Dr. Paul MacCready, inventor and chairman of AeroVironment Inc. holds a see-through model of Black Widow: an MAV (Micro Air Vehicle) recently developed by AeroVironment for DARPA (Defense Advanced Research Projects Agency). MacCready and his team of designers and engineers were able to accomplish the government's objective for an MAV. The Black Widow would likely serve surveillance purposes for the military, but there are other applications as well such as air quality testing and police assistance. Robo sapiens Project.
