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.
Most people will have this or something look like this. -

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…[Read more] -

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…[Read more]-
having arduinos only will have very limited capabilities of controlling the whole robot. think of optical object recognition, speech recognition and voice output or simply look at all the services MRL is providing

Great Marten! I want to see when the pulley is set in the servo bed how the servos are acting. As I said in our email exchange, I have burned so many MG996 and MG995, that I do not trust those servos anymore. I never, yet burned a HK15298.

They may save weight but they may not be strong enough for the inMoov hand… The hand is not the same as the finger starter. There is a lot more friction on the push/pull finger mechanisms.

There is no doubt that the servo of 2,5kg will work because even a small SG92R works. With the Finger Starter there isn’t much friction. But such servo will burn for sure if used in the hand.

Agree that individual pulley’s for your combination of servo and finger would be safest for builders. Just go 0 to 180 without having to worry about limits.
I am rather the software guy and think – once the mechanical part looks good – I can control movements with the mapping function of MRL.

Hi Marten
I think before changing the pullies we should agree what the mechanical requirements are for the fingers.
In my arms I use mg996R and they can turn about 110 deg to the left and to the right (total 220). So when Gael says he can move all fingers with the exception of the middle one with an unmodified HK15298 servo which allows only 45…[Read more]-
Hi Juerg,
Thanks for your input about this.
The good thing to use a 180 degrees pully, is that there is less change to break any mechanical parts.
A other good thing is, there is a higher resolution to place/hold the finger at his position.
Have you seen my Finger Starter video ?

Springs will the best/easiest way to solve the problem.
I will use this Pully, including a spring to let the finger go down again.
I haven’t springs at home to test, so here some different views from my drawings and a mounted pully at a servo:

If yes, I will place it on Thingiverse.I\’ve seen the two other designs, but all have the same thing by some servo mount places.

The best way to use this sort sensor, is to include a servo slow (step-based movement) which I have included in my code.

Hi Marten,

That carbon filament is great looking!
I did make a Arduino script when I was testing the carbone foam sensors on the finger starter. I’m wondering if I still can find it in all my data. It could maybe help you or others, as I recall it was a bit of a different approach.-
Found the script back in my data base:

const int sensorPin = A0;
int sensorReading;int pos = 0; // variable to store the servo position

Haha, yes the video is good for all the joint parts.
I was more focused how to glue all fingerparts together like part-1 with part-2 etc….
CarbonFil is PET based and PET is difficult to glue normally.
I hope the 30% of carbon-mix will make it easier to glue this together. -

Hey Gael,
The CarbonFil is more PET based !
And yes, it’s nice material to use but it needs some attentions for the first layer.

Hey nice Marten!!
I like that Carbon PLA. I remember the parts you showed me in Eindhoven, the quality was very good!
Pulley rotates 90 degrees because the HK15298B digital servo recommended for the hand rotates only 90 degrees.
That being said, you can use any servo you like with Finger Starter and of course model your own pulleys.-

Hey looks great. Many, many more parts to print however …

Hi
thanks for your comment. What is your print bed made of and what temp / preparations do you need to make the pieces stick to it?

I got the same trouble. Happily with abs it can be repaired quickly with acetone.
Some times after I found this tip, just heat to smooth the holes. It looks like Mats Önnerby tips with airgun to mount pla parts but with a solder iron.
Have a look on this video :
Hope it can help.-

Great prints Marten!
In the video posted by Sebastien, the idea is great! Specially if you drilled the holes a bit too wide.
But be sure that finger stays loose, in the video they are stiff, rigid, and that is not okay for the movement. The finger should move freely at each joint.-
Haha, yes the video is good for all the joint parts.
