Tensegrity Structures? Robots? Icosahedrons?
Ok, let me break it down for you. First of all, you're right. They're not really robots. That was just kind of my cheap attempt to get you in the door.
They ARE tensegrity structures. Tensegrity structures? Tensional integrity a.k.a. floating compression is an architectural term that describes a structure that stays together by having each piece push or pull on another piece.
Icosahedrons are a type of polyhedron that has 20 sides.
So today we made a tensegrity structure that has 20 sides. Next time, we're going to try hooking up a motor and adding some motion in hopes of being able to call these robots... even though that's a bit of stretch, it'll still be cool.
