I would like to add a bit more control of the hand to keep it more horizontally (things tend to fall off Marvin’s hands). Any success stories or frustration reports about that?
Hello, I have found a pretty good solution last year. I didn’t post about it because I wanted to test it before. The hand was set up at an exhibit running the whole day for nearly two months, and the result was concluant. I will upload the STL files when I get a moment. http://inmoov.fr/wp-content/uploads/2015/06/DSC07186.jpg The springs instead…[Read more]
It’s good to have control of the string length at the pulley, maybe your tutorials should include this update? For the springs – I think it’s good to keep the strings under tension – great pictures and nice cabeling! But e.g. a bit of a fragile object might still be broken because the servo won’t stop? I see you use your preferred HK servos in…[Read more]
The basic problem is that the you need to pull a longer distance in one direction that the other. For example the major finger needs to be pulled 27mm to close but only 17mm to open. So the servo pulleys needs to be redesigned to have two different lanes, with different diameters. I have started to experiment, but the pulleys I try now are to…[Read more]
@juerg, the servos won’t break parts, at least it never did on any of the hands I have assembled. In MyRobotLab you set the Min and Max for each servo, this avoids the servos to force further than necessary. The pulleys mounted on the HK15298, even though it rotates only 90 degrees, can actuate fully all fingers, only the Majeure finger is…[Read more]
Thanks for posting the spring design. I think springs has to be part of the solution, since turning the wrist will pull on both sides of the servos. A different design of the pulleys may decrease the length that the springs need to flex.
Springs will the best/easiest way to solve the problem.
I will use this Pully, including a spring to let the finger go down again. I haven’t springs at home to test, so here some different views from my drawings and a mounted pully at a servo: https://copy.com/AU86iOeAAAVYHLev
This Pully size is fine for the Index finger, when the servo makes a…[Read more]
I would like to close up the back sides of the biceps. If nobody has this in his pipeline I could start work on it.
I have added more SCAD files for creating individual parts for different servo dimensions http://www.thingiverse.com/thing:1023923
I have tried to come up with a howto about my method of finger string assembly http://snaptip.com/y4dc2d66lh/inmoov-finger-strings

Hello guys, Here are some more pictures of the new back for InMoov. It integrates a ThinkPad Tablet 8″ which can be replaced with other tablets fitting the same width size specs. A clip on, printed mechanism, makes it easy to insert or remove. Access to the two Arduino Mega and the Nervo Boards is easy once the tablet is removed. Access to the…[Read more]
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?
I got totally excited myself when finally I could mount them on my InMoov. Yes I will release them. A few little things to modify, specially where the clavi potentiometer rotates, and also the battery holder needs to go a little lower to let access to the power cable of the Tablet.
That is a really nice back. Looks good and will protect all the electronics and hide some of the servos.
Thanks Mats

