Printing another InMoov, because the original is going to stay home. It is a precious robot now! Having a second printer makes it fast, specially because I updated the firmware to Sailfish on the CTC printer. I used to print on Kapton with the ABS but finally got to print directly on glass which is giving a super result and surprisingly absolutely…En afficher davantage
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.
The slurry is almost totaly liquid. It’s hard to say how much percent of ABS and acetone. Maybe 20 to 30 percent of ABS for 100 acetone.
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

My printer is out of work for a moment… Gee what a smell, if you ever get your heated bed that burns out, you need to ventilate your workspace!! It took me a while to find a heated bed this size in Europe . 300x200mm. I finally ordered the PCB in Danemark.
wouaaa it is hotttt lol amazing
Oh yeah and it smells really bad in my workshop…
i can t think it is possible and so so dangerous
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…En afficher davantage
@Geal I guess it’s beause your heating bed’s temperature sensor have loose from your heating bed!! I suggest you check complete all your 3D printer’s switch, sensors to prevent this happen again…

This is awesome! The 2 topmouth pieces have always been kind of a pain to work with, so that will help alot.
Yes indeed, I also did a reprint with fused topmouth after coming back from India, the head had been damaged in the suitcase during flight travel. It is much easier to assemble now.
Well it took me a while but it is done!
New builders will have a lot more fun to assemble the skull now. I have set screw and bolts holders in various parts to make the last fit much easier. You can use 3mm screws and bolts to attach the parts together. I modified: -TopMouth -SideHear -LowBack
Ahhh, great, I had started to add flabs n stuff to keep them from falling apart.

I’m almost finished with the mechanical build and the testing of each servo individally. Next step is to purchase / build and install all the electronics and batteries. The back is still a bit empty.
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…

I get about 2 FPS when doing facetracking. That is good enough, however I also get 5 seconds latency, and that a bit to much. I have tried using the camera outside MRL and I get good results from the camera. I can stream at about 30 fps about .2 s latency. That is good. I had a problem that took me some time to figure out.

I would love to have this on my desk, I only have a head so far, and that’s controlled by LEGO
I also realised some time ago that using the latest version of MRL which uses OpenCV 3.0 that I would get a low fps result. I was recently mentionning that to Grog and he said he would digg into it. So, using the Lenovo tablet touchpad with the version 1.0.107 gets me with a a fps of approximately 30. Using the version 1.0.954, gets me to a 7/10 fps.

Small video to explanation the driving system of my plateform and the locking mecanism for to be able to push InMoov by hand while driving direction with the remote. I\’m in the process to make a very small remote transmitter which could be held within the palm.
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.

Hi everyone! I uploaded all parts for the new eye mecanism inspired by Mats Onnerby and Bob Houston. The mecanism is more sturdy and gives wider degrees of rotation for the eyes.

Awesome Gael and thanks for the files and the tutorial.
Thank you Gaël , i cant wait to start the head !
Last night InMoov had something of a Picasso painting… Modifying the eye mecanism to adapt a mix of Mat and Bob to be able to use my previous face design along with the Hercules camera and the DS929HV servos.
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…En afficher davantage
Well the hercules HD does a good job as far as what I do with it. But as I said it would be ideal to have a board for post processing things like tracking, face tracking, object color detections to let the computer do other tasks. The Pixy camera would be great but it is mounted on such a big board…
I will wait for this camera: https://openmv.io/ Leon has ordered them via kickstarter 🙂 This has the same results and is smaller ! I hope the price is the same like the Pixy cam.
The Pixy already used a 4-layer PCB, so it would be a hard work to make this smaller 🙂 Option is to ask for a sort camera-shield mount option.
I use the raspberry PI camera in one of the eyes of the modified head. It’s much better quality than a USB 2.0 camera. And the intention is to use the Rpi to do image processing. You can even find a really small version of the camera. https://www.pi-supply.com/product/adafruit-spy-camera-raspberry-pi/
@Marten, As you mention in private message the OpenMV could be a nice option because it is python based and Open source which could be easily added to MyRobotlab with no need to use an extra Rpi. @Mats, I personnaly would rather a smaller device than having to use a Rpi for the image processing, because with the tests I did using the Rpi the fps…En afficher davantage

