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.

Hi, I made a wire bending machine with my friends for a school project. We have a problem when we connect all the motors, only the one connected to the bender works, the others don't. When we connect the other two motors to that input, they work. Can you help us because we can't figure out what the problem is

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.

2:21 "coDU-c/Tors" 4:17 "o-NE" 5:35 "M/Ake" 5:55 "M-o-Vment" 6:06 "wIR-e"

Do you sell these in a kit ready to assemble with all the parts?

Did someone ended making a more stable frame for that machine?I would love to build it but I'm not good at all in using a 3D software to create the required parts.

Gray gears holes/bolts are loose. Use larger width?

observing the failure modes of the printed gears was interesting. it seemed like the failure was primarily happening either Wall-Wall or Wall-Infill. I wonder if minor filament under extrusion can lead to weaker wall-wall bonding. I don't like the use of the horizontal expansion setting personally. I think it is better to explicitly model allowance into the printed part before slicing.

Thank you for the diagram.🙏

@07:30 it's impossible for a perfect print . The key is post print processing . File the rough edges down . Àlteratively , you can increase the bottom and top later thickness and sand down the base and top by a little amount to take away any issues .

Try the same test with "mechanical", or iron gears!

holy cow, thank you so much for this video. So much information presented so clearly :D

Great analysis! For more strength print more (4-6) shells/perimeters and top and bottom layers (4-6), consider internal planar structures for additional interior wall strength. Printing hotter and slower improves layer adhesion and strength. Fixturing is important for the strength tests. As you pointed out, supporting the axle on both sides to prevent deflection and ensuring the lever force is directed directed through the center of the gear rather than offset will yield maximum strength.

hello. Been working on a small project of mine. May I just ask if you know how to salvage old phone screens and use it for this

2:35 are we just gonna let that voice crack slide?

Thanks for all the work you put into this. I must point out that you have made a mistake on sounds levels. Nearly everybody (99.999999%) doesn’t know that sound is measured with a logarithmic scale because of the great variation of levels which makes a change of 3db’s twice as loud. So 50dm and 53db is twice as loud.

From my experience with 3d printed gears it's always better to print with (for example: wall count 100 and Infill of 0% ) instead of (wall count 10 and infill of 100%). Depends on the gear size, the wall count must be increase to fill the whole gear even when the infill is 0%. The goal is to connect all walls (outer ,inner and hole walls) together.

겁나 멋지다~!

Beautiful

This is the best Cycloidal Drive i saw, so far.

Hi there! I enjoyed the video a lot - but the backlash testing part got very messed up. There was play everywhere - well, you pointed that out yourself and that’s good. But then… the printed parts could have been made with tighter tolerances. I actually don’t know how to proceed into creating a mechanically correct testing rig to compare them. If the mechanical wisdom affirm herringbone gears have less backlash and the 3D printed part is having more backlash, then it’s clear we did something wrong, right?

If you design a chamfer into the gear, you can avoid manual chamfering. I do that often when it’s critical. And the term is “elephant foot” not “elephant tooth”.

0:26 О господи? Штирлиц?)

Sorry ,your contrivance is not stable,The result is not true.Mill is so thin and not rigid.And there is single force holder aganist your appling force..You must change test your contrivance.

Obligatory elephan *foot* comment. Its foot, not tooth.

Elephant FOOT, not teeth..haha

You multiplied the power by 10.
