*FAQ: Such a huge project makes it impossible to cover everything in one video, so here's a bit more information about why we did things the way we did!*
- The biggest challenge in this project was integrating and tuning our system, because big hydraulics, heavy frames, and tons of sensors have a lot of variability that needs to be checked. We used an open-source hexapod library to control how it walks, which has been used on much smaller hexarobots, and works great. Once the mechanical system is more reliable, it will be able to walk easily.
- A lot of people asked why we didn't make a scale model, and the answer is quite simple. When you get to multi-ton mechs, scale models provide almost no benefit, because you can't build a scale model the same way you have to build a giant steel machine. A toy version using motors wouldn't teach us anything. And if we built a 1/4 or 1/2 scale version, the cost would almost be the same as the full-size megahex -- because all the components required cost approximately the same, small or large (valves, sensors, even hydraulic cylinders don't change -too- much in size).
- This leads into another common fallacy when it comes to science fiction -- Movies like Transformers, or Pacific Rim... simply aren't possible. Doesn't matter how far technology advances, when you get to literal skyscraper sized robots... there's not any materials on earth strong enough to withstand the forces of such a big mech! Everyone's familiar with the common saying "The Bigger They Are, The Harder They Fall". And that really sums it up. Why is it you can drop a cat from a few stories up and it's fine, but it's certain death for humans? Because force multiplies with mass.
- Why flat feet? We had planned on designing different feet attachments for it (you can see the holes in the plates for mounting), but for the base foot, we went with a large flat foot with rubber pads on the bottom, as the initial goal is just walking on flat ground. Having a big flat foot helps ensure the foot remains parallel to the frame, and the leg perpendicular to the ground. A pointy or rounded foot would increase the risk of the robot "twisting it's ankle" which is the weakest link in the excavators. They aren't designed for angular forces.
- Why didn't we do more FEA calculations? FEA calculations are great, but sometimes are just theoretical for best-case scenarios. For the excavators, we didn't design or manufacture them, which makes them an unknown variable that makes it really hard to calculate things for!
- Are we going to revisit it? *yes* but it might be a while. We want at the very minimum for it to be able to stand up on display, and walk one leg at a time (the slowest, but most stable hexapod gait)
That's really cool. I'm glad you guys stuck with it, I'm sure it was really hard. And thanks for the FAQ!
Ty for faq
I’m not 100% sold on the idea that larger ‘mechs are “impossible” due to the force multiplication of their immense weight. It’s really a matter of current materials research not being on par with the physical requirements of such a colossal machine.
That being said, even IF we had the materials and technology to build such machines, you’re still putting up a MASSIVE target in a combat environment with significant stability challenges. And then firing massive weapons from said platform. It’s just downright infeasible in any theoretical combat environment we’ve ever devised.
How are you guys doing? Dont forgot to take care of you both your mentle and physicale health guy good luck and thank for your hard work

I am studying Robotics and I am blown away by how far you were able to get with this thing. I was implementing a closed loop walking algorithm for Hexapod as part of my thesis and I know how hard it is in simulation let alone irl. You have my biggest respect. I hope people will see how much time and love is needed for things around us to work robustly. Thank you for what you are doing.

The sheer amount of dedication, resilience, and tenacity this took was remarkable. It's always painful when the idea in your head takes longer than anticipated. But have to say, the result is one of a kind. Your team pretty much did the impossible! I love the result, or at least the result that was temporary!
thank you! it was quite the journey
@@theHacksmith yes, it most certainly was. We put a piece of ourselves into every project, and the project leaves of little piece of itself, in our hearts. Even on unsuccessful projects.

Except there's a guy called Matt Denton that goes on tour with the rideable hexapod that he made over a decade ago. So this isn't exactly unheard of. It's just a rehash of someone else's work.
As an engineering student myself it was really awesome seeing you guys highlight not just the successes, but the learning opportunities too! I loved having Bogdan walk us through the thought process and emotions at each step, as it gives us a very valuable insight into what truly goes into these videos. Personally this is probably my favourite video you guys have done, kudos to everyone involved! I hope you do more of these mini documentary-style videos instead of the flashier reaction-based videos, so long as they're fun for you guys to produce as well :-)
Small side note, seeing you guys just dragging it back and forth on the concrete like that made me laugh as much as it made me grimace 😂
Even the biggest failures can be a road to success

Its always interesting to watch this and see what different decisions on parts or configuration could be to improve outcomes, but really impressive the amount of engineering and troubleshooting. Thank you for sharing!!