The eye mechanism can be found here: http://www.thingiverse.com/thing:1035688
Great modification! I’m printing it now. Thanks for sharing the STL’s.
I added the part that is needed for the neck to part 1 http://www.thingiverse.com/thing:992918.
Great!
I’m almost finished with the head. Next step is to connect the servos to the Arduino and power supply.
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]
Hi Gael. I have a jaw servo, It’s located where front cogwheels was mounted. I use the modified neck that was designed by Bob Huston. I see now that I have missed to post the part that replaces the other cogwheel. I will do that soon. Picture one shows the location of the servo just above the speaker and picture three shows the modified jaw…[Read more]
Okay I see it now. Post a video when you are ready with it.
Hi Gaël. I think the link should point here: http://www.thingiverse.com/Gael_Langevin/collections/inmoov-parts-and-derivatives. Same problem with the link on the “InMoov parts and derivates” page and also on the “Build yours” page.
Yes thinks for pointing it out. Problem fixed.
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 😉
Just read an article about servos – it provided some insights I would like to share. http://www.rchelicopterfun.com/rc-servos.html
It’s true that understanding how a servo works is a good starting point. Though I must say that some things about servos still don’t make sense to me, ahaha. An example, why on most website selling servos, the specs rarely mention what is the maximum degree rotation a servo can achieve. It seems to be something you should discover once you bought…[Read more]
You are right – there are many missing pieces in the specs the producers or resellers provide. Maybe we could make a call for all builders to ask servodatabase for additional columns in their filter and list? I just started with a mail to admin@servodatabase.com!
Maybe a servo for the legs? (don’t look at the price) https://www.pololu.com/product/1391
I have created a small howto about my currently preferred finger assembling.
http://snaptip.com/h9quouigwr/inmoov-my-method-of-assembling-finger-parts
Clean prints in your how to! What resolution do you print with? Your requirement for drill bits is slightly smaller than mine, it varies pretty much according to your printers settings and filament supplier.
Thanks Gael My printer is a Multec 300 and I print most everything with 0.1 mm layer and 2.85 mm filament. After spending a lot of time with aceton slurry and removing/reattaching the print bed sheet I print now only PLA-HT on a “never have to change” printbed. The vertical surfaces tend to be a bit rough, I assume due to the fact that the Z-axis…[Read more]
Hi Tried to create a arm rotcenterv2.scad file that allows for specifying your individual servo dimensions. From the OpenScad.scad file you can – after specifying your 5 measures in the script – render your individual 3d object and export it as .stl. In the script you will also find the instructions how to create the stl for the opposite side. No…[Read more]
Great idea! I will add it in the derivatives library http://www.thingiverse.com/hairygael/collections/inmoov-parts-and-derivatives
Oh please use the same licence cc-by-nc when posting remix of my parts, thanks
Hi Gael, for sure, did not pay attention to that. applied the cc-by-nc to all my InMoov parts. Will start work to make my omoplate holder variable too.
3d printing with ease Please understand – I definitely do not want to create product placement in my blog – just let me tell you my InMoov printing difficulties. I first thought ABS and badly failed, nothing sticked to my print bed. Then listening and reading many experts opinions I switched to PLA. I gladly agreed because nothing worked with ABS…[Read more]
A Perfect Print Bed is like the quest for Holy Grail. All infos about it are welcome. What is the “rescue” material you finally use from mtplus? I tried so many things and materials for the perfect printing bed before starting InMoov project. Blue tape, UhU glue on glass, Buildtak, Ninja Board, ABS slurry on acrylic, bakelite and so on. I use…[Read more]
I use a Velleman Vertex K8400 printer with an unheated glass bed with BuildTak. PLA sticks well to it. The BuildTak has to be replaced about once per month. I have never tested ABS. The printer has three fans to cool down the PLA. I have to use a lot of force to break any part. It they break, you may have to little infill or to thin walls. I use a…[Read more]
Hi Mats never seen BuildTak before but the web page promises exactly what I got with my material. I haven’t touched my printbed for 3 month’s now with printing times in average probably 3 hours/day. Juerg
It looks to be kept secret what material it is. It is also rather expensive but after having encountered so many problems I gave it a try (beside other materials) – and at least for me and my PLA-HT it works like a charm. When I compare ABS prints with the PLA-HT the second is much more robust (like I can not brake the large lower arm parts…[Read more]
Buildtak didn’t work with ABS for me, I managed to nearly destroy the surface after the third print. ABS temperature is too high for the Buildtak and causes to scare the surface rapidly. I didn’t try with PLA. But I have seen very good results at various 3D print shows.
Replacement Servo for omoplate
After burning quite a few HS805BB I wanted to try another smaller servo which had interesting specs, the tgy-mg959 v2. I have added the redesigned holster which maintains the geometry to thingiverse (look vor InMoov omoplate). It should also work for rotate and shoulder and sure would look sharp on the robot.…[Read more]
Awesome good test and results! Thanks for sharing Juerg. Definitely something usefull for to make the servos smaller. Speed seems to be the same as the HS805BB, what are the torque specs?
Hi Gael Thanks for your comment. I bought it for the hobbyking statement 30kg/6v and 0.15s/6v for 60 deg. The servo I got is named v2, but you can also find other statements where only 15 kg are given. Do not know but performance looks to be acceptable and I am quite sure it could be good for other HS805 replacements. It is rather easy to change…[Read more]
@ambroise super, Really looking forward to see the video

