[@BrianThornber]

Thanks for the grudge match Seth! As soon as I got home I figured out I was high centered on my bottom armor plate (I had done all my at home driving without the bot fully assembled ). Hoping to bring a mobile version of The Reaper to August's NHRL!

[@JustCuzRobotics]

Looking forward to seeing a working version of The Reaper!

[@NoRecord-eu5ib]

I don't know if i should be happy or scared that I'm also going to be there

[@pauldoe3201]

Damn that intro went hard 🤘

[@Falinzin]

Lets go! Metal subtraction!

[@Kinekitsu]

Wooooo~! Subtract the Competitionnnn 🤘😈😈😈🔥 (Love love the bg music and set too~!)

[@JustCuzRobotics]

Thank you! I'm glad someone took notice lol. I just started a 7 day trial from Epidemic Sound and grabbed music from there, they have good stuff. It's really really hard to find royalty free rock and metal that doesn't sound like complete trash, synthesized guitar is just super bad most of the time.

[@Kinekitsu]

@@JustCuzRobotics As someone who loves guitar, and also struggled to find good BGM for like a full day on thier last vid, totally get it!! I’ve heard of Epidemic, might have to look into them now! All metal Subtraction kicks major ass and I 💛 your vids~!

[@IronOre33]

Is there a “multiplication”? I mean you got division and subtraction so why not multiplication?

[@JustCuzRobotics]

Not yet, I'm saving that name for maybe a larger weight class than 3lbs. I did work on a plastic ant called Addition but it caught fire before it was able to compete.... I'll have to give it another shot someday.

[@IronOre33]

@@JustCuzRobotics when you make multiplication you should some crazy thing to it, i feel like division and subtraction are too bland or generic, i know they perform really well but they look like most combat robots, if you add something different and experiment maybe you’ll make a very powerful robot, just an opinion though

[@JustCuzRobotics]

Both Division V4 and Subtraction have something weird and experimental... Both use direct drive weapon motor systems which is extremely rare for the 3lb weight class, billet aluminum is extremely unusual for Subtraction and a counter gyro flywheel is about as weird and experimental as it gets on Division V4 lol

[@IronOre33]

@@JustCuzRobotics oh, im a beginner so that seems normal, do you plan to add something weird to multiplication then?

[@DigitalJedi]

Multiplication sounds like the perfect name for a multi-bot. IIRC the NHRL rules would allow 2 20lb bots to enter the 30lb bracket.

[@Battlebotboysyt]

I could write an essay about how much I love this robot and this video. Great job!

[@JustCuzRobotics]

Aw thank you!

[@Lusidous]

I love seeing all the new bots you keep making, but when is mini mulcher going to get some love?

[@Julipapa]

Great video as always I'm excited to see how Subtraction does at Teams!

[@Julipapa]

And I love that you left in the little clip with the kid at the end of the grudge

[@The8BitNerd]

It would be awesome to see more driver cam footage, and it also seems like the perfect candidate for being easily turned into shorts footage if you were ever interested in doing that.

[@JustCuzRobotics]

I already have used it for a few shorts. They don't often get many views tho

[@The8BitNerd]

@@JustCuzRobotics That’s kinda strange, since shorts typically get pushed in the algorithm more initially than full videos.

[@JustCuzRobotics]

That is sortof true. I have found most of the time when I post a short it gets a lot of views within the first few hours, and then almost completely flatlines in views for weeks to come. My long videos get a chunk of views (usually between 1000 and 2000) in the first 3 days, and usually at least 1000 more in the next 2 weeks, and a slow and steady trickle of views for years to come.

[@TeamJunkYardDog]

We have to get to the NHRL soon! Great recap!

[@JustCuzRobotics]

You should!

[@Gunstick]

I love the traffic cone style!

[@ozan1234561]

He should really put reflective tape and a square base on it to make it look like a traffic cone

[@JustCuzRobotics]

It"ll be hard to make that stick, the cone spins at 12000rpm

[@gregbush8573]

please start referring to the cone as the "Wizard's Hat" that is all ;) also imagine bringing an SSP and your opponent is not only another SSP, not only the maker of the SSP, but also a full metal SSP bot O.O

[@user-zh2lh4iz8j]

0:55 ‘and on the third subtraction video seth rose’ the battlle bots bibl

[@TheInvertedFollicle507]

Great video though I'm surprised you didn't get at least frowned upon by KZbin considering their copyright guidelines are notorious for generally being pretty strict.

[@JustCuzRobotics]

The copyright guidelines? For what the music? I am licensing it with a paid membership to Epidemic Sound

[@TheInvertedFollicle507]

@@JustCuzRoboticsyeah the music and OK that would explain it.

[@zenithparsec]

Billet Metal Chassis - Good for 3lb Combat Robots? I hope it's good enough. my first bot uses it.

[@gearheadmetalfactory6402]

Will the new updated chassis be available on grab cad? The latest chassis version of subtraction has come along very well.

[@JustCuzRobotics]

That depends on if it actually works in combat

[@gearheadmetalfactory6402]

@@JustCuzRoboticshow did the aluminum frame held up during the competition?

[@JustCuzRobotics]

The V3 chassis hasn't competed yet, it will be fighting June 1st only. I never got my CNC Madness order in time for Bot Brawl so I ran SSP

[@gearheadmetalfactory6402]

@@JustCuzRoboticssubtraction has definitely come along way from the beginning. The new chassis design does look amazing and I hope everything goes well during competition.

[@starry53]

Overall, Subtraction 2.0 is a decent bot in March NHRL. Looking forward to see the Version 3.0 of Subtraction, when that video comes.

[@Caliver_174]

Why do you have a backplate of saw blaze?

[@JustCuzRobotics]

Ebay and because Sawblaze is cool

[@Caliver_174]

@@JustCuzRobotics oh ok

[@PinkSalmon]

What happened to ShrapnelMine? Is the project over?

[@JustCuzRobotics]

Not over forever, it's been on a very long break. That bot was really complicated to design and didn't work very well so I need to go back to the drawing board for it to do the concept justice. The first version took me more than 6 months to design and prototype into a working form - I do not have that kind of free time these days as I am running a business full time now. But I do want to bring it back!

crap wiring over your right shoulder is not a good look...........................