The level of ambition and ingenuity is off the charts on this one boys. You successfully made a Giant freakin' walking spider-mech prototype! It's mega frustrating when budget and labour constraints inhibit a passion project like this, but your team must have gained a ton of valuable data on things to avoid in the future.
It's the definition of grit. When you get kicked down, and you keep on going. Over and over. Absolutely incredible
Let's be honest. When I first saw the little thumbnail and read the title, I was sure it was some kind of CGI showcase. But no, you guys actually built a huge spider mech and walked with it. My words can't describe how blown away I am. Crazy good work!
You can climb a mountain with this
Have you seen their channel before? Get used to it if you haven’t…
Please, you must have been watching Wild Wild West to think this is CG....
This is just so incredibly complex... I can't believe what a smart and talented group you guys are! You need to work for NASA!!
6 separate engines running 6 arms with completly different movement profiles? No thanks.
Y'all get mad props for attempting that. Keep it up guys. & happy new year 🎉
I actually really like the fact that you're ok with showing how a project failed, because not only is it a very interesting story on its own, but it also gives us a great look at what working on stuff like this is really like. The fact that no project is guaranteed success makes the ones that do succeed all the more impressive.
LOL They have no choice. They need to get some kind of revenue from it.

@@mkisner8060 Yes. Obviously making money is part of the reason they uploaded this, but that's true for any of their videos. It doesn't change the fact that the concept of a documentary style video showing how a project failed is interesting and novel.

if you get anywhere close to that i think it would be an achievement for anyone. thats not giving up actually. its just stopping. time money etc. they actually taught they can do it easy hehe.

정말 대단하시네요.. 제발 좋은곳에 사용 됬으면 좋겠어요.
This and your Bucky arm design has inspired me to start studying robotics and biotech to try to create some amazing things thank you
We learn the most from our failures. The fact that it was able to walk and turn is a feat of engineering that you guys should be proud of. You figured out how to make it move steadily, adjusted things as needed and over-all made a very solid platform. We won't be seeing mechs anytime soon, but taking little steps like this are a great way forward.
As much as I would love to see you guys make a working 6-legged mech, don't kill yourselves over it. Do what you can and keep testing. Isn't that the entire point of the Scientific Method?
An 6 legged mech that could work a bit better would be trying to make another OSU adaptive suspension vehicle , that one is a rather old mech that was hydraulic but it could go to up 30° degree inclines , "run" at 12 kmh , carry an operator and 200 kg of payload , that mech was finished in the 80' so i think a modernized versión could work the same or better
I am really saddened that this project was put to rest even if it had the real potential of becoming something so much bigger... But I suppose I shouldn't request too much. The fact that the Megahex project carried out this far to begin with is a miracle of its own, and the fact that ya'll cared this much about your passion project that you were working on it despite it making you loose money, to the point that it almost pushed you to bankruptcy... That's wholesome, man! An inspiration to all the aspiring engineers or any other artists at that matter, and a textbook definition of ''Step by step goes a long way.''
I wonder if it would be possible to make it completely analog. Like rather than computer programing to make the legs move just right, it maybe could theoretically be possible to have that all controlled by a gearbox, and the 'pilot' could control the direction with a stick connected to the gears?
@@-jank-willson that would be so much stress that it'll probably snap instantly
I believe that in order for the machine to move naturally and smoothly...we must return to nature and place sensors on the spider’s feet while walking in order to measure the movement of its limbs compared to its abdomen and measure the rise and fall between the legs to discover the correct matrix for the correct walk.
Just by watching the video and seeing how it works, there are a few changes I would have made. The first is the transportation - by dragging the legs, it would have added more stress to the frame than was needed. If the femur was raised vertical and the other segments folded in, then it could have been rolled out much easier. The second thing is the feet. Rather than have them digging into the ground like that, I would have allowed them to articulate / rotate using heavy duty springs (Side effect would have been added stability). The final thing would have been to watch high FPS videos and motion capture data for spiders moving and use that mocap data to "animate" the walking.
To be honest, as an engineer I watched this from the beginning to the end since the video format was quite good, and another reason to support you on a project like this one since I know how hard it could be.

Hopefully way down the line this project can be revisited. But this is definitely a lesson in asking and understanding the important questions before beginning building. Shear stress during turns was definitely something that was majorly underestimated!
Don’t let this failure take away from what you built and how close you came to success! We’re all proud of how far this team has come and how ambitious they remain!
I'm a machinist, and while I'm not familiar with creating accurate stress analysis reports, some simple math, and individual destructive testing of critical points to confirm the stress analysis they did do, could have at least proofed out the concept.

