Construction draft 1

After I stopped researching for small helicopters, I went back to my first idea of shapeshifting. Ball-like-shaped objects are supposed to be able to change their size in all three dimensions. I want to avoid the use of pneumatics, so i’m going about a mechanical construction.

The construction is a simple wireframe model of a ball, to be covered with a soft extensible cloth. This is the first attempt for the underlying mechanics.
