1130: Villeneuve Ornithopter v1.2

When I first read Frank Herbert’s “Dune” series of books, it was the mid 70’s and I was a teenager. The expansive universe captured my imagination like little else.

Dune Part 2 has just been released in cinemas, and the Denis Villeneuve adaptation is visually stunning. On planet Arrakis (Dune), a chosen method of air travel is the “Ornithopter”, described as an insect-like flapping machine.

’Thopters in the current movie series are astonishing, if illogical from an engineering perspective. Variously, ‘Thopters have 2 to 12 wings, each move independently in a coordinated buzz to provide controlled lift and thrust.

The origami world has a few simple ‘thopter designs, most modelled on the 80’s David Lynch film adaptation, so I thought I would have a go at designing one from scratch. Initially I thought to harness an existing base, but decided I wanted 12 wings, in groups of 3, and wanted landing gear, some paper for a fuselage and various flaps for some simple detailing.

There are many design methodologies I could have employed. Circle packing (each circle centre representing the vertex of a stickey outer bit), 22.5 folding to facilitate the point-splitting needed for so many separate flaps, but settled on box pleating.

First I sketched out a rough crease pattern (CP). 12 points along opposite edges of a square. The downside of this arrangement was the points ended up tiny – way too small for the wings. Rearranging them symmetrically allowed me to include extra flaps for landing gear, cockpit and more. Designing the collapse along a 2 unit strip of the central axis also gave me the bulk for the fuselage. I calculated I could achieve this with a 48 grid.

1129: Blastoff!

Grommit, you forgot the crackers!!!

Scrolling through this year’s JOISEL AWARD entrants, I noticed a lovely little Rocketship designed and folded by Zhu Yandan, from China – it was released with a crease pattern (CP) so I thought it worth a try.

I used a technique called “Ghost Creasing”, where ONLY the needed creases are transferred via careful embossing using a stylus. This eliminates the excess grid creases, making the fold cleaner.

Lunar

Fueled up and having an extra sheet of tissue from the shirts I bought yesterday, I set about being more deliberate in my crumpling.

First up I scrunched the sheet up tightly and randomly, then flattened it – I regret not doing this on the previous square field crumple as it helps refine the end texture I found.

Next, I chose random bits of crockery of different radii, placed them in an aesthetic grouping and then gently eased the paper around the different circumferences (to mark the circles is all). I then removed the china, flipped the sheet and set about HARD creasing the circles.

Next, I gathered all the sharp circle creases together, encouraging the remaining tissue back, away from my gathered edges. I did the same for the smaller circles and brought them together with the large circle edges, then hard crumpled everything (like seriously squished it) back away from the circle edges.

1123: Anubis

I have always been fascinated by Egyptian symbology, myths and ancient artforms. The very pictorial style is angular, stylised, often animal-based and very interesting. Anubis is the god of funerary rites, protector of graves, and guide to the underworld, in ancient Egyptian religion, usually depicted as a canine or a man with a canine head:

I am currently watching STARGATE, a few episodes at a time with my son. I began watching it back in the days of free-to-air broadcasting but, for whatever reason I stopped (prolly because I had a life and no longer had time/access to episodes). The series premise is interesting, and I particularly love their hijacking of Egyptian gods/mythos as the “baddies”, as well as the whole aesthetic.

I wish I could remember where I first found this Crease pattern (CP). It has been in my “must try this, sometime” pile for a couple of years and I finally got around to it when looking for something to fold with my second bit of treated Wenzhou rice paper (not made of rice, is a fine and resilient mulberry). I also wish I knew the designer – can anyone help me out here as I would love to give proper attribution?

The CP seemed pretty straight forward – indeed the collapse was quite natural (I did not do my usual “parachuting” as I tried to collapse key details in the order that seemed most logical), and resulted in a base with a myriad of stickey-outey parts in more or less correct locations. I am so pleased with my developing CP solving skills – a loooooong way to go, but every success encourages me further.

1107: WALL-E

Although (technically) a re-fold, the last time I attempted to fold this I had a partial crease pattern and a broken incomplete set of instructions in Russian, and just muddled along. I am not sure the resultant model even looked like Wall-E, but I was happy to sort of nut out a scheme for making his tracks.

I stumbled across a set of partial diagrams by “Tosummerny” in Chinese that seemed to surface more of the actual process, so decided I had to have another go.

I went big – 90cm square – seems excessive …but … I have another exhibition pending and thought this might make a good display piece if it ended up tidy enough.

The diagrams clarify the construction of the pleats necessary to form the main body, and how they cleanly articulate to make the beautifully treaded tracks, and also simplified what I had in my previous attempt mangled together to form the eyes.
