Really excited people like more CAD videos, since I enjoy making them. Here's a quick Q&A for your top questions:
Will the files be available for download? Yes, I'll include a complete STEP file and a bill of materials with the build video. It's not a tutorial, but everything will be free (to download, parts cost is approx. $400 USD)
What is this modeled in? Everything is modeled and animated in Fusion 360.
Why servos for (X) mechanism? Servos are cheap and easy to source. I like to build things that are more approachable and if I use exotic/custom parts, then fewer people can replicate it. This also keeps costs and wiring complexity down since everything's designed to run off of a 2S LiPo. I like the simplicity of that.
idea for the sentry: the size looks like it would be more like a mini sentry, so maybe make it look more like a mini by painting a checker pattern on the... round casing... also add a little alarm to the top to bring it all together (not the screw as it is much more important)
and i also agree with everyone who says to make it fire nerf darts
So are we talking 9mm rounds or ...?
@@sumbo8452 no, nerf darts, the sentry would probably self destruct if it used real bullets
Sounds like the thing is ... under engineered...
What would be cool is if it detects the colour of the clothing someone is wearing and shoots at them if they wear the enemy team colour
And Fire nerf bullets at them

@@Skaetbullliteral war crimes
@@cowserthekhelinace Does a real life version of a turret from a video game that shoots bullets at people have any restrictions written in the geneva suggestions? Probably...
@@cowserthekhelinace might be different for me, I’m in America
Real question now, is do you keep it realistic firing wise or do we go the aperture route, using the whole bullet for 65% more bullet, per bullet?
It can fire really long so i guess aperture route
Science is not about why, it's about why not! Why not fire a whole bullet, that's a 65% more bullet for bullet!
The engineer probably would do that without knowing what Aperture is, owning several PHDs and all that
@@atig51 engi can also smack the turret with a wrench or shoot it with a futuristic gun to reload it.
basically engi is a magician who is too proud to admit it
That's actually not that unrealistic, caseless rounds are a real life invention albeit an unpopular one.
I just found this channel and love what I am now calling “bullying valves understanding of mechanical engineering” - the series
As if TF2 was ever realistic.
would love to make a lv 1 turret as a machinist, also yes, i love me tools
@@kooolainebulger8117 if i were you i would do a mini sentry so i could have an excuse for why it can't be upgraded
If they ever make TF3, with updated graphics and models (though I'm not holding my breath for that possibility), they should hire an engineer who could design sentry turrets that actually woupd function IRL.
Gaem Balance, Or the gunslinger doesnt allow engie to upgrade the sentry in a correct way so he went "Fuck it" and just made a new sentry model just for the gunslinger @@chickennugget481
"The sentry is perfect, well, except for all of the flaws"
You could say that for literally anything
I think you could have managed to get the horizontal turning action on the top hinge without compromising the hinge design at all. Using flywheels and gyroscopic procession, you may be able to get it to rotate by placing said wheel in the round housing of the head assembly. This would likely be even more expensive, wildly complex, incredibly unnecessary, and may not even be possible with your launching mechanism and barrel action assembly, but I thought it was a cool idea.
Ah yes
Add reaction wheels
The Kerbal Space Program method
that would loop right back around to the very first issue of weight though
Technically possible! There's not too much room in the forward housing though, since space has to be left for the barrel and my secret firing mechanism. Also, I want to keep parts simple so that more people can build it. Would be a fun experiment to try in another version though!
MOAR REACTION WHEEEEEEEEEELS@@mihailazar2487
After doing FTC there is a frequency bias in spotting GoBilda components. Spotting them in your build was fun
GoBilda or go home
ah, a fellow FTC nerd, fancy seeing you here! what do you think the next season will be?
@@gamersgambit7517 Unfortunately after doing FRC and graduating I have since moved on and haven't kept up with the teasers :(
Love me some GoBilda! (not sponsored)
Nice to see other ftc people notice the gobilda parts 😂
This already looks like such great build. Can't wait to see it all come together!
And, don't think I don't spot that wrangler in the background at the end you sneak!
WHAT DID YOU EXPECT FROM AN ENGINEER WHO HAS 11 PHDS! OF COURSE IT'S COMPLEX!
You'd think Dell would be German with how complex his design is lmao

He's gotta make the wrangler work like in the game too.
I imagine that he could paint the target with an infrared laser pointer (or automatic garage safety laser) in the wrangler, and the gun will detect and aim at the invisible dot with an infrared sensor.

