/diy/ - Do It Yourself

>>1026897
WHO /ICEWAVE/

But seriously, I love this show.

>>1026897
4chan entry for season 3?

>using the ABC logo instead of the Battlebots logo

Eww

>>1027044
I still wonder why ABC had to make the new logo such shit..

>>1027045
gotta create jerbs for young shitty graphics design majors

>>1027041
Would anyone actually be interested in throwing together a team entry? I've fooled around with the 30 lb and under bots for the past seven years and would be up for a strange 4chan collaboration entry.

>>1027238
oh shit

riobotz is that you

Not at all, I'm just posting random battlebots pictures I have to keep the thread full of shiny metal objects.

Reminder that girls suck at this sport.

Reminder that Robot Wars is on tonight on BBC 2
You can watch it on BBCs Iplayer website if you have a VPN with a UK server. (though they may have banned big name vpns)

Sure its shittier than Battlebots, but do you really have anything else to do tonight?

>>1027440
Or just go here.

>>1027440
>Sure its shittier than Battlebots
Is it?

These new seasons of Battlebots are pathetic. The Pulverizer is a joke, and the bots mostly suck.

>>1027481
>complaining about the pulverizer

Leave it to a Robot Wars fan to complain that the gimmicks arent gimmicky enough for him

>the bots mostly suck.

I find this highly ironic, seeing how Robot Wars always had the worst, most ineffective bots that would have never been allowed into other competitions.

Cant wait to watch the return of axe bots and thwackbots on Robot Wars!
Gabriel is gonna be a crowd pleaser!

>>1027238
>fooled around with the 30lb and under

We probably know each other then. You in PA/NJ?

>>1027557
I'm from PA. Here is a video of one of my bots actually working. Which also probably gives away who I am.
https://www.youtube.com/watch?v=QGQ5rE5_YSg

>>1027561
That looks pretty fun

Im guessing that 30 pound bots are still pretty expensive to make?

>>1027563
That ones a 15 and price wise they aren't too bad.
Basic cost break down for 15 in video
>Weapon motor-60
>Weapon esc-20
>Drive escs-30
>Drive motors -36
>Gearboxes-80
>U channel for 2.5 frames-100ish
>All the miscellaneous goddamned hardware I never thought would cost much-120-200
>Blades-60 bucks for 3 blades worth of steel
>Batteries-100ish for 2 sets

This all is the cost for just the raw material with me machining everything and getting a friend to heat treat the blades for free.

>>1027566
Also worth note before building the robot I already owned the gearboxes, escs, and batteries. Plus the cost for the mechanical portion is for enough to make about 2.5 frames.

>>1027435
>shitty tombstone clone loosing against radioactive with armor made of cardboard
The only sad thing is that the bot didn't went up against something that would've left tiny bits.

>>1027440
Shit I missed it
Did anyone see it? How did it go?

>>1027622
and then it got demolished by the real tombstone

>>1027435
shitty tombstone ripoff is shitty

>>1027624
Was alright.
Its nice to have a full hour of show without commercials, nice to have filming in the pit. Too bad the pit filming and the announcers were kinda dull in front of the camera.

I think they edited the fights up worse than battlebots did. Instant replay, obvious fake bot sounds, way worse pumped in crowd noise.

I dont like the fact that 4 bots get eliminated without actually getting a 1 on 1 match, and I dont really like the round robin style tournament. Had to watch a shitty bot fight multiple battles because he lucked in. But things will get pretty good once the final single elimination bracket comes out.

I dont really like the pit, and I dont like house bots doing tangible damage to the contestants. One of these matches, a housebot is going to disable a bot, and that is horse shit.
Other than that it was a pretty enjoyable show

>>1026897
It's kind of a joke to me, really. I'll watch it, but I fast-forward through the talk-talk-talk, I don't care about their backgrounds or whatever shit they have to say, I just want to see mechanical carnage.

