An unmanned aerial vehicle includes a blade that is configured to rotate relative to a body of the unmanned aerial vehicle to enable the unmanned aerial vehicle to fly. The blade defines at least one cavity. The blade includes a power source and an auxiliary rotor configured to use the power source to rotate relative to the blade to cause the blade to fly. The auxiliary rotor is configured to withdraw into the at least one cavity. The blade is configured to decouple from the unmanned aerial vehicle. The auxiliary rotor is configured to extend from the at least one cavity and cause the blade to fly such that the blade navigates away from the unmanned aerial vehicle using the auxiliary rotor.
