Implementation

The boxes were designed in CAD and printed with a laser cutter. They were each wired with one switch indicating the "on" or "off" state of the box. A red LED light on the top of the box indicates whether the box is "on" or "off". A button on the front of each box, when pushed, lets the box know when it is contact with another box. This will change the motion of the box's arms. Each box has two arms - one to flip its own switch back on, the other to flip the other box's switch off. The second arm will only be active when the button on the front of the box is pushed. 

Using a gumband, we demonstrate that when the boxes are in forced contact with each other there is a battle of survival.
