Webb Origami Design Challenge

Our Project

• Our team members have diverse skills and experience:
• Origami crafting
• Internet-of-Things (IoT) programming with Raspberry Pi

​

• We all are WOW-ed by how the James Webb Space Telescope (JWST) uses origami-like folding and unfolding.

​

• Our goal: Making computerized origami models for JWST
• JWST’s deployment process looked like a Jack-in-the-box for us!
• So, we decided to replace “Jack” with “Jimmy” for our project name,�respecting Mr. Webb, who supported many science projects at NASA.

Origami Crafting for Primary & Secondary Mirrors

• Customized an existing hexagonal tessellation strategy (by Eric Gjerde) to make our model more similar to JWST’s primary mirror.
• Made a hinge-inspired craft to model the secondary mirror’s folding and unfolding mechanisms, w/ a paper tape, plastic straw, glue and bamboo skewer.

Origami Crafting for Sun Shields

• Folded “long” hexagons and stacked them to model JWST’s sun shields.
• Used sheet protectors as origami papers and slung five layers of them between foundation bars with strings.

How to make Our Shield

Turning Origami Crafts to Internet-of-Things (IoT) Device

• Wanted our telescope models to actively do something, not only�being viewed passively.
• Integrated a Raspberry Pi (or Raspi; credit card sized computer) with origami crafts, so our model can do what the real telescope does.
• Our computerized origami models
• Take pictures with cameras and push buttons.
• Keep track of the current location (latitude, �longitude and elevation) with GPS receivers.

Circuits and Cloud DB App

Python Apps

• Made 3 circuits to wire up a camera, �a push button and a GPS receiver.
• Set up a cloud database (Kintone) app to store data from a Raspi, convert meters to feet and show a stored location on Google Maps.

• Periodically takes a picture, gets the current location (latitude, longitude and elevation) and uploads those data to Kintone.
• Detects that a push button is pressed, takes a picture and uploads it to Kintone.

Future Work

Prototype Models #1, #2 and #3

• Set up a Web page with videos, diagrams and code to help anyone�interested reproduce our origami crafts and IoT telescope models.
• Come up with extra tessellation strategies for origami crafting.
• Use extra sensors such as gyroscope and magnetometer telescope models
• Study how origami techniques can solve other challenges in space; Can we fold and unfold ISS modules, complex satellites or even houses?