Without a doubt, these projects mark a mark in the history of civilization. Congratulations! 🐾👏👏👏👏👏
building something like this requires expertise in different fields, specially automotive industry.
but here is a few key things i noticed:
I noticed you are making this machine unnecessarily heavy. and when something is heavy you need more power for it , and hence it will make it even heavier and when its heavier?
yes ! you need to make up for the joints to be stronger and that will make it even Heavier!
and when its heavier its harder to balance in 3 legs that are not versatile at all .
spider legs are super sticky and and versatile
if you could simplify it and make a super lightweight version , it would eliminate most of the problems
Your team did an incredible job with this. It's amazing to see a CZcams team go at these major projects that seem so advanced, that you'd only expect major government-funded corporations throwing millions of dollars to develop. Very well done
Oh the gov id making even crazier things they just dont show it to the public
@@Unkn0.n Yes, government crazier things is to how spend all these tons of money for nothing and keep draining them like everything is ok. Only such enthusiasts like Hacksmith industries and others around the world can spend money in proper way. Just because they spend their own money on their own ideas.
Y'all this thing is a childhood dream come to life! I cannot imagine how much time the team combined sunk into this project, but I think it's totally worth it. At the very least, you can show it off as a non-moving statue in (or near) the showroom.
Do we think it's time to revisit the spy car series?
that would be cool, yes. maybe try and give the spy car retractable shields, just came up with that one on the spot but I'm sure you could do something much cooler with it
I'm hoping people continue this technology. Its coolness factor is off the charts.

Yes... That's what a people's genius is capable of if you don't interfere with it. I sincerely admire it, I must admit, until recently I was sure that the preview was just a photoshop, or at best a “dream” image.
Unfortunately, here in Russia we do not have such large-scale projects. There is not enough money.
But there are still a couple of impressive ones:
1) A guy in a garage is assembling Tony Stark's costume. And no, not just a piece of metal. He already has a kind of reactor in his chest, a laser repulsor (burns through 1-1.5 mm of metal) and, most amazingly, artificial muscles connected to nerve sensors!
2) Our students created the world's first (at least known to me) macholet. Those. a thing that flies by moving its wings. It looks like a three-meter dragonfly) There is a video of the launch on CZcams.
3) Well, this is not only in Russia, but I saw how people, mostly grandfathers, flew on homemade helicopters and airplanes.
It's a shame that such geniuses often remain forever only people's Kulibins (that's what we call them, in honor of the people's engineer of the Russian Empire).
As an engineering student (that has a control theory exam in 2 days), I couldn't ask for a better motivation boost than this video. Being familiar with the subject gives perspective on the immense complexity and scale of this project it truly is insane! So much respect for the team!
Awesome video. I would love to see a detailed breakdown of the software side of this project. This was obviously a huge undertaking to export the model from Solidworks (URDF?), to then manage the joint locations so you could get the nice real-time graphics in RViz and feedback to help config your PID controllers. Awesome job all around, really showed how difficult integration of robotics systems can be.
This just gives me that much more respect for the Factorio devs when they created the Spidertron. Granted you don't have to deal with physical and structural limitations in a video game, but just the control logic by itself is impressive.
@@DFPercush same here
@@DFPercush Not trying to undermine the Factorio devs as they have done some amazing work, but admittedly writing the code for a video-game hex-walker type thing is really not very difficult. I say this as a professional software developer who has spent a lot of hobbyist time working in game dev/studying the kinda math that's used to do this stuff. Let me explain further, though so I don't come across as a 'WELL ACKSHUALLY' type asshole lol (sorry if I still do!!):
What makes making something like this so insanely difficult (specifically the thing in the video) is as you mentioned the fact that your computer model needs to PERFECTLY match the real world object. That means EVERYTHING needs to be made within incredibly precises parameters. Then on top of that, your sensors need to be incredibly accurate. They can't have any slippage, they can't drift, they can't be noisy.
And then even further you need to account for all kinds of mechanical processes in the software that only begin to emerge after testing. For example, the legs flexing under load/stress but not while idled. The feet bending after heavy hits, the sensors slipping due to a sudden unexpected load, etc.
In the world of a video game, ALL of that is gone. Making a little spider mech in a video game is genuinely high school level geometry and algebra (for the most part).
As a final clarification, I'm not downplaying the Factorio devs. The work they've done to optimize that game to make it run so well, is truly incredible. The amount of shit that's happening in the game every frame is obscene, and to have that all work so smoothly and cleanly is fantastic. I think that's where the admiration should be given, they have quite a few dev blogs written about how they got conveyor belts working (efficiently) for example lol.
Also, in case you want 'proof' read about Inverse Kinematics. It's exactly how you accomplish this type of thing. It's the field of math devoted to "I have a robotic arm and it needs to put it's 'hand' here. What angles do all of the joints need to be?". It's an incredibly powerful and fascinating area of math!
Anyway, I hope I'm not coming across as an ass here. This is an area of math/engineering I am personally very passionate about so I just love to talk about it!
Looks like ROS2 to me
They used the "KevinOchs/hexapod_ros" repository as a base.
You guys are super smart! You did a great job.
I'm half way through and I'm just thinking how much I'd love to be programming something like this walking motion as a fan of programming (my day job) and geometry. Moving the foot in a straight line means moving all 4 hydraulics of the leg as well as the pivoting of the femur at varying speeds depending on their individual positions. Oh the fun of doing that!
This will be my very first donation to anyone ever on any platform, but feel like this is the right time to show my thanks in your time of need as a thank you for inspiring me to pursue a career in engineering. Thanks Hacksmith!!!
That's only 5 bucks 😂
@@andrewfullington9777 hey ! everyone donates what they can! we cant all have the same job in this life so some will earn more than others, respect those who dont earn as much as you are suggesting that you earn.
@@andrewfullington9777 how much did you donate?
@@andrewfullington9777 5 more than you lmao
i cant believe how far this channel has come. i've been a sub for nearly 6 years now and i remember when strapping jets to james's arms was a crazy thing to see. now we're at something as intricate as this? holy crap dude, i cannot even fathom the time, thought, and money that went into this. this channel is one of a kind
anyone who would make a video like this would get 2m views minimum. you know how much this video costs?? this is not the best yt model.

