Brilliant

First servo slider test run:

tomorrow I hope to add the (to big) FSR sensor and see what it will do
(I’m still waiting for the smaller FSR’s)

Thanks for your information.
I get lucky to live in the Netherlands, the shipping costs are free when I order one spool.
And with the 2.2kg spools it’s 30% less in price.

I’m sure I need to play with some settings (temps and max speed).
I hope to start this evening with some tests

I’ve used CollorFabb PLA for some time now and this prints…[Read more]

Haha If the time is there, it can be go fast

How about you, any progress with your “Right” hand ?

Almost done with my design. Just waiting for filament to arrive in the mail so I can print. My design will use many of Gael’s original servo bed and has a printable shaft. HAd to spend a fair amount of time hollowing out the arm and wrist parts but there is a straight run for all the tendons now.

Great Marten!
It’s added to the InMoov Derivative Collection:

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

Hi Gaël,

I’m happy with this update, it helps a lot to run all the fishing lines more freely !
If the small servo’s are still a life after a stress test…
There is more space left for other functions.
For the stress test I need to make a nice script or better just use a simple Ardiuno random sketch.
So I don’t need a laptop to be on all the…[Read more]

Thanks Rodolfo,
Here a video from this complete setup:

Tomorrow I will start to connect all the finger fishing-lines to the servo-pulley’s

It looks good so far

Yes
But, I still need to update some things.
Like the sevobed, so I can mount the Wrist servo on it.
And still some fine-tuning between the servo and the small gear.

I hope to finish this tomorrow.

Haha, my fingers are crossed

The Wrist servo is blocking the complete way for all fishing-lines.
With the servo placed on the servobed, it makes it full open.
So this saves a lot of friction

(printer is almost done with the last peace )

Hello Perry, this is what happen with my new setup.
The servo is placed on the finger servobed and with a axle connected to the Wrist gears.
I’ve a test setup ready now, so I will upload a video in a short time !

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.

My next step is to see, if the smaller servo’s are strong enough for the complete InMoov Hand !
I hope to find some spare-time tomorrow, during my work…

Tomorrow and the next two day’s I have some spare time during the day
First I need to finish my Wrist update, this will help a lot to run more freely !
Yesterday evening/night I’ve printed the first parts and one needs a small modification to fit better.
When this fits well, I can draw the servo part…

I will do my best, to show a moving…[Read more]

Thanks Perry,
You can download the pulley’s here:

Hi Richard,
I’m almost sure these smaller servo’s are strong enough for the Hand.
(don’t forget the special pulley which I’m using!)
The spring which I’m using now, is perfect to start.
If needed, I can use a stronger spring to get more torque.
I hope to show the results this weekend
My goal is minimum to hold a softball or a bottle of…[Read more]

Thanks Rodolfo,

Yesterday I’ve changed the servo-adapter to V2 !

http://www.thingiverse.com/download:2803246

These are easier to mount to the CS238MG servo.

I will install the new servo’s tomorrow in my Right hand…
So hopefully this weekend I can make a good video with all the results.
And I will make a Step by Step “How To”.

If you have…[Read more]

Hi Gaël,

For a 0 to 90 degree turn, I need to make them a bit bigger !
These are now designed for 0 to 180 degrees.
(please check your dropbox ! )

After some tests, I will upload them to Thingiverse.

Thanks Gaël

Hahaha, yes I’m still using the same Carbon Finger.
I didn’t print more Carbon Fingers yet…

Hi Gaël,

Thanks and yes, when all is running fine together…. I will share a “little” video
I think this will happen, when I get the new servo’s because of the fit to the pulley’s.
I hope to get them next Tuesday.

Hi Juerg,

I hope to save some weights with the new servo’s.
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.
I’m only not sure enough, if this is strong enough !

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).
And including my servo pulley’s, the finger “close position” gets a smaller arm length !
So this safes a lot of energy use from the servo, when the finger is in his “close position”
I’m almost sure this spring setup is enough to hold a…[Read more]

Thanks Gaël and yes it was “a lot of fun”

@Juerg, I’m guessing Amby sees it for the torso and stomach displacements.
The two armonics drive must be for the shoulders. Though when you know how much an armonic drive cost, you back off a little.
@Amby, yes, it is on that U-joint principle that I had designed the stomach rotations.

@ bob hello i use a toy moto like this

i find 2 in trash so i take motor for free
battery change easy when the battery is empty

@ gael hello gael is very fast this motor for robot but i can drive slowly

hello gael yes of course a can give everybody plans for built it this plateform very cheap but in first i builf in cardboard for prototype and when all is ok i give plans and informations
i design a connectors for wheels and motor
so i use a motorcycle for children find in trash a small bicycle children find in trash and i use a batterie for drill…[Read more]

Thanks Gael !

Haha, I can’t wait…
I’m printing the last day’s at Day and Night…
I hope the forearm is ready in about two day’s.

Next day’s I will check all the lengths which each finger needs to lift them completely with the new servo pulley.
So I can start re-designing the pulley for each finger.

Hi Gael and thanks for your comment and time

The elastic cord is a basic peace which you normally will use for clothes.
It’s now just to do the job of the spring.
I’ve ordered some springs and have to wait they will be here.

I hope the asymmetric effect is in a positive way
At the end of the finger position, the servo can give more…[Read more]

Thanks Gael,

And good to now about the limited thickness.
I will check this when all underarm parts are done.
There is a easy way to save some hight if needed, I can include some holes for the two screws.

Hi Gael,

Just checked the hight and it fits fine.

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 ?
Here I’m using a MG996R servo and it turns a full 180 degrees…[Read more]

Hi Gael,

Not yet, I first like to now if everything will fit well together.
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.

Here a direct link to download the the code:

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.
(OK I’m still playing with some settings like Nozzle Temp and PrintSpeed)

About the servo:
The thing what I hope to test, is that we can use smaller servo’s so we getting less weights in the Arms !
Each gram what we…[Read more]

I don’t now yet with the fingers.
The CarbonFil is great stuff and feels strong.
I’ve used this to make some prototype parts for my Camera Gimbal.
And it didn’t break
For now I’m still waiting for advice about which glue I can use for this CarbonFil.

I will come back to this question if I now more

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.

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.

Hi Gael,

Thanks for your offer about the spare hand
It’s no problem to print it myself, it’s a good test for my new UM2 configuration.

I think there is a easy way to place a magnet in the top from the Vingers.
This peace is printed in two parts, so I can drill a hole from 2mm in on of the parts.
For the Hall sensor I’m not sure about the…[Read more]

thank you gael i working to find a nice solution for my ankle and i do a video after for show everybody and in opensource

salut gael oui on m a fait cadeau de ta casquette je pensais ne pas l avoir et je l ai eu super content en plus elle est tip top comme j aime
