- I designed, built, and programmed an Arduino powered hexapod from scratch over the last 3 months, and this video takes you through that journey!
For being my first robotics project in like 8 years, I think this turned out quite well :)
But there is still so much more to do. More gaits, better wire management, updated controller, additional sensors, and the release of the kit/course to name a few.

Obviously, we all want a tutorial! Srsly.
is that not what this is?
I demand a Tutorial!!!
Yes def
TUTORIAL!!!
I definitely would like one! I've always wanted to build one of these!
I started watching the video expecting to hear "I will be selling the plans", which despite how great this robot is, would be a heartbreaker for me. Hearing you say you intend to open source the vital stuff (code/3d files/instructions) while deciding to monetize the nice optional extras was just the sweetest music. I chose to subscribe immediately and will follow this project, and jump into building as soon as you feel the 3d parts are ready to share. You rock. Seriously.
Makes me really happy to hear this 🙂 Thank you 😊
(Also if you want to take an early look at the files email me and ill send them to you!)
@@AecertRoboticscan you plz share you email id
@@parthtailor1189 check my TH-cam homepage under about!
I agree. These kind of acts is what make human kind evolve.
@@AecertRoboticsHi, I am a student and this project seems interesting. Can I also have an early look at the files?
Very nice hexapod. Making it open source, with courses on top of it will help hobbyists or who get into it to just start building. I keep trying to find time outside software development to do some kind of robotics due to burnout, so know what you mean. Now we just need a few more of these and have them dance in sync for your own personal army of spiders :D
Thank you! And yeah I totally agree.
Omg that would be hilarious :D I can confirm I do plan on adding dance moves :)
@@AecertRobotics It would be cool to add programmable "patrol points" or "animations" (Edit: PRESETS) where you can record a certain movement to a button or two and tap it to play that specific animation. What I was thinking of specifically is that jump animation where instead of sliding the up and down really fast, you can record that to the motion recorder button and have it as a PRESET!!
Also, it would be easier to jump and spin, if thats possible, at the same time without having to use the slider!!
There are plenty OS heaxpods, one of the most common being the android.
I would purchase the course in a heartbeat! You’ve earned my subscription and look forward to further updates!
just found this channel and I'd take your course in a heart beat. I can learn so much online through various sources but there is such a benefit to a structured curriculum.
this is amazing and so beautifully done , cant wait to see the actual tutorial
Saw this on Reddit and I'm happy that TH-cam served this up. I appreciate all your documentation and instruction. Instant Sub from me!
Super glad you found my channel! Really appreciate the sub, there will be much more to come :)
Beautiful project! All the best!
well done , your progress and approach to this looks gr8 , subscribed , will defo be following this project
Interesting work. Here are some thoughts/ideas I had while watching:
1) Stabilization Muscles: Real-life joints have smaller stabilizer muscles in addition to the macro driver muscles. You might consider adding something along the lines of tensioned ligaments and/or little stabilizer drivers pulling on elastic, spring, pneumatics/hydraulics, or some equivalent tensioning straps across the joints. These could also help provide feedback data to help the system "understand" how the joint is moving by seeing which stabilizers are being tensioned and which ones are relaxed if they are hooked up to a force meter.
2) Force Redirectors: The knee joint, for example, has the kneecap, with muscles attached by ligament to the top and then separate muscles attached to the bottom. This re-directs force "over" the knee joint in such a way to reduce the torque necessary to extend the lower leg and also do so with more stability and less "jittering". That could also help with the "jitter/stutter" issue you're having with the joints.
3) Foot "Angle of Attack" During Walk Cycle: I noticed when showing the example animation for the walk cycle, the foot seemed to simply be "aimed" straight down and then the entire foreleg would slide backwards while perpendicular to the ground. I don't know if this was just for simplicity of animation of if it was actually how it's made to work in the code, but it might be helpful to give it a slight "angle of attack" when it walks; have the leg "tilted" slightly forward so that the tip of the foot points slightly backwards. In other words, the "curve" for the walk cycle shouldn't be a completely straight line, but it should attempt to "dig" ever so slightly down into the ground and there should be a "secondary" cycle for a point somewhere "up-leg", maybe at the middle or even at the "knee" joint with it's own walk cycle calculated just a split-second ahead of the foot. Maybe experiment with it to see if this yields any improvement.
