Excellent work.

I think you can make it more efficient next time.

Amazing work! Maybe a global shutter camera would be better for the bouncing ball test.

This seems like a MIT project? Is there a step by step software/hardware learning kit with several videos? 🥂 Thank you for the great info.

its a shame its an AI voice, other than that video is real nice

Such a wellmade video! Can you help me solving the kinematics of my SPM? 😊

great work!

My god this is awesome!!! ❤

i saw the blood on your hands hope they are okay now

Hey dude! Looks awesome! I have made the exact same thing! (There’s a video on my channel of me testing it with an ESC. 2 ways to fix your rotor issue; there’s some serious magnetic forces there, so if your rotor is thin, it could easily flex. Even if it’s made of metal. Try thickening the wall of the rotor. Even .3mm of flex can cause issues. Another way is to actually constrain the rotor from the back as well. Having a bearing at the back greatly helped mine. Now, 3 questions. Size, weight, and cost? Mine is 110mm in diameter by 44mm thick and weighs 700g. Overall it cost about 90$ per actuator. Curious what your specs are.

would love to see make a rover with a rocker boogie suspension system

really impressive content i am curious though what did you major in university

love your work, keep it up.

Aight this might be the first text-to-speech video I saw that had good content. Don't really know how to think about it. For now I'll just assume you don't know English that well, cause the rest of the video was still very high effort.

Try with chatgpt

I don't think I will ever not hate AI voiceovers. It just makes the whole video feel fake and clickbaity. I would prefer text on the screen over AI voiceovers.

May I point you to another lesser known type of reducer - wave drive w\ rolling elements: ruclips.net/video/zOLQw-TxE7s/видео.html ruclips.net/video/c73QGWpfhQw/видео.html

felt like i am seeing aed musa in thumbnail :)

You should use pins for the bearings if possible, otherwise impacts could wear down the screws and make the bearings loose

6:50 Philips screws🤮🤮 Use hex or torx please

Just take an idea out of my mind 😜 Nice to see this already happen 👍👍👍

Cool design! I wondered what max phase current, phase resistance, and KV this motor has. I am also working on FOC actuator now, but it's a low-torque, much smaller, and direct drive. I guess you are planning to use a magnetic encoder in the middle of your board and use sensored FOC, right? Are you going to write it yourself or use SimpleFOC or similar? That's a lot of work ahead! Keep crushing!

cool!

👍👍👍

7:20 if you have a 3d printer, you can easily design some rig to hold a motor while it is assembled. So, you will not have a problem with falling out screws.

Interesting to see J.L.C.P.C.B/3.D.P sponsoring many channels using AI-generated voices, their brand name is almost always spelled the same way.

Nice vid, but would be cooler to hear your voice rather than AI narration.

nice man

big if true

6:03 but where did you get the stator?

Thanks man im subscribed Are you going to dive in to Isaac sim?

Excellent! Awesome! Great! I'm looking out for the next video!!!

Good work. Thank you for sharing even though it wasn't perfectly centered yet. Important work. Looking forward to the next iteration. Where did you get the stator? - I hope some day there will be a parts list, kit, or order-ready manufacturing whatnot from some provider; and not too expensive. :)

James Bruton made a very similar cycloidal gearbox for his OpenDog v3 platform, there may be some lessons in his video to help. Looks like the big difference with his is a second bearing race to keep the output centered, which should help reduce the rubbing and increase the resistance to bending torque. Right now any load that would bend the axle is only being resisted by a single bearing race. Putting any leg on the output would induce a bending moment that would almost certainly crash the rotor into the stator even if you get it otherwise centered. The good news is with this design you don't need the giant race James had, you can just put a small race on the other end of the central shaft, with some spokes to the housing.

Looks great, neat design with the cycloidal drive inside the stator! In my armchair-based opinion I think you only need to redesign the shaft, the other components fit together nicely and the rotor is just rotating off-center. Maybe use a stronger material? Also, please wash your hands before recording shots, it looks like you just killed someone😂

Thank you

Hello, Is there a subsitute for the futaba motor. It is quite expensive. Thank you

these are dubbed videos?

Sir what filament material did you used?

Excellent meticulous execution - a pleasure to watch someone how knows more than myself 🙂🙏 I can't wait to watch your take on the cycloidal gear + brushless motor. I've seen the only one on RUclips some time ago, but it was not meticulous execution, quite good nevertheless solving the fundamental problem. I guess the problem with regular cheap servos are (3 pins: GND, +5VDC, PWM), that there is no position information. Therefore, you cannot control the acceleration in relation to setpoint. Also, I'd like to see more channels (for the whole robot) with the same controller; i2c has address capacity and STM32 too (I assume). But maybe the the power is not enough. Thank you for your interesting efforts and good luck. Greetings from Finland. Subscribed with All 🦾😊🙏

Nice work! It would be interesting to see a really top-quality servo that not only replaces the controller, but also substitutes an optical quadrature encoder for the potentiometer.

You can save a bit of money on the voltage reference, one is not needed at all, the measurement can be performed fully ratio metrically so absolute voltage error doesn't affect the measurement. Most stm32 parts can do this

Very cool

Excellent work! Thanks for sharing! I'm using the same servos(RS304MD) for one of my projects. I wonder for multiple servo control, did you use the "TB-RV71EH" and the "TB-22PP Hub" as shown in the RS304MD Instruction Manual for this robot? I didn't seem to see them in this video though.

Twenty eight years ago I was an engineering student. I graduated and became a licensed engineer. I've always wished I "learned" math and not just the mechanics of math. A project like this would have aided my learning, knowledge retention, and abilities as an engineer. 🍻

Smart. Elegant. Engineering. | Subbed. Do you have products in production?

Thanks

Very nice, I'm also have simliar idea, but it was too crazy to do it (dissasembling cheap part and addig to it more expensive controller). Did you consider adding CAN interface to it? It would be very helpful in my TVC drone project

Awesome 👏 This is what I been thinking last week 😂 I don’t know how to design pcb, even for a normal size MG965 I can’t squeeze the mcu, motor driver and encoder all into that small space. Thanks for sharing your awesome project.❤
