On Sept. 2nd at 10:00 in the Electrical & Computer Engineering Department, Cobleigh Hall, Conference Room 610, Christopher Casebeer will present his Electrical Engineering Master's Thesis Defense, "A System to Eavesdrop on Marmosets."
Animal behavior scientists have traditionally studied communications between a sender and a receiver. Animal communications however are hypothesized to occur in communication networks. In this project a miniaturized recording system aimed at eliciting communication network study of the common marmoset is underway. The acoustic recording collar project aims to develop a wearable recording embedded platform for a freely behaving primate. A custom embedded platform utilizing a field programmable gate array (FPGA) has been developed. A hardware descriptor language has been used to create FPGA architecture for the collar application. Sensors used and developed for this application include a global positioning system, inertial measurement unit, and microphone. These sensors provide position and accurate time information, behaviorally related motion information, and the acoustic environment of the marmoset. These senses represent the behavioral acoustic biome of the marmoset. Storage of the biome data occurs on a local micro SD flash memory card. A final printed circuit board of footprint 1.36 by 1.18 inches is complete and will be soon fitted to a 3D printed collar wearable by the marmoset. Demonstration of sensor logging to micro SD flash has been completed. Other development of the embedded system is ongoing. Fitting the wearable devices across a troop of freely behaving marmosets will allow novel communication network study in the common marmoset to occur.
