The invention relates to an air cushion off-road robot, in particular to a full-electrical air cushion off-road robot combining an air cushion with the conventional walking mechanism and having soft land self-navigating capability. The air cushion off-road robot consists of a vehicle body, a storage battery, an inverter, a fan motor, a fan, a fan bracket, an air cushion apron, apron mounting holes, an air duct, a boosting chamber, universal wheels, a visual sensor, a GPS (Global Positioning System), a three-dimensional electronic compass, ultrasonic sensors, a data acquisition card, a vehicle-mounted computer, an anemograph, a micro air pressure sensor, a torque sensor, a rotating speed sensor, a vibration sensor, a damping spring, a suspension, driving wheels, a suspension junction and a wheel hub motor, wherein the components construct a lift system, a driving system and a measuring and controlling system respectively. The robot has a self-navigating capability, an environment identification capability and a self-controlling capability needed in soft land autonomous navigation. The air cushion off-road robot has adaptability and application robustness to various soft land conditions.
