voila une idée originale …

Very nice, what servos did you use for your mini

That looks very nice.
Make want to think about getting a resin printer 🙂
All jokes aside, the fingers would look good with resin as well.

where to find the stl files

I’ll check it out once I build the original finger. Thank you for your hard work!

Nice, when will we hear some tunes?

Yes!
Now we are talking about maybe InMoov walking for 2018.
First InMoov step was done in 2017, but with legs that couldn’t really support the body parts.

That is one of the better parts to print all in one.

Cool, when InMoov does Shakespear!
Lots of phrases to add in the script.

It’s very interesting to see how the legs were mapped based on my 3D scan of full InMoov. Great work with the leg mecanism!
Someday InMoov will walk!

Looks great! You may want to put the bolted joints of the socket, front and back or else the side servos may hit them.

Nice and smooth.

Cool,,, which software ya using for the model-?,, its looking good–,,

Super, I love to see these progress!

Hey, rock it!!

Ha..Ha – He looks Confused–,,
The Prints look fantastic and that Bottom Photo is awesome–,,

Queensland – Australia,,, – I grew up in a really errr Redneck place- small country town guns and flannelette shirts everywhere—but I travelled the east coast of Australia working my way up and down for years– still got family in my home town and head to farm quite often but spend most of my time on the Gold Coast in Queensland – ( the chicks…[Read more]

Cool,,, any problems with the build process for the legs,,?

Great prints and build Perry!

Looking awesome Perry,,,, keep the Pictures rolling in–

I’m looking forward to seeing it walk unaided… 🙂

I don’t understand how the bolts hold in place. The one of the wrist has a clip, but the two in the palm do not. Can you advise?

Where do we get the nuclear power source? That will solve the battery issues 😉

Thank you Perry, down loaded them now and will fire up the 3D printer in the morning. Like the look of your robots back as one piece, did you print that as one piece or did you join multiple pieces?, looks very good.

I do like your work, Very nice.
Are you going to upload this to Thingverse?

Here you go Ray
https://www.thingiverse.com/thing:1798673

thats amazing

This looks amazing! What did you use / how did you smooth the parts and make the head one piece? 🙂

Looks great!
Keep it up

Looks awesome.

Great Perry!

Your second test seems quieter, or that a deception? Did you make changes to reduce the noise?

Hey Erick! Looking good 🙂 Have you designed these legs for Inmoov to stand/walk/balance or sit?

Nice to see. Are you planning to use 32 servos in the head, or is the plan to move one of the PCA9685’s to the body. I use one in the body and one in each arm. That makes the cable routing much easier and opens up for adding other i2c devices, like IMU, AD converters and other funn stuff. I have a few new i2c devices on my desk, waiting for me to…[Read more]

Hi Mats
The 32 servo connections over I2C will cover all the connections for eyes, neck, fingers with some to spare

I’m running with 20Kg PDI 6221-MG servos for the heavy duty lifting (biceps, shoulders, hip rotation).

Those particular servos don’t seem to play nice with the PCA9685.

It looks like it may be related to the guidance here on…[Read more]

great

great

Hi Rolf, I am very impressed with the fun move hand. It looks excellent. I’m going to build one as well. I have ordered flexible pla for the joints. Am I correct in assuming you only run five strings to the servos to close the fingers and you don’t need the other five strings to open them as well?
Can you tell us more of what you have done with…[Read more]

Nice, i needed that!

BTW, the setup will be the same like this:

– Alan Timm (@gestalt73) September 16, 2016

Very nice system,,,,, the design reminds me of that Japanese robot they finally got walking around,,,, Mr Gael has the legs designed but not released and he’s kept that organic look to them which very hard to copy- but getting the walking operation with the toque vs speed to work without him falling over is going to be a hell of a c…[Read more]

Hi Perry,

he looks sad, he needs a girlfriend. 🙂

Looks awesome Perry !
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 🙂

Great Perry, I see that there is many inventors around!

yep… Colorfabb is great stuff, iv tried every brand/type out there ,, i do a lot of printing,,, In Australia i use “Blueprinted” filaments which is pretty good quality for a cheap filament Colorfabb is hard to get here and its bloody expensive..
I only use PLA you would surprised how tough the stuff when printed correctly – you wont have any…[Read more]

Hi Perry,

It’s nice to see your idea about this.
I think I will see your complete setup tomorrow, I hope it works well and I can’t wait to see a video !

Keep up the good work 😉

Cool design Perry,
this is nice to give room for the tendons to run straight out from the wrist to the Servobed.

Nice. I am printing up my version now. See my post above.

This is certainly getting along well !!
Following your progress from close by, Marten!

Thanx Marteen you are very fast, Great

Great, infill 90% surely will give it enough strength

Really Fantastic, I’m “hands on it” , and ready to upgrade my inmoov’s right hand

That is awesome. No tensioning spring is the best feature! I guess you could add a tension spring like you had in your single finger tutorial.
I think this is pretty innovative which begs the question what does the rest of your bot look like?