I remember the original 'Battlebots' that was on, what TLC or Discovery Channel? I forget now.. nothing much has changed since then, design-wise. There are a handful of proven designs, and those always win. On THIS show, they upped the ante a little, by having some flying contraptions (which never do shit) and allowing things like fire (which also really doesn't do shit, either). There are always dumbshits with fancy-ass looking contraptions, that go up against the more conventional, proven designs, and get systematically dismanted in a matter of seconds. There's only been one or two instances where my predictions on outcome were wrong, and they were because someone either had better tactical sense than the other guy, or someone cheaped out on their vehicle and got the crap kicked out it for their trouble.

Really it comes down to heavy-spinny-thing 'bots, and flipper-bots (of various kinds). Both are hard to beat. Of course this last week there was some fool with a nice, heavy-duty spinny-thing weapon.. mounted on a base that was WAY TOO FUCKING LIGHT, and as soon as it was up to speed and made a first attack, it LITERALLY went flying across the room. Dumbass.

You want to make an unstoppable 'bot for something like this? Heavy, hardened, high-speed, well-supported spinning weapon, mounted on a nice, thick, heavy base, with hidden wheels, and nice thick armor on the sides. It's like a Viking berzerker warrior with a battleaxe; you get that thing up to speed before anyone can get inside your weapons range, and it's a foregone conclusion that anyone coming near enough is going to get torn to pieces.

Of course that's too boring for network television, so they'd probably reject your application.

>>1027792
That was chromefly vs bronco. I guess another problem was that the spinning blades were mounted directly to the motors and fixed only on one side. Also why you'd use two light ones instead of one heavy is besides me.

Also you could wee that the blades broke on the points where they made holes in them to lower the weight.

>>1027803
nevermind, the blades were fixed on both sides. But the upper bearing really was almost worthless

>>1027792
>Heavy, hardened, high-speed, well-supported spinning weapon, mounted on a nice, thick, heavy base, with hidden wheels, and nice thick armor on the sides. It's like a Viking berzerker warrior with a battleaxe; you get that thing up to speed before anyone can get inside your weapons range, and it's a foregone conclusion that anyone coming near enough is going to get torn to pieces.
So a typical drum spinner then?

>>1027803
The true silly part was directly mounting to motors. Robots such as Last Rites break similar E Tek style motors despite theirs weapon being chain driven, there was no way in hell that one would survive a direct mount.

>>1027485
Literally what I was going to say. Fuck the gimmicks its about your bot's weapon. And the goats of robot wars were a deli slicer and a big pair of tweezers who just pushed people into a hole, they needed gimmicks and other robots to finish fights.

>>1027435
lol i didn't think it was possible to lose to radioactive

i'm pretty sure you could give me a pair of oven mitts and i'd beat radioactive. and i'm not a big guy

>>1027792
complete control got out-driven

warhead is a hilariously unreliable bot but CC got out-maneuvered for a couple seconds, warhead got a hit that damaged CC's drivetrain and the rest of the fight was a formality from there.

I also mute between fights.

>>1028013
Sweet Revenge was created by a group of high school girls, and it had technical problems.

Im surprised they didnt push it through this season

>>1028181
I dont understand how one of your most important parts can fail before the match even starts without anyone taking notice. I mean shouldn't they have standar d procedures to check their bot and make sure it enters the fight functional?

I was cleaning out my toy chest at my parents house and I found this. It must be a sign. My boy Bronco must win. His ancestors are counting on him.

>>1028442
You arent wrong, but that Bucktooth Burl bot was DOA this season too.

Not sure how they even get into the ring instead of forfeiting

>>1027624
>brought Razer back, only for it to drive itself into the pit first match
>commentator wasn't Craig Charles
>had a wacky underdog team you were supposed to root for but they were cringey as fuck on camera, literally wore fedoras, and their robot was straight-up shit
>in fact all the robots were some mix of unremarkable and shit
>commentator wasn't Craig Charles

Hopefully episode 2 will be better

most here have most likely already seen it, but this is really interesting:
http://www.riobotz.com.br/riobotz_combot_tutorial.pdf

>>1028654
Wait, its actually real?
I thought they were just making a joke on the broadcast.

Looks intense

the TV show isnt DIY doesnt this shit belong on /tv/

>>1028674
>>>/qa/

go cry elsewhere

i got a question. Is there any advantage to a drive system like pic related from ringmaster? It seems completly useless to me. It can't spin, it can't drive forward as good as four paralell wheels in a square.

