How to fix a sharking servo motor? - Robot Car Blog Ep.2

Lets explore what can go wrong with small servos and how to fix issues! While mounting the PAN-Tilt Hat on the Robot Car Project, I noticed the servos shaking during pauses in movement.
Lets dive in.
This is the second entry into the Robot Car Blog, a test bench for an up and coming AI project that I'll be sharing here as well!
For examples of how to use this method of servo control, here is the pi car project's github:

*(I post relevant python scripts for the blog here)*

Awesome video! Thanks so much for this. Finally found the solution to this problem after a couple frustrating hours looking into things like using a decoupling capacitor to stabilize power, using a ferrite ring core to reduce noise, etc. Turns out that for my use case all I needed was your move and kill method!

[@Ian-Builder_of_Things]

My pleasure. I'm glad some of my on the fly problem solving could help with your project too!

[@Boo2New]

Well done builder of things!!! I enjoyed the video.

[@Ian-Builder_of_Things]

Thanks! This one is the best of the bunch so far. Need to replicate its style!

[@OZtwo]

wow, dude!!!OMG! and I was about to go out and try a Digital servo! THANK YOU! dang!

[@Max_Mustermann]

Thanks, this was very helpful. I had an issue with a servo buzzing while idle and ended up mitigating it by simply calling servo.detach() while not in use. Simple idea, yet for some reason I didn't think of it.

Excellent. My pan tilt build works well all day with an ESP-CAM. The Arduino is boss when controlling servos. A few years ago I took up SBC's and MCU's, I stayed with MCU's because of functionality, community and price. I never looked back. Minicomputers don't make good toys, MCU's do.

U solved my problem!! thank you so much sear.

[@Ian-Builder_of_Things]

Glad you found it helpful!

[@anekdoche7055]

thank you soo much, please keep making videos

[@Ian-Builder_of_Things]

my pleasure! there are 2 more in the works.

Bro i had a 1:16 rc car, after i used a month the servo was shaking. I hade no idea can you help me please😢

[@DIYRobotGirl]

On the car with the camera arm. Did you use a state machine and arrays for that. Did you run all the motors and servo in the same program? I would like to see more on that code. Did the power have and issue with running that at once? I would think that those motors and that small servos have a low probably a 1.5 amps requirement. I just realized that the mg996 require like 2.5 amps and my wall adapter I have powering it is only 1.5 amps. I feel cheesy once I realized this. I have been trying to figure out why I was not getting the power or the torque I needed. Still to do more research. But yea we need to start acknowledging the amp requirements and the state machine and the Millis and the arrays. Especially when we want to run different motors and servos or anything else at different times and different directions. Everybody just goes to the delay in the same direction and same time. It's not helping. But yea like to see the code on the car with the camera arm.

[@Ian-Builder_of_Things]

I can do a deep dive into the RC code for the car. The camera and drive code are the same script though it has multiple threads. The scripts are available in the GitHub link in the description.

[@Rami7605]

nice KISS concept.
In actual companies they use the KICU = keep it complicated and unusable

[@Ian-Builder_of_Things]

Indeed they do. I have had the pleasure to do work for some very large corporations though the best of them do use the version I give for southwest airlines. A complicated or "overkill" solution can become simple if it eliminates extra steps when you scale. Small companies have a way easier time dealing with unique solutions (that are cheap and bespoke) than big ones 🤣

[@Mr.ValueMoney]

Thx awesome video subbbed.

[@nellynfedejuan1212]

That was great! May I use Arduino Uno for this project for my device permanently instead of Rasp Berry Pi?

[@Ian-Builder_of_Things]

You definately can use an Uno for servo or motor control. If you want to do more complicated computer vision ( like the further steps in this car project) you be better served by a Pi or any of the Pi knock offs (Banana etc)

How i can contact

[@Ian-Builder_of_Things]

I added the email for the channel to the 'about' page if needed. The comment section also works - I am happy to discuss servos and other tech problems here.
