US Patent 9944213 Robotic cargo system

A robotic cargo system provides an ability to move cargo without requiring the use of additional material handling equipment such as forklifts and K-loaders. The robotic cargo system may operate as a vehicle during drive maneuvering, and may operate to lockdown on an aircraft as a pallet during flight. The system may navigate over rough terrain while carrying heavy loads through the use of a track-based propulsion system. The system may provide a cargo loading system, ramp ascent and descent algorithms, and autonomous navigation.
