+FABRICATION_DESIGN DEVELOPMENT
Option 1: The second modification we made to our initial prototype was the use of tensioning cables to greater capture the movement of crawling into a ball. By placing cables at the point of each vertex and attaching them to a common point, the movement could create a greater force upon the prototype and stretch the spikes further, to establish a greater boundary. Problem: To accomplish this we initially used copper wire, however this proved to be too rigid and did not adequately fit the body. The use of this material therefore did not accentuate the effect of the movement, but rather diminished it since it did not tightly hug the body.
Option 2: As a second option, we used a more flexible material: string. This proved to hug the body much more closely and achieved the intended effect of exaggerating the effect of the movement.
