The COOLEST Things We Saw At OPEN SAUCE 2026!!!

[00:00:00][music] [music] [music] [music] [music] Well, Welcome to the 2026 Open Sauce Convention. That's right, for the fourth year in a row, Bot Bash is back here along with Scorpios and the Battlebots.

[00:00:40]Uh, one unfortunate thing this year is the fire marshall shut down uh the robot area. So, the hockey tournament got turned into just watching the FIFA World Cup, but we still had a pretty good time. But please understand, that's why you don't see a lot of robot fighting footage in this video.

[00:00:59]But creators from all around the world, a bunch of different YouTube channels all showed up to show off their really cool projects. And I did want to take some time to highlight a few of them here. In fact, one project, and I know a lot of people are hoping to see the fight between Tiny Tombstone and the Sting Kit. Unfortunately, that did get delayed as well. However, Ray and I did take the arena off campus and we did do something. So, let's check that out. Hey there, Builder Blog. So, I know I promised you guys a battle with this guy.

[00:01:34]>> Gonna have a battle, just not the battle we promised. [laughter] >> We We are still going to have that fight. Uh either I'm coming up to Sacramento to see Ray or he's coming down to Oakland to see me. We'll figure it out. And we're going to fight in one of the arenas in our backyard. But, uh we do want to deliver something today.

[00:01:51]And since Turbos provided me this nice portable arena, even though Open Sauce will not let us fight robots inside anymore, we are outside of Open Sauce.

[00:02:00]See the welcome to open parking lot.

[00:02:03]>> And so we're going to have a quick battle with sportsman robots right now.

[00:02:08]>> I'm ready to go. Let's do it.

[00:02:10]>> I officially want some more. [laughter] I didn't realize I was going to have to assemble the arena before I had any fun.

[00:02:21]What's going on here?

[00:02:22]>> Hey guys, I wanted to announce that the Sting kit is officially live on turnabot.com.

[00:02:28]So, you could head there, click on bots, and you will see right there on the page. Sting is available to buy right now. If you've ever wanted to support the builder blog, please go buy a kit.

[00:02:40]You could get it both soldered, not soldered, with a charger, and without.

[00:02:44]And please tell them we sent you. Type in code bot bash for a discount. It helps us get a little extra royalties.

[00:02:51]So, let's get back to the match with Ray.

[00:02:54]>> Slower motor in yours has or sorry, the purple one has the really fast motors.

[00:03:01]Blue one has the really torquy motors.

[00:03:05]Okay.

[00:03:08]So, I'm going to ask you and I'll let you pick. Do you like that one more or do you like this one more?

[00:03:16]Definitely slower control.

[00:03:20]>> Red driver, are you ready?

[00:03:21]>> I am ready.

[00:03:23]>> Red driver's ready. Yellow driver is ready. Here we go. Three, two, one, fight. Robots fight. Uhoh. As it looks like a big scoop here, but uh oh, Purple Stake is getting up and under.

[00:03:39]Blue St lines up for assault. Purple darts around. Blue Stake gets up and under. The two robots go toe to toe.

[00:03:46]Purple stick tries to get it, >> but it looks like Blue Stick is up and under.

[00:03:49]>> It's the piouette of death there.

[00:03:51]>> Oh, I had you.

[00:03:54]>> Oh, Blue Stick's got the >> Who's got who? Who's [laughter] got who?

[00:04:00]All right, here we go. Can I set you in there? I don't know. I CAN SET US BOTH in there.

[00:04:07]>> That's two out of three. [laughter] >> Here we go. Three, two, one, fight.

[00:04:15]>> Oh no. Oh no.

[00:04:18]>> See, that was one where the slower one didn't hurt me.

[00:04:21]>> It was a big >> All right. One, one.

[00:04:27]>> Tiebreaker for all.

[00:04:33]>> Are we ready?

[00:04:34]>> Three, two, one, fight.

[00:04:43]Not again. Not again. Why is he having >> you?

[00:04:53]All right. Hello. I'm going to scratch your back. Here we go.

[00:05:02]>> Who's the champion?

[00:05:03]>> All right. All right. That would be me.

[00:05:06]>> All right. Check out the new They're a lot of fun.

[00:05:09]>> Thank you everyone. Thank you for checking in on the builder block and we will see you soon. This tombstone match is coming tombstone this rig and get to get your revenge on that one. So let's give it a shot. Okay.

[00:05:22]>> All right guys, like and subscribe and check out Ray's channel as well. And we will see you all next week.