4) Spider Curling: In real-life, Spiders have constant tension on their legs to make them "curl" up underneath them. In order to walk, they actually use their own blood pressure, forcing their circulatory fluid (not technically blood; in spiders it's called _hemolymph)_ out into their legs _against_ that baked-in curling pressure and then "letting up" or "pushing out" to operate the legs. It might be worthwhile to explore this as an option; make some kind of tension system that's constantly trying to fold the legs "under" and then the only real job of the servos is to "extend", and the variable is either "extend harder" or "extend less". It might even be possible to ditch the servo concept altogether, or at least re-purpose it and, instead, use some kind of pneumatic or hydraulic drive to handle the extension of the legs. BTW, this is why spiders curl up like that when they die; no more circulatory pressure means they can't fight against that forced leg curl anymore.
5) Ant GPT: Obviously not even _remotely_ something to implement anytime soon, but perhaps one could incorporate AI functions to do things like optimize leg movements, especially if it integrated aspects like the stabilizer "muscles" with sensors. An AI could take all the info like the tension of each ligament, angle of each joint, power of each servo, accelerometer, body orientation metrics, pneumatic system pressure, etc. and both coordinate the walking calculations and also continually work to optimize them. Hell, even incorporate _vision_ into the system by putting cameras on it. Give it six tiny cameras for good measure and also dramatic irony. They don't necessarily need to see "well", they just need "information" which can be incorporated and utilized for whatever it's worth.
Really cool ideas, ty for the comment!
3 I can and will try, I know exactly what you mean and I think it would help if I get it right.
4 is something I considered. I can do basically that by adding springs to pull the legs down, which would lighten the load on the servos. The more I think about it the more I think I should do it tbh.
5 believe it or not is something I plan on doing kinda. I want another hexapod project where it's walk cycle is completely designed by machine learning. It will have 4 legs, 2 motors in each leg, and I will train it in a simulation with a nueral net on walking forwards and turning. I think it would be a really cool project.
Hey man, I think this is seriously cool. Making mistakes is part of learning, and I've heard that one of the best ways to learn is with the intention to teach others. You've inspired me. Thank you.
Thanks dude :)
I completely agree! You gain a much better understanding of something when you have to teach it to someone else.
That is amazing!! Doing the modelling in blender blew my mind! I can feel the headaches of doing mechanical parts in it. But it's a great example of improvising with the available tools/knowledge.
Congratulations, this was extremely well done!
Thank you so much!! 🙂 Yeah it blew my mind too, but not in a good way 😂 I'm currently remaking the models in fusion360 and it is so much better.
Very true! if i wasnt comfortable in blender either i may have been too overwhelmed to even attempt this.
I am very excited for the course! 100% will get it the day it comes out. Loved the video and I totally want to build the robot because I am in college right now and I want to go into robotics so I really want to learn more about the course. Keep up the great work the video was awesome.
I'm so happy to hear that!! Thank you so much 🙂
Amazing project, the movement of the robot is so smooth. Congrats! If you can share the porjects as open source, it will be amazing!
Thank you so much! I 100% plan on it!
Can't wait for the course on this project
Kit+course idea sound really good
This is great! To me, I think I could create something similar, but that means I know how much effort was put into this project. Absolutely incredible!
This is great! I'd love to see a tutorial! Keep up the innovative content!
Brilliant idea! I like the kit idea Especially if you included all the parts and tutorial videos. My daughter is learning robotics and something like this would make a great gift.
Thank you so much!! That is exactly the plan, and I completely agree!
to see such artifact creature, brings me such joy that it kinda makes the sadness go away. Thank you!
I'd definitely be interested in a kit and a course! I've always wanted to learn more about these little robot projects and how to do them as a hobby.
I really like the idea of the course!
Yes! I want to print and build this. A tutorial and sharing code would be so amazing. Great job !
Hey Aecert, this is top tier content 👌. I've been looking to simulate something like this before actually purchasing the parts. Looks awesome.
Thank you so much :) Dude i regret not building this in a simulation beforehand tbh. Would you use ROS or do it from scratch?
I recognize this! I saw your update videos on reddit, and you even answered one of my questions that I asked you! Nice project
Thank you!! Im glad you found your way here 🙂
I love this! And yes I would buy both the kit and the lesson!
You got my sub from the sentence that ended 'in blender' :) Finally someone else that uses blender for precision modeling!
Love the idea of the course.
