  "textContent": "A take-off apparatus and method for unmanned aerial vehicle without landing gear includes an unmanned aerial vehicle, a carrier, a lock/release mechanism, a lift or airspeed sensing module, a signal processing module and a release motion sensing module. The lock/release mechanism locks the unmanned aerial vehicle onto the carrier and controllably releases the unmanned aerial vehicle from the carrier. The lift or airspeed sensing module senses an overall lift or airspeed of the unmanned aerial vehicle. When the lift or speed value of the unmanned aerial vehicle is greater than a predetermined threshold, it drives the lock/release mechanism into an unlocked state so that the unmanned aerial vehicle is released from the carrier and takes off more accurately and successfully.",
