I'll share some of my experiences so far with InMoov and MRL lab here.

I came across the InMoov project about 18 months ago and marvelled at the videos on Gael's website. I knew that I wanted to attempt to build one of these, the only problem was I had no 3D printer. Building one looked out of the question at the time as well so I shelved the idea.

A few months ago at work a colleague raised the idea of buying a 3D printer. As the IT Admin I was roped into giving advice even though I'd never used one. After a bit of shopping around I found a company with a couple of ex demo Makerbot Replicator 2's for less than the price of one machine.

Needless to say once they arrived the idea of InMoov popped up again. I now have the use of 2 machines every evening, weekend and holidays.

It has been a fun ride so far, I've had about a 50% failure rate on my prints but learnt loads in the process and I'm now fairly confident that they will turn out acceptable.

So far I have almost completed InMoov's head bar the ears and jaw servo and one fore arm. I have most of the torso done and boxes with biceps and shoulder parts.

The head originally screeched badly on rotation due to me missing the part about greasing it. I found an excellent clear spray grease that was thin enough to soak into the moving part and dried coating them with PTFE, completely silent now.

The eyes have been tricky I bought a couple of very cheap USB webcams and tore them apart. Once they were exposed the light shining on the back produced a wierd pattern over the picture, so I experimented with building enclosures.

The first was too chunky and kept hittng the inside of the skull

The next ones worked better.

My whole eye assembly is wonky though. I couldn't get the screws into the two holes closest to the eye piece. In the end I melted PLA and tied to weld it together with limited success. As a result only one eye fits in at the moment.

Well Done ! 
Lovely post, pictures, descriptions, experiences !  Thanks for posting bensonofjohn.

There certainly are a wide variation of USB cameras.. 
Kinect is hard to beat, both on frame rate and the huge fact you can get depth info from it.  But I guess it looks to Daft Punk in the head :)

Hi bensonofjohn!

  You might find interest in the camera holders that I did up a while back to hold the hercules hd twist cameras.    http://www.thingiverse.com/thing:339283  

  If you happened to use the same cameras, you could use these with a very cheap fish eye lens.  

Nice post!  Keep it up!  I've had a lot of failed PLA prints for one reason or the other.  Some parts, I just move around or rotate a bit and they tend to print out ok for me.  

Best,

Hi Kevin

I did look at your camera holders a while ago when I was still deciding what cameras to go for. In the end I went the cheap route and bought a couple of usb ones from ebay at £3 a piece. They are okay for my current purposes and smaller size picture means I don't need pyramid down. I did try a secondhand Microsoft life cam, but once I figured out how to get inside the thing I realised there was too much circuit board to use it.

My biggest problem with PLA was warpping, the weather here in the UK took a long time to warm up after the winter and I was using the printer after hours at work which meant the heating was off. Many of the first pieces were like bananas. Generally the design of InMoov means that the pieces still fitted together just with gaps. The only pieces I couldn't join up were the pieces that go round the ears.

Evenually I got a heater to stand in front of the printer and blast warm air at it to form a sort of heated bed. I then reprinted the whole lower skull as one piece including the eye section and the servo holder for the eye up/down mover as I couldn't get a screwdriver in there to hold it all together. The end result is much better and just fitted on the print bed.

Lower Head One Piece

I also printed the gear holder as one piece, as you can see above I had great fun trying to get it inside the lower skull.

I'm interested in the work you have been doing to extend ProgramAB it integrates with MRL and InMoov much better.
