honestly, so long as you can drive really good then you probably could. orbitron uses an ai to literally just orbit the enemy before going in for the kill, i'd assume their movements would be at least somewhat predictable.
@@ReDelta101"random obscure bots like Biohazard" What in the fuck are you talking about? Biohazard won four championships. That's like saying "obscure bots like Bite Force".
Just some suggestions: - Bigger weapon that is further inside the shell (so same point where you hit opponent, but more of the weapon is protected). - Paper mache toppings up top (only dangerous when facing a flame but also hilarious for the same reason). - Color the wheel to match the toppings (green wheel?). Other than that I just want to say that I love the design, and seeing it work at this weight class makes me giddy with joy. I love all the unconventional robots (NHRL whack bots are amongst my favourites and seeing bots like Timber Viper and Monkfish do well also makes me so happy).
The final shot from the animated intro is perfect for merch. Probably just swap out the white effect with some smaller lightning, so it doesn't overlap the letters. And it'd be good to go.
im kind of impressed how well the shell held up despite being made of plastic. like, yeah it got chunks bitten out of it but the other team didnt get to any of the taco insides
I love the taco. Proving grounds is such a great concept since it allows first time builders to actually get some box time and figure out the flaws before entering a trash bot into the championship. Also funny that there are now two food-themed bots with some cool innovation behind them (ripperoni with the counter-flywheel system and now the taco with T drive). I get the dislike for omni-wheels since they can be pretty delicate but your turning wheel is pretty big and seemingly well protected by the frame so you should be able to build something really sturdy. You can also look into some kind of wheel thread type in the form of bristles or something else that will help maintain grip in one direction while allowing it to slide more easily in the other, but an omni-wheel is probably the best solution.
Oh i loved his little bot as well, i am also kinda hoping he makes an ant wieght Burrito or Bot-rito same drive system, and a horizontal spinner would be funny because it could just roll across the arena till it self righted
if you're not fully locked in on the dual discs, another way to protect the belts more would just be a larger disc- the belts get hit because the disc doesn't stick out far enough to hit the opponent before they hit your hub! this would also seriously improve KO power, crucial since you'll probably never win a shoving match
This would also give the option to have the whole weapon assembly further inside the bot where the point of contact is still the same but more of the shell is covering the sides.
If you have the time and bandwidth, look into designing your own omniwheel. The "official" ones are used for 360 degree movement/force application (and have some shortcomings) whereas yours has to apply force in one axis and roll in the other - much simpler/more robust and you could likely get there with a bunch of wheels on a hoop.
I reccomend this so much too. In regards to the design requirements the "omniwheel" would only need to go back and forth in two directions. So it would be more of a "dual-wheel". One large wheel with multiple smaller wheels fixed around it´s circumference would likely work quite well. In the back forth direction it would roll free, and if rotated sideways the wheel would grip. The benefit is that a quiet grippy wheel surface could be used and make for a lot of traction sideways, but impact the back and forwards drive very little.
I freaking love watching a huge taco move like a submarine around the Battlebox. Oh my god, I hope the TV show gets confirmed for a second season and Taco Tuesday gets featured. Complete side note: Damn, dude’s got eyes like freshly calved glacier. Good god.
The belts jumped to my eye immediately and I was not really surprised when they got wrecked. Personally, in addition to the dual blade arrangement I would also add some form of shielding. That could safe it from an accidental hit. If you really don´t want to go with some form of multidirectional wheel, I would throw another Idea in. A hard wheel with a sharp "skid" profile. Kind of like ice skate skids. As the arena floor is steel, you would need quite the hard material, either, depending on what steel the floor is made from, hardened steel or carbide, but it could work. The profile is parallel to the back and forward direction, so when driving it slides over the floor, but when turned the sharp skids turn into teeth that grip the steel floors and give traction.
That’s actually twice a battlebot fight has had one bot win the first day, and then the second day the bot that won the previous day suffered a knockout. It first happened with Doom and Horizon, and now it’s happened with this
Carter , I am so happy you got to do this. I have been watching you for many years. I am especially happy you got a win against disarray. Also I designed a Lego version of Taco Tuesday
yaaa.... Krave only really works with a trap door, that's the unfortunate reality. It's too large to have enough weight left over for a decent weapon....