The new dual track servo pulleys interfere with the cover of the hand. If you use them some material needs to be removed from the arm cover to make room for the front middle pulley. Thanks to Juerg who warned me that this could be a problem.
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…En afficher davantage
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
I’ve seen the video and the results are perfect ! The option was more meant to update the Pulley’s for other InMoov builders, how like to use your Pulley’s, so they haven’t to cut anything 😉
From a math point of view, an excentric pulley will work very different. With two tracks, it’s just linear movements. The excentric can only work between very limited angles. With two tracks, you can rotate any angle. The ratio will still be the same.
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!
😀
Sorry forgot to ask if this solution need a different MRL configuration, if so can you be so kind to explain changes need please? Thanks again!
No change to MRL, except that you may have to change the max and min values for each servo that controls each finger, but thats someting you probably will need to do anyway.
Nice, thanks!
I added a new video to show the difference between the original servo pulley for the hand, and the new dual track pulley. https://www.youtube.com/watch?v=b5S-8hjsMr8
Ehi Mat, thanks for sharing! I will print one to test on a finger starter kit to see the effects.
A litte update to expain the reason that I redesigned the servo pulleys. I use the fingerstarter to explain. In the first picture the hand is open and both lines are stretched. On the second picture the hand is closed, but the lines are not stretched any more. To close the finger the servo pulls about 27mm and releases 27mm on the other end. But…En afficher davantage
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.
hi mats Maybe I see things the wrong way but I do not understand why you have to modify the pully. Set your servo to the middle position than add the pully with a 10 mm offset towards the closing side. In MRL define a mapping that covers the 44 mm range for the full movement with your servo?
Hi Juerg. Please post some pictures or a video of your solution.
Video of testing the new servo pulleys for the hand. https://www.youtube.com/watch?v=gwx3JIakDV0
Very good idea the « double pulley ». You get the same results for the pinky and middle finger ?
Almost. Even if the pinky moves a shorter distance than the middle finger, the ratio between opening and closing seems to be almost the same. I only use one pulley size for all fingers.
Very good idea!
I have made new servo pulleys for the hand. They have two tracks with different diameters, since you need to pull a longer distance to close the hand than to open it.http://www.thingiverse.com/thing:1074604
This looks interesting – How would you describe the improvment to the hand’s movement?
To close one finger you need to pull 27mm but to open it again only 17mm, The 10mm in difference will result in that the lines easily fall out of the tracks, The servos will also have a deadband of 10mm before they start to pull, With this construction the lines will be stretched all the time, so the fingers will keep their position better.
The reason I am asking is if you think the springs that were introduced to keep the strings tight would still be needed ?
Good question. I don’t think that springs are necessary, but if you turn the wrist, the lines will be tightened. So you have to compensate for that by relaxing the tension on the lines a little,
Hi Mats Can’t really see why you want to modify the pully. Put your servo to middle position and add the pully with an offset to the closing position that will account for the different distances for opening and closing. The use the mapping feature of mrl to adjust the overall distance for your servo in use?
I posted an update to explain the probem.

Good idea, Gael, about an adjustment to prevent cross eyes. I have designed a new part that will allow for that adjustment. I have added it to the STL’s on Thingiverse.
Ah perfect! Hey but you can add comments? So it works now for you the community?
Hmmm, that’s strange that it shows up here but I can’t see my comment on the main Community page
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
First test of the servos. The neck works fine. Jaws needs to be changed to increase the speed of movement. Eye servos tested but not connected to the eyes.
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.

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.

It also contains…En afficher davantage
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.