>>1028847
In theory the builder said it was supposed to be maneuverable enough and I think that layout helped space wise for the bot but at the event it drove fairly bad.

>>1028847
It's holonomic which means it has as many controllable degrees of freedom as it has degrees of freedom. Consider a car: it can go forward, backwards and turn up to some degree, it's turn radius is bigger in forward than in reverse. A car cannot move sideways This robot can move in any direction with equal ease, it does not need to turn.

>>1027792
>what is weight limit

EPISODE TONIGHT

>>1029595
I think Pacific timezone is not gonna be able to see the match tonight

>>1029600
Just watch this
http://nowwatchtvlive.co/abc-live-stream-watch-abc-channel-online/

>>1027440
>>1027481
I remember robot wars having events other than just "smash the other guy's robot" though. Those were cool.

A hammer KO what an event to witness.

>>1029638
When you build your bot to go through the gauntlet, and to last a whole round robin tournament, you build it different than a combat bot.
So when it comes time to go combat, you are underwhelming

theyre gonna give megatento the decision. weapons over driving and control this season for judges.

>>1029653
Its because the judges are NFL players who dont know what they should be looking for

shieet i was hoping stinger would go all the way

that highlight from bombshell was really clever though, hopefully the full thing gets posted soon

>>1029659
it's actually the crappy ruling system this year, producers probably wanted to avoid something like biteforce's measured, calculated-but-boring trek to the top last year

>tfw raked

Is the torrent up yet

>>1029750
>tfw chomped.
>>1029798
where do you torrent from?

>>1029749
I'm mad, I'm double mad from last night's episode

>>1029830
Me too. I wonder who the judges were, if they were all celebrities or they had someone who knew a bit about how the match went rather than the flashyness of a lost wheel.

>>1029832
Jessica Chobot - video game tv presenter from G4
Vernon fucking Davis - middling former 49ers TE who won a superbowl by sitting on the bench on a 1 year pickup and is currently on the god forsaken redskins
Third guy was the long haired guy, dont remember who he actually was

>>1028017
Warhead got so lucky puncturing cc's gas line and igniting its own flamethrower at the same time.

>>1029829
Torrentz or thepiratebay.se

>>1029833
>>1029832
adam savge was a perfect judge, he has literally built and battled bots in the past. Its where he found the chink from his show. Why cant he just judge the whole thing.

>>1030122
Took me a while to figure out what you meant; but I thought he met grant elsewhere working on film props.

I'm upset about the lost wheel and the value the judges gave it. When you consider sewer snake is designed to able to lose many of it's wheels without much impact to it's drive. A lightly scuffed harbour freight wheel isn't much loss compared to a melted pool and control of the match.

>>1030132
They also didn't count stinger's attacks with primary weapon and pins, which is what should have happened if the decision went to the judges.

what a disappointment. the megatento decision was a fucking joke and i was hoping that chomp would finally get stomped out. At least bombshell vs cobalt was interesting.

Wonder what'll happen with bombshell vs red devil next round.

>>1030302
I know what will happen. One of two awful bots will get further in the competition

>>1030319
i hope yeti will rip megatento to shreds. Why do all of the powerful spinners have to be in other brackets?

>>1030302
bombshell vs. RD looks to be one of the few fights next round that aren't stomps

look forward to seeing two well-engineered, technical machines going at each other

>>1027566
The total sum is 666

>>1030589
That is how the true pact to build a hobby weight is formed

this foxic and speed squared batle...

Battlebots is pretty fucking gay because the only interesting bots are the ones that are impractical and get beaten by something that just has a wedge or flips you.

>>1030984
This is robot combat
If you want gimmicky robots that arent built to take and deal damage, watch something else

>>1030996

If I wanted to watch squares attack each other I'd throw a limited edition comic in a room of nerds.

>>1031002
>trying to bait with comic book jokes on the most normie board filled with rednecks who work trades
>in a thread about glorified RC cars, with contestants like plumbers and welders actually making the bots

Im sure you could put a little more effort into that

>>1030302
i don't mind megatento as a robot. i think it was a close fight since stinger's flame seemed pretty ineffective and it couldn't lift megatento. i though it was a coinflip and that you shouldn't judge the missing wheel because it isn't a stinger/sewer snake fight without lost wheels.

and i was pissed about chomp vs disco inferno but this was a legit win for them.