How about two front wheels. That would allow you to have differential steering and give you a lot more traction. It would also stop the thing from flopping over on its side all the time which would probably help with control.
Great showing. Congrats on the trip to Vegas. Raise or tilt the yaw wheel up with some sort of actuator when using fwd/rev. That way the taco shell drags on the floor instead of the wheel.
How about putting some rubber vibration dampers between the shell and its connections to the frame? That way the shock vibrations to the frame and internals would be reduced immensely and make the bot much harder to kill and able to tank more shots thus requiring less maintenance even between "safe" fights. They don't have to be very thick or add much weight. Regarding the weapon: still think the mono bar is the best option. You don't even need to make it heavier, just a little thinner on the axial size (in other words making it less "wide angle") and longer so that it has more reach and bite for the same mass. More reach would allow to sit the weapon assembly deeper into the taco so the belts would be harder to reach or allow to put a steel cover cover over the belts like some vert spinners already do. Good luck!
The rubber idea was actually part of the initial design, I think team overhaul calls them “wubs”. We ended up not doing it simply due to time and weight, but V1.5 we may bring that idea back. My general combat robot building philosophy is (1) “empty space totally counts as armor”, and (2) “bend so you don’t break,” and rubber spacers are aligned with both of these goals. Re. The weapon…. Yeah, you might be right. We may take a look at the deathroll weapon, and learn from that.
Great video! Love battle bots and love this concept. Was pretty cool to have the personal perspective and ride along. Good luck! Can't wait to see you guys in the main event! 😎
Would be cool if the steering wheel was on a little swivel-joint that raises and lowers the wheel a little bit. When ever you spin the rear wheel, it would drop down at the same time and hit the ground, but when you don't spin it, a spring would pull it back up so it could just drag the rear of the taco freely on the ground. Not sure if that would still allow for responsive steering, and it would still break the forward motion as soon as you try to turn, but might be worth a try. Having that mechanism inside the taco would probably be better than trying some kind of vulnerable omniwheel setup.
That was great amazing to see it in action that hit and flip was perfect, great work from all of you that made it, looking forward to seeing more. =D Shame about the grippy battle box holding it back, Omniwheels are good, but stock ones might be too fragile, and custom one might be hella expensive, all pros and cons lol
This is my new favorite Battlebot. I won't say why, I now may be a tad biased. Merch is definitely a good direction as you gain more traction. Count me in on a hoody.
I love this bot and thanks for the these videos. I would love to start building one and have an idea just as unique, but first I would have to hit the Poweball to hire people that know how to build one. my concept is well tested at a much larger scale than would fit inside the arena
Look up the wheel that a Smartdrive for a wheelchair has, its got little rollers on it so you can turn the wheelchair, yet pushes straight on with no issue. Works really well for me and would do exactly what you want. You could likely make one yourself fairly easily.
Mmm... If you use a double vertical spinner, could you have the 2 blades running slightly askew to provide cover to the central belt? Should still save money on a beater bar. I haven't seen anyone running a similar concept, so I'm not sure if it's arguably harder on a design point of view or just not practical. I also realized that "Just not Practical" would be a great name for a bot :)
ive been waiting so long for this vid could do with some wedgelets beside the weapon for those nasty wedges if you could lose some weight somewhere or try to incorperate the needle like you did with your ant weight
@@CarterHurd Some times The narration was consistent but the background sounds from the footage too loud or the other way around. I would normalize the sound of the footage you use. Than i would normalize the volume of your narration so it is all consistent. After normalizing you don't need to worry for peaks and such, but it introduces other problems if you have a huge difference in volume in the source. Then you joust need to adjust the volume of both tracks, till you are happy.
The main issue is the voiceover, which gets a little hard to make out over the battle scenes especially. I think if you just bump up the VO by a few decibels you'll be fine. (I love this robot and I really hope we see it on the show one day!)
Honestly speaking, I have faith in Taco Tuesday. At first glance I thought it might just be a joke bot. I mean, it looks unusual. But then you win a fight against a bot that looks more/less traditional. That could be promising. It might take a few attempts like Huge did, but it will be competitive at some point.
