Abstract
An unmanned aerial vehicle (UAV) utilizing a command driven electronic speed controller (CD-ESC) is disclosed that incorporates methods addressing the safety and capability of electric UAVs. The disclosure describes and enables improved control and recovery of UAVs and several safety improvements for the operation of and maintenance of electric-flight UAVs. The improvements can be implemented in a fashion that allows for existing multi-rotor UAVs to be easily upgraded with the newer safety and capability features.
Claims12
A command driven electronic speed controller utilizing one active signal wire wherein the pulse width modulation of the signal is modulated in a specific and controlled, but otherwise unnatural manner to indicate a command being sent to the command driven electronic speed controller over said signal wire.
A command driven electronic speed controller utilizing one active signal wire wherein the pulse width modulation of the signal is modulated in a specific and controlled, but otherwise unnatural manner to indicate a command being sent to the command driven electronic speed controller over said signal wire during actual flight of an unmanned aerial vehicle.
A command driven electronic speed controller utilizing one active signal wire wherein the pulse width modulation of the signal is modulated in a specific and controlled, but otherwise unnatural manner to put the command driven electronic speed controller into a calibration mode in a safe manner by quickly returning to a steady state of minimum pulse widths on said signal wire.
