are for sale. Love you seth

[@JustCuzRobotics]

The blue blade in this video has an effective 10 inch diameter about 254mm

[@paulhurd954]

Are you selling subtraction kits? With the overhead spinner I mean.

[@JustCuzRobotics]

I am not currently but there's a decent chance I'll offer the weapon attachment as a separate add-on purchase. I still think the SSP kit is the best way for new Builders to start and that spinning weapons are too dangerous for brand new builders so I'd prefer that everyone purchased the SSP to begin with

[@paulhurd954]

@@JustCuzRobotics I have built spinners on an Ant weight scale but not had the time to upscale and research into which motors etc to use at beetle weight. Would you be open to a private sale?

[@JustCuzRobotics]

I still want to spend more time trying to figure out how to make the robot either drive upside down or self right before I'm comfortable selling this add-on. But maybe in a few weeks. Right now my main focus is on the January 20th event

[@KodyFurlong]

They need to paint their floor.

[@JustCuzRobotics]

Hopefully they have time to do that for the next event, the arena was borrowed from NHRL and they didn't get a floor included I think

[@marko4480]

Im waiting to see aluminium frame for ssp and how it does

[@JustCuzRobotics]

Aluminum is 3X as dense as the UHMW it uses now so it would require a complete redesign

[@marko4480]

Is it worth trying to make it? Would it be too heavy ?@@JustCuzRobotics

[@JustCuzRobotics]

It would be way too heavy without extensive design modifications

[@Saidizt]

Thx for the Video but i dont make Robots .....i looking it for Fun in Germany

[@andrewpetrov7646]

still cant get over that hit on 15:08

[@Julipapa]

For the record, that was not an extra hit. The tapout was called as soon as I tapped. I was thinking about letting Subtraction smack Mako around a bit more, but one of my drive sides was locked up and I didn't want to take extra damage to the juicy bits

[@Kurse_of_Kall]

@@Julipapa Very entertaining fight, thanks for doing it! That weapon collision at 15:00 was awesome!

[@JustCuzRobotics]

Also somehow your battery had been damaged for like 75% of the fight? I still do not understand what was going on with that working

[@JustCuzRobotics]

Same here!
