Abstract: A new area to search in a ground feature database is determined based on a last detected position. Information from a downward facing sensor coupled to an aircraft is obtained. The information from the downward facing sensor is compared with information associated with the new area in order to find a new position.

Abstract: An inner middle rotor is rotated while an inner front rotor, an inner back rotor, and an outer rotor are not rotated. The inner middle rotor is surrounded by the inner front rotor, the inner back rotor, the outer rotor, and a fuselage. After rotating the inner middle rotor while not rotating the inner front rotor, the inner back rotor, and the outer rotor, the inner middle rotor, the inner front rotor, the inner back rotor, and the outer rotor are simultaneously rotated.

Abstract: A forward velocity associated with an aircraft is received. The aircraft includes a multicopter with a plurality of rotors which rotate in a substantially horizontal plane. A pitch offset is determined based at least in part on the forward velocity, where the pitch offset changes monotonically with the forward velocity. A desired pitch is determined based at least in part on the pitch offset and a pitch angle specified via a hand control. A plurality of control signals for the plurality of rotors is determined based at least in part on the desired pitch.

Abstract: A first sensitivity level is used to interpret an input signal received from an input device in a vehicle while the vehicle is in a first region. A second sensitivity level is used to interpret the input signal received from the input device in the vehicle while the vehicle is in a second region, wherein the second sensitivity level is greater than the first sensitivity level.

Abstract: Commands, including a first and second command associated with a first and second rotor module, are determined based at least in part on a set of desired forces or moments and a plurality of health metrics, including by determining a plurality of differences between the plurality of health metrics and a threshold and assigning a lower thrust value to the first command based at least in part on the first difference and a higher thrust value to the second command based at least in part on the second difference, where the first difference indicates a higher degree of wear on the first rotor module than the second difference indicates for the second rotor module. The commands are sent to the rotor modules and after the commands are performed, updated health metrics are determined.