[00:05:30]>> Oh my gosh, it's the terrors.

[00:05:33]>> Hello.

[00:05:34]>> Hello.

[00:05:43]A. It's the Woodstock plane.

[00:05:46]>> Tell me when you're ready.

[00:05:47]>> Yeah.

[00:05:48]>> All right. So, here we have a little bit of a unique bristlebot. It name is Double Dutch. Most bristlebots go where they want to go. However, this one, although the although the weapons share one motor, so they all turn together, they can change the angle of the bristles so that you can control and go forward or back or left or right.

[00:06:11]>> Oh, very cool.

[00:06:14]>> Have you uh this is in plants, right? Uh how you >> This is a plant. So, it's a one lb plastic. No metal weapons. However, this one because of the bristles gets weigh 1.5 lbs. Oh, >> the other interesting thing is um getting the right amount of vibration is difficult. So rather than designing it correctly, I just drilled holes until it vibrated about the right amount.

[00:06:39]>> Oh, that's one way to do it. Okay.

[00:06:41]>> Not the best way, not a good way, but it worked.

[00:06:45]>> That's what's important, I guess.

[00:06:46]>> Yep.

[00:06:47]>> How much of the weight is in the weapon?

[00:06:51]>> I don't remember. It's uh the weapons are very very heavy for a weight class.

[00:06:57]Uh I don't remember the the weight unfortunately. Oh, one more interesting thing. If you'll notice here, there are no layer lines for it to split on because every piece has been printed flat on the bed.

[00:07:11]>> Oh.

[00:07:11]>> So that it doesn't break. This chassis has been through six competitions without repair.

[00:07:18]>> Oh wow. That's pretty tough.

[00:07:20]>> Yeah. So it's extra extra durable. H.

[00:07:24]>> Yeah. Usually see a lot of destruction in plastic gans, but very impressive for something to last that long.

[00:07:29]>> Yes.

[00:07:31]>> Now, it lost because it got tipped and got stuck, but it was not. But the damage is almost nothing.

[00:07:42]>> Oh.

[00:07:43]Are all those marks and stuff from all the the beater bars?

[00:07:46]>> Yes, those are from those are from other people trying to hit me.

[00:07:50]>> Oh.

[00:07:53]And does the roll cage uh you said you got stuck on the side. Is the roll cage supposed to help it to roll back on its side?

[00:07:59]>> It's supposed to, but it doesn't work very well.

[00:08:01]>> Oh, I see.

[00:08:03]Very interesting.

[00:08:06]>> Work in progress.

[00:08:08]>> That's looking good.

[00:08:10]>> All right. Thanks, Grant.

[00:08:11]>> Thank you.

[00:08:16]>> Oh my god.

[00:08:19]Hey imperial scanning devices I suppose so All right. So, are you getting ready for battlebots? Is that what this is?

[00:08:57]>> Could be. Looks ready, right?

[00:09:02]>> Yeah. It It looks very General Grievous, like you can hook four lightsabers up to this.

[00:09:07]>> I would not want to encounter that on the sidewalk. [laughter] >> So, so what is this? So yeah, this is uh Striker the drumming robot. Uh roboticist Val here. He's been working on the for the last 10 years. It's been kind of a learning project, a personal project to learn robotics and engineering and and kind of go in the deep end.

[00:09:27]>> Well, I have to say that thing is damn impressive.

[00:09:32]>> So the um the most difficult part was these arms were aluminum casting process.

[00:09:39]>> Wow.

[00:09:49]Hi there, guys. Can I film you for my blog?

[00:09:53]>> All right. So, I I have to admit a lot of people ask me when they see my videos, I have all my nice tools sorted and printed. And since you guys are responsible for about a third of my holders, >> I felt you should get the honors to tell people what you do. So there's their QR code. So what is this?

[00:10:13]>> This is Tool Trace AI. Um it's just a free website. Allows you to take a photo of your tools. It creates a 2D outline of it. Then you can like 3D print tool organizers, laser cut foam for tool boxes, really anything you want.

[00:10:28]>> That is awesome. And this is something I have used in my own shop. And it makes such amazing holders, calipers that perfectly fit. You don't have to drill out little holes because the models Oh my god, I have this like exact thing.

[00:10:45]So, I just want to say guys, thank you for an amazing product.

[00:10:49]>> Thanks for using us.

[00:10:53]>> Okay, we'll just go with it. Um, >> all right. So, what is Spark Blocks?

