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?

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!!

Very interesting Markus, I’m surprised how well the mini joysticks + remote are reliable to control the arms and hands.

Great Markus!! This is cool to be able to control the arms gestures so easily.
Once in position, can you still “capture the gestures” by voice to compile them later into one gesture?

Hi Robyn,
Congratulations for your record !!!
Say Hello to Markus for me 😉

Looks great Markus, where did you get the battery cover panel from?

Great job Markus!! I love your wheel platform, especially when i see Robyn driving!!

Thanks for sharing that video, Markus. Looks like it was a good time. Did Gael mention any time frame for the legs to be released ?

PS: removal of the slurry ABS on the glass after print is done, simply run under cold water tab and it will detach itself like magic. Dry the glass plate and you are ready to go again.

Hi Gael – great info thank you.what is the consistency of the ABS slurry you use. your prints are look great.

Hi Gael
I still think you should give HT-PLA a try and use a print plate that will not need any slurry or tape and allows to remove items by just picking them up from the cooled out print bed!

i am making inmoov right hand so can i get the Tensioner.stl file for it please i am not getting it anywhere can you please provide me the link of it

Great video Markus!
Always on the cutting edge!
I recently tested the webkitrecognition during an event and got a bit frustrated with the delay for to get the responses from the server. When the wireless connection is poor, InMoov has to “think” for very long seconds, it can be up to 20 seconds which feels like an eternity on the front of the…[Read more]

wouaaa it is hotttt lol
amazing

Uhh, Uhh, my printer manufacturer had changed his print bed product line to make it almost impossible to overheat it (you could fiddle with the control SW however).
I assume some workshops could run into serious problems having the printbed burning through.
Think about switching to PLA-HT (or HT-PLA) which is as good as ABS but prints on a 50…[Read more]

no idea, what is this good for?

Aaaah the French beret!

Ah finally switching also to a more recent version!

ProgramAB with the webkit recognition works SO much better now.

Last version 1114 still had trouble with loosing an Arduino and the jaw got fixed in version 1113 by Kevin.

Wooooiii we are close to a steady version, waiting for it since more than year, ahaha.

Finally robots will ask for vacation time????
Nice setup – how can I book it for myself?

Ehehe, once again Robyn is enjoying life for our own pleasure!
Always makes me laugh a lot!
Thanks for keeping up the cool videos.

Ahahaha!
Always love your videos! You could get a sound added like a hard curve driving.
Like iiiiiiiiiiiii
http://tubidydb.com/mp3/tire-screech-sound-effects.html

This is awesome! The 2 topmouth pieces have always been kind of a pain to work with, so that will help alot.

Ahhh, great, I had started to add flabs n stuff to keep them from falling apart.

What a great concept Markus!
I will be glad to see that in Paris for the Makerfaire!
Where did you get those relay boards? Do you have a link?

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

Super cool !!
Your choice of colors remind me of Leonardo’ super hero:
http://inmoov.fr/members/leonardo/album/
How is the Raspi doing for post processing video tracking on MyRobotLab?
I will post the Back Parts soon…

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 🙂

Thanks Gael, now I see how it all works. I like how you can detach the drive wheel to push it around manually. See my comments on Sebastiens’s post.

@Bob, to answer your previous questions on Sebastien’s post:
The base can carry InMoov easily. You can add at least 10kg and the base can still ride fine as long as the floor is flat.
When I use InMoov in the street, the wheels can overcome some holes if it rides full speed. If you look at my video, you can see a battery carrier between the two…[Read more]

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.

It is nice to see young people working on things like this.

Well Markus, this works very nice. I can see how effective this works, and the sensors seem to be working well.
I guess you could also use it to create gestures, if both arms were not coupled, using “capture gesture” voice command.

Yes i have both sensors working now thanks to Greg and they move separately.
and it is very easy to create gestures.
there are so many possibilities
for example interaction with people.
my experience is that many people want to touch and feel with their hands
and now Robyn will respond to that.

@Kevin, so I’m trying to figure how you proceed with the webGui, but I seem to just run into bugs.
When I open the webGui I get old windows of InMoov hand that I tried a few months ago. I can’t seem to release those windows.
I experimented under WindowsXP, could maybe that be the issue?

Nice work, Markus! I see lots of applications for these touch sensors. I have also experimented with them.

Nice works, Makus! I see lots of applications for these touch sensors, giving a robot the sense to “feel” is huge.

Amazing! Looks great, easy to imagine this in a variety of applications…

Super Great Markus!!
Actually we could make just a tactile bracelet for easy driving control!
That would be easier to make, because I remember you saying in a video, that it was a bit difficult to make the sensitive forarms sensors. And the videos does show the difficulties of the task.
I don’t remenber, did you use i2C to save analog entries on…[Read more]

Oh and I see that Robyn is getting ready for Christmas!