This looks like an incredible project I'm a robotics engineer myself and this is peak, would also loved if you would have talked a little about the dynamics of the robot not just the kinematics but it's awesome, hope that the kit and the course sell well the project deserves it.
Thank you so much! That means a ton coming from an actual robotics engineer 😊
What do you mean by "the dynamics" ?
Thank you, I really appreciate that ❤️
I need a tutorial so much!
Nice job!
OMG, it looks so smooth
I would def do the course if it comes out, I would love to learn how all this leg placement stuff works, as I'm currently building a robot arm which would really benefit from it. 10/10 channel btw.
Oh my God, please do it! I'm so hyped for the open source, the shop and the course! Your hexapod is amazing! I have a dream project to built a hexapod. I know a little bit of electronics, a little bit of arduino, have a 3d printer but I'm not an engineer. This course would help me out and it would be really great!
You are exactly the type of person the kit plus course is for 🙂 I can't wait for it's release!
Looking nice 👍 and good luck with your future project making it a kit with tutorials. Have fun!
Thank you so much man, I really appreciate it!! I definitely have been 😄
And this goes without saying, but your projects are amazing and an inspiration ❤️
This is awesome and needs more likes. I want a whole stock of these for when I want my mail brought to my room and for when I fight Spider-Man.
Amazing video! Deserves a lot more views for all the effort
Thank you so much! :)
Amazing work!
I would absolutely love a tutorial. I've been researching hexapods to build one with my sons.
Very cool project. Thank you for sharing your experiences.
Awww thats great 🙂 I can't wait to release the course!
Would 100% buy the course as you describe it.
Keep this up and this channel will get bigger
I like the idea!, looking forward :D
Excellent video, verry educational and beneficial to everyone.
Its happy jumps made me happy!
Can’t wait for that hopefully sooner
Awesome stuff bro
wow this is so cool! and the aesthetic of the 3d design too
Thank you so much! That was a very important consideration of mine when designing it.
I am in ! As long as the price is right. I am just starting in robotics. Bought a official Arduin starter kit. Thansk a lot. Give some stuff for free a get some money in return.... that is the way to go
Great work !
The moment i heard this is open source I subscribed. Need more people like you!
Sehr toll gemacht!!👍
it is really interesting, and im excited and waiting for tutorials 👉👈
Yes, tutorial and kit 👍
this video just got recommended to me and man, it's fantastic and the jumping surprised me. lol
also, i can totally relate with the burnout from web dev work.
I subscribd! This is crazy and epic! I am about to watch your next video
It´s look very awesome dude! Clap
Once I start my job in cybersecurity I'd gladly buy your kit and your course!
8:49 jumping hexapod is awesome
bro, deserved a sub
Currently a masters student in Robotics and I have to say your application of robotic kinematics and inverse kinematics to compute joint angles and actually develop the controls for your robot is so cool dude.
That means a lot man I really appreciate it 🙂
This is really damn cool. Well done!
Thank you so much!
I need the course
Excellent!
I really want to build one. it looks amazing ❤
Great project and implimentation. I'm looking to make a spider or hexpod robot soon. So it's great to get these hints on how you did it.
Thank you so much! That's awesome! If you have any specific questions don't hesitate to ask
Nice jump!!
love this project
What interesting motor skills! 🤔 like a real spider moved ! 👍
Great Work!
I like this channel already
This is really great. I do lots of 3dprinting but am now trying to learn electronics so I'd be very interested in the course.
Thanks! I feel like this would be a great project to learn on so im glad to hear that
Would definitely buy your course
I'm incredibly enthusiastic to see this project and to start robotics for myself after a long time procrastinating.
Hell yeah dude! Best time to start is right now 🙂
Yes, definitely want a tutorial. Need one better than the ant one.
YES! I'd love to see a tutorial; I would like to learn as well and possibly improve it!
Great build 👏,, Figuring out joint kinematics in this complex build in itself is the USP of this project and the upcoming course.
Thanks! Yeah thats a big reason why i chose this project, it was a really fun challenge. The key is to break the main problem (making a hexapod walk) up into smaller more manageable problems.
this is the most satisfying but terrfying also inspiring thing ive ever seen
Cool project, looking forward to the kit and course! A nice feature would be to get it running with ROS2. The benefit of this would be, if you put on some sensors like LIDAR, the hexapod would be able to walk autonomous and could use all the features of ROS2.
Thanks, and im really glad to hear that!
