Ghost Robotics

Ghost Robotics is a Philadelphia-based company founded in 2015 as a University of Pennsylvania spinoff, building legged unmanned ground vehicles for defense, security, and industrial applications. Its quadruped robots include the Vision 60, used by military and security agencies for perimeter surveillance, CBRNE reconnaissance, and industrial inspection, and the Spirit 40, a smaller and more affordable variant aimed at research institutions. The company was acquired by South Korean defense firm LIG Nex1 in a $240 million deal, strengthening its position in the autonomous ground robotics market.
