This is the most dangerous robot I've ever built. It's also the most massive, with the most destructive pair of hammer smashers and the most menacing set of googly eyes, along with some other surprises. Because I was challenged to a robot battle against five dudes I know, but this was hardly a fair fight because it would be their five robots against just one of mine. And given that the only rule was that there are no rules. As you might expect, things escalated very quickly with a few surprises. Cody: It’s the coolest thing I’ve ever seen. A good bit of danger. You got to do what you got to do and a lot of carnage. Cody: Ohh sh... And since the winner of the battle got free reign to completely redecorate the loser's headquarters, the trash talking commenced immediately. How are you guys feeling? Tyler: If you get past Garrett, I'll be shocked. Mark: Wow.

Mark: What, you don't even think I'll make it to the final round. Tyler: Home team's got to feel pretty good about it, too. Garret: I'm at about a 2, to be honest with you. Cody: Fake it. Sparky: All right, gentlemen, I want a clean fight. Sparky: I want to abide by the rules. Mark: There are no rules. Sparky: Exactly. Let's battle some bots. What do you say? Tyler: Let's do it. It was time for the dudes to lay eyes on what would be their undoing. Gentlemen, the cybertank. Wooahhh. Dude! Wait. Does this violate a rule? Tyler: No, no. No, it doesn't. Mark: Oh, right. So, with the lack of rules fully established, it was time for the cyber tank to start mercilessly working her way up the dude chain, starting first with Cody. Cody: May I present to you R2D2.

from a galaxy far, far away came the first challenger. Mark: Wait, I think there’s a height issue. Tyler: Is that as much as the door opens up? Cody: It doesn’t fit. Alright, hold on. Tyler: Did you not think about the height restrictions, Cody? Mark: Guys, this is a bad start. Tyler: We know, Mark, we're not smart. Coby: Yeah, we get it. But once we have the droid we were looking for. Cody: Enable taser. Cody: Alright, Marky. Cody engaged both his taser system. Mark: Wow. And his squirt gun system. Dudes: Ohhhh. In an attempt to short circuit my robot. But unfortunately for the dudes. Mark: The cybertank is waterproof. Tyler: Ohh, he’s still alive. Dudes: Ohhhh. OK. Mark: But that mustache there is not just for decoration. Because what they didn’t realize is that with a simple motorized retraction of a quarter-inch steel cable.

cyber tank's fashionable mustache doubled as a nine-pointed, razor-sharp ramming bayonet. Mark: I promise this will be quick and painless. Dudes: Heyyy. Tyler: Mark, stop! Mark: Ramming speed. Tyler: Do something. Cody: Seriously, stop! Tyler: Hey, you might want to take a look at what’s inside R2. Do we have the live feed? Mark: That’s in the robot? Cody: It’s inside the robot. Dudes: YEAHH. Tyler: You can’t attack!! And while we did say no rules, turns out it was an oversight on my part. Thinking the Geneva Conventions still applied, Tyler: Surrender and not risk a squirrel’s innocent life. And so with my controller turned off, Tyler: Dump your water. Cody: Ok, ok, ok, ok. Cody overconfidently decided to take a cheap shot, Dudes: What, ohh. Tyler: You missed! You missed. Cody: I’m sorry, I'm new at this.

which unfortunately exposed the inside of his empty robot. Mark: wait which meant the live squirrel video feed was just a clever ruse. And nothing gets me more angry than getting clever Rused. So I got back to work, Dudes: Noooo! Ohhhh! Cody: He pork chopped me. Garrett: get away, get away, get away. Cory: Run away, run away. Dudes: ohhhh and I didn't come home from work. Cody: I’m alive. I’m alive. I’m alive. I’m alive. dudes: ohhhhh until there was no doubt. Cody: I’m cut in half. Coby: He’s still alive. Dudes: ohhhh who won round one. Dude: ohhhh. Tyler; you’re scewered. Mark: your mistake was involving the squirrel. Dudes: hahaha and with that resounding victory. Coby: we’re taking it up a notch brother. hope you had fun with that one Mark.

