Based on the activities of a collection of houseflies this device controls a revolver. The flies live inside an acrylic sphere with a target backdrop. As the flies move and interact inside their home they fly in front of and land on the target. These movements are collected via video. The movements are processed with custom software and output to a robotic device that aims the revolver in real-time based on the flies’ relative location on the target. When a single fly is detected the revolver simply follows the movement of that fly. If several flies are in the field of view the software moves the revolver based on the activities of the collective. If a fly is detected in the center of the target the trigger of the revolver is pulled. In this way, the flies are essentially the brain of the device controlling the revolver determining where it is aimed and when it is fired.
