Living Architecture Spring 2007 Pratt

We decided to keep experimenting with the flexinol and its output. We took an old umbrella piece and attached a flexenol wire at two of the pivit points of the umbrella arm. This movement of the arm was a lot and very fast. The only downfall was that the arm did not reract. We then also began to modify our first attempt with the flexenol and styrene tubing. Here we used heatshrink and zipties to fasten the wire more tightly with the styrene. We also came up with a track system that could guid the arm as it moved. Here are the videos of the umbrella in motion, one while its on a horizontal surface, and the other where it is in a vertical condition. The last video is showing the movement of the adjusted experiment1.