Barrel recoil makes sense as a solenoid, i feel.
absolutely incredible job. I cannot wait for the next part. you should try making tf2 nerf guns. I've only seen one made.
I assume that one is the Foam-Of-Nature
Great choice for a new project!
Great VO work and editing as always dude, you're making great strides and I'm here for it!
wake up guys Mr Volt built a new valve robot
when I saw this pop up on my recommended field, I had no idea it was going to be about a custom build, I thought it was just going to be about the in-game model.
This is not only fantastically designed, but also fantastically presented! Great job 👏👏👏👏
Amazing build as always. Great job putting in strength where needed.
Thanks Zap!
The fact that the Engineer can assemble this with only a few whacks of his hammer shows his prowess with engineering. Truly marevelous work
He has a wrench
Hammer?!
As a 16 year old trying to self-learn 3dmodeling and engineering, i would love to know if this program you used to model the design is fusion 360 or some other program. The work you do is insane! I couldnt imagine even modeling a single screw of this terrific turret!
he mentioned in a different comment that he's been using Fusion360 for 8 years
Well you started wrong there. You don't model screws on F360 you just add them from a downloadable catalog.
Jk, it is a really powerful yet easy to use software that I recommend to everyone starting or experienced. I started using it like 5 years ago when I bought my first 3D printer and haven't stopped ever since. It is what got me into chasing an Industrial Design degree
I am very impressed at how much you said "JLCPCB" without messing up for that sponsorship.
Also, as a TF2 fan, thank you for making this thing a reality.
This stuff is so cool. It's crazy to see you have over 100k subscribers with just 40 videos. You earned my sub
3:50 The slide-holes in the rear legs are probably a holdover ftom the mount's inspiration, which appears to be the mount for the Maxim MG08 machine gun from WWI.
this is a surprisingly good video. make more, yt needs more quality like this
You GOTTA make it's bullets have 65% more bullet, per bullet just as the other guy said!! (This is a threat)
Made my own lvl 1 sentry with my cad for my printer as well. Had the same issues with the feet and I'm kinda bummed I didn't use the slots like you did! Mine was tiny though and I made almost all the joints felxable (which makes it floppy!!) including the turret itself sliding into the head. What you have done is beautiful, the steel and electronics make it mint.
You can always revisit your sentry :) Thank you! Yeah, the model (if made 100% accurate) has waaaay too many hinges that don't "do" anything IRL. It's mostly to make the building animation easier I imagine.
@@MrVolt absolutely. My design was obviously flimsy as it's tiny and plastic. I'm happy that I can recreate a lot of the sentry animations as almost everything moves. A lot of pins were improvised from paperclips and toothpicks haha. It still stands tall however, and I really like how it turned out. Not sure how to do such tiny ball joints for the feet, thats my biggest disappointment.
I'm a software engineer and info sec person. Mechanical engineering is like black magic to me. Still, videos like these are like catnip for my brain.
DUDE! I was just thinking about you and thinking I hadnt seen an upload for a bit. I"M SO HAPPY!
Holy crap, you just rushed straight through the magnet in the ball foot like you didn't just blow my mind.
this is really cool, I'm glad someone submitted the alternative title "Making a real life model of the TF2 Sentry (Part 1)" for this video to the DeArrow extension, otherwise with only the creator's original title (The Surprisingly Complex Design of a TF2 Sentry) I probably would have never clicked on this lol
I expected just an educational video about the complex design of the sentry, but instead I got an amazing video about an actual sentry!
I have the feeling he knew what he was saying with “I have some balls of steel”
I literally was thinking about your channel and turned on the notifications for it yesterday, then you upload!
The secondary arm under the drum of the turret could be a sort of complex spring-loaded linkage that lightens the load of the drum to allow for more precise quick aiming
"Volt: This tripod mounted lil ol number designed by me... Built by me.... And you best hope..... Not pointed at you"
Next video: The Surprisingly Complex Design of a TF2 Titan
it's early in the morning, i'm having breakfast while watching how to make a lvl1 turret from tf2 IRL, idk why but i feel like today's gonna be a great day
The recoil on the barrel could also have been done with a motor and cam shaft type thing, then you could make it retract quicker than it resets (I feel like that would be more realistic?) based on the cam profile, and set rate of "fire" with motor speed
For the barrel, another idea I had is to spring-load it, and have a mechanism to just push the barrel forward and let go. The loaded spring may be able to provide a satisfying, snappy kick-back more easily than a servo.
(Technically, it would start in the primed/loaded position, then when it "fires" the mechanism would let go, move back, pick it up and push it forward again)
damn i was already a simp for ur stuff before but now i dont know what to call myself, this is beautiful
This is super cool. I was sort of surprised to see that you went with a servo for the recoil--if I'm understanding you right it'll need to rotate both clockwise and counterclockwise for a full fire cycle, right? Have you considered using something like a RC drone motor hooked up to a drop cam to get a nice quick recoil motion, followed by a smooth recovery, all while having your motor only spin in one direction (i.e. fewer sudden rotational accelerations). I'm guessing you've got really good reasons to go the route you did, but it's always interesting to hear about tradeoffs that had to be made.
A few reasons: I already have tons of servos on hand, it can travel the full range of motion I need at the speed I need, it keeps cost/complexity lower for other people to build, and I generally try to keep to one actuator type in a build if I can,.
Im a simple person - I see CAD model, I click and watch video 😃
Jokes aside I like the way you've presented each section of the model, and explained what changes you made and why 💙
Hey dude I’ve been watching your videos since your first couple uploads and I must commend you on your much better editing / video flow. Great to see
i just want to add that this at 8:31 is shaped like the steam logo and it took me too long to notice
Imagine the joy on a spy's face as they're able to just pull up instead of using as a sapper to destroy a sentry
Damn, just today I was thinking about the possibility of making a Mini Sentry.
My man is making Valve technology real
seriously underrated channel, you could be a big as hacksmith industries
4:42he got balls of steal to do that
Such a hype for the next one!! I really love this videos, seeing videogame tech come to life is so exciting
just found your channel and you to amazing projects, really great work!
would also love to know how you're doing these animations as well
4:40 this man has some balls of steel
given that theres still room down the middle im pretty certain this thing will be able to fire airsoft pellets
bro really said "sentry going up" and build a ducking sentry
I don't want to be "That guy" here, but I recently ordered a bunch of parts from the sponsor of this and the service and part quality was excellent.
bro really just turned into an engineer
amazing. i designed a little sentry which turns and beeps, but i just put the axle of a stepper motor straight through the tilting bracket onto the base
The guy making the Killjoy Turret:
"Finally, a worthy opponent, our battle will be legendary!"
I've always thought that if I ever built anything like this it needs a weight on a spring inside that is accelerated by a motor in one direction and then returns until it slams into an end stop to create a violent jerk and sound. Have it repeating a few times a second to make the entire gun shake as if it's firing. Combine that with a well timed ultra bight and short pulse from a red light and you should be able to get something that looks pretty realistic. You have the sound of the metal end stop being hit, the gun visually jerking back and also timed flash of light.
Seems Dell Conagher made a pretty impractical turret design for someone with 11 hard science PHDs
Engie knows what he’s doing he has 11phds in the canon
Damn that's so satisfying to watch
How long did the design process take?
Cool video can’t wait to see the finished product
"Well don't that beat all?"
modeling and engineering skills aside from the animation in fusion here is godlike. better than just explosions, there's so much storytelling,
That turret barrel needed a linear actuator so bad
He doesn’t know how many peoples dreams he just made real
I was like dayum, this guy puts so much work into this?? And then i saw ur face in the middle of the video,
And i was like, riggggth this guy 💪💪💪 awesome work as always 🎩👌
that big ammo drum area is just screaming for a rotating magazine rack (like the n-strike elite hail fire) of stacked katana magazines
I clicked the video because I thought (from the picture) it was going to go into detail about how public restroom urinal flushers work. Definitely not what the video was about. I've never heard of this game, but it's a cool project to build.

