Steampunk auto-folding wings

Featured
I have made for my daughter steampunk wings which can fold open and closed with the help of Lego Technic parts.

I was running out of time for the "make it real" contest, so I posted this instructable before I am all done, with the intent to improve/expand as I go... I have not yet been able to do the fabric on the wings, but the rest is done and working.

This is my first instructable, so bear with me as I tweak my style...

So where do you start? You find wings you like that fit the style... Leonardo DaVinci was a prolific drawer and researcher of wings, so I started with looking for images by him, and found one that my daughter liked and looked doable...

Finally, what would I do with the printer? It'd print the parts I used and make them look more Steam Punk and less Lego... And then more, obviously.
I'd also like to start a little 3D printing workshop to allow others access to affordable 3D printing...

Step 1: Design the mechanism

I then designed the mechanism for the wings in Lego Digital Designer, and subsequently built it for real to test whether it actually worked...

Step 2: Transfer the design to the wings image

Satisfied the mechanism worked I took the measurements of the Lego mechanism and transferred it to the image from DaVinci and then I printed it on 1:1 scale. After that I drew the actual shapes on the drawing and then transferred those to foamboard to create a real size prototype.

Pretty cool Cesco, I voted for you!
And thanks for uploading the vid.

You're welcome! Thx for the constructive criticism and for the vote! (I can definitely use more of the latter! )

And hey, it got an email telling me it's featured in the Technology section! Flabbergasted! Esp. as it is my very first Instructable, and not even finished yet!
Is there a website one could go on to get the lego pieces?
do you think it would be possible to use springs and a latch to make the wings jump open rather than using electronics? or is the system too delicate for that kind of jolt
CescoAiel (author)  captainjazzhands1 year ago
As long as you don't use springs that are too powerful and tighten the nuts accordingly it should work... (I think!)

Hmm, for some reason i can't seem to reply on your post... So I'll just repost.

OK, thanks.
That might be a bit small for me, so i'll probably add an extra foot. To bad the engine won't hold up, it was an nice solution (everybody has easy acces to lego's).

I also thought about using gas pistons and then linked to the small 12gr co2 canisters. I haven't found an affordable piston though.

I think it also depends what you want to use for the wings... Wood is relatively heavy... So is cotton fabric...

If you were to use lighter materials (aluminium, fiber/resin spines, nylon fabric, etc.) you might still be able to get away with using the Lego... Perhaps adding springs to take some of the load (esp. when extending the wings, which is clearly the heaviest task for the motor) may help as well...

PS: The main problem is not the motor (and if it were, Lego also has a bigger one, although that is a bit slower too), but the strength of the plastic cogs, esp. the really small ones, as well as the cohesion of the frame they're mounted in (the 'bricks' come apart which cause the cogs to slip).
I chose to not glue anything together, so it can be repurposed... I think that using glue and resin to reinforce the cogs and stick the 'bricks' of the framework together would also increase the load they can take!

oh my gosh i LOVE this!! i want to make one but can you please post a little more on the motor and how you attached it?
CescoAiel (author)  buzzthud1 year ago
Sorry for not replying sooner, but I have been (and still am) too busy to do any crafting or instructables updating!

I have pictures for another instructable (a steampunk reactor/powersource) ready, but no time to make it...

I'll try to make pictures and post them though... Not giving an ETA tho!

I love this build! (consider it stolen for my own set of wings).
One question though (well 2 actually). What was your wingspan, and do you recon the little motor could handle more (and thus a heavier weight)?

CescoAiel (author)  eduard811 year ago
Wingspan is approx 5' / 150 cm when expanded... And the Lego already struggles (already replaced some broken cogs!) with these, so bigger wingspan would very likely not work with Lego.

I have looked at using either pistons (but that requires a source of pressurized gas/vapor), which would be more true to the theme, or electric linear actuators, but the (10V-12V) ones that have sufficient range (IIRC approx 14cm or 7") of movement are very expensive...

Cool

Coll I may build this
A very nice project! The idea and the combination of the LEGO Software, the LEGO itself and the DaVinci Wings are great. Looking forward to see more...
Very cool, excited to see the completed project

So am I.... So am I! ;)
CescoAiel (author)  CescoAiel2 years ago
Almost done now!

A few more pictures and a videoclip to be added, but over all, the project itself is finished!

It's a shame the photos are so dark, but what we really need is a video of them operating!
+1 on video!
CescoAiel (author)  megaduty2 years ago
As I mentioned, I had to work with the pictures I had on my PC and iPad. I will definitely get better pictures (and a video) as soon as I get back home end of this week...

Better pics and video added...