>>1031002
>>1031014
Witty anon has a point
It'd be neat to see something like gladiator pairings develop, for variety

>>1031979
this board is slow as fuck, we were on page 5 or so

>>1032003
weird, I could swore I saw page 8 or 9.

For brushless setups I prefer voodoo, black magic and throwing the largest brushless dong at it I can.

Is it legal to mount angle grinders on the robots?

>>1032976
If its DC definitely. Only thing that might not allow it is if its AC and you try doiing dc to ac shenanigans .

>>1032979
Onto my next question then.
Has anybody ever mounted one to a robot?
It could make quick work of pretty much anything they throw at it.

>>1032980
unworkable. you can't grapple a big league opponent long enough for a grinder to make a killing cut. you'd throw a few sparks and get punted into the ceiling.

>>1033054
>red devil vs. witch doctor
A saw doesnt really cut faster than an angle grinder i think

>>1032980
Yes, one robot with a HF drill as its main weapn had an angle grinder as its backup one

>>1033274
>http://battlebots.com/robot/road-rash/
two abrasive wheels being backed up by two smaller diameter carbide tip saws, driven with two chains. and the grappling arms are FAST. it's good!

but the weapon arm has a fixed attack height because of that four bar linkage, and it looks like there's no self-righting function. is the 'bot able to weeble itself upright somehow?

What are your thoughts on Hellachopper?
Should they have been allowed to compete?

>>1033423
I have no idea, and in all likelihood, the world will never know.

>>1033621
Rob Everhart sought out to make the most dangerous machine ever to enter the Battlebox, and he certainly succeeded. However, since he's from the old school, he never gained a proper appreciation for high-rpm high-MOI weapons, modern speed controllers and motors, and most significantly, LiPo batteries. I saw him several times in the pits removing LiPos from his frame and arcing the leads off of each other while he did it, which on these high voltage, high discharge packs is a great way to fuck all sorts of shit up.

I would have loved to have seen it fight, but Trey still has some leftover paranoia from Season 5 when Nightmare threw someone out of the roof and Lockjaw and Vladiator knocked out some of the walls. There's a big crisis going on it the community right now with respect to arena breaches, and the last thing Trey and Greg want is ANOTHER lawsuit.

So yeah, I think they were right to get passed over from a safety standpoint, but I would have rather seen it fight. From the safety of the next building over.

>>1033717
The arms he put on that thing don't really look like the could take a hard impact either...

Is there any reason at all to not go for a bar but something with three or four edges?

>>1033717
How the fuck did he get it moving so fast?

>>1033813
those arms were on pivots, like a flail mower.
compared to a solid bar there's less impact transmitted back to the spindle and power train, so in exchange for a less brutal impact (it only hits with the weight of the flail not the weight of the whole rotating assembly) your motor doesn't get ripped up by sudden stalls, and you're unlikely to accidentally launch yourself.

my gut feeling is that even with that 'sensible' bit of design, hellachopper had way too much weapon and not enough wheelbase. the flails don't pivot vertically, so if one flail was kicked up by hitting a vertical spinner drum or shallow wedge armour, the opposite side would bite into the floor and the whole mess would stand up on edge and take off like a wheel skeleton.

>>1033858
too much high power, man.

>>1033813
I think he started with the flail design, then designed the sword arms to fit the same base and still be effective. I'm pretty sure his design limitations went something like 1. Fits the current base 2. Looks Badass and 3. Can hit someone, not really giving a damn about survival.

>>1033858
Unless I'm mistaken, I think his weapon was 2x Ampflow A28-400-F48 running at 12s LiPo. That's a good 20hp of potential motor run through controllers that are maybe only good for 15 of that, so it's no wonder he caught fire a few times.

The real trick with these high-MOIs is to 1. Use a contactor instead of a controller and 2. Use A123 cells, as their higher internal resistance means less amps and also they don't catch fire, just get really unhappy. Works well enough for Tombstone!

