Take-off apparatus and method for unmanned aerial vehicle without landing gear

A take-off apparatus for unmanned aerial vehicle without landing gear, comprising:

• an unmanned aerial vehicle, having an autopilot device for controlling a flight operation of the unmanned aerial vehicle;
• a carrier, fixed onto an auxiliary vehicle, for carrying the unmanned aerial vehicle, such that when the auxiliary vehicle is traveling in a traveling direction with respect to the earth's surface, the carrier carries the unmanned aerial vehicle to travel in the traveling direction with respect to the earth's surface;
• at least one lock/release mechanism, for locking the unmanned aerial vehicle onto the carrier in a locked state and controllably unlocking and releasing the unmanned aerial vehicle with respect to the carrier;
• a lift or airspeed sensing module configured to sense the overall lift or airspeed of the unmanned aerial vehicle carried by the auxiliary vehicle to generate a lift sensing signal or an airspeed sensing signal;
• a signal processing module configured to receive and process the lift sensing signal or the airspeed sensing signal to generate a lift value or an airspeed value, such that if the lift value or the airspeed value is greater than a predetermined threshold, then a control signal configured to drive the at least one lock/release mechanism into an unlocked state is issued, and such that the at least one lock/release mechanism unlocks and releases the unmanned aerial vehicle with respect to the carrier;
• a release motion sensing module configured to sense the at least one lock/release mechanism driven into the unlocked state to generate a release sensing signal, and the signal processing module outputting a release detach signal according to the release sensing signal, and
• a signal transmission module configured to transmit the release detach signal to the autopilot device and the autopilot device being started by the release detach signal and being controlled to perform a corresponding flight operation according to a predetermined flight program, so that the unmanned aerial vehicle can be detached from the carrier to take-off and fly according to the predetermined flight program.
