logikv9 posted:i saw hydra smoking a bit early in that match but then i remembered the factoid about having an oil filter now so for some stupid reason i thought it was simply exhaust Yo, sorry to bring this up from a week ago, but let's talk about metallurgy Steel can be hard, or it can be tough, depending on alloy and heat treatment. Hardness is like a diamond - real strong, but you can smash it up with a hammer. It's very brittle. Toughness is more like what you might see if a car hits a lamppost. The lamppost will bend, but it'll stay in one piece. If you hit it only a little bit, it might deform slightly (like, the top of it might be visibly wobbling) and then spring back. What do you want Tombstone's solid bar to be like? Well, if you anneal it to be really tough, then it'll spin around and will never truly break, but it'll be like silly putty. It'll hit another (hardened) bot, and the bar itself will be all gummy and have chunks of it mash to the side and not really do any damage. If you temper it to be really hard, that's even worse - The whole thing will shatter. This actually happened a few seasons ago, Tombstone's bar split in half. To be the best of both worlds, you want both - An annealed soft bar in the middle, with a hardened business end to gently caress up bot armour. There are two ways to achieve this: You can build a single bar, and harden only the end using some fancy heat treatment process. On something that large and heavy, this is incredibly difficult and expensive. If a bar tip gets slightly hosed up, you also can't really recondition it. You have to toss it and put a new one on. It is also hard to check to see if you've done it right. The other method is to use a soft bar and put hardened inserts on the end. This is what they've done this season, and there are a lot of benefits. The bar is cheap and easy to make, the tips are cheap and easy to make, and there isn't a lot that can go wrong on the build side. It's easy to check that each part is hard/soft as appropriate, and if the tip gets damaged, you just bolt a new one on. This is a similar strategy that professional machinists have been using forever for lathes or mills - They have cheap toolholder and bolt on tiny little disposable carbide inserts on the cutting side. Obviously the issue here is that they didn't bolt the inserts on well enough. So it's a design problem, but not the one you think it is.

Great Beer posted:Tombstones been bolting teeth on to the bar for as long as it's existed. Before laser cutting got so cheap it was pretty common and it's generally worked out. Except for that one time with Nightmare. Yeah, checking, it looks like they have both varieties. They lost their bar in S4 vs. Bite Force, and it was the solid tool steel bar. Makes sense. They've also chipped a tooth a few times. In short, mechanical engineering is a land of contrasts

You'll see a lot of smaller weight divisions that there are 5-6 common kits floating around. Someone pays $600 and assembles it and slaps a unique paintjob on it and competes. I get it if you're just there to see how the competition works for the first time, but a few of them have been running for several years, which seems extremely lame to me.

Skorpios is good at driving, Sawblaze is good at punching holes in armour. Probably one of the best at targeted armour holes, actually. I also like the Skorpios team although I was surprised and horrified that the captain/driver Zack guy is younger than me (he's like, 32)

A problem with many bots with huge spinners is that they take a long time to spin up. A well driven and really aggressive bot can stay on them and keep them from ever really getting up to speed. A cool design feature of Switchback, if it actually worked (it doesn't) is that they can keep the spinner away from the action until it's at speed, then drop it back into the fray. I feel like that must have been the intention of Tantrum, but they don't seem to talk about it, and it's so small and buried deep that it seems ineffective.

He's got a good series on building the various incarnations of Overhaul here and other places around his site: https://www.etotheipiplusone.net/?cat=123 He's posted some frustration at how boring horizontal and vertical spinners are, and I believe him that he has no desire to join all the other teams in converging on almost exactly the same design. I guess that's part of what Battlebots is trying to do with mixing things up with the upperdeck, but it really is a challenging problem, trying to encourage more innovation. Like, Smee and Huge, and probably Hydra don't really have a chance of ever winning. The latter two are hyped up a lot in commentary, but their reputation hasn't really been particularly lived up to ante fucked around with this message at 09:14 on Feb 27, 2022 |

I'm excited to see how they do, they're the most interesting new concept to be developed in a while. They talked about why they wheelie in one of their YouTube videos. Basically they have a huge flywheel internally, oriented kinda like where a steering wheel would be. The gyroscopic forces don't like moving in that direction when Blip moves forward, so the resistance causes it to pop a wheelie. I don't know what it looks inside, but a future redesign could orient the flywheel like a horizontal spinner. That would allow free movement in any of the directions you want free movement in - forward, back, and side to side - but would prevent changes in really good ways, too. It would be nearly impossible to flip, and world always remain planted on the floor. It could be incredible, if they could make it fit.

Yeah, I saw that, but they go through it very quickly. They'd definitely have to build it from the ground up with a horizontal flywheel as a design goal from the beginning, I'm not suggesting it would be easy. Or even possible. Very powerful though

Rotator sucks imo Tantrum is also kinda boring but I like their team Neither of them hit hard Also agreeing that End Game is a boring cookie cutter bot, but their driving is pretty incredible - All of their fights this season, as soon as their opponents get offbalance, they've managed to end it. Absolutely no mistakes.

Okay, calling it now. There's a hosed up judge's decision relating to Cobalt. The last one was hosed up, but can you even imagine if that was the finals match Edit: actually I'm going to go one further. Exhibit A: someone said that the Cobalt match is important for future context Exhibit B: Aren has never hinted at any drama, and as far as I've seen, no one has directed any at him. So I don't think he has anything to do with it Exhibit C: Hydra has been posting judge scorecards and complaining all season Conclusion: there's a questionable decision in favour of Cobalt vs Hydra. As much as I like Blip, sounds like both those bots are out ante fucked around with this message at 19:04 on Apr 4, 2022 |

I think I mentioned this right at the beginning, but Tantrum's design in theory is super cool: They can hide the blade until it spins up and then reveal it only when it's at max efficacy. Other spinner often get blocked from spinning up during pins. In practice, it just never works very well though. They just have the shittiest spinner of the entire competition. Would definitely have preferred Blip winning, a flipper getting nutted would have been a huge upset.

Tip speed is capped at 250mph, which is a super strange way to do it, because that doesn't specify the actual energies. I hear it's an insurance requirement for the poly carb arena walls. There was that insane chain bot a couple years ago (hella?) that got DQed last minute for being too insane, but the exact reasons seemed nebulous and arbitrary
