Flexible finger joints for InMoov
Bob Houston posted a new activity comment 5 months ago
Try decreasing the size of the screw by 2 or 3%. That has worked for me in the past.
I had to do the same as my printer was not perfectly calibrated. I scaled in the X and Y directions but not the Z as this would change the pitch.
I had this problem with the jaw screw. After reading Perry’s comment i looked into how to scale stl files. Turns out it super easy using NetFab Studio, so i’m going to give it a try on the neck screw.

See my comments in the Forum
Do you print with PLA or ABS ?
printed material: ABS
Bearing: R-1560 Zz / 15 mm x 10 mm x 6 mm
Servo: MG 995R
This is very impressive!! thinking of changing this on my InMoov.
Where does the R-1560 bearing go? Looking at your build and can’t see it, apart from the ball bearings? What am I missing?
Sorry I see them now!!
Wow, looks great and it seems to handle the weight of the head really well. I see the STL\’s on thingiverse – thanks. What size servos and bearings did you use?

I made something similar that was the wrist for the Parloma hand. https://www.youtube.com/watch?v=hoNCKCTcoOE
Yours looks much stronger, you have a video of it in motion? I think it has some potential.
Yes, it’s a remix Parloma Wrist. Video can be seen at: https://www.youtube.com/watch?v=_7ZdPfpy9CA&feature=youtu.be

Is the article accurate?
Ok I shouldn’t ask but are other inMoovs invited to the bachelor party?… I have just the entertainment… https://www.youtube.com/watch?v=xulnNDLlXf4
This is an interesting article.
OK, I\’ll bite. What is it?
? a brand new dual extrusion head with coolers for the object and the extruders? Cooling the upper part of the extruder can prevent clogging – good. Enjoy the pic – once you start printing it won’t look as good as now!
for ooze free multiple extrusion in a single object have a look at this
It’s a dual extruder upgrade for the Vertex K8400 3D printer from Velleman. I can easily identify it, since I have the same printer for almost 2 years now. It works very well for PLA printing. It makes it possible to print different colors, but more importand, different materials. I tried it about a year ago, but at that time I have print quality…[Read more]

Mindless, I have downloaded your 3D InMoov Man – nice work. Should I be able to move parts around so I can see the internal parts? The drawing loads as a \”Read only\” file in SketchUp. Or is the drawing just that, a drawing of the assembled parts?
Left-click a part (to highlight it in blue), then right-click and choose Hide.
It a complete 3d model,,, so you hide parts to see inside him- or you make changes to parts then export that part as STL (Need Plugin) and print them out-,,, if your new to 3d modelling it will take a bit of time how to work stuff out,,,- but SketchUp is one of the easiest of the 3d modelling platform-
The “load as read only” message means its dou…[Read more]
Sorry about that,,,,,now where was I,,,
But you cannot work on the same file in two different widows —,, think of it as a “Master and Slave” set up,, the first time you open Inmoov man is the Master and if you open it again without closing that Inmoov the others will be loaded as slaves (read only),,,, and you cannot modify the slave ver…[Read more]
I’ve just downloaded your 3D model… WAHOU !!!
Excellent job, it’s very fun to see the bot in 3D.
Very convenient for mounting and color test.
Thanks a lot for sharing

Try these ones, they are the same as the HS-805\’s but only $27 USD.
Cool,,, I’ll get a couple of them for testing,,, at that price i can fry/destroy them without worrying about it,,,, going to use these in the end (see link) ,, providing i don’t find a problem with them- there a Australian clone of the Savox ,,,, but beefed up,,, not down,,,, bit pricey ,,, but the torque is good, and got the 7.2v option too…[Read more]

Thanks a lot.
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
Here you go. Still a bit of a WIP but curious to see how it fits for others.
Agreed, nice work….
Indeed, very cool design!
Thanks for sharing

Thanks juerg, I\’ll check into it more as well.
mmm good idea, i add too some capacitors to prevent jitter ( i test it tonigh ) : http://letsmakerobots.com/node/12679
let me know about your caps result. I had an issue with a digital servo impacting another analog one. After connecting the dig servo to another power distribution point the problem resolved itself but having a cap for the signal lines looks to me like a more robust solution
I think we have the same problem, I have mixed dig cys and analog 805bb. I tell you the results soon
Thats a good idea! Can you share details on how to install them?
Sorry, yes, just route the connection from either plus or minus pole from the power supply to the servo through the fuse. The fuse is supposed to heat up with current flowing through it and increases resistance thereby lowering the voltage for the servo and make it stall. The fuse regenerates when cooling off.
The fuse works in a slow mode so…[Read more]
Thanks juerg, I’ll check into it more as well.
Update: Actually had a problem with left shoulder rotation servo (continuing small repositiong with growl) and after a while it stopped to move (fuse and servo rather hot) so the fuse did it’s job.
Have added now the 104 (100nF) caps for all shoulder servos (between signal and ground) and as it did not completely stop the growl a lot of has gone…[Read more]

Did you do the same thing for the covers you have on the back of the Biceps?
No I found those on thingiverse
Good idea, I need to do the same thing for where the computer goes, as I\’m not putting a computer on my InMoov at this time. Maybe some one out there can make a filler plate for this space.
Looks great Markus, where did you get the battery cover panel from?
I printed a 2 mm thick and used a hot airgun to shape it.