It was time for my next victim. Tyler: Welcome to round 2, Mark. Here we go, boys. Cody: C’mon, Mark: two at once. Oh, oh. It was twin robots for the twins, one with laser-guided retractable harpoons and the other packing four angle grinders and an aerial assault drone. But I wasn't worried. Coby: You ready for this, boys? 3, 2, 1. Dudes: Ohhhh. Cory: Yeahhhh. Mark: Ok, this is kinda tricky to track both. Cory: We're not a trash can, Mark. Cody: That’s rude. Mark: Get over here. Cory: I do not like his eyes on me. Coby: Brace yourself. 3, 2, 1, fire. Dudes: Ohhhhh. Mark: Oh, harpoons. It seemed like their goal was to harpoon me, then wrap me up, then grind me down, which made it the perfect time to introduce my countermeasure, known

affectionately as the War Hammers. Powered by a pair of 24-volt DC motors, these babies are capable of independently delivering over 1,000 pounds of force to anything that dares oppose them. If they could easily rip through watermelons and smash up solid concrete, they would have no problem dealing with the set of pesky twin bots. Tyler: hey stay away from those Mark: Ok Coby: i’m fine he can’t reach me Mark: yeahhh Cory: You are flirting with him Coby: i’m fine Dudes: ohhh Mark: ohhh Tyler: ohhh don’t flip it over And while I focus on cornering twin one, twin two launched Operation Glitter Drone, Mark: what is that? Cory: it’s a glitterbomb Mark, maybe you’ve heard of it a glitter-infused black powder surprise designed to penetrate the cyber tank's armor shell,

Dudes: Ohhhh.  
Mark: Ohh wow.  
Tyler: Take that Mark.  
Dudes: Ohhhhh.  
Mark: How dare you? Luckily for me,  
I got a plan for this. Say hello to my tassels.  
Coby: Oh, heads up kid.  
Mark: Yeahhh, hahaha.  
Coby: You might want to drive your car.  
Tyler: Watch out Cory! Noooo.  
Mark: Yeahhh, hahaha.  
Coby: How was he prepared for that?  
Mark: Honestly,  
it was the lucky guess. When in fact, it was not a lucky  
guess because in keeping  
with the spirit of no rules, the week prior,  
I placed a drone in a servo actuated box then had a fake  
delivery driver deliver the fake package  
to Dude Perfect headquarters. So when they all went home  
for the day, a little aerial recon work made  
anticipating their plans  
and designing effective countermeasures  
like anti-drone tassels powered by four 24  
volt leaf blowers.

Fairly straightforward. Mark: ohhhh. Tyler: I gotta say, the streamers were a nice touch. Cory: Why are you clapping for him? Tyler: It was clever. Game recognizes game. That was nice. Coby: cmon but I was done playing nice. Tyler: Oh. Cory: I can't see, I can’t see. Coby: Oh heads up. Coby: this is bad, this is really bad. With the drone out of commission, I now had to face the harpoon. Cory: Help! help mom. Garrett: Fire, Fire! Coby: I’m Going for the wheels which unfortunately for me. Coby: ahhhh. Garrett: Shoot. Mark: ohhhh. Dude: Ohhhhh. Let’s goo was now securely fixed in one of my tires. Mark: Now I'm angry. Coby: Here we go. Their plan was to wrap me up with the harpoon line and then incapacitate me Star Wars style.

so they could angle grind off my war hammers, right back. Garrett: wrap, wrap Coby: Let's go. which is a brilliant tactic Mark: Oh, it's the wrap Garrett: I don't think it’s doing anything Coby unless you have even a basic seventh-grade understanding of the rudimentary laws of physics. Dudes: ohhh Because the relative mass of my cyber tank ensured the retracting harpoon line would just pull him closer to me, on. Coby: Oh he’s dragging me. Dudes: Ohhhh to be perfectly in line with the Warhammer Dudes: Oh, no. and while battling twin 1. I noticed twin two appeared to have stalled out. So I readied the nine-point mustache bayonet to finish the job. job. Mark: Charge! Coby: Get out of there Dudes: ohhhh And that's exactly when I realized it was a trap.

