Abstract: A system and method for controlling a multi-rotor aircraft that implements the unconventional use of different sized rotors. The different sized rotors than the main rotors tend to generate an unbalanced torque and pitch on the aircraft that effectively decouples the pitch and yaw control from the main rotors. The atypical design tends to lend itself to improved control capabilities and simplified control systems. Additional configurations implement the use of smaller thrust rotors that can be used to generate thrust as well as control yaw and thus counteract any remaining unbalanced torque from the odd auxiliary rotor.

Abstract: A network of high-resolution cameras for monitoring and controlling a drone within a specific operational environment such that the latency time for communication between the cameras and drone is less than that of human controlled drones. The drone can communication drone health data to the network of cameras where such information can be combined with visual image data of the drone to determine the appropriate flight path of the drone within the operational environment. The drone can then subsequently be controlled by the network of cameras by maintaining a constant visual image and flight control data of the drone as it operates within the environment.

Abstract: A collective pitch adjustment mechanism for a variable-pitch rotor that has blades for rotation about a rotor axis, e.g., for a flight vehicle or drone, via a motor. The mechanism has a servo actuator and a bearing cage for blade rotation. The servo actuator varies the collective pitch of the blades via a pushrod, and a servo actuator arm is configured for rotation and connected to the pushrod via a joint. Mounting portions are provided for securement of the blades and an actuation horn is coupled to the pushrod. The blades are rotationally and/or translationally coupled to the actuation horn via the mounting portions. The servo actuator causes rotational movement of the servo actuator arm, which in turn causes translational movement of the pushrod, which causes linear movement of the actuation horn to thereby collectively cause a collective change in a pitch angle, i.e. the collective pitch, of the blades.
