can i replace the arduino pro mini with arduino nano and how

There is an error in the animation: the cage with the spheres should turn half speed!!!!!!! A grave error.

You could also test the efficiency of different materials

why my arduino work on the contrary??

Harmonic drive is kinda cool. Not entirely sure of its practical applications but the way it works, I'd not seen that before. With these tools and a driver board like arduino or r-pi you could set up a nifty Rube Goldberg machine or with many of them, do something like what Tim Hunkin does with janky but artful animatronics.

Finally someone explain that the capacitor is the key for changing the output state in the astable mode, other videos just throw formulas at your face and just skip the key of the thing with some "you just suppose to know that" vibes, what a shame. Appreciate it!

The Observation: Every charge freely pours out real EM energy in all directions, with no observable energy input. The Problem: Either the required nonobservable energy input must be identified or the energy conservation law is false. The Solution: The charge continuously absorbs virtual (subquantal) photon energy from the vacuum, coherently integrates it, and re-emits it as real observable photons.

Hello how do you build a faster sorter?

Great video, I learn a lot's. Do you think you can have 2 rheostat (one for speed and the other for travel distance) and make it a forward-backward motion?

Thank you! I tried following other tutorials that included strange libraries but this worked flawlessly. You're the best!

I really enjoyed this thank you. I'm guessing you could use 3 or even 4 colloidal disks to further strengthen, smooth and potentially reduce backlash. I'm curious how much slack comes from minor fit of stainless teeth and collets. Will be following and attempting to emulate your work, though you make CAD look so easy!

When comparing strengths you should divide by mass to get better results

hi R5: 10K?

How to made LED Name?

hi can you drop a link for the documents of omar

Wow that's some crazy 3d printing on those dowel pins and screws

Nicely explained, thanks.

I've made two of Mechatronics projects, the Mars Rover and the Scara Robot Arm. These projects are great because they are well thought out and designed, with lots of photos and construction details. Looking forward now to make one of these drives to learn about it and maybe use it in a different Scara robot arm. Good stuff Dejan! Thanks for this.

Precision is impressive , is it advisable to use it as a waist joint for a robot arm?

I am trying to build this. Doesn't work for me. The diagram show the pins on 2 and 4, realised code says 2 (3rd one along) and 5. But still not working. tried to adjust current but makes no difference. Exactly the same components 12v to motor but not have not added the capacitor. Any ideas please.

You need a test to measure torque while in motion so that you get the dynamic efficiency with parts in motion. Something like a disk brake (from a bicycle), similar to an engine dynometer. Or lifting weight with a rope and winch. The brake dynometer works very similar to your torque test, but the lever is coupled to the gearbox output shaft only through the friction of the disk brake.

You said “elephant tooth” instead of “elephant foot” intentionally to get reactions, didn’t you?😊

Can the MS1 and MS2 pins be controlled via software or only my connection to GND and 5V? I was working with TMC 2209 and was TOLD that such control was available on it,but later came to understand that on the TMC 2209 the MS1 and MS2 pins are used for setting up come parameter for UART control of the selection of Step type, e.g. WHole Steps, quarter steps, sixteenth steps etc. I really need to be able to control that via software.

I want to MIT App code and Arduino code of Robot Arm.. Hello sir i want to the Arduino Uno code of operating servo motors by mobile with the MIT app code also.

one clarification , you have stated that electric flux is the flow rate of electric field through a surface which becomes E/t

what ampere value of the power supply that recommended for nema 23 bro?

Your the best

Hello, these motors have encoder ?

Best video ever.

That's really freakin cool.

I tested a gearbox made up of Helical gears for the motor shaft and Double Helical gears, all printed in PLA. The gears moved a Step Feeder system, with low torque, for about 100 hours. I did not use any lubricant, and after this time the gears showed very little wear.

Where to buy

Helical and herringbone have less slack than straight gears.

Hi, pretty cool video. What about noise? I designed a two stage planetary gear (using herringbone gears) and it's very, very noisy, even with grease. Especially at high RPM. By design the cycloidal drive should be much quieter I think?

It's amazing until you realize all the strings are different lengths.

Hi Thank you for this great project. I am battling to get the app to work with robot. I see you have a updated app that is used when adding wheels. Will it be possible to send me the Code and the App details. Thank you

Great video, thank you

kinky

Very interesting & informative, many thanks.

Great video with intuitive and inspiring design. Would you like to specify which bearing to choose where the crank shaft contacts with the cycloidal disks? I do wonder rollers or balls might serve the role better)

I have subscribed but unable to use social media nor have a working laptop. I fixed vehicles for 40+ years and seem heater controls go from cable to all electronic. Today, for $10, I can have a 12Vdc electric motor that couples to a door. It directs air thru the heater core or around it. The dash controller is no more that a potentiometer to move from cold to warm, then hotter or full hot. I have the actuators that drive a pot using an internal gear. I am building an air distribution box for a 67 Chevy C10. You have fascinating devices but I was looking for something simple. I can scan your channels for a video but if you think of something that helps. Thank you!! DK. Retired. ASE Master tech.

Bevel gears and worm gears... where are those .. and talk about the backlash of each please..

Good video! Very thorough and helpful.

3D prints that need extra strength in a particular straight plane like gears, should be printed on a 10° angle/slope instead of flat on the bed.

Hello. How and where can I buy your complete project to print, assemble and program it for my needs?

I think it's pretty good. Remember that a car with mass ~1t have engine that provide ~150 Nm of torgue. You could probably create ultra leightweight cars for cities with small electric motors with 20 Nm of torgue and these plastic gears.
