Abstract: Aspects of the present disclosure relate generally to limiting the use of an autonomous or semi-autonomous vehicle by particular occupants based on permission data. More specifically, permission data may include destinations, routes, and/or other information that is predefined or set by a third party. The vehicle may then access the permission data in order to transport the particular occupant to the predefined destination, for example, without deviation from the predefined route. The vehicle may drop the particular occupant off at the destination and may wait until the passenger is ready to move to another predefined destination. The permission data may be used to limit the ability of the particular occupant to change the route of the vehicle completely or by some maximum deviation value. For example, the vehicle may be able to deviate from the route up to a particular distance from or along the route.

Abstract: During a vertical landing state, it is decided whether to switch from the vertical landing state to a self adjusting state. The VTOL vehicle includes the flight controller, the rotor, and a fuselage where the rotor is coupled to the fuselage via a vertical connector. If it is so decided, there is a switch from the vertical landing state to the self adjusting state. During the self adjusting state, a control signal for a rotor is generated where the control signal causes: (1) the rotor to rotate during the self adjusting state and (2) the VTOL vehicle to remain in a fixed position during the self adjusting state, in response to the control signal, and independent of docking infrastructure. During a rotors off state, a rotor off control signal is generated for the rotor that causes the rotor to turn off.

Abstract: A vertical landing is performed by an electric vertical take-off and landing (eVTOL) vehicle above a charger where the eVTOL vehicle includes a rotor that is configured to rotate during an occupant change state to keep the eVTOL vehicle stationary during the occupant change state. The eVTOL communicates with an area controller to receive an assignment of the charger from the plurality of chargers in the area based at least on part on an occupancy status of the charger. The charger is located in an area that includes a plurality of chargers. A male charging port that is part of the eVTOL vehicle and a female charging port that is part of the charger are detachably coupled and a battery in the eVTOL vehicle is charged using the charger while the male charging port and the female charging port are detachably coupled.

Abstract: A system includes a first battery in a vehicle. The vehicle is capable of being coupled at least temporarily with a second, removable battery and is powered by at least one of the first or the second battery. The system also includes a controller in the vehicle which is configured to estimate an amount of travel-related charge based at least in part on a pickup and drop off location. It is decided whether to charge the first battery using the second battery based at least in part on the amount of travel-related charge and a measured amount of stored charge in the second battery. If it is decided to do so, the first battery is charged using the second battery.

The flexible connector connects the higher unmanned multicopter and the lower unmanned multicopter. The VTM system is configured to carry a payload, including by having the higher unmanned multicopter fly above the lower unmanned multicopter with the flexible connector taut such that both the higher unmanned multicopter and the lower unmanned multicopter contribute to carrying the payload.

Abstract: A vertical takeoff and landing (VTOL) vehicle that includes a flight controller and a rotor. During a vertical landing state, during which the VTOL vehicle is performing a vertical landing, the flight controller decides whether to switch from the vertical landing state to a self adjusting state and in the event it is decided to do so, the flight controller switches from the vertical landing state to the self adjusting state. During the self adjusting state, the flight controller generates a control signal for a rotor where the control signal causes: (1) the rotor to rotate during the self adjusting state and (2) the VTOL vehicle to stay in place during the self adjusting state, such that an occupant is able to enter or exit the VTOL vehicle during the self adjusting state.

Abstract: A first propeller has a shorter blade length and a lower inertia than a second propeller. An electromagnetic field emitter is coupled to one of the first propeller or the second propeller and an electromagnetic field receptor is coupled to the other one that is not coupled to the electromagnetic field emitter. The electromagnetic field emitter emits an electromagnetic field. In response to the electromagnetic field: the electromagnetic field receptor and its coupled propeller rotate in a first rotational direction; and the electromagnetic field emitter and its coupled propeller rotate in a second and counter-rotational direction. In response to a second electromagnetic field associated with increasing torque: the first propeller increases and subsequently decreases its rotational speed; and the second propeller increases its rotational speed at a slower rate than the increase in the rotational speed of the first propeller.

Abstract: A first and a second aircraft are detachably coupled where the first aircraft is configured to perform a vertical landing using a first battery while the first aircraft is unoccupied and the unoccupied first aircraft includes the first battery. In response to detecting a second, removable battery being detachably coupled to the first aircraft, a power source for the first aircraft is switched from the first battery to the second, removable battery. After the switch, the first aircraft takes off vertically using the second, removable battery while occupied. The detachably coupled first aircraft and second aircraft are flown using the second aircraft (the power to keep the detachably coupled first aircraft and second aircraft airborne comes exclusively from the second aircraft and not the first aircraft).