[00:10:59]What is this?

[00:11:00]>> Spark Blocks is just a simple electronic system that's embedded in Lego compatible blocks.

[00:11:06]Super easy to build your first circuit is an LED and LEDs only work in one direction. So through trial and error, we're going to learn all about how circuits work.

[00:11:18]From LEDs to motors to speakers and sound, this kit comes with everything you need to learn about what you can achieve.

[00:11:32]>> So what is it? It's playful. It's fun.

[00:11:35]And it is advanced when you get up to higher levels. So at this low level, beginning level, you can't go wrong. You can't do anything that's going to hurt the system. So kids and parents can experiment. And once we get more advanced, we get into transistors, resistors, capacitors, and this is a robot that naturally runs away from life.

[00:11:58]And this can be built with the expansion kit in the intro kit. In addition, to make things easy with the kits, we've embedded most of the electronics into the intro kit and then we've added add-on kits. Now, these are just an idea. Just all the bricks come in the add-on kit, but imagine what you could build with a direct drive motor coming to you.

[00:12:22]>> Oh, there we go. It's not the off-road version. We're hoping someone, [laughter] >> but that's our excitement. We're hoping people will build an amazing thing.

[00:12:35]>> Well, that is awesome. Thank you for taking the time.

[00:12:37]>> My pleasure. Thanks for being here. Hope it's awesome. It's been awesome.

[00:12:42]>> So, if you pull it up, the whole arm is going to go up. If you pull it towards you, the whole arm's going to get >> Yes. Yeah. So, right now it's freezing up. It's just a little bit slow while it does it.

[00:12:58]>> Yep. Then it's gonna come forward.

[00:13:02]And it's it's not super touchy, so you can be a little bit dramatic with it.

[00:13:06]And if you pull it pretty far forward, then it will start going.

[00:13:19]>> I don't know if I'm >> You're doing it right. It's It's moving.

[00:13:24]It's just hard to see sometimes because it's not like fast.

[00:13:28]>> Typically the speed it could operate at >> Do you know?

[00:13:32]>> Uh yes, I can I can probably get it moving a little bit faster. Uh but I don't have the faster I move it though.

[00:13:38]What's more likely it is that I like mirrors on where I'm moving in operation. Um >> all right.

[00:13:47]>> 3 2 1 It's semi-automatic.

[00:13:59]>> And actually, we have a three uh three burst shot programmed in as well. Now, hit it again.

[00:14:05]>> It's a three round burst.

[00:14:09]>> Wow. Very cool.

[00:14:14]>> So, uh tell us a bit about this thing.

[00:14:15]So what we're doing is we are shooting these uh steel valves just straight from coming and so what we do is we have a solenoid that just kicks them out of the chain just adds a little bit of energy to get into the first uh field. So we're dumping power straight from these lipos through these MOSFETs and into the coils. As the projectile passes the first coil or actually passes the first gate, we turn this foil off and then turn this one on.

[00:14:43]>> Yeah.

[00:14:44]>> As it clears this gate, we turn this one off.

[00:14:46]>> Why do you need to do that?

[00:14:47]>> Uh so that way we keep uh because the projectile is going to be attracted to the middle of the coil.

[00:14:53]>> And so we don't want to pull the projectile backwards. So we turn them on in sequence in order to ensure it always gets both.

[00:15:01]>> So if you do that three times?

[00:15:03]>> Yeah, we have a three Yeah, we have three stages.

[00:15:06]What kind of currents are you pulling?

[00:15:08]>> So, we're pulling about 500 amps uh at 48 volts.

[00:15:12]>> Wow.

[00:15:12]>> But we're only doing that for about uh 15 milliseconds. So, you can see the the coil timing right here.

[00:15:18]>> That's the launch button.

[00:15:21]>> Press it. Do it.

[00:15:25]>> What did we see now?

[00:15:27]>> What happened? Do it again. And watch the watch the bin.

[00:15:33]>> Yeah. Where where should I if I take a slowmo of this area the best place I think are more like It's making it way over to the cups right now.

[00:16:14]This is actually a version two. We had a version one last year, but we've made a lot of big improvements. One of them being we made it we made it bigger. So, it feels like a vendetting machine.

[00:16:30]>> We still got some rough edges as you see here. Here we have to kind of shake the cup to get it to fall.

[00:16:37]>> Uhoh. Do it six times just to make sure.

[00:16:41]>> We got to make sure the cup is there. So we just shake it some more.