Mark: I’m stuck. And they had once again, clever rused me. Yeah. Coby: Grind him because now that I couldn't move off the wall, I was a perfect sitting duck for the angle grinders to get to work. Oh, Dudes: ohhh. Mark: noooo but thankfully, overconfidence seemed to be the theme for the day. Coby: Ramming speed. Cody: use him as a ramp. Dudes: ohhhh nooo. Tyler: what are you doing? Mark: I’ll take it. I’ll take the assist. Now that my war hammer arm was significantly weakened, my attempts to fight back. Dudes: ohhhh led to disastrous results. Tyler: Ohh he broke the arm off. And with the tide suddenly strongly surging against me, I was left with only one option. Mark: I was going to save this for later but I have no choice. Because pushing that button sends an RF signal.

that triggers a small DC motor on a cam that will then dispense copious amounts of glitter bomb fart spray. And if you place that whole contraption in a fake battery and then bribe a dude perfect team member to place it in the dude's driving box before the match, You suddenly make things much easier on yourself Mark: You got to do what you got to do Dudes: charge, woah, get him Tyler: Fart spraying Mark: it’s bad Dudes: yoooo Coby: i’m leaving Cody: Mark, that’s a dirty move Mark: There’s no rules. I can smell the fart spray from here this is rough and with no one left to stop me. the rest was pretty straightforward. mark: ok i’m unstuck. let’s just get this guy right here mark: for a nice conclusion to round 2. it’s hammer time mark: yeahhh how dare you come against me

Cody: youuuu, youuu Dudes: noooo Mark: yeahhh mark: and that fols is round 2. And so while the febreeze worked its magic. And Sparky attended to the clean up on aisle twin. I challenged the dudes to a five round, rapid fire Crunch Labs toy faceoff. Tyler: This is nice. I get to beat you twice in one video. Mark: woow starting first with our version of Rock em Sock Em robots. Except it's squirrels. And we learn all about the power of hydraulics. Mark: Ohhh, the left hook Coby: got’em upper cut. Send him home Garett: boom boom boom boom Tyler: pow pow pow poww Cody: That's one. Next up was trampoline skee ball, where the first to nine wins. But if you miss, they all reset using the engineering principle of levers.

Cody: too high.  
Coby: one more. one more.  
Garett: C'mon Cory. Garett: Get your mind right. Yeah. Dudes: yeahhhh. Mark: These are my toys. Cody: This is what we do for a living, though. Then it was onto airball where the first to catapult their ball to get stuck in the air stream using the quantda effect wins. Cody: I bet Mark loses. Mark: first one into air wins. Dudes: ohhhh. Tyler: Three. That's Three. Garett: Let’s gooo. yes. yes. yes. Cody: In your face. Woooo. Coby: pound it. Cory: Threee. Mark: Next. Then to a coin spinner battle where we explore the power of ratchets. Mark: Go. Coby: C'mon ping me. Cody: C'mon Coby. Mark: Yessss. Cory: Nooo.

Mark: 2 losses in one day. That’s got to hurt. Final battle. And finally to the carnival duck shoot! Three. Two. One. Go! Where thankfully, Cody distracted himself with a different target. Dudes: Ohhhh Mark: There we go. Thank goodness for the three-point finale. So if you want to build and play with any of these super fun toys, all while learning how to think like an engineer at the same time, just scan this QR code and head over to CrunchLabs.com. Now back in the arena, it was round three against the purple Hoser himself. Let me see what you Garr Purple dozer. Purple dozer. Purple dozer. Oh. Dudes: Ohhhh Tyler: Ohhh yeahhh It appeared to be some kind of small purple bulldozer with two front-mounted nail guns and two in the rear, which to be honest for their pen-ultimate robot seemed a bit underwhelming.

That is, until this happened. Tyler: Ohhh. Flame him. Ohhhh Garrett: Get him. Get him, baby, get him. Yeahhh Dudes: Ohhhh, get him. The flamethrower was melting my tires. Dudes: Flame him up, warping my googly eyes. Dudes: Ohhhh, causing the structure to heat up to the point where it became weak and ductile. Dudes: Ohhh Mark: My arm, which is why it's always handy to equip your robot with a 10-pound bottle of liquid CO2 at 800 psi. Because when the cryogenic solenoid valve releases, fire will lose to ice every time. Dudes: Ohhhhh, with the fire threat neutralized. Now I just had to disable the nail guns. Dudes: Awww Cory: Your nail gun. Nail gun down. That was one. Now the trick would be taking out the other three while at the same time

