I decided to transfer what
I decided to transfer what was a blog post to a true robot page as I intend to push further my investigations.
I suspect that I didn’t use my DFRobot board properly: I didn’t used the right power connector, there is a separate one for servo power and there are 4 jumpers to disable to use pins 4 to 6 I think.
I hope to have time to test this this evening.

You are correct about power issues.
Just ask Bajdi.
He made some custom boards and made use of some UBECs(?) (Battery Elimination Circuits) to supply enough current to drive the servos.
I really appreciate the time you take to share the details good and bad with us.

Bajdi is on my list of good
Bajdi is on my list of good info on power management 
I just lack of time to properly learn everything I need, that’s the goal on top of having fun 
For the moment, it looks like 5AA will allow me some experiments. So I can start bugging Badji about UBEC (and learn what it means
)
If I don’t post a robot page, I put a bolg note. Every robotics experiment will be tracked here as I owe a lot to LMR.

I received all missing
I received all missing component and I’m ready to try different combination of regulator and batteries.
Even better, thanks to your work on uKubik, I worked again on my code.
The way you used the Serial.read didn’t worked in my case: don’t know why but it doesn’t really matter.
The most important is tat I worked on it again and have a way to address each servo from a serial connection.
I already had a look at PyPose when I was dreaming on Trossen Robotics crawlers. I think I have to keep each step small in order to still progress.
So here’s what I envision:
1) write simple python code to connect to serial and move one or two servos
2) write a basic GUI to control extended script wrote in 1)
3) add BT to avoid cable?
