This paper presents the design and implementation
details of a complete unmanned aerial system (UAS) based
on commercialofftheshelf (COTS) components, focusing on
safety, security, search and rescue scenarios in GPSdenied
environments. In particular, The aerial platform is capable
of semiautonomously navigating through extremely lowlight,
GPSdenied indoor environments based on onboard sensors only,
including a downwardfacing optical flow camera. Besides, an
additional lowcost payload camera system is developed to stream
both infrared video and visible light video to a ground station in
realtime, for the purpose of detecting sign of life and hidden humans.
The total cost of the complete system is estimated to be 1150,
and the effectiveness of the system has been tested and validated
in practical scenarios.