I had several ideas when I started to print the head. The large servo was more expensive than a small, so I tried to replace it with a standard size sero. I also wanted to mount a better camera in the head than a USB camera. My modified head contains a Raspberry PI 2 with a Raspberry Pi Camera module mounted in one of the eyes. It also contains…[Read more]
wooouu, setting the brain in the skull. What sort of camera did you set in? I tested my full InMoov with the Raspi2 and was a bit disapointed with latency. The Odroid U3 was also having latency… Let us know your Rasp2 acts when you will be using speech recognition along with OpenCV tracking, so we can share comparison.
I use a Raspberry PI Camera module connected directly to the Raspberry CSI port. I has really good quality for still pictures and video stream is OK. I tried to use it with MRL and the OpenCV service, but I got some error messages. I will sort it out with the developers of MRL. Thay are all very nice, skilled and helpful people.
Others have tested the Raspi Camera module into MRL with success. Your errors might be related to which version of MRL you are using. When I tested the camera with the Raspi2, I was using version 1.1.107 and it was working fine, though with latency.

This is a part of the Bicep. I use PLA, and it's not as soft as ABS. So when I tried to mount them together, it was impossible, because it wouldn't flex. But PLA gets soft at relativley low temperatures, so I used a heatgun at a low setting to heat the connections. After heating the plastics for a short while, it was easy to mount them together.…[Read more]
Great idea, I’m sure this will a lot of builders using PLA!
I should add this suggestion in the tutorial for PLA users if it is okay with you.
Yes, please. The main reason for me to share my experences is to help other builders.

Hand and forarm printed in black PLA. I use recessed M3 screws to hold it together. I drill a 3mm hole in the part to be mounted. In the part that it should be mounted to, I first drill a 2.3 mm hole and then I use a 3mm taps to make a thread. It's not easy to make the thread straigth by hand, so I mount it in a drill.The 8mm screws are made from…[Read more]
Tabing the holes really helps, it is what I also do. Unfortunately not everyone has this kind of tools. Great work by the way!

For the fun, what if we print a big hexapod for InMoov
Inmoov looks like something from Outer Limits.
Many will need to print, but the robot will go 🙂
Sooner or later, someone will make…
yeah that is likely possible!
Gael, what about anthropomorphic legs? What if to attach the tail with the wheels to the back the of the robot. The tail will confer resistance. The wheels can spin in one direction only.

Ah yes I had seen your post, but I couldn’t find in which topic it was posted. It is a good idea of course, as a temporary feature. I was thinking of using an assisting walker for the beginning. And then when we figure a better way for the robot to walk, we could remove it. And let him fall.…[Read more]

To Fred and others: https://groups.google.com/group/inmoov/attach/151d3d256a4108f0/spring%20tensioner1.jpg?part=4&authuser=0 This is how I see a spring added to the retraction tendon. In this set up we avoid forcing on the servo either way of rotation and it also avoid losing tension in the tendons.
Have you already tried this ? If so, what kind of spring do you use, and where to buy it ? 🙂 (ok, I’m lazy 😉 )
No I haven’t tried yet, I want to order a box of various springs on ebay.
I really think this member activity stuff doesn\’t work well. But I can\’t seem to find a better way to make. I hate the videos that are cut in half. Seems also that it is difficult for you guys to post comments, because there is almost never comments on the posted pics and vids. Any suggestion about that?
I’m not really into site programming but when you go to activity the bar on the right is not needed any more. if this is removed you might have more room for the videos.
for the comments, Im looking almost every day to see what others are making. the comments are sometimes low but I think lots of people are watching.
I also found it a bit difficult to navigate the site. I just kept punching around until it functions as it should. I would also agree with dumping the update stream on the right side but leave the members activity button.
I have found that by using “copy and paste” into the text box is the easiest way to post You Tube videos.

Hi Bob, so if you want to post a video from your youtube account, you just copy paste it into the comment box?