I 100% agree. Im gonna be honest, Im avoiding ROS atm because i know almost nothing about it, but I used it in college once and it seemed really complex and I had no idea what was going on, I was basically just following instructions and praying it worked.
But yeah I hear ya, it would add so many good things. Honestly learning the basics of ROS would be a solid addition to the course, but do you think it would end up being too complex/convoluted? The whole reason im using arduino is to make it as approachable as possible.
@@AecertRobotics yes ROS would be "the next level" as its quite complex to setup. You would also need a raspberry pi and sensors to run it. But if you have a working walk and steering system, i guess its easy to use it with ROS.
New robotics channel 🎉
"It jumps!"...lol, thumbs up earned. Great build
Thanks! 😄
you are KİNG , perfect job
Amazing!!!
This definitely reminds me of the spider bots or spider drones from Watchdogs: Legion
Holy shit dude it really does 😆
i would pay for that course. I'm subscribed and i hope to see that materialize soon
There should be a hexapod war competitino live streamed on ESPN.
Hey! this is awesome! I am a robotics engineering student and I must say you did a great job there. I will buy your course the day it comes out! please also include pcb design in the course. Thanks!
Thank you so much!! The course will cover everything 😉 (although I do plan on releasing a basic pcb tutorial on TH-cam)
Now add a terrifying 'gallop' mode :D
Reminds me of general grievous! So cool!
U got new sub!
You better scare some kids on Halloween with this thing. Great work!
That would be hilarious 😄
Great job, respect
I just got done building a quadruped one with the cheap sg90 servos and it's cool but wow yours is so smooth. I can't get much power out of mine without it shutting down. Definitely going to follow your project, thanks.
Thanks! Oooh great job! Im interested in trying to make a hexapod from mg90s at some point. It sounds either your battery is too weak, or a part of your electronics cant handle the amps required.
@@AecertRobotics I used a Arduino nano and a shield board, I'm guessing since it's being powered from one source is the culprit as I'm using a 7.4v 1300mah lipo and a buck converter to knock down the voltage to 5v, tried upping the voltage and it doesn't like going much higher than about 6v.
Very excited with your project. Good job! Very interested in the way you made that crab mode. Looks realy beatiful (thought first that this looks kinda like procedural one :D). Have built similar walking platform with rotating turret, but really struggling with dynamics coding
Thank you so much :) Yeah crab mode turned out wonderfully tbh. Its basically just the walking straight code, but then I rotate the generated points based on where the joystick is pointing. Omg a turret :D I want to add an arm ontop of this thing I think it would be sick.
@@AecertRobotics oh yeah, manipulator on top of this wonderful creature is also very fun idea :D
Ye, about the turret: i watched a lot of videos about modern IFVs and APCs and made a turret first (smth mixed between bradley and russian bmpt’s) and then i looked where can i mount it. Then i watched a trailer of Armored Core VI, so i decided that perfect place will be a walking robot :D
Lmao that is awesome. You should post a video of it!
Amazing project!
It's nice to see a tutorial about this robot. In my opinion, it's much more interesting to observe the code and mathematics principles of hexapod in video format (not for free, of course). I mean, to make paid video course with explanation of principles of walking, moving, and etc.
Good luck😁👍🔥
Thank you!! And I totally agree. I havent put too much thought into it yet, but I do know the course will definitely have a ton of videos! Thanks lmao ill need it 😂
This is sick. You definitely should do some tutorials
plz make a video about kinematic and dynamic of that robot , realy great job
This is really cool! You also might be able to get rid of the jittering legs by adding a pid controller for the motors, but honestly the friction plates are a lot less work and perform fine.
Thank you! Yeah i tried pretty much everything except a dedicated servo controller board, but im trying really hard to avoid adding complexity to the electronics unless necessary. But honestly I should try a servo controller combined with a more powerful arduino mega replacement, because it might be a lot less complicated than I think.
@@AecertRobotics If you have enough I/O pins, servo controllers are just unneeded complexity. I don't understand why so many people use them.
The jitter is a mechanical issue. A "pid controller" isn't going to fix them.
My biggest complaint about most servos is they use potentiometers. Potentiometers in robot projects are a bad idea. Potentiometers wear out over time. I'd love to find a cheap way to add hall sensors to servos.
Yep a tutorial would be awsome!!!
yes i need a tutorial its amazing
This is legendary!! lol
I am also really interested in the open source, kit and courses!! 😊