We got a new shredder at work today that kinda rekindled my lust for robo destruction. A design has been kicking around my head for a while, any thoughts?

Forgive my crappy paint drawing, crappy phone cam and no scanner, much better with graph paper and a pencil.

The black parts are the chassis. The dark red circles would be the wheels, the solid one being optional or replaced with a caster. The bright red circles are carbide sawblades, and the light blue squares are lances (pneumatic, electromagnetic, whatever works).

Everything will be moved and adjusted for weight distribution and parts clearance of course.

The carbide blades have a gap of about 4-6 inches in between to minimize jamming. They are both turning inward (the right side turning clockwise, the left counterclockwise).

The front lance is mostly there to clear large pieces from between the blades. There will be a shunt behind the blades to funnel any debris out and to the sides.

The rear lance is entirely optional.

The rear profile is mostly there to give an idea of the outer shape. Low to the ground, heaviest armor on the top and bottom, angled extensions on the side (hopefully angled properly so that downward strikes are more likely to glance off). Wheels run through the body, exposed on both sides so the bot can flip over and still drive. Internal tilt switch to automatically reverse the controls so the driver doesn't have to reverse the sticks to drive it. Standard skid steer operation.

In terms of armor, depending on feasabilty and legality, I'm thinking a laminate. A hard, but fairly thin outer layer designed to give a little bit under impact. Beneath that a layer of thick, tough fiber. This would dampen and impact, plus should the outer skin be breached by any kind of sawing, grinding or ripping tool, it would likely clog the tool (the way chainsaw chaps work) last would be a thick, hard spall liner.

>>1033869
>the whole mess would stand up on edge and take off like a wheel skeleton

Fuck the Olympics I want to see robot combat

>>1036774
Olympics are great
Maybe ill be over my mad of the bullshit rules by the time the olympics are over

uh
BUMP?

>>1030996
It would be cool if they gave them all a limited loadout of parts to choose from that changed from episode to episode like one of those competitive cooking shows. That or make a military grade version with guns/splosives/drones/tanks and have country vs country.

>>1033621
Jesus Christ I'm expecting the thing to take off and fly away

OH GOD

>>1038287
Some countries would have an unfair advantage because they have a headstart of a couple of years...

>>1032979
pretty much all angle grinders have series wound brushed motors, they will run on DC, but aren't built for it, so don't expect the brushes to last very long...

its been 2 weeks with no new bot battles im fuckin pissed BOTTY MCBOTFUCKER WHERE U AT you better spoil me the whole rest of the tournament because I'm losing my marbles

the arenafloor is live and over the arena is a neutral net the bots would have 2 contacts

3kw power that would bring out some amazing bots

table saw motors
20kv crt flyback taser
strong electromagnets

hell these things could throw molten lead

Why doesn't someone just make a battlebot thats a steam roller

>>1041686
Weight limit

Bump.

>>1041684
People would just know their opponents over and they would lose power...

>>1041684
Two of the robots there were at 240V DC officially. The Dentist was using a sub-ohm EMRAX airplane motor for a weapon motor, driving it with a Prius motor controller and Road Rash was doing...something... to get some high voltages to run their linear induction motors. No surprise those two didn't compete, it is hard as hell to work with >100v DC systems, shit blows up for no reason.

>>1043811
240vdc shouldn't jump around and rek shit all by itself, but it'll sustain a huge arc once you strike it.
and if you pwm 240v into an inductive motor winding without an adequate snubber and then find the brown note, you'll get pulses of kilovolts back out. just like the hf arc starter on a dc tig or a plasma cutter.

>chomp wining
How? It spent 80% of the fight on its side.

>>1044051
at least it had an active weapon.
And the new biteforce was shit anyway, too fucking unreliable

>>1044056
The weapon flips it over every time.

>>1044058
and that's entertaining.
Wedges are boring

>>1044061
Ok?

>>1044051
The only good thing about it is that this abomination will loose even harder the further it gets. I'm hoping for tombstone or minotaur.

