Abstract: A method and an apparatus for controlling an unmanned aerial vehicle (UAV) are provided. The UAV comprises at least one rotor. The method includes: receiving a take-off preparatory signal instructing the UAV to enter into a take-off preparatory state; controlling the at least one rotor of the UAV to rotate at a preset rotation speed in response to the take-off preparatory signal, wherein the preset rotation speed is smaller than a rotation speed that enables the UAV to hover in the air; and controlling the UAV to enter into a hovering mode under a predetermined condition, wherein the UAV is controlled to hover at a predetermined height in the hovering mode.

Abstract: A platform motor driving module includes a platform main controller, a complex driving unit, and a plurality of motor driving feedback units each including a motor driver and a driving signal feedback circuit. The driving signal feedback circuit is electrically connected to the motor driver and the platform main controller, and is configured to send a feedback signal of the motor driver to the platform main controller. The complex driving unit is individually connected to the motor drivers of the plurality of motor driving feedback units and is configured to respectively provide driving controlling signals to the motor drivers. The platform main controller is electrically connected to the complex driving unit to control the complex driving unit to generate the driving controlling signals, and electrically connected to the driving signal feedback circuits to receive the feedback signals. A platform system and a platform controlling system are also disclosed.

Abstract: A camera apparatus is disclosed. The camera apparatus comprises a first motor, a camera housing and a camera module. The camera housing is fixed directly to the motor. The camera module is located in the camera housing and capable of rotating along with the motor via the camera housing.

Abstract: A platform includes a yaw arm, a roll arm, and a pitch arm, and further includes a first, second, and third electric motors configured to drive the arms. The first, second, and third electric motors each include a first stator and a first rotor. The first stator or the first rotor is directly secured to one arm.

Abstract: A platform system includes at least one electric motor, at least one flexible cable, and a main controlling device. The main controlling device includes a controlling circuit and at least one driving circuit electrically connected to the controlling circuit. The at least one driving circuit is connected to the at least one electric motor through the at least one flexible cable.