Tyler: Now. There it is. There it is.  
Garrett: There it is.  
Coby: Get him. Hit him.  
Mark: Nooo. Protecting my tires from the nails. Marks: Ahhhh.  
Dudes: Ohhh. That was two. But it cost me an arm. Mark: Get back here.  
Tyler: Nail him. Nail him. Yeahhh.  
Dudes: Yess. Yeahh. Mark: Oh noo. Nail gun. Garrett: You stop running from me. Number 3 was easier than anticipated. And at this point,  
with no arms left, Dudes: Ohhhh.  
Coby: Dude, you’re bending it. I would have to rely on the cyber stash. Cory: Shave his mustache, dude. And there was number four. Mission accomplished. Mark: You got no flame, you got no nail guns.  
Garrett: You got me, you got me. But this is where Garr  
threw me a curveball. Garrett: I have programmed  
a self-destruct button.

Garrett: Will you do me the honors of pressing it? Mark: Why wouldn't you have just programmed it onto your remote? Garrett: I'm not smart, which was a solid point. And yet he was smart enough to know my Achilles heel. Mark: I’m nothing if not a very curious individual. Mark: I can’t not push the button. Tyler: I know you can’t. Mark: I can't help. And so trading caution for curiosity. The cyber tank mustered the final strength in what little remained of her crumpled right arm. Coby: Maybe, like, three taps. Tyler: Yeah. Yeah! Dudes: Ohhhh. Dudes: Yeah. Mark: Where did that come from? Coby: Got him with the button trick. Things were looking very bad for me at this point. Mark: This is all I got, man. Tyler: I still want to go. And with the cybertank buried and bruised under an actual pool table.

Dudes: Let him in. Tyler: Let’s go. Yes, Tyler chose to kick a man while he's down. Dudes: Yeahhh! Coby: Eat! Eat! Tyler: Ohhh! Let’s go, baby. Ohh. Ohhh, the final bot not only wielded a 30-pound swinging axe that could easily turn the pool table into firewood, Coby: What’s on the front of your thing? But the 63-pound slug of steel on the front. Tyler: Watch this, boys? Mark: That's just gratuitous. Dudes: Ohhhh. Could reach a max angular velocity of 4500 RPMs. Cody: Dude, are we about to win this? Dudes: Yeah, we are. This was very bad news. Bit by bit, the dude systematically ripped apart the cyber tank. Dudes: Ohhh. Just like a greedy child ripping open a Christmas present, Dudes: Ohhh. Wielding a giant axe.

Dudes: Ohhh gooo. And with one final degrading parting shot, Coby: Shave the stache. Dudes: goooo. They shaved her mustache. Mark: The mustache. Tyler: We’ve done it. The celebratory confetti felt a bit premature and insulting, you. Mark: Really confetti given the ref still hadn't given us the final call. Tyler: We're not even engineers, Mark. Tyler: you lost to a bunch of uneducated scribe. How do you feel? Honestly. It's disappointing. Tyler: I bet it is. Dudes: awww. Mark: it's disappointing. You guys actually thought I wouldn't have engineered a backup plan, lights. Garett: what? Mark: soundtrack. Mark: trap door. Tyler: No. Coby: What. Cody: Oh, look at it Lifting. Mark: may I introduce you to. Cody: there's a bot in the bot. Coby: Nooo. Cory: what? Dudes: ohhh.

Mark: yeahhh.  
Tyler: Oh okay. That's right. Inside the Cyber Tank all along was my Trojan rat. Saved for just such an occasion like this. What makes fat tail so special are those two unassuming prongs on the front. Because inside there's a 16-pound flywheel that's spinning at 3600 rpm. And when these two solenoids force clutch against the flywheel, that then twists up this bundle of super strong cords, which makes them get shorter, which then actuated this rack and pinion, causing the nose of Fat tail to raise with an incredible amount of force. The force is so great. In fact, it can launch a 250-pound payload 20ft into the air. Ohhhh. These anvils literally damaged solid wood beams on my ceiling. And if it could do that to a few 50-pound anvils, just imagine what it could do to something built by dudes.

who make ping pong trick shots for a living. Dudes: ohhhh Coby: Oh this is bad. Tyler: Hey don't attack yet. Tyler: We gotta reset. We gotta reset it. Tyler: Sparky, clear the arena. By the way, we signed a bunch of the busted robot pieces. Sparky is cleaning up here so go watch Dude Perfect’s video to find out how you can get your hands on some of it. Mark: Ok. Final Match. Cory: Bring it Rober. Coby: Mark I need to know something. Is this the last robot? Dudes: hahaha. Mark: hahaha This was it. No more twists, no more turns. Tyler: Spinner engaged. Just pure carnage. Mark: Let's goooo. Coby: c'mon Ty, yeah baby run the wheel. Dudes: Let’s gooo. Cody: That was quick. Mark: I'll do you a favor and spin you back over.

