Flying vehicle emergency procedures

A flying device including:

• a first motor-driven rotor, said first motor-driven rotor coupled to a first sensor, said first sensor operable to sense a failure in the first motor-driven rotor;
• a first motor control circuit operable to supply power to the first motor-drive rotor under control of a processor;
• a second motor-driven rotor, said second motor-driven rotor coupled to a second sensor, said second sensor operable to sense a failure in the second motor-driven rotor;
• a second motor control circuit operable to supply power to the second motor-drive rotor under control of a processor;
• said processor coupled to a memory, the sensor, and input/output for receiving preprogrammed fault parameters;
• said memory including non-transitory program instruction operable to direct the processor to perform a method including:
• receiving a signal from the first sensor;
• comparing the signal to a predetermined value;
• determining a predetermined operational procedure in response to the comparing, and
• altering the operating characteristics of first and second motor-driven rotor,
• wherein the signal indicates a failure condition and the operational procedure effectuates mitigation of the failure condition.

A flying vehicle including:

• a first pair of electrically driven propellers, said propellers disposed on the flying vehicle on substantially opposite sides of the center of gravity;
• a second pair of electrically driven propellers, said propellers disposed substantially orthogonally to the first pair of electrically driven propellers and on substantially opposite sides of the center of gravity;
• a first set of sensors coupled to the first set of electrically driven propellers;
• a sense circuit, said sense circuit operable to receive signals from the first set of sensors, compare those signals to a predetermined value and power down the first pair of electrically driven propellers in response to the comparison.
