Abstract: An unmanned aerial vehicle includes a fuselage and an arm coupled to the fuselage. The arm includes a first segment, a second segment, and a connecting assembly coupling and locking the first segment and the second segment to each other. The connecting assembly includes a first connecting member and a second connecting member. The first connecting member is rotatably coupled to one of the first segment or the second segment. The second connecting member is coupled to another one of the first segment or the second segment. The first connecting member is rotatable relative to the arm and engages with the second connecting member to lock the first segment and the second segment.

Abstract: An unmanned aerial vehicle (UAV) includes a central part, a frame assembly, and a propulsion assembly mounted to the frame assembly. The UAV also includes a servo mounted to the central part. The servo includes a driving apparatus, a control apparatus operably coupled with the driving apparatus, and a sensor configured to obtain operating parameters of the driving apparatus. The operating parameters include operating positions of the driving apparatus. The control apparatus is configured to control the driving apparatus to rotate to a predetermined position and stay at the predetermined position based on the operating positions of the driving apparatus obtained by the sensor.

Abstract: A signal line protection assembly connecting to a propulsion system of an aerial vehicle includes a foot stand and a protection sleeve. The foot stand includes a foot stand sleeve including a bearing member and a receiving portion. The bearing member has a first side and a second side that is opposite to the first side. The first side is configured to bear the propulsion system, and the receiving portion is arranged at the second side. The protection sleeve is configured to receive a signal line. At least a portion of the protection sleeve is received in the receiving portion.

Abstract: A transformable aerial vehicle includes a fuselage and a body frame. The fuselage includes a transmission mechanism including a leadscrew, at least two nuts threadedly connected to the leadscrew and connected to each other, and a nut adapter sleeved on one of the at least two nuts. The body frame includes a main support arm connected to the nut adapter, a crossbar connected to the main support arm, and a rotary power mechanism mounted on the crossbar.

Abstract: A signal line protection assembly connecting to a propulsion system of an aerial vehicle includes a foot stand and a protection sleeve. The foot stand includes a foot stand sleeve including an electronic speed controller compartment arranged below a motor of the propulsion system and forming a closed space to receive an electronic speed controller of the aerial vehicle. The protection sleeve is configured to receive a power line for the electronic speed controller. At least a portion of the protection sleeve is received in the electronic speed controller compartment.

Abstract: An aerial imaging system for transferring pictures captured from a plurality of imaging devices includes an aerial node. The aerial node has a plurality of channels for acquiring the pictures from the imaging devices and is configured to transfer the pictures.