"the sentry is perfect!
Except its not perfect"
While I don't care too much about engineering, I really like the models you use and the final result. It's very nice looking.

"Now for the final step, were going to add REAL bullets and test it on my friend :D"
Found you today, going to binge your entire channel because this... is beautiful work.
Good work! Now make a Level 2 sentry.
Nice video! You should make the level 2 and 3 sentries as well as the other engineer buildings next!
Honestly, this gun reminds me of Degtyaryov series of machineguns with their cylindrical magazines. Specifically, the tank version (DT) since it seems to hold its cartridges vertically. The caliber is largely over-exaggerated, but a more realistic version of this gun would probably be a DT with no stock or pistol grip, and much bigger legs to hold the sustained fire of full-sized cartridges aside from a buttload of sensors. Engineer is Texan, so either he just uses 7.62x51 NATO or smuggles 7.62x54r. However, with that caliber, it might as well be an automatic grenade launcher.
This is incredibly well done, bravo!
This is why I love engineering.
I get to make my favorite game weapons real.
Meet the Engineer-ing skills of this guy!
Valve has a hiigh tentancy to make turrets have 3 legs
You've heard of Engineer gaming, now get ready for

Uncle dane explaining how to survive the ubered heavy in your face
Here before Volt makes a video about the Rescue Ranger next decade.
Interesting choice for the recoil mechanism. I would’ve thought a design similar to a steam engine train piston would make the build a bit simpler, since it would require a motor to only spin in one direction (I’m not at all familiar with motors like this, but I’d guess that maybe it’s slightly cheaper, lighter, and smaller?), as opposed to having to move back and forth like the one you chose. Did you not think of this, or were there specific benefits to going with the design you ended up using?
I guess if you want to sync the recoil thing with the shooting then a servo gives you easier control without setting up additional encoders.
I would have used a DC motor with shape that pulls the barrel back fast then returns it slower.
the recommendation god have blessed me with a random tf2 video
RUclipsrs when they find out its not just tiktokers that can make a part 2
Now this... this is ENGINEERING at its finest.
Making all the Valve turrets...now you have to make a GE M134 Minigun from Left 4 Dead.
You could say it's very well *engineered*
i didnt expect what i got clicking on this video, it was really informative and cool!
yes i love this shit, im thinking about going into cad as a career. and i played tf2 for like 6 years. please make more
bro really said "that robot looks cool, Let's build it" 💀 ☠️
Good freaking god. That *is complicated*
The barrel recoil could've been easily achieved with a simple motor piston mechanism, no need for complex custom servo arms, just a wheel and stick.
you should use a airsoft either a electric one which would be easier but gass would make a smoke effect comeout the barrel
You should try and make it fit all into a toolbox like in the game.

It's here fellas, sentry coming up.
