Abstract: This paper provides the design and realization of a rotor aerial robot system.The whole system is made up of helicopter and ground control station.The communication between helicopter and ground control station are video data links and flight orders.As the principal part，the helicopter can fly autonomously and perform aerial missions.The ground control station is a man-machine conversation interface which can supervise the helicopter flight.Moreover，the vision navigation system of ground control station can lead the helicopter to land automatically.The actual flight tests show the whole system is robust and real-time，which is suit for autonomous flight，take off and landing.
