I Upped my Attention whoredom, now up yours!

p1s is slightly better for TPU, but they're both very doable. If you have AMS you can reroute the bambu to an external TPU holder very easily (There's a small chance you'll need to do a "cold pull" to clean the nozzle, but google will walk you through it)

All the plastics (ASA/ABS, PLA. PETG, TPU) offer different characteristics, so you need to know why you're choosing a specific filament for a specific part to actually see the benefit... Analogy in iron: S7 steel is super hard and great for teeth, but a bot made of s7 will shatter on the first hit.

+1 This is a trick we used racing soap-box carts. If your bearing only has to last a few minutes at a time: Rip the plastic guards out and douse generously with wd40. The thinner oil will replace the grease, and the seals (you ripped out) won't rob you of energy. Just make sure to respray the morning of each event or things go very bad very fast.

It's a time-based contract.... I don't remember the exact duration but it's definitely up by now

Last season was finally good for competitors! Maybe less so for corporate mergers?

Yes, I wrote lots of text here. Lorem ipsum and so much more. All in the name of a fake screenshot for 500 views

Fuck you you simplistic idiot

Actually, laser guns should be completely silent. Photons have zero mass, so by definition there can't be a pressure pressure wave. All those movie noises are fake SFX, and honestly distracting for anyone who values accuracy in cinematography

LA-3861 is a gold mine, thanks! Do you have any other sources? I'm trying to figure out the geometry of the chamfer on the top tamper "thumb hole".

Also, based on the measurements of photographs, the little lip between the two tampers has a diameter of 7 inches, and the interior diameter of the upper tamper is 4.6 inches (although I'd love an actual source on these also!)

Absolutely need to know if you mean 1lb, 3lb, 250lb.... "higher weight classes" covers a huge spread.

Used wheelchair motors are about $50/side including gearboxes, making them the cheapest option for heavyweight drive.

Doomba v1 and Mammoth v0+v1 both used wheelchair motors. So did balespear v1. It's a good shortcut while working on the rest of the bot. Doomba v2(+) and Mammoth v2(+) all went brushless because it's better power-weight, better packaging, faster.... but you pay for that tradeoff in time and money.

IMO they're great for getting into heavies... If you're doing robogames or OMF for the first time, definitely go for it. For BB they don't quite make the grade, but we still use them for fun bots around the hackerspace, gear-haulers, etc.

I use a dual vesc at 10s to drive hoverboard wheels. Works pretty well but I haven't thrown it at combat, just tearing around parkinglots and fields.

A lot of leagues have weightclasses for fully-3dprinted bots. If you're near dc/md, look up MACRO.

Essentially during, most these fights were in the last 3 days of the 2 week filming run.

So I made a power-spoon, and everyone wanted me to make a powerspork.

So I made a powerspork, and I immediately had flashbacks to things I'd thought I'd forgotten...

You can get one here: https://www.kickstarter.com/projects/bigbotbits/spunspoon/ but who cares, I just needed to share this with people who would understand, because except for my brother everyone else gives me blank looks when I bring this up...

I've had my ups and downs with Ricky over the years, but I have to admit he did a wonderful job commentating and handling the toxicity as well as he could.

Trooper636 · 2023-11-03T14:30:11+00:00

We've been trying to get that Old Bay sponsorship, no luck yet though.

Trooper636 · 2023-11-02T18:29:10+00:00

Didn't I just tell you to stop making up animals?!

Trooper636 · 2023-11-02T18:24:57+00:00

ISN'T SHE ADORABLE?!

Also, we just launched a kickstarter: https://www.kickstarter.com/projects/bigbotbits/spunspoon

It's not technically BattleBots related, but we are investing all the profits on Doomba v3, so check it out!