Thank you very much, was waiting for him, it was what I needed.

thank you gael

Thanks very much Gael!

i have made some changes after this video because i needed more power to the motors but the sketch is sill basically the same

Markus, this is so great, I really love those mecanum wheels!
Are you using the Joystick service of MRL? Where did you get these cool little joystick? Can they work as remote control without cable?

Very cool, Markus! How do you have the controls arranged? For instance, how do you distinguish between “turn right” and “go sideways to the right”?

Woaaaahhh awesome!! Now its time to make space in the house to let InMoov ride around!!!
Just incredible to think you are able to build this wheel system with a 3D printer, ahaha! I have added your Thingiverse files to the InMoov collection. This is SO inspiring!

That looks great, Markus. I was wondering – how do you have your controls arranged to cause the 10 possible movments?

Awesome Gael and thanks for the files and the tutorial.

Fantastic,
Very Great Job, thank you very much Markus for sharing this,
Robyn is going to be able to do many tasks at home 🙂

Awesome Markus!
Thanks for sharing your work with the community!

Hi Markus,

Cool to see these results (I’ve seen your first video about this project at MRL)
It’s running fast to 🙂

I’m sure, Robyn will enjoy this new tool to.
Thanks for sharing this driving system for InMoov.

Aaah Markus, I’m glad you finaly post your video on InMoov site for other builders to see what you are working on!
Super progress!

OOOhhhh Yes,

This is very good news Gael 🙂
I will soon start printing the head, so your update is just on time 😉

This week I will receive my new _XT filament from ColorFabb.
I hope it’s a good filament to use for most InMoov parts, even for the shoulder mechanical parts.

Other question about the camera, are you still happy with your…[Read more]

Hi Mats,

Is this a option to use:
https://copy.com/1K7hNQFiuvHMBHUh
(sorry, there is no option to upload a picture directly in a commend)
As you can see at the drawing, there is a normal sized part (left side) and a smaller sized part (right side).
For the smaller side (with a oval form) you have to play to get the correct length you need.
If…[Read more]

Hi Marten. I just cut of a few mm’s of the hand cover support. It’s only there to support the structure during print. I don’t want to replace the dual track pulleys since they work very well. Have a look here for a demo https://www.youtube.com/watch?v=b5S-8hjsMr8

Maybe reducing the filet height for the tendon, this way the pulley would be less high and wouldn’t cause a problem with the covers of the for arm.

Awesome solution for tensors Mats!
Thanks a lot for it and for sharing it over thingverse!

Saved me $$ on springs!

😀

Ehi Mat, thanks for sharing!
I will print one to test on a finger starter kit to see the effects.

Woooii cool

Pictures were uploaded in a different order than I expected. So the last picture shows the open finger with lines stretched and the two other when it’s closed and the lines are not stretched anymore.

Very good idea the “double pulley”. You get the same results for the pinky and middle finger ?

Very good idea!

This looks interesting – How would you describe the improvment to the hand’s movement?

The reason I am asking is if you think the springs that were introduced to keep the strings tight would still be needed ?

Cool and sure, MRL deserved it to get placed at the shoulders from InMoov.

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!

@ Bob Houston,

This looks awesome dude, great work and a cool upgrade to the InMoov !

I can’t wait to see some more video’s with the Eye tracking options 🙂

bonjour tout le monde!
est ce que bob Houston pourrait faire partager a la communauté inmoov les plans et les fichiers stl de son châssis et la colonne sur roue qu’on voit sur la vidéo youtube?
merci d’avance

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]

That looks like a very good design I really like the eye movement

Hey cool ! Thanks for posting the video!! I love to see stuff like that. Yes the speed of the jaw needs to be increased. Bob Houston has made a remix for the eyes, I wonder if it fits in one normal InMoov head.

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

Sorry for posting so fast Just got excited when I saw the pictures from your trip you posted, when do you think you will release them?

That is a really nice back. Looks good and will protect all the electronics and hide some of the servos.

Great modification! I’m printing it now. Thanks for sharing the STL’s.

Great!

Awesome work!
I like the way you re-arranged the space to be able to add the Raspberry and the Arduino. Does the jaw still have a servo attached to the mechanism?
I sure would like to see a video of the eyes in action!!
Thanks for sharing your modifications on Thingiverse, I appreciate you respected the licence. I have added all three links to the…[Read more]

Nice upgrade Mats 🙂
I’m sure it will be a EyeCatcher !

I hope to print the head after my Finger Sensor project… and will use your EyeCatchers 😉

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]
