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…[Read more]
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…[Read more]

Nervo Board Hello Gael Do you know when you will ship my Nervo boards? Money went from paypal on 9th October but I have heard nothing, the shop says on backorder now but didn\’n when I ordered.
Thanks Richard
Hi Richard, Nervo boards have been shipped with a delay because I didn’t have anymore XT60 connectors. The shop had a malfunction which should be fixed (Thanks to Sebastien) because it changes from “backorder” to “in stock” everytime somebody would purchase a Nervo board and vice versa. But rest assured that it’s on the way to your address.

And here the video again (First post seems not work on InMoov site)
Awesome! Nice progress! After testing myself the Oxboard in my workshop, I am amazed how human body can adapt itself to an unbalanced engine in such a short time. By the way thank you for sending it to my workshop! I am wondering how InMoov is going to balance itself on that engine though. It seems even more complex when having the robot standing…[Read more]
We’ve already bought an Heading hold gyroscope (as used on model helicopters etc.) and will experiment with it trying to find balance. But I agree, it will probably be difficult to achieve. We also want to control both servos with one joystick. I saw already some sample-scripts, so that’s more likely to succeed. We will keep you informed.
Hi, A few weeks ago my son Wouter and I showed you are planning to let InMoov drive around on an OxBoard. It seems to work out pretty well! 1. First we constructed “nice, skinny legs” from pipes and Key Clamps. (See picture 1 below) Only the ankles are moving forwards and backwards using two servos with pistons. (See picture 2). The actual pos…[Read more]

Hello,
here is the first video of “Hansi” with working Torso and Head
very well finished and alot gone into the finish of the parts by the looks of it. i like the led lighting effects. how did you achieve that, especially the eyes ?
i make this FX with NeoPixel Ring.
12 LED NeoPixel for the Head and a 24 LED NeoPixel for the Torso
Noticed that your shining Hansi talkes and understands German. Are you controlling it with MRL? If so could you provide details for the setup?
Yes Hansi is understanding german, but i use a EZB4 Controller to do that.

Grüße Boris
Wow. That’s a high quality build. You must have spent a lot of time to make the parts look so good 🙂
hi rentaprinta how did you mount the neo pixel in the head and where ?
Nice video Boris! InMoov lights up for Christmas time!! it’s nice when InMoov starts to talk through program isn’t it? I heard you had to use keyboard typing during the Berlin Makerfaire instead of voice recognition, in fact I met Bodo Facklam in Roma.
Hello Gael,
yes the Inmoov can make now some christmas atmosphere 😉
My girlfriend is using the keyboard to write sentences to give better answers to the people. Normaly the Inmoov had some random programs who are running. But to give a answer to a question what he did´nt know, we must use the keyboard.

Tip i used to print special parts without support like this . Epoxy glue and hotted metal nail inside
Still printing, but all looks good to me: https://copy.com/7NkaxvRHL1W64ZKo
great Marten ! i will try reduce print speed with 100% infill . 226° is not too hot ?? I use simplify3d no Wall Thickness settings just perimeter shell .
Hello Anthony,
226° is a high temp, the UM2 has a lower temp as the display is showing. And with this temp I get good results 🙂 Sometimes I set the temp a bit lower, after the first 10 layers.
Do you have a picture from your end results ? If yes, it good be handy to give a better advice where it go’s wrong.
I checked the K8400 and see there…[Read more]
ok I start at bigger temp too it better to attach bed . This is it : ( the middle is already glued ) : http://lerendezvousdelaterre.com/tmp/piston_cut.jpg .
Looks good Anthony, I think only you need to start the fans from a higher layer ! I see a lot of warping at the bottom side, this happens when the PLA is cooling down to fast. The best way is to start slowly with the fan speed around layer 30 (3mm if you are using 0.1mm layer)
Also check that the print bed is close to the nozzle. If the distance is to far, the first layer will not stick well to the bed. The first layer should create a solid piece of plastic without gaps.
i also printed all the gears and pistons in carbon fiber/abs, very strong and light and durable.
It is interesting to see how 3D printers have improved in 3 years. When I started the project, most printers could only print with raft which would have been a pain when assembling together those two piston parts. Today with heated bed and good sticking surface it becomes easy to print parts in different directions. Also support printing is so…[Read more]
Yeh u r right, i remember it’s like old paper printers 🙂
I need to improve cooling, sorry the fishes for the hack i try something : air-pump flow ( i need better pump, flow is not strong enough ) : http://lerendezvousdelaterre.com/tmp/aqua.jpg
Yeh I remember it’s like paper printers ! This is support killer : I dont need glue anymore but 6 hours … 🙂 Print is perfect 80% infill inside http://lerendezvousdelaterre.com/tmp/support-killer.jpg
Mats Önnerby posted an update 10 years, 2 months ago
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…[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
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!

Hi robots it’s for your own good ! Intensity sensors . The problem is if we want monitor all the servo , there is lot of wires…
I hope this will give the option to monitor each finger. As you can see, the value isn’t straight (it’s now a pulsed signal) because of the 50HZ servo position update/feedback timing. I think we need something like a RC (Resistor/Capacitor) network, to filter the 50HZ to a constant…[Read more]

@monnerby Hi mats Currently on vacation in Japan (they have some nice robots here too but InMoov is not popular here). I can’t draw you a picture with my mobile but look at this – the servo has to travel 17 plus 27 mm for complete opening and closing. Depending on the servo you have installed (my mg995 can do about 210 degrees) this will be…[Read more]
Hi Juerg. I appreciate that you want to help. But from your answer, it is obvious that you don’t understand the basic problem. It has nothing to do with centering the servo. The servo needs to pull 27mm on one side to close the finger, while releasing 17mm on the opposite side. That is a difference of 10mm. Not a sum of 27 and 17. To open it…[Read more]
Hi Mats I think I got your point. When doing my first pulleys I had problems that they interfered with the cover, adding a second track would require lower built servos or a modified servo-bed? And the string-guiders will need to be adjusted?
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…[Read more]
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.

This is Kim looking at her new head this is a combination of monnerby head and bhouston eyes I like the jaw and neck movement of monnerby’s design and the eye movement of bhouston’s design, Thanks to both of them for sharing their files and of course thanks to Gael for all of his help and vision .(note the logo on left shoulder)
Very nice picture, oldfarmhand. It would be really great if you could post a video showing the difference in movement between the nominal and monnerby heads. Barring that, how would describe the difference?
more room in the head due to smaller servos, smoother eye movement,smoother mouth movement, more room to put speakers and microphones, less parts in the neck due to no gears, overall just a lot more room to add other items
Oh, is that all? :^) I’ll have to take a closer look at it as I would like to put an amplifier in there for the ear/speakers.

Hi Kenneth. Really nice to see that you spent the time to reprint the head,and that you like the result.
Hello InMoov Kim!! very nice looking prints!

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.
