  • Method of synchronized control of electric motors of a remote-controlled rotary wing drone such as a quadricopter
    Patent number: 8725314
    Abstract: Each motor is controlled by a microcontroller and the set of microcontrollers is driven by a central controller. According to the invention, said method comprises: a preliminary step consisting at least in establishing an asynchronous serial communications link over a line between the central controller and each of the microcontrollers, and in allocating an address parameter to each microcontroller; and in operation, at least a control step proper consisting: i) for the central controller, in sending simultaneously on each link line a message containing at least one instruction specified by the address parameter of a destination microcontroller that is to execute said instruction; and ii) for each destination microcontroller, in extracting the instruction addressed thereto from said message, and executing it.