No abandonen este proyecto será super crucial para el futuro con el tiempo y esfuerzo lo lograrán
I think 100% you successfully proved this was possible
I am a retired engineer from one of the major automobile companies. I spent an equal amount of time in product testing and software design over a 30-year period. There is NO better way to learn than through application. No book will ever teach you all that you learned by doing this project. I have a BSEE and that got me into a company and started with the basics, but it wasn't until I was in the field that my real education started. I can not begin to tell you how amazed I am that you got as far as you did. There are SO many variables to consider. You guys are absolutely amazing and exactly what engineering is about. Do NOT be disappointed in the fact that the frame didn't stand up to durability testing (which is what you ultimately did when trying to figure out how to get it to function). All of those who worked on this project represent who we need driving to a better and more interesting life. Keep up the great work!!
Absolutely incredible. I couldn't believe what I was seeing even just 3 minutes in, let alone the end result
Your £5.00 is going directly into the our fire pit!
Thanks for your support! lol

It's looks like money! It's smells like money! It's tastes like money! It's MONEY!
Absolutely bonkers, and I hope this video has done well enough to recoup at least some of the crazy costs!
Very cool guys. Lots of hard work and a lot of accomplishments. Keep it up
Thanks for full sending the craziest builds around, stay strong and carry on! This was EPIC!!!!

The pain and joy of working on a project and seeing the successes and failures is something I can really relate to.
You guys should be insanely proud of the effort around this project. Seeing that first rise gave me goosebumps!
Awesome work lads! Keen to see more content (success or failure) :)

Raiden: Armstrong, impressive little toy you got there!
You guys were literally on the cusp of success. Do not give up!
We weren't though... mechanically it has a lot of problems
What’s also super impressive is that they had the patience and confidence to keep this project quiet for a year an a half
Blown away by how much was acconplished and you guys deserve a ton of props for both perservering and knowing when to stop
so true
Subtract many props for deciding to transport the machine by dragging it over the ground.
@@amarissimus29 lol true, cringed every time i sae that one leg just dragging and kicking
LOVE THIS! Been following you guys for a while and this is like the coolest. I'm thinking maybe redesigning the feet would give it a lot better grip and keep it from sliding around as much? Since metal and flat surface usually makes for really poor grip
Wow, impressive build !!
I am in awe of the wild and wacky projects you've managed to pull off! I don't know how you do it, but keep it up, because you're making the world a more interesting place one project at a time.
Money!
"Failures are the pillars to succes ."
The hardworking, dedication, efforts , minds all are the products coupled with luck and engineering has finally paid of . Not saying this whole so sick project was a walk in the park , but the final product was worth it . Hacksmith industry guy , you guys are awesome. Enjoy it man . Spider mech is crawling baby !
Sometimes we learn more through trial and failure than we do from out right succeeding.
"Walk in the park"
Pun and futuristic reality in one go. Noice!
Led me to think
man this is the youtube for . hats off you and your team . from india .