Threadly reminder, the whole season was already spoiled, and its fucking awful.

www.challonge.com/tournaments/2676760/predictions/89692

whoo-wee that beta/nightmare fight was close

was rooting for nightmare to skate along the edge of the arena on their spinner and force a judges decision, but beta managed to push hard

>>1044151
builders have come out saying that's it's incorrect

i suspect someone who attended a showing of the later rounds but didn't go to the finals

>>1044153
>builders have come out saying that's it's incorrect

I suspect that they are just bullshitting people to keep them watching, and to spare them the fact that they were actually spoiled

Why else would he put that bot into the finals?
Not as an educated guess if you only saw part of the tournament.

>>1044166
>>1044153
>>1044151

It's absolutely wrong. He made some....interesting choices for the next round, but common sense should help you figure out how it works.

>>1044058
Flipping yourself over doesn't actually detract from your score. Weird, right?

Judging is FUCKED this season, especially since they went with the new rules right AFTER the SawBlaze/Razorback fight. Usually in sports, it's not the custom to change the rules after the competition has begun.

>>1044151
How is chomp supposed to won against tombstone? Its a tincan, and the hammer can't even reach important parts as long as tombstone keeps facing it.

>>1044170
Since there's literally no chance of you being on one of the winning teams with Brutus's loss: What did losing teams do afterward? Just sit in the audience and watch the rest of the tournament?

I have this (probably inaccurate) mental image of losing teams helping out the team they lost to until the finals are just two big huddles of engineers trying to get their smacked-up bots functional.

>>1044178
Varied. Some people fucked off to enjoy their paid-for vacation in LA, others kept tinkering with their robots in preparation for possible rumbles, most watched the rest of the fights from the audience.

tbqh, there wasn't that much inter-team helping hands in the later stages of the tourney WITH THE PRIME EXCEPTION of Yeti who a lot of people found a way to help with.

>>1044178
Personally, I drank a lot, especially with Basilisk, Scorpios, Wrex, Dick Stuplich, and a few others. Everything got kinda cringy when Ray, Brian, or Brad showed up though.

>>1044058
>>1044051
It is not a perfect design, it's too tall and the hammer arms could be stiffer with some more weight on the end but it does seem to be powerful enough as these sorts of hammers go as chomega showed by flipping itself around the box.

She'd definitely won that fight though, she knew the spot she needed to hit and got lucky right off the bat. Meanwhile bitlessforce pushed chopion around about and got stuck on his own broken chain....

>>1044174
Chomp doesn't stand a chance against either bronco or tombstone but at least it's a million times better than the tumblr bot with a brain she had last year

>>1044178
Some just drank at the hotel.

>>1044260
Chomp's biggest issue was that it was designed to run with magnets providing down force. The arena had a thicker rubber coating than both them and road rash were anticipating and thus the magnets didn't work. This forced Chomp to run FAR from full power and to still flip itself over none stop.

Also since some will find interesting the other robot that had big issues due to the arena floor road rash had some odd magnetic field stuff that was meant to make it move across the floor.
https://www.youtube.com/watch?v=aYSRSGGdsjw

>>1044269
beta had to ditch magnets too.

>>1044260
chomp's arms it's designed to be flexible side to side, but it springs back to shape. In the direction of the hit it is pretty rigid.

I thought beta had this over complicated vacuum set up to suck itself to the arena floor.

>>1044283
it was an early prototype

The Shrederator guy, right? Was his rivalry with Zoe a for-TV thing, or did they genuinely have a beef with each other?

>>1044188
How'd things get cringy with Ray? Online at least from my dealings with him he seems fairly nice and chill.

>>1044535
I swear Nave is theredpill incarnate, the shit he says and does is pretty crigeworthy. Zoe is certainly your standard SJW/3rd waver or whatever, but she's very respectful to people that she knows personally. He had a beef with her, she just doesn't have beefs with people she knows.

>>1044539
When those two showed up it would turn into old guy 'let's talk about how great things used to be back in the day' time, and since Ray's got his reputation, people tend to shut up and the conversation becomes almost exclusively about them.

Have you ever seen boomers who are really into a hobby, any hobby, talk with each other? That's what it was, and it made me pretty self-concious of how much money I had just spent and how much of my life I just burned on a hobby.