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 ?
Bob Houston posted a new activity comment 1 year, 6 months ago
Look forward to seeing it in action. I know it is difficult to implement more servos when running on my robot lab, that\’s one of the reasons I switched to a different operating system to run my InMoov with.
I have this idea when i had soon need to use not implemented servo
leftPort = “/dev/ttyACM0″
rightPort = “/dev/ttyACM1″
7 +i01 = Runtime.createAndStart(“i01″, “InMoov”)
8 +right = Runtime.start(“i01.right”, “Arduino”)
#not implemented servo pin init
you can use
servo = Runtime.createAndStart(“servo”, “Servo”)
Hi it’s better thank you for the tip !
Looks great, nice prints! Can you post a video of it working?
at this time it is only possible to show every single axis working
because my robotlab is not working so far.
I try to make some videos this week end

The parts for this modification are on Thingiverse.
Thanks for your comments, Gael. Over here we call that type of joint a U-Joint. I considered that type of joint for this modification but the ball joint is much simpler. I left the pots in the servos and used my modified pistons that I made earlier for the Top Stomach. The reason I am experimenting with this is, that for walking I think the robot…[Read more]
Bob Houston posted an update 1 year, 7 months ago
The ball joint
I resigned the Top Stomach so now it can lean Forward and Backwards. The design is a ball joint with 3 servos. It still needs some work but the concept is good.
Mmmh I had written a comment a few hours ago, but I guess it just disappeared.
Awesome work Bob!!!!!!
This is really adding a cool feature!!
When I was designing the stomach parts I wanted set in a 3d printed “rotule de cardan” (I don’t know how it’s called in English http://motopieces.fr/wp-content/uploads/2014/03/rotule-de-cardan-624×468.jpg) to…[Read more]
very good idea use this articulation bob
i think to use the same idea for ankle was the best
Thanks Bob for the name “U-joint”, I couldn’t grab it on internet.
You are totally correct concerning good stomach movements for to be able to have human gait ressemblance.

Hey nice work, looks great!!!! What are your plans for your \”Desktop InMoov\” ?
Hi bob – thanks. you can actually make Inmoov look very good with a bit more thought and patience on the finishing and build. its a great cosmetically pleasing robot.basically the idea behind it was to have a more portable one. so i can transport it and play around with the programming – plug in the power and sit it on coffee table or any room i…[Read more]
Very very good Nanomole!
So your desktop InMoov will never have arms?
hi Gael..never say never…..i have another complete InMoov, just wanted a more portable fellow as well.
he will probably end up with arms i think

Hi Jack, I am the Bob from Canada, we talked about a year ago( at least) email me anytime at firstname.lastname@example.org
Nice to see you are back at it. I hope all is well. I\’ve seen your progress on EZ Robots forum. Don\’t be afraid to post questions here or there if you have any. I am wondering what your plans are for the 2 cameras you have in your InMoov.
Thanks for the thoughts. Using 2 cameras in head but only one active now. Try to move platform top mobile self contained. I tried answering you via email last week but I guess I need to use forum to answer now. Are you the Bob in South NJ? Your project is fantastic! Keep in touch.!
Nice idea with the rechargeable batteries. What kind of motors are you using?
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.
Sebastien and Gael, Thanks for sharing the details on your bases. They are very simple and efficient. How much weight can the base carry/move around. Gael, yes, EZ Robot can do the voice controls as well. I can run my drive motors with Voice command, or manually on the computer or mobile app. I’m looking at building a lighter base like this but…[Read more]
@Bob, I replied to your questions on the thread in which I posted the video with the base.
WOW! That\’s a nice looking build.
Nice work! It is amazing what you do with cardboard ! Can you share some information about the motors you used?
I like your drive system. Can you share some details about the components you used to build it – motors, servos?
Thank you Bob, this InMoov plateform is widely inspired from the one Gael made. My components are coming from old broken stuff to make it low cost as it is a temporary solution waiting for legs :-).
The arduino uno that manage the inmoov neopixel ring is now also used to read commands coming from a wireless PS2 Gamepad ( thanks to Bill Porter…[Read more]

It is nice to see young people working on things like this.
Yes, I hacked a flexihand and put the servos for the fingers in the palm of the hand and added a servo for the additional wrist movement. I have also just finished adding flexible joints to the original InMoov hand and it works pretty good and can hold objects fairly well. I posted a couple of videos on Youtube about the flexihand.
Bob Houston posted an update 1 year, 10 months ago
A demo of the stomach rotation
Very cool movements .
As you have done to make the system of wrist motion up and down ?
Finaly you can post videos again!
I see you replaced one hand with the Flexi hand?
Nice video, Bob!
I see the wrist also has a movement linkage. You might want to share your work with Juerg, as he is also working on something similar.
RIght, you take a new route with servos inside the hand – very nice!
My bending wrist uses another servo in the forearm and a few modifications on the existing wrist and hand parts – and it integrates a position sensor to allow the hand to stay horizontal. I am waiting for some cabling stuff as I want to have the forearm pluggable to the elbow.…[Read more]
Looks great! The flexihand seems better controlled – is that due to a design improvement in the parts or just better tuning during installation?
PS I think we should chip in to buy you some switchplate covers so you can program your bot to install them
