Introduction

The geometry for this structure is based on a
6v Deresonated Tensegrity dome built by John Warren in 1982-83

George Hart and Jim Leftwich built models showing a similar weave:

    • This tensegrity structure, based on the truncated icosahedron, is built from wooden coffee stirrers and dacron thread. The closeup shows how no two sticks touch each other.

Description

Our model is made of wooden Lolly sticks and nylon thread. A large one will be built using

The model will help designing a good cover and possibly allow us to develop a (partly) removable skin.

Goatindustries have a 12.2m (40 ft) diameter geodesic for rent that can hold up to 150 people. Using the above bamboo cane we could build a structure of a up to 14m diameter (much taller than their relatively low geodesic).

Images - Day 1

Here are the first images of the model. This took me about 2.5 hours to do. Very satifsfying experience as the structure is a very simple weave made of identical parts and gets stronger as it grows.

Images - Day 2

I spent 4 hours on day 2. Its getting nice and curvy and very strong. At the bottom you can see the row of hexagons that will form the equator.
