Abstract

An unmanned aerial delivery device has a plurality of rotors for propulsion and control, including redundant rotors in case of failure of a primary rotor, and uses a Laser Rangefinder system to guide the delivery device around an obstacle in its path until an acceptable straight-line path to a recipient is found, detect when a rotor is inoperable, and detect the distance from a take-off or landing surface to retract or extend support legs. The device has an insulated payload chamber that can only be opened by entering an unlock code on a touchscreen

Claims

1. An unmanned aerial delivery device for delivering items from a sender to a recipient, wherein the device flies to the recipient along a straight line path from the sender to the recipient, said device comprising:

a body having a payload chamber therein for containing items to be delivered to a recipient;

a plurality of rotors attached to the body around its periphery, said rotors including a number of primary rotors for normal operation of the device, and a number of redundant rotors to operate the device in the event of damage to or inoperability of one or more of the primary rotors; and

range-finder means on said device for detecting obstacles in the path of the device and guiding the device around the obstacle to maintain the straight line path to the recipient.

2. The delivery device as claimed in claim 1, wherein:

said range-finder means comprises forwardly pointing lasers on the device.

3. The delivery device as claimed in claim 2, wherein:

said rotors are supported on the ends of support arms mounted to said body; and

an annular rotor shield extends around each said rotor to protect the rotors from damage and to protect a user of the device against injury from the rotors.

4. The delivery device as claimed in claim 2, wherein:

said forwardly pointing lasers are mounted on said body and on at least two of said rotor shields.

5. The delivery device as claimed in claim 4, wherein:

a separate motor is associated with each rotor for rotating the rotor.

6. The delivery device as claimed in claim 5, wherein:

each said rotor has a laser positioned to project its beam through the plane of rotation of the rotor so that pulses are generated when the rotor is rotating properly and when a rotor is not rotating no pulses are generated, said lasers being connected with electronics on board said device to activate one or more of said redundant rotors when one or more of said rotors is not operating properly.

7. The delivery device as claimed in claim 6, wherein:

legs are on the bottom of said device to support the device on a surface.

8. The delivery device as claimed in claim 7, wherein:

at least one downwardly pointing laser is on the bottom of said device to detect the distance of the device from a landing or takeoff surface, said at least one downwardly pointing laser being connected with onboard electronics to extend said legs when the device is within about 2 meters of the surface and to retract said legs when the device is more than about 2 meters from the surface.

9. The delivery device as claimed in claim 8, wherein:

there are four legs on the bottom of the device, said legs being spaced uniformly across said bottom; and

said at least one downwardly pointing laser comprises a downwardly pointing laser associated with each leg.

10. The delivery device as claimed in claim 9, wherein:

a lockable cover is on said body in covering relationship to said payload chamber.

11. The delivery device as claimed in claim 10, wherein:

a touchscreen is on said body, and said lockable cover is unlocked by entering a code on said touchscreen.

12. The delivery device as claimed in claim 11, wherein:

a hanger is on the bottom of said body for suspending objects too large for the payload chamber.

13. The delivery device as claimed in claim 12, wherein:

a removable cover is on the bottom of said body for gaining access to internal components.

14. The delivery device as claimed in claim 13, wherein:

said payload chamber and said lockable cover are insulated.

15. The delivery device as claimed in claim 14, wherein:

an onboard battery provides power to said device.

16. The delivery device as claimed in claim 14, wherein:

said battery is rechargeable; and

a port is on said body for plugging in a charger to recharge said battery.

17. The delivery device as claimed in claim 1, wherein:

legs are on the bottom of said device to support the device on a surface.

18. The delivery device as claimed in claim 17, wherein:

at least one downwardly pointing laser is on the bottom of said device to detect the distance of the device from a landing or takeoff surface, said at least one downwardly pointing laser being connected with onboard electronics to extend said legs when the device is within about 20 meters of the surface and to retract said legs when the device is more than about 20 meters from the surface.

19. The delivery device as claimed in claim 1, wherein:

a camera is on said device to record video during flight.

20. The delivery device as claimed in claim 19, wherein:

a touchscreen is on said device on which;

the sender can write a massage to the recipient;

the sender can choose whether to send the device roundtrip or one-way;

the recipient can enter the security code to open the payload chamber;

maps and the location of the recipient are displayed;

the weather and battery charge level are displayed; and

the video recorded during flight can be displayed.