At least with most of the other guys we would shoot the shit on each other's life stories, fuckery we did to get here, and where we were going in the future; our after-hours conversations were maybe only a quarter to half about Battlebots. When Ray or any of the other old-timers showed up, it was exclusive about "back in the day when things were more hardcore"

Robots!

Would you be allowed to build a welder onto your robot?

What about defensive weapons like shooting Kevlar webbing to jam up the spinner bots?

>>1046199
We don't actually know about the welder. The answer is probably no, but I would love to make a robot that DQ's the other one by physically making it >250lbs by the end of the match

Entanglement like lines and nets are a big no-no. They kinda make things boring anyhow, they'll disable all the exciting parts of another robot without a bang or a boom.

>>1046212
what about using that house insulation spray to clog up the robots?

super battle droid! take him down!

Tombstone almost went down

>Holy shit Bombshell you fucking idiot!!

Oh wait nvm

Poor bronco

Witchdoctor boooooooo, but wrex yesssssss

>>1046801

tfw would have preferred the modular one to win

oh well, at least it got #2

>>1047673
eh, I'm happy they are out. Never gotten along well with Mike Jeffries

seems like a fourth of the competitors this year went in with an anti-tombstone design, and tombstone still came out on top. definitely deserve props

bombshell's upset over minotaur was absolutely incredible though

That was my experience around Ray and Brian as well. Nice guys, but everything turns into the same conversation about how the older days of robot combat was better and brighter and grander than it is now.

> You want to make an unstoppable 'bot for something like this? Heavy, hardened, high-speed, well-supported spinning weapon, mounted on a nice, thick, heavy base, with hidden wheels, and nice thick armor on the sides. It's like a Viking berzerker warrior with a battleaxe; you get that thing up to speed before anyone can get inside your weapons range, and it's a foregone conclusion that anyone coming near enough is going to get torn to pieces.

Consider a simple 1" vertical steel bar well connected to a heavy chassis at the same distance to the centre of gravity of a bot as the tip of the blade of the spinner. You aren't going to tear that to pieces.

Pound for pound you can defensive structures much stronger than the spinner, which needs to worry about a bearing. Spinners win because people keep making flimsy shit available to be hit by spinners.

>>1047641
Yea I think they had the best shot against tombstone this year, their back wedge would have been devastating to tombstones spinner.

Fainting

>>1047641
don't like the inertia labs guys: they always looks so serious.

Just started watching, holy hell it's amazing. Much better than the British robot wars

Are they stuck with HSS saw blades? Thinkin about red devil - seems crazy not to have a diamond or tungsten blade against anything that requires a quick bite

>>1050499
Saw blaze used a pretty pricey saw from a specialty company that sponsored them that makes demolotion/rescuse saws for first responders. (video of it cutting shit https://www.youtube.com/watch?v=K1BGP3Xy__E))

Red devil used a HSS body carbide tipped saw , you can see the brazed on carbide tips in the photos of it.

>>1050499
>>1050512
And Skorpios used a custom-made AR500 disc with carbide chips vacuum-welded on.

https://www.youtube.com/watch?v=M5Lgpsl71EI

Diamond blades are also only pretty appropriate for cutting ceramics, anyway.

I love the Yeti story this season
Usually I hate all the drama/behind the scenes stuff, but those guys just seem so nice and genuine. And the fact that they're so under prepared is great haha

Would it be legal to cover your robot with carpet strands and hair?

You know, the kind that stop vacuum cleaners dead in their tracks

>>1051020
Entanglement isn't allowed

>>1027041
We all ready have a bot that is really killer so why not?

>>1051025
>>1046212
>Entanglement like lines and nets are a big no-no.

That's so fucking gay.

>>1051479
Would you want to watch battlebots where all it was one team with a giant net trying to bind up the works of anything that spins or just trying to jam up the drive trains?

>>1051025
I've been thinking about that, would grid armor be allowed? Using metal grids welded to a surface as ablative armor? Entanglement would be a consequence of it being hit by a spinner, and very unlikelly

I'd love to see something that sprays liquid nitrogen to weaken metal.

>>1027045
what motors and gearboxes are those?

>>1053021
brushed can motors, epicyclic gearboxes.

might be old twr15s or magnum 775s but it's basically the guts of a cordless drill, so it could've been produced by anyone.
