DIY Linear Servo Actuator 3D Printed with full Positional Control and long travel 

Thanks a lot man, please share the video link too

Glad you liked it. Please like, share and subscribe

I've same question

@@mutthunaveen probably they used different servo, where the pin is not a shaft of a gear

@@SergioGugliandolo yeah Sergio... I read all comments they are doing the same...

Glad you liked it! Regarding the gear designs, the Fusion 360 has inbuilt gear designing scripts/plugins which make it more easier to design gears for all purposes, you can find some videos online, or if it feels to intimidating, let me know, I might make a tutorial later on for gear designing using this project as an example. Please Subscribe and share, thank you.

You should increase the radius of the pinions.

Thanks bro!

@@beardoguy I quickly gave print and simultaneously removed a sg90... Found that the pot connections need to be taken out and sacrifice another servo potentiometer for 2nd gear... Hmmm.... Design could have improved with rm065...anyhow.. good design though... 😎😎

@@mutthunaveen I'll look into the rm065, thanks.

@@beardoguy nice... We can cut the wires of inside pot.. and put any resistance value pot outside (resistance value doesn't matter because all the IC reads is the voltage from VCC to GND) so any pot should work...

😀

thanks a ton✌🏻

Hi, I am from India, don't know much about printing services available in your area. I used my own 3D Printer at home.

Yes it can be increased to 90mm by increasing the gear teeth on the rack driving gear

Yes, it can be precisely controlled as needed, that's the main advantage of this design.

Hi, the stls asre posted on thingiverse, link is in the video description www.thingiverse.com/thing:4557945/files

Yes it would be possible with a DC motor too but a microcontroller will have to control the DC motor using a motor driver and control its position based on the feedback from the potentiometer

thanks a lot bro!

Make more videos

I use the in-built gear script in fusion 360 software

Sir, it's not for sale right now but you can 3D print it, I will put a link in a few days

@@beardoguy sir u want to purchase it . I searched much bt cud not get link for online purchasing.

Just use the included servo test code in the Arduino ide.

Yes, you have to connect it to the potentiometer

thanks, I'll be posting it within a few days

I have updated the link to the 3D files, please subscribe to my channel for more 3D stuff

No, I used the one that was inside this one

And I think different servos have different internal design (especially these chines ones), I'll have look and let you know

I'm running into the same issue​. @The Beardo Guy (amazing hack / thanks for sharing the 3d models btw!) could you please show how you reassembled the cogs inside after you've taken out the potentiometer? At 12:43 it's clear there are 2 rods, one of which seems to be the potentiometer's, so the cogs that relied on it need some replacement at least on my model. Also the axle of your potentiometer sticking out of its cog (as briefly glimpsed at 1:28) seems wider than that of my servo. @AZHAGU05 it makes for an expensive potentiometer to take it from another servo, but that's my current workaround, I'm glad you suggested that! I've gutted most of the potentiometer's insides / only preserved its plastic base and metallic rod (the lack of wiper creates an extra 1mm+ gap, which I might try and plug with a washer below the plastic base, unless I 3d print some alternative, thicker plastic base). This allows the "former potentiometer" to rotate 360. Alternatively, for a cheaper result, one could use another potentiometer of the same resistance and modify the 3d-printed cog accordingly

I was a bit busy these days, I'll upload it soon

@@beardoguy Thank you so much, i will share it so new people will know about your content. Its great.

Glad you liked it, I'll be making more 3D printing videos from next month, keep sharing and subscribe to the channel

I have updated the link to the 3D files

@@beardoguy Thanks!

That will work just fine, the only reason that I got the internal one out is I couldn't find any good quality potentiometer in my local stores. Thanks.
