Unmanned vehicle with multiple transportation modes
Systems, methods, and device include a vehicle for providing horizontal directional control in a first transportation mode and a second transportation mode. The vehicle is an unmanned aerial vehicle with the duct defining a ducted air pathway with a central axis. One or more propellor(s) are arranged to move air through the ducted air pathway. One or more flap(s) are movable between multiple positions that vary a distance between ends of the flap(s) and the central axis. The first transportation mode includes three-dimensional control by the propellor(s) and flap(s), and the second transportation mode includes two-dimensional control with the control by the propellor(s) and flap(s). The three-dimensional control includes a first flap position that corresponds to a forward direction and the two-dimensional control includes a second flap position that corresponds to the forward direction, the second flap position being an opposite position relative to the first flap position.
1. A vehicle comprising:
a duct defining a ducted air pathway with a central axis;
one or more propellers configured to move air along the ducted air pathway; and
one or more flaps disposed around the ducted air pathway and movable between a plurality of positions that vary a distance between one or more termination ends of the one or more flaps and the central axis, the one or more flaps providing horizontal directional control for the vehicle in a first transportation mode comprising a flight mode and a second transportation mode comprising a drive mode, wherein the horizontal directional control for the vehicle during the second transportation mode maintains the vehicle on a ground surface.
2. The vehicle of claim 1 , wherein:
the first transportation mode includes three-dimensional control by the one or more propellers and the one or more flaps; and
the second transportation mode includes two-dimensional control by the one or more propellers and the one or more flaps.
3. The vehicle of claim 2 , wherein the three-dimensional control includes a first flap position corresponding to a forward direction.
4. The vehicle of claim 3 , wherein the two-dimensional control includes a second flap position corresponding to the forward direction, the second flap position being an opposite position relative to the first flap position for the three-dimensional control.
5. The vehicle of claim 1 , further comprising:
one or more wheels arranged around a bottom portion of a chassis for providing at least one of horizontal ground or surface mobility in the second transportation mode.
6. The vehicle of claim 5 , wherein the duct is connected to the chassis and the one or more flaps are positioned along the bottom portion.
7. The vehicle of claim 6 , wherein the one or more flaps are a plurality of flaps that are evenly spaced apart around the chassis.
8. The vehicle of any of claim 1 , further comprising:
one or more processors; and
a storage device storing computer-readable instructions that, when executed by the one or more processors, cause the vehicle to:
move a first flap and a second flap of the one or more flaps toward the central axis to generate a first thrust at least partially along a horizontal direction;
transition between the first transportation mode and the second transportation mode; and
move a third flap and a fourth flap of the one or more flaps toward the central axis to generate a second thrust at least partially along the horizontal direction.
9. The vehicle of claim 8 , wherein the computer-readable instructions, when executed by the one or more processors, further cause the vehicle to:
retract the first flap and the second flap away from the central axis to generate the second thrust.
10. The vehicle of claim 8 , wherein generating the second thrust is responsive to determining a location of a charging station associated with the vehicle.
11. A method of controlling a vehicle, the method comprising:
positioning a first set of one or more flaps at a first flap distance relative to a central axis of a ducted air pathway of the vehicle, the first flap distance corresponding to an aerial transportation mode, such that a first thrust is generated in a first direction by the first set of one or more flaps when the vehicle is in the aerial transportation mode;
transitioning between the aerial transportation mode and a ground transportation mode; and
positioning a second set of one or more flaps at a second flap distance relative to the central axis of the ducted air pathway, the second flap distance corresponding to the ground transportation mode, such that a second thrust is generated in a second direction by the second set of one or more flaps when the vehicle is in the ground transportation mode and maintains the vehicle on a ground surface during the ground transportation mode.
12. The vehicle of claim 11 , wherein:
the first direction is a same direction as the second direction;
the first flap distance is part of a first arrangement of four flaps; and
the second flap distance is part of a second arrangement of the four flaps that is an inverted configuration relative to the first arrangement of the four flaps.
13. A vehicle comprising:
a duct defining a ducted air pathway with a central axis;
one or more propellers arranged to move air through the ducted air pathway;
a bottom chassis portion; and
one or more flaps extending from the bottom chassis portion and movable between a plurality of positions that vary an angle formed by the one or more flaps, the one or more flaps providing directional control for the vehicle in a first transportation mode comprising a flight mode and a second transportation mode comprising a drive mode, wherein the directional control for the vehicle during the second transportation mode maintains the vehicle on a ground surface.
14. The vehicle of claim 13 , wherein the one or more flaps includes four flaps diametrically opposed to each other about a center space.
15. The vehicle of claim 13 , further comprising:
one or more wheels coupled to the bottom chassis portion.
16. The vehicle of claim 15 , wherein:
the first transportation mode is an aerial mode using the one or more flaps for horizontal navigation control; and
the second transportation mode is a ground mode using the one or more flaps and the one or more wheels for the horizontal navigation control.
17. The vehicle of claim 15 , wherein the one or more wheels elevate the vehicle from the ground surface when the vehicle is in the second transportation mode, such that a gap is formed between the bottom chassis portion and the ground surface.
18. The vehicle of claim 17 , wherein:
the gap has a vertical distance; and
the one or more flaps extend downward a distance that is less than the vertical distance of the gap.
19. The vehicle of claim 13 , wherein the one or more flaps are rotatably coupled to the bottom chassis portion.
