Physical Sciences Inc. (PSI), a leading developer of advanced aerospace technologies, announced the award of a contract to develop techniques and technologies that will allow next-generation MAVs to reliably operate in cluttered, harsh environments. This effort, funded through the Air Force's Office of Scientific Research (AFOSR), will focus on understanding and applying biomimetic principles observed in insects and birds to allow MAVs to recover from collisions with obstacles quickly, and undamaged.
