Fitting together umbrellas, servos and origami'''

I needed to find a way of translating circular motion (of the servo) into push-pull motion to control the umbrella structure. I made little wooden attachments for the servo propeller which I thought could push directly against the bottom of the internal umbrella structure, moving it up and down regularly in different patterns. It turned out that this approach put too much force onto the servo and caused it to stop turning. Then I attached a wooden stick between the propeller and the bottom 'pushing' part of the umbrella. This worked well but didn't allow enough range of pushing, due to the size of the propeller. I solved this by putting on of my wooden propeller adaptions on, and then connecting the umbrella with this. I found that with a large oval shape a far bigger range could be achieved.