[00:16:47]>> We have to put a sensor in the kitchen to >> Yeah, we should. So actually we do have a weight sensor on the clock, but it's rubbing.

[00:16:54]>> So we just proximity sensor or something.

[00:17:03]All the toppings are kind of different consistencies.

[00:17:06]This one tends to clump up as you see there, but sometimes there is definitely compact it. um that actually get more complex.

[00:17:44]This is also something new.

[00:17:47]Yeah. Um but you know we would you would instead of having like water you already have some simple ideas like the for example you know very zero mechanical engineers in our team which is a All right. So, there you go. There would be your uh your mama if uh if you could eat it. But unfortunately, you cannot eat it. You can take a picture. Take a picture. You don't have a health permit.

[00:18:32][laughter] >> It makes the squeak noises while you swing it. [laughter] >> Shouldn't that be lodged in a TV? Let's be honest.

[00:18:48]>> [laughter] >> If you swing it fast, it's like [laughter] >> probably shouldn't swing it directly at my husband. [laughter] >> Do you guys want to try any of the Lego hair pieces?

[00:19:10]>> I I think we need to try some Lego hair pieces. I I got a haircut recently. I might need a new hairpiece.

[00:19:17]>> Let's see if this fits your head. This is the biggest one that I have.

[00:19:20]>> Oh, you know what? Maybe >> it's a perfect kit. It [laughter] was made for you. You look great.

[00:19:26]>> You look great.

[00:19:27]>> I think you need to grow it back out.

[00:19:29]>> Yes, >> I do, too.

[00:19:30]>> I agree.

[00:19:31]>> The best part is I can't hear anything and it's a really muscle. Ouch.

[00:19:36]>> That's a [laughter] great idea. Perfect.

[00:19:37]It's saw so many.

[00:19:38]>> It's a win-win. I can I can get the the rubber chicken lightsaber and you won't even know.

[00:19:45]>> All you want. Perfect.

[00:19:47]>> Yep. Yep.

[00:19:48]>> Yeah. [laughter] >> Okay. So, why are you making chicken lightsabers and Lego hair pieces full size?

[00:19:58]>> I I make like just a lot of weird stuff in general. Like I've got a a giant wearable croc hat >> like that. Yeah. I I just like when I started 3D printing things, I don't like making like just trinkets that are going to sit on a shelf. I like to have interactive stuff and I'm inspired by making a lot of things based on toys that I had when I was a kid. So, there's a lot of nostalgia stuff. But at some point last year, I made my first lightsaber and I was like, "Oh, oh, oh, this is this is this is the greatest thing ever. I'm going to have to like this is the only thing that I want to do now." So, I I've made a whole bunch of those.

[00:20:34]I've got Jarger Banks here.

[00:20:39][laughter] >> Yeah. And it's even signed by him as well. I met him last week. [laughter] >> I I >> I've seen the uh the thing online where people think Jar Banks is a secret Sith Lord >> and was actually in charge of the whole thing.

[00:20:59]>> Yep. Exactly right.

[00:21:01]>> That's amazing. Do do you know what this is based off of?

[00:21:04]>> It It's the the most disgusting uh suck toy ever.

[00:21:09]>> Yeah. So, [laughter] it's supposed to be a sucker and you're like that's that's a bad idea, right? Like >> I just just tugging jar jar.

[00:21:18]>> You're like I don't know about tongue kissing jar jar. I'm I'll >> pretty sure that was pulled from shelves. Yeah. [laughter] >> I have a feeling that might be one of the most valuable Star Wars toys.

[00:21:28]>> Oh, no. I I think it is. Yeah. I got that one from a friend, so it worked out for me. I didn't have to pay for it.

[00:21:36]>> So, yeah.

[00:21:38]>> All right. Well, I'm walking off with your Lego hands.

[00:21:40]>> Okay. All right.

[00:21:42]>> See you later.

[00:21:42]>> Bye.

[00:21:52]>> It's over, Anakin. I have the high ground.

[00:21:56]>> You underestimate my power.

[00:21:58]>> Don't try it.

[00:22:01]>> [laughter] >> You are my brother.

[00:22:04]>> I hate you.

[00:22:08]>> We didn't rehearse that at all.

[00:22:15]>> How did you get up there?

[00:22:18]>> Ladder.

[00:22:18]>> Ladder. Are you allowed up there?

[00:22:22]>> Awesome.

[00:22:25]>> Well, just cuz Trent's up there doesn't mean you should be. So happy.
