Here some pictures to show the difference between the servo weights… The MG996R was my first choice for the InMoov hand. The CS238MG servo weights including a mounted servo-adapter 30gr. less as the MG996R ! So if I will use these CS238MG servo’s for my InMoov hand, it will saves a 150gr. of weight 🙂 I think when I’ve finished the new…En afficher davantage
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…
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…En afficher davantage
Sounds good… looking forward to your results…
If you like to print my new Finger_Starter kit including the new pulley’s, here you can find all the files 🙂 http://www.thingiverse.com/thing:1794206
Have fun… 😉
I will use your idea in my Inmoov Rigth Hamd
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…En afficher davantage
Many Thanks Marten, I wait impatiently your Video, and your « How to ». It’s a very good job
Today I finally received my smaller servo’s 🙂 https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=51891 After printing a servo-adapter, to mount this smaller servo in a standard servo place… I made some tests with the new pulley and it looks all great ! The current use stay’s very low, even when I’m holding down the…En afficher davantage

Hello Jose and welcome. Thanks for these information. Do you have a picture of the head done with smatfill high resolution ABS with code decimals and centesimals? I would like to see the quality it gives once assembled.
Hello, to say to you that I am the president of an association of drones, robotics and engineering, and we work also with 3d printers having come to a great point of perfection. We work with prusas i3, flashforge creator, ultimaker, makerbot replicator, etc. It is the most important in all our printers to calibrate at least the filament in the…En afficher davantage

Hardware Is Here Build Update 2 going smooth
Lots of servos and materials ready, it smells like a fresh InMoov is on the go.

Hello,
I am trying to find servos for the bicep but all the suggested ones (HK15338, Hitec HS805BB, TS-80 Tower Hobbies,HS5805MG) are out of stock. Any alternatives that i can use ? I am trying to find them in Europe preferably….
thanks a lot George
HS 805 BB available here http://www.robotshop.com/ca/en/hs-805bb-giant-scale-servo-motor.html TS 80 available here http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXLN94&P=4
Both in North America though
Ebay might be your friend: http://www.ebay.fr/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR0.TRC0.H0.X805bb.TRS0&_nkw=805bb&_sacat=0
Thanks a lot for your reply. I also found the Turnigy™ TGY-1270HV Ball Bearing DS/MG Servo w/ Heat Sink 40kg / 0.18sec / 170g. Do you think that they will fit and work ?
thanks George

Lol part of the preparation was making sure, I was sufficiently motivated to continue to the end, then the construction of a little workshop in the garden for building InMoov and buying equipment etc.
I think you mean: InMoov gets his own house in the garden ? 🙂
Enjoy your InMoov build!
He does, thank you, and his own exclusive 3d printer. I will have to learn to be patient! 3d printing is slow!
Oh man this will be the first InMoov to have his own house!! Great!!
After month’s of preparation, the first print, 24th September 2016 what a great day!
Hello Michael! A finger in the Wanhao! That’s for sure it’s at least a month of preparation. What will you do next month? Just kidding, hey! Thanks for sharing your enthousiasm. 🙂

sorry if i did any mistake
its my first vedio on inmoov so please watch it full sir
Great video Akash, I can see that you did great progress learning how to use MyRobotLab! Isn’t it great to be able to voice control the finger? Of course it means you can voice control all kinds of devices with MRL through the Arduino. Check the various services, like camera, tracking, I ‘m sure you will find all kinds of projects to do!

Here two views from the pulley which I’m testing with the Finger Starter Kit V2 🙂
When the Finger moves to the Open position, the pulley is pulling with the small circular side. And when the Finger moves to the Closed position, the bigger oval side is used to pull the Finger… The servo makes a turn from 0 to 180, that’s way I can use a…En afficher davantage
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.
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.
Here a video from the new Finger Starter kit V2… The servo current use, stay’s very low during the test, sometimes it’s passing the 0.26A during a start. (I’m still waiting for the new servo’s, so a second video will come soon !)
Regards, Marten
Wouuii video great Martens.Did you use your carbon filament?
Thanks Gaël 🙂
Hahaha, yes I’m still using the same Carbon Finger. I didn’t print more Carbon Fingers yet…
Hey that looks like a good starting point. Right hand, check Finger, check RobCap, check…

Hi Gael, I am from India. Can you please tell me what filament have you used (ABS, PLA, etc) and total of how much filament have you used for making the inmoov.
Best regards, Subham.

@markus Love your InMoov base however looks to be rather expensive to buy or build one?
Hello Juerg, Markus had posted all his mecanum wheels design here: http://www.thingiverse.com/thing:1116924
akash dixit a publié une note il y a 9 ans et 8 mois
is anyone is there who is making INMOOV in india ?
There are not many in or around India. See here: InMoov World Map https://goo.gl/maps/G9jcZJjDciB2
I have sent 8 times Nervo boards to India. Five of those orders were dual Nervo Boards with components, so I suspect 5 other InMoov getting built in India.
Hello Gael & Akash.. I am virendrasinh from Gujarat, India. I am 4th(final) year undergraduate student of Engineering. I am also making INMOOV(awesome) robot(started before 3 months). I will upload post soon… Thank You Gael for everything making Opensource.

Finally the Arduino fits well in the updated FingerStarter_Kit. (see picture) The new pulley and adapter for the small servo also fits well.
I need to say….. I’ve found a other servo, which is a bit bigger and has 10gr more weight The good thing is, a standard pulley like Futaba will fit. And it has 2,1kg more torque as the small…En afficher davantage
Very cool Marten! Once the finger is assembled, a little video will be nice to see!
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.
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.
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 !
how did you print the carbon item? Layer size? Perimeters? Fill? what tensions are you using? did you try to reduce friction of the tensions?
