London 3D Print Show was very interesting. It was a 3 days
event, so plenty of time to demonstrate, meet people, talk a lot, to the
point that my voice started to change at some point. And the
robot didn't brake any printed part, but I burned 2 servos. The reason,
in the right arm I'm still using the first version for to attach the
servos, and the wires got tangled between themselves and caused an
overstress. Smoke came out of the arm + an awfull smell, very easy to
recognize. Unfortunatly I had no more spare servos because I had
used them for to demonstrate the Leap Motion in another printed arm.

InMoov will be presented for the 3D Print Show in London and Paris. London 7-9 november, Business Design Center Paris 15-16 november, Carrousel du Louvres.
I do keep myself busy lately... A bit too much in fact.
Make
is organising a big robot hack and InMoov is involved. There should be a
bunch of hangout sessions. This is going to be fun!! Chuck Fletcher,
who presented his robot InMoov to the New York MakerFaire is going to be
part of the sessions as well.
Here is the link to the article.
Okay, as I said before to go to Roma, parts for the rest of the Torso are ready for download. This includes the surroundings of the kinect and it's casing. You will need a whole bunch of parts which are added to thetorso CubeHerodownloads.
Four days of geekiness with Makers from all over Europe! It all went very smooth, no problems with the flights and InMoov arrived safely. No broken jaw or shoulder. It was pretty intensive, but what a great time. I meet Leonardo (who's made this website) and Alessandro (Ambassador of MyRobotLab), and we shared some unforgetable moments.
Wow this is it! Tomorrow we are going to Roma to present Inmoov at the Europeen Makerfaire. I'm pretty excited, hopefully everything will go smoothly, starting with douanes and the airports.
3D printing is a major concern for the authorities since some fools printed guns, now any printed stuff can be potentially a weapon. Since you could print a Makerbot rabbit that works as a gun, who knows what form a gun could take. Anyway, I really wonder how this is going to be evaluated by the "douanes".
As you know Inmoov is filled with cables, motors and batteries.
Hopefully when they open my suitcase they will see a robot and not something else. How does this looks to you?
Thanks to Leonardo, we have a superb website which will let us get more features then the blog. Leonardo,
an Italian InMoov builder in his spare time, and a great musician, has
been working since june to get this up, it has been a long task because
every pictures, every tutorials, every posts had to be copied or linked
to the site. He has created a set of tabs with more functions and sub-tabs. A new look to get easier access to whatever you look for. One
of the main reason for to move to a site was a to be able to upload
builders creations. For that we needed space on servers allowing us to
store data. Leonardo is also going to the Makerfaire in Roma with me and he has uploaded his videos and pictures of his InMoov. So make sure to check the Community tab and start to upload your creativity.
I
will be closing the tabs of the blog when I'm sure everything works on
the Website correctly, there is no point to keep everything double.
I was away for a while, and of course when I travel, I don't cary my 3D printer with me. Plus, being away in the desert makes it difficult to comuunicate with internet. Since I released the finger prosthetic for Bionico, I was impatient to print it. Fortunatly Morris, on the other side of the Atlantic had his printer ready for testing. He was the first one to print the finger and got me some feedback. You can see his blog here So I was designing on my computer in the desert and he was printing the parts along, and everytime some thing was not correct in my design, he would notify me and I could check the pictures posted on his blog to modify the design in consequences. This took us a lot of time after all. But we got to move on and thanks a lot to him. The three bellow pictures are from his blog:
Being back from the desert, I was then able to print the finger. There was still things that were not correct. I also ordered another type of motor which is a 6V planetary gear motor with a ration of 154:1 from Pololu. So the casing had to be redesigned again. There is a very small worm gear that actuate the finger and I printed it in ABS but it is definitly too fragile, so it either needs to be modified or printed in stainless steel. You can get it by Shapeways here.
I left both versions on Thingiverse because it can be handy for other projects.
With the servo Corona DS238HV use these files:
-FingerWormV1.stl
-ServoHolderV2.stl
-PhalangeV6.stl
-ActuatorsV3.stl With the planetary gear motor use these files:
-FingerWormV2.stl
-MotorHolderV3mid.stl
-MotorHolderV3top.stl
-PhalangeV6.stl
-ActuatorsV3.stl
It was pretty hard to make that video, because the small wormgear breaks when the finger reach the end of it's run. Unfortunatly I haven't yet figured out how to set a time delay on my script and a reverse of polarity. Using DC motors and servos is not the same when it comes to create a script in the Arduino. The big news:
InMoov is selected and invited for the European Makerfaire Edition in Roma. So I will be going to Italy and have the pleasure to meet all the italian and european geeks that attend this event. I hope to get some time to make the robot usable, it's going to be something to put the full InMoov in a suitcase. Myrobotlab is also selected to attend the Makerfaire, Alessandro will be the Ambassador of MRL. Leonardo who has created a superheroe InMoov will attend the faire as well, hopefully his suitcase is big enough for to bring his robot. Leonardo his also working to make us a real website. And Bionico, of course, is also selected for the Makerfaire, we are currently getting a hand ready for Nicolas. Hugues is hard at work on all the stage levels. Here is a french article about us in LE MONDE newspaper.
