Nice video @ozzytrooper 🙂

And single headers you can break them easy by hand.
Double or more rows, you will need some tools to cut them.
For the 14-pin flat-cable connector, I’m using a small vice.

Hello Steve,

There is a difference between PMW which is used to control a dc motor speed (H-bridge), or a PWM used for servo’s.

The PWM for controlling the speed for a dc motor, or intensity for a LED, is at some pins hardware-based (internal circuit/timer, to sending a PWM with a fixt frequency in the background.)
These pins are the pins where…En afficher davantage

Hi Ashley,

Welcome to the InMoovers 🙂

MRL is (in my eye’s) much stronger/faster then Arduino IDE/Boards itself.
It’s running at a faster system then a single Aduino board, so there are much more options possible.
And the InMoov is a default Robot in MRL which is cool and more easy for beginners.
There are some Python script made by other…En afficher davantage

It\’s a nice option to use the default servo\’s 🙂

And are you happy with the mechanical results ?
For you it\’s better to see and feel the results instead of the default setup 🙂

CollorFabb PLA is good material anyway.
XT can handle a higher temp when it\’s printed, this part is a positive thing if InMoof stays for a long day in sunlight.
So maybe I will use XT for some outside parts and all others with PLA 🙂

Thanks for your information.

I think after this weekend I will upload all files, which are needed to upgrade the Wrist part and this includes the new ServoBed for the small servo\’s and the Wrist servo.
I can\’t see that these smaller servo\’s can hold it for a longer period 🙂
But so far it looks good and including the springs I think it\’s safe enough to use them!

Hi Perry,
Yes for sure I will include the springs which I\’m using with my Finger_Starter kit.
This makes programming a closed position more easy and they are to safe the servo mechanical way 🙂

Check my last post, to see the full functional Arm/Hand/Fingers:

The Wrist servo is blocking the complete way for all fishing-lines.

I\’m sure you will like the spring, if you hold or take a glass of wine !
I think the spring has enough pulling power and is more soft 🙂

Always cool to see other InMoovers growing up 🙂

And a MG995 must do the job 😉

Thanks Richard,
Mechanical way it looks good enough for me.
These pulley\’s will need the full 180 degrees from a servo !
Make sure your servo\’s supporting this 180 degree turn.

I didn\’t print more Carbon Fingers yet…

They have three times less weight then the servo\’s which I\’m using now.
And the servobed will be smaller.

About the printing parts.
I\’ve done one finger with Carbon fill and is very lite.

Hmm, it sounds there is something else happen with your servo connection.
If there is a shortcut between the Arduino shield and the small PCB, the flat-cable will start getting hot !
Please double check if there is no connection between servo outputs 10 and 11.

If possible could you send me some pictures from your boards?

Hi Gaël,

The spring main function is to safe the servo mechanical (there is no direct blocking anymore).
