Iron Man 3 mark 8\42\47 faceplate mechanism

Hello everybody! I have a bit of a quiestion. There are a few videos on Youtube that demonstrate the hinges setup for the faceplate.
I noticed that it is not as simple as mark 2-7.
Here is a picture that demonstrates the actual behavior of the parts:

As you can see, the first thing that happens is that the jaw extends for about an inch and only then the faceplate rolls up (this order is just a proposition. Both action may be performed simultaneously in the movie).
So the question is: How the hell is it possible to mimic (there is NO other way to open the helmet if it is designed 100% movie-accurate)? My thoughts are maybe using some pneumatics or hydraulics (this option is not actually an option because of size). Or maybe some axis as there is enough space for a small motor in the ear section.
The subquestion is: If the faceplate moves forward WITH the jaw and only THEN rolls up, the rolling mechanism cannot be attached to the forehead. This is also a great puzzle to me.

Any suggestions?

I just had a quick thought, you could have the faceplate and jaw linked so when the faceplate moves up the jaw will drop out, then as the faceplate comes back in the jaw will close. from there I was thinking you would only need a motor for the faceplate, since the jaw will just be pushed in and out with the faceplate motion. not sure how to go about the mechanism set up though. I am also working on the mark 6 helmet where there is four simultaneous movements, so if you need help just hit me up.

The jaw has ALWAYS moved on the movie helmets. (Through the magic of CG, no doubt) It just hinged at the cheeks/jaw, rather than at the ears before.

I believe at least one person created a Mark III-VI version helmet with a motorized jaw in place. I seem to remember a video of it in action. Have a search around, we tend to share most of our finds, so if you can find that thread, you may find the what mechanism that member used and be able to borrow some ideas to make this slightly different jaw hinge work for you.

Off the top of my head though, I'd say putting the jaw on a track and using a cam to push and pull it along that path would probably be one of the simpler options. Either that or attach it to two uneven "arms" and motorize one of them. (I can draw up that latter idea if need be because it would take forever to explain in words)

Good luck.

These areas are the problem/point of interest I assume.




The Nickfox has the right idea. You want to mount the jaw on a sliding mechanism. Use whatever you like. The sliding parts out of filing cabinets/some drawers work great. Instead of a cam, a gear and a rail with a thread (like a screw) or with teeth would work. once you wire the servo up to the faceplate hinges, you can work out how long/how many teeth are needed to time the jaw correctly with the faceplate. Here are some vectors I drew up:

A drawing would help a lot! At least I hope so)

I know that jaw has always moved, I've seen the movie thousand times) But it's quite easy to make it move along a curve. There is no problem. But in this particular case the jaw SLIDES forward as you can see. And I dont see any chanse to implement this movement with a servo as there is just no place for it inside. The type of movement is different so there must be another driving gear apart from faceplate servo

Thanks a lot! But in your design parts have different movement types.

As I presume the jaw won't be able to move forward without the faceplate (design issue) and the faceplate wont move up until they both slide forward!

I'm discombobulated))

Timing is key. Get the mechanism working, then work on timing it correctly. you might have to use 4 servos.

Ill slap together some animations and see if this will work tomorrow morning.

Here's a really rough mockup of what I'm talking about. It's what's known as a four-bar linkage.

...I'm not sure it it would actually work in the manner I think it will, but strips of paper, and some brass brads used to hold paper together should allow you to prototype the movement for next to nothing to get the positioning and arm lengths down. (And whether or not to include a bend in the front arm...my gut says it'll be needed)

Would be great! Thanks a lot for your help!

btw, Jay May (hope you know who he is) just said that there is absolutely no need to slide the jaw.. My perception of 3d space a little bit corrupted after that statement, but I think he knows what he says.

Anyway, concepts and advices are welcome! It would be nice to do a movie-accurate prop if there is a way to do it.

Thank you, I think I got what you mean.

One of my latest ideas is palcing a motor in the chin (there is enough space) and route a string on the inside of the jaw to the ear section. And place on the end of a string a "rail with a thread (like a screw)" which will twist the jaw in. And out I hope..

not motorized...its manual open..the jaw not extended,face plate pull out first then roll up....i just make it simple way:)

Perhaps like this?

Thank you, but I think it won't work.. There are a lot of intersections in the cheek area. This is exactly what I was talking about. If the faceplate's thickness corresponds to the reference then it will stuck. It HAS to move forward before rolling up in case that all the details are recreated. Changing position of a pivot won't help because it will probably stuck in the chin area then.

Btw, there is a decision for IP helmet if someone is wondering how to solve opening problems. Its a faceplate thickness trick