Very nice Marten!
It’s very interesting to see how you managed the wrist servo, I guess we could add a second servo for wrist abduction. That would be a great extra feature. (Hand Mini breakout Nervo Boards and Nervo boards would need to be transformed and all scripts and gestures as well though…)
Will you test it running continuously full 10…[Read more]

Very nice work. I’m waiting to see the fingers and wrist working together. Fantastic

Nice, now it works

I wish that works, it’s a great Idea

Hello Marten. I came to that exact same conclusion last night while assembling my tendons. They have been very finicky and I am not confident the spring system will hold up. The wrist rotation really plays with the tensions and geometries. I was thinking of a system where the lines ran through the centerline of the wrist. The servo can be moved…[Read more]

Awesome Marten… going to try these servo pulleys with my new inMoov I am currently building… good work man…

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.
Initially when I created the pulley and the servo bed it was for to solve a restriction rotation of 90…[Read more]

Looks great. Exciting. what pulley designs are you using?

Nice job! Are you going to share the design? I would sure use it as I don’t have an on board computer either. Thanks

Great work and very nice adaptation. Which software do you use for to do that?
It doesn’t look like Blender. It’s interesting to know because other builders might be interested to see how you re-worked your parts with only the STL at start.

Thanks for the explaination Perry.
When exporting from Blender to STL format I use a plugin within Blender to check if parts are clean without inverted facets. This plugin did not exist when I started InMoov project, therefore some of my first parts could not come out clean
🙂
One of the reasons I do not create parts with too many round edges,…[Read more]

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. The servos need to work much harder than the simple finger kit… However, let us know if they work because less weigh is always welcome…

I will use your idea in my Inmoov Rigth Hamd

I want to test these pulleys for sure! I’m guessing it will be also okay for our servos HK 15298 which have a restriction from 0 to 90 degrees.

Wouuii video great Martens.Did you use your carbon filament?

Very cool Marten! Once the finger is assembled, a little video will be nice to see!

when trying to reduce the forarms weight – did you experiment with getting less weight from the printed parts too? Just had a chance to look at a fiber enforced part at an exhibition. It had a thin layer of fiber on top and bottom of the part (needs 2 extruders) but showed impressing strenght.

Hey Marten, that seems like a great modification. I have a question if you have a moment, since you designed the nerv boards. I have one servo (Rt arm omoplate), which when connected to the nervo board, gets hot and eventually burns when connected to the nervo board. The servo works just fine on a tester etc. I have seen in the tutorial, the…[Read more]

Hello Marten,
Very nice module for a Finger Starter!!!
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. The friction is far greater in many ways in the hand, that is the reason even a MG996 of 12kg Torque…[Read more]

Hey Marten!
Great pictures, I hope the mini makerfaire was a lot of fun!!

http://www.thingiverse.com/thing:1656088

no idea, what is this good for?

Very good progress Amby with your robot! Is the wheel platform large enough to keep the robot in balance when you drive it around?

hello gael thank you yes the wheels plateform is enough for balance
all is ok with my prototype cardboard so now i start to build in wood

Nice idea with the rechargeable batteries. What kind of motors are you using?

Very nice Amby!
It seems to have good speed with those electric car motors.
I really like your battery idea,! If I wouldn’t fly the globe with my InMoov robot, I would go for your solution!
Unfortunately we may not carry batteries like that in planes. The very common 6VAh batteries can be bought almost in every country, so when I arrive in a…[Read more]

Fantastic Amby, Whaoo two motors and two batteries !, you are ready for the InMoov Racing 🙂

Nice work! It is amazing what you do with cardboard ! Can you share some information about the motors you used?

Amby the King of Cardboard!
As I commented on your post on MyRobotLab, you could make Thingy on Thingiverse with the DXF and all informations of the motors, wheels and sources. Some builders could reproduce it in PVC or plexiglas.

Woooii cool

Awesome!
I have added it in collection of derivatives.

Woouuiii !
Nice prints! Well now the forarm and you just about ready to have a Right hand!

Nice!
So the white is the elastic cord and it runs all the way to the end of the finger, if I juge the white spot at finger tip.
What kind of elastic cord? Don’t you think it will stretch more and more over time?
I also can see the asymetric effect on the black braided line.

Interesting design! I like the idea to set the servo horn within the pulley. They might be a bit too thick to fit under arm covers though… Let us know.

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 Marten,
Nice work!
Did you post it on Thingiverse?
There is other derivatives there:
http://www.thingiverse.com/thing:1036300
http://www.thingiverse.com/thing:618449

Here the Arduino code, which has a servo slow function included:

#include

Servo myservo; // create servo object to control a servo

int potpin = 0; // analog pin used to connect the potentiometer
int val; // variable to read the value from the analog pin
int Pos;

void setup()
{
myservo.attach(9); // attaches the servo on pin 9…[Read more]

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 …
I give a filing to the finger parts where they move against each other because the printing in layers creates imperfect vertical surfaces.
I do not want your pieces get broken but does it feel like the you might brake the parts when assembling them? I broke several with PLA and ABS when…[Read more]

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.

Woouiii you are going to make wonders with that printer!
You should have told me when we were in Eindhoven that you wanted to build the hand to make some tests with the hall sensor, I could have brought you one that I keep for my robot in case it breaks.
Yeah, print first the finger starter it will be easier. Let me know for the finger tip design…[Read more]

Very nice!
I see that you are becoming a 3d printer master after being the king of cartboard.
I’m guessing what we see is for the knee rotation, correct?
Did you finally use the motors of the drills you bought or is it with a servo.

yes you are true gael it is for knee
yes i am always the king of cardboard lol i do all my tests with cardboard and when it is good i do on abs
i use a drill motor for castorama 11 euros motor batterie charger ans very strong

Ehi nice project Amby! some videos in action!! And specification details!
Controlled by MyRobotLab?
Other builders will love that.

Hey cool, you got a InMoov cap!!
