11/09 Day 1 explorations

Origami folding exercises

Bonnie showed us how to make a standing box, I happened to pick a piece of pink paper to do this

Since the pink box looks like a bunny rabbit, Kellie drew the bunny face on it ;-)

I started playing with squeezing the box to make the “ears” move –

Found an instruction page of this sanbo box -

Inspired by Bonnie's turtle with bee wax impregnated fabric

I decided to follow the instruction to fold the turtle with blue origami paper

(Appended the diagrams on 11/17, John Montroll's Origami Sea Creatures)

Continue folding all kinds of things:

folding unfolding the fortune teller

ponder where to light up when edges touch (then saw Brooke used chibitronics and copper tapes to make it work)

I played with folding a crane using the metal mesh, and some more modular origami

a Chinese vase

Meanwhile, Kellie is folding tulips

She populatted her pond with lots of frogs

how about some frogs coming out of the vase?

We wanted to animate the tongue of Kellie's frog - Daniel said, Nitinol wire.

Kailey made a horseshoe crab

11/09 Day 2 explorations


While tearing papers, strips were created. I was fascinated by the simple folded paper that can create caterpillar or inchworm movement. The form of the caterpillar could be a concave high arch with all mountain folds, or with the head and tail valley folds, or the shape can be modified/cut to look more like a worm.

Asked Daniel how to animate the caterpillar, he suggested we do Nitinol wire to animate it.

See Kellie's post, tried out with the wire on paper, and on felt (wire melted some felt)

Meanwhile, I started making a different caterpillar, using the tissue paper, and folding green papers as leaves. Kellie demonstrated adding water on twisted tissue paper or straw wrapper would make it move.

Fun to play with seeing the paper caterpillar moves up and down on the leaves.

Box Bot

With a couple modular origami boxes created, I also created springs using interlocking paper stripes. Inspired by Jack-in-the-Box, I attached the smaller box with the springy paper strips on a larger origami box – resulting a box robot with a shakey head on a springy neck

Instead of Jack-in-the-Box, how about a button in a vase?

11/16 Day 3 explorations

See Kellie's post, she spent 2 hours with JB to figure out how to animate the caterpillar, and burned through 2 batteries of 9V, JB suggested doing something else instead.

I have found several examples of how people used the nitinol wires to animate inchworm or caterpillar movements. I am listing them below. However, none of them fulfil the original goal we had to have a simple self-moving (and self-containing powersource) curve shape caterpillar. It seems to need a lot of power, so button cell battery is out, and could use external power. Not wanting to do robot legs with a lot of springs, but found the plastic one with wrapped muscle wire interesting.

Wave Form

Kellie and I played with scoring curves on paper to make terrain (e.g., rice terrace, topo map with trees?) Thin origami or thicker sketch book paper. Bonnie suggested trying wet fold.

Paper Plate

Since there is a stack of paper plates in front of me, I started exploring folding them.

Inventing Multiple Piece of Origami

I pulled out 5 pieces of papers to try to make an integrated object making use of the 2 sided colors (front side to be different shades of blue, and back side white)
