@@AaedMusa ⚠️ God has said in the Quran: 🔵 { O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 ) 🔴 [He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 ) 🔵 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 ) 🔴 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 ) 🔵 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 ) ⚠️ Quran
Lithium grease is for high temperatures, it can soften pla and dissolve plastics over time, i figure silicone grease is cool for pla. awesome info i hadn't seen that thanks.
I'm a young student moving on to post secondary study soon and I am grateful that you were able to share this video! I am working on some of my own robotic projects and I have always had a hard time finding ways to control brushless motors and so I have stuck to brushed to simplify things for myself. After watching this you have taught me enough to inspire me to go back and learn more about his brushless motor control! I appreciate this and you definitely got a sub from me!
Really impressive. Video is super clear. Looking at the rest of the project looks like a really solid design that can be adapted to other projects. Thanks for sharing. You already have me pricing out those motors online
This is a really well done project, and an amazingly well done video. You are a natural at presenting your material with a touch of humor and a ton of knowledge - well done indeed!
Wow, that's pretty neat! If you make a video on a walking robot, I can't wait to see it. Your website is pretty dope to get more info and the design from. Top notch creater that deserves more attention. I've heard of those brushless drone motor catching fire becasue usually they are meant to have air blowing constantly through it, but it can be managed hopefully. Cheers!
Thanks! Hopefully, that won't be an issue with the current and velocity limits but putting a small fan on the inside could be a potential upgrade in a future iteration.
@@AaedMusa With those vents I can see using a small temperature sensor and one of those super small aliexpress 12v pc fans to actively cool it if it starts to overheat. Also, production value is 🤌keep it up!
@andycrask3531 Yes, it's a great channel. I've been subbed to him for a few years. I like this actuator better than the cycloidal drive actuator that James Bruton build for his walking dog because it's much smaller with the motor assembly and everything as well as having fewer barrings which can jack up the cost a lot very quickly.

Pounds? What's that? Why do they still insist on using outdated measurements instead of adopting the universally accepted metric system? The international scientific community has embraced the metric system for its precision, simplicity, and ease of conversion. Transitioning to the metric system would not only promote global consistency but also facilitate cross-border collaboration, facilitate trade, and enhance scientific communication. It's time to leave behind archaic measurement units and embrace a standardized system that promotes accuracy and efficiency on a global scale. ps: Liked and subscribed.
Very cool. I have found that inexpensive force gauges from amazon are pretty good and useful for measuring things like this, they come with different attachments and mounting options, some of them have serial ports for data logging.
was fully expecting this channel to have like 100k subscribers when i looked at the channel, this is a very well made video and a very good actuator design.
Wow, excellent project and awesome video! Great editing and videography, impressively artful editing, and well thought out explanation of enough of the basics to explain your design decisions. Love it, excited to see what you build with it, and if I can finish some of my current projects I'm going to build one!
Great video. I would suggest you use a vice for press fitting things rather than a hammer, a vice let’s things go in straighter without any impacts. I would also suggest using nylon for the gears if you are able to print it. Edit: you should also stop mixing units, you measured the arm length in inches and then calculated torque in Nm. NASA made a mistake once due to mixing units and ended up destroying a probe.
I noticed one thing wrong with your 3D printer you may want to consider fixing. Your bed looks loose from the clip at 2:03 underneath the bed there should be eccentric nuts, tighten them until it doesn't wobble. Look up a video on how to tighten it for further instructions.
Thanks! Also, having the clamps on one side made my eye twitch. Those tests aren't providing enough data about the motor without a stationary point. Make your base wider, Flip the clamps 90 and add a few milimeters between, then reposition the camera. Anyways, I'll be using this within my engineering courses this fall. Thanks again for all you do! Would you be interested in meeting virtually with my students, this fall?
It appears that the algorithm is blessing us all with your fabulous content! I’m very excited to see the continuation of this project. It is beautiful work, and presented wonderfully. Subbed immediately.
1. A robot that goes to the store, picks up the products, pays, and comes back to you. 😃 2. Use large language models [llama, chatgpt] as modules of different parts of the architecture. Tasks on the higher level, implementing them a bit lower etc. This would be my way to go about it, but I don't have the robot 🙂
I'll be joining the boilermaker crew as an engineering student in the fall! This is crazy awesome, cant wait to see it being implemented in some robot designs. I hope one day my videos can be as impressive and entertaining as yours!
Great performance for sure. It appear to me that a more versatile walking robot should be built with 4 motorized wheels as feet. This way the robot becomes much more efficient as it can walk and or roll.
Awesome job dude, just think how nice this will be if It was printed from a high quality UPAHT-CF15 or a PA11-CF instead of PLA, even ABS-CF would be a nice choice.
if you continue like this, i see no reason why you shouldnt succeed, really entertaining video! Nice explanations :) Keep on going, good work. Greetings from Luxembourg
THANK you so much for making this, I've had a project on hold waiting for just something like this! I want to make a gang of these to pull and feed out cables in a cable operated robotic mechanism. Excellent work! I'd love to see you make a bipedal robot, use the technique of simulating the actuators in a game engine like unity, and train the control AI in a game engine on a desktop PC. (That is the part I'm focusing on, how to simulate cable mechanisms in a game engine, and use that to train a control AI)
Awesome! I just finished making a cycloidal drive actuator! I am using nema 17, but i love the idea of using BLDC, with my terribly inefficient nema 17s,
@@AaedMusa yes, I am a little noob on the electronics, just getting comfortable so, i was not gonna get into position control and all 😅 But yes, I will get into BLDCs
you went with an expensive motor, gave up on the cycloidal gearbox, and just used an Odrive, which makes this project equivalent to James Bruton's design (or worse, since he at least used a cool gearbox
Please use the Metric System. Only three countries in the world (out of more than 200 countries) use the imperial system. Only three countries resist using the system that the whole world uses.
Dude. This is such an inspiration to me. I'm in my third year of mechanical engineering and I'm planning on going to grad school after I graduate to further study robotics. I have been teaching myself arduino and super basic robotics stuff in between classes in my free time but I have such a long way to go. It is so motivating and inspiring seeing what this field can do when you put the time into it. I would love to know what your education path was like. Did you attend a 4 year university? Graduate school? Self taught? Is this a side hobby or a full time career you have? Thank you!
Awesome content man! Looking forward to your next iteration of robot quadruped using this drive! Side question, would you continue making content for your channel after graduating?
this is awesome man! but this bed adehision is incredible. I just wanted to give you an advice about that, if you just hit the bed where it is, you are gonna destroy your bed level and also in the long run you can ruin the printer itself. with my cr-10 when it is really stuck there i remove the bed and i place it on a desk to scrape or bang it off. if you want to just pop the things of the printer it is really nice to have a glass or mirror bed with some hair spray on it or you can just higher up the Z-offset. i hope you find that helpful ;)
i think going from a 3d printed actuator to a entire walking robot is a big step and would take a really long time maybe make one leg and then for the next video make a whole robot?
Enjoyed the video, but I think I found a flaw in your logic about robot domination. If the actuators are compliant, then the robot will be compliant and therefore no desire to take over the world I'll get me coat
Awesome video, great project, and I especially enjoyed the great editing with all the music and sound effects! Instant sub and waiting for more (after I've watched all of your previous videos).