No substance to my Omni wheel dismissal? I didn’t think I needed to elaborate, the complexity and fragility is obvious One cheap and simple off the shelf part, vs a custom fabrication project consisting of… well let’s say the Omni wheel has 30 rollers… each will need 2 bearings… that’s 30*3… and each roller will need an axle, so make that 30*4 = 120 brand new components to add to the design. Vs 1 single component. The question is whether 120 additional parts, plus designing and CNCing a custom central hub and making some spares is worth the decrease in friction when sliding sideways vs alternative solutions. It may be worth it. We shall see. But the cons are clear. EDIT: I’m sorry if this was mean. Not trying to be mean. Just things that seem simple become complicated once you need to make them robust enough to survive combat.
Maybe your front drive wheel could be a lot bigger to give more traction, as long as it's inside the taco? There was no substance to your Omni wheel dismissal.
I’m super curious what you dislike about an Omni wheel for the steering wheel application. It seems like the perfect thing, in terms of the functionality you’re after. Slips fully in the direction you need it to, grips fully in the direction you need it to. Is it a fragility issue? Could do a UHMW wheel with tpu rollers that’d be able to take a ton of abuse. It just seems like exactly the right use case, but I imagine you have a good reason.
@@CarterHurd Definitely understandable. Idk if you’ve watched James Bruton’s channel, but he makes super large Omni wheels (bike sized wheels) a lot, and I think if you followed a similar process but CNC’d the main piece out of one hunk of uhmw and printed the rollers in tpu or used some metal rollers, it’d be a nice end result. Might have to do two pieces of UHMW for significant cost savings. I think it’s at least worth pricing out. Hope to see you guys accepted on the show or on another proving grounds!
Yeah, that would make it about 50lbs overweight, though, even with thin titanium. If we wanted a metal shell we’d need to scale the whole thing down to copperhead-size. There are pros and cons to having a large robot vs something compact like minotaur: one con is the need to use less dense materials.
I understand why you would be sceptical of omi wheels but some of the larger thin version like @jamesbruton had made in the past would be perfect for this build
Does PCBWay basically pay for _all_ creator RU-vid content these days? Please don't take that as a complaint, but I think it's time I buy them a toothbrush and give them my spare key. But really, let's Tacobotit PCBWay.
you know what… I wonder if the JB weld for plastic could be used to fill in holes in the UHMW. Idk if the bond is strong enough for it to be structural, but…
Just more complex: More parts, more complicated, heavier, kinda difficult to make super durable I like them in other applications. Just not for combat robots.
10k for the egg beater sounds crazy......What material do you need?? Do they have to be one piece? If you did a multi steel layup, weld, then bolt it together could probably make it for 2k or so. Message me if interested
You can’t typically get away worth normal steel, you want Hardox (our spinner was Hardox 450 and even that only lasted 2 fights). And yes, it needs to be 1 piece. Hardox basically restricts you to either waterjet (this is what we used) or wire EDM. Feel free to email me at carterhurdrobotics@gmail
Composite/welded weapons are inherently fragile compared to single-piece and with a beater type weapon it will surely crack on the welds since the stresses will be located in just a couple of points. You have to imagine that you're hitting your welded thing on something that is also welded steel, the stress goes both ways. Many people have tried and it only really works at lighter weight classes. There are also teams that tried dado-like stacks of discs to form a beater but the problem there is that you lose most of the moment-of-inertia advantages that a beater bar has, since it's carrying more weight in the center of the weapon that doesn't help much. The super high cost for beater weapons is due to it having to be machined out of a single block of abrasion resistant (AR or Hardox) or even tool steel (which is ridiculously tough to work with and a lot more expensive than just standard mild steel from just sheer machining/cutting hours), and then it has to be heat-treated by a special company that can work with such huge pieces of steel and takes literal days in ovens and slowly cooling down.
Well, I always wanted to be on Robot Wars. But I got no robot building experience. And BBC cancelled it. Twice. Maybe if it gets revived again, y'all can travel to the U.K. and enter your robot in it.
@CarterHurd ahh I see. I guess I can understand knowing omniwheels are prone to jamming due to debris However I am attempting to solve this for my antweight bot.