Cody: Ohhh.  
Tyler: That one hurt.  
Dudes: Ohhh.  
Cory: Oh, that’s insane.  
Garett: No, no, no, no, no.  
Coby: Spin your wheel.  
Dudes: Ohhh.  
Cody: That’s the coolest thing I’ve ever seen.  
Tyler: Oh, I’m alive. I’m alive. I’m alive.  
Cory: Yes. Thank you. Thank you. Get him, Ty.  
Garett: Get away. Get away. Get away.  
Coby: Rip him. Rip his head off.  
Mark: Ok. Ok.  
Cody: Hahaha.  
Coby: I hate this.  
Tyler: Noo.  
Dudes: Nooo.  
Mark: Yeahhh.  
Cory: Ohh, I don't like this.  
Coby: I don't like that.  
Cory: You just need one good punch.  
Cody: Use your axe.  
Tyler: I'm trying.  
Cory: Ohh, that was cool. That was cool.  
Dudes: Ohhhh.  
Mark: That’s for the confetti.

It was time. Tyler: I’m fine. I’m fine. Dudes: ohhhh to finish this. Cody: you’re not fine. Mark: let’s gooo with more of an engineering trick shot. Dudes: ahhhh. Oh my gosh. Mark: and stay out with the board cleared. Fat Tail was free to play with her lifeless prey. To the dismay of the losers. Cody: Ohhh. oh you’re still good dude. Mark: oh nooo. Don’t hit my tail. ahh One last throw couldn't hurt. Dude: ohhhh. Mark: oh no. Or maybe it could. Tyler: Hey guys. I think we lost. Garrett: This is our white flag. We throw it. As you can see we legitimately damaged the walls of their actual warehouse. Sparky: That’s a TKO. Mark Rober Robot battle champion. Garrett: Your reputation was on the line. Mark: I think umm.. the only thing left

Tyler: We still got to do that.  
Mark: You boys better get to work.  
Cody: Hey, get in there nice and deep like.  
Coby: We're trying.  
Mark: Hey fellas. You’re missing a spot.  
Tyler: We're doing our best, Mark. We're not painters.  
If you’ve ever wanted to know how to make and build really fun things, CrunchLabs has you covered.  
Because for kids, we've got Build Box, and then for teens and adults, we've got Hack Pack.  
In both cases, they get delivered right to your door, where we build them together and learn all the really cool science and physics that make them work.  
With Build Box, we set the foundation by building a super fun mechanical toy each month, which makes it a great first step for learning how to think like an engineer.  
Then for Hack Pack, we take it up a notch with a really cool robot that will work right out of the box.  
No programming required.

but then as a fun incentive to dig in and tweak the code. We make it easy to level up the robot's capabilities using the online coding module. So if you want to enhance or even just take the first step of unlocking the really fun and rewarding hobby of making stuff, just go to Crunchlabs.com or use the link in the video description where to say thank you. We're giving away either 1 or 2 boxes as a back to school special. Thanks for watching.

Mark Rober vs Dude Perfect- Ultimate Robot Battle

Former NASA engineer. Current CrunchLabs founder and friend of science.

Answers to some common questions:

1) I make a monthly toy we build together on a video, that gets delivered to your house that teaches you to think like an engineer.  Check it out at- https://crunchlabs.com
2) I studied Mechanical Engineering in School.  I did my undergrad at BYU and Masters at USC.
3) I worked for NASA JPL for 9 years, 7 of which were working on the Curiosity Rover (I made a video about it you should def totes watch cause it's probably my favorite of all my videos).  Then I made some Halloween costumes.  Then I worked for Apple in their Special Projects Group doing Product Design as a Mechanical Engineer for 5 years. Then in 2022 I created CrunchLabs to deliver monthly toys that teach you to think like an engineer.
