Abstract

A method and system of printable payload extensions of a quadcopter are disclosed. In one aspect, a quadcopter includes an airframe and a central portion of the airframe having at least one of an upper extender mechanism and a lower extender mechanism. The central portion enables users of the quadcopter to design payload extensions that mechanically couple with the quadcopter using a three-dimensional (3D) printing device as long as the payload extensions have a weight less than a maximum payload capacity of the quadcopter. The quadcopter couples with at a set of payload extensions including a hook assembly, an interlocking building block platform assembly, a DSLR camera assembly, a HD camera assembly, and/or a container assembly through the central portion of the airframe.

Claims

1. A quadcopter, comprising:

an airframe;

a central portion of the airframe having at least one of an upper extender mechanism and a lower extender mechanism,

wherein the central portion enables users of the quadcopter to design payload extensions that mechanically couple with the quadcopter using a three-dimensional (3D) printing device as long as the payload extensions have a weight of at least one of a weight less than a maximum payload capacity of the quadcopter and a weight equal to the maximum payload capacity of the quadcopter,

wherein a second pair of rotors folds underneath a first pair of rotors such that the first pair of rotors and the second pair of rotors are substantially parallel to each other in a folded mode of the quadcopter,

wherein the first pair of rotors further comprises of a first rotor and a second rotor physically enclosed in the airframe,

wherein an undercarriage is mechanically coupled on a lower side of the airframe,

wherein the second pair of rotors further comprises of a third rotor and a fourth rotor mechanically coupled to the undercarriage,

wherein the first pair of rotors are substantially above the second pair of rotors in the folded mode, such that the first rotor is substantially above the third rotor and the second rotor is substantially above the fourth rotor when in the folded mode,

wherein the second pair of rotors fold outward with the pivot of the undercarriage in the manner such that the second pair of rotors extend substantially perpendicularly to the first pair of rotors, such that the first rotor is substantially perpendicular to the fourth rotor and the second rotor is substantially perpendicular to the third rotor when in an extended mode,

wherein the second pair of rotors fold outward with the pivot of the undercarriage in the manner such that the second pair of rotors extend substantially perpendicularly to the first pair of rotors, such that the first rotor is substantially perpendicular to the third rotor and the second rotor is substantially perpendicular to the fourth rotor when in the extended mode,

wherein the quadcopter couples at least one of a set of payload extensions including a hook assembly, an interlocking building block platform assembly, a DSLR camera assembly, a HD camera assembly, and a container assembly through the central portion of the airframe,

wherein the second pair of rotors extend substantially perpendicularly to the first pair of rotors through a quarter turn of a central axis of the quadcopter coupling the airframe to the undercarriage, wherein the quarter turn to pivot the second set of rotors to the extended mode,

wherein the quadcopter enters a flyable condition when in the extended mode,

wherein the quadcopter automatically enables an electronic circuitry of the quadcopter when in the flyable condition, and

wherein the undercarriage wraps around the lower extender mechanism in a manner such that the lower extender mechanism is enclosed by the undercarriage.

2. The quadcopter of claim 1:

wherein the maximum payload capacity is between one and twenty pounds.

3. The quadcopter of claim 2:

wherein the central portion to encompass a cavity in which a securing means to provide for convenient insertion and ejection of a battery powering the quadcopter when a cover of the upper extender mechanism is removed.

4. The quadcopter of claim 3:

wherein the cavity to include a processor and a memory and a communication circuitry comprising at least one of a radio frequency circuitry, a wifi circuitry, and a cellular communication circuitry.

5. The quadcopter of claim 4:

wherein a pair of fan-out payload extensions span out from opposing faces of the undercarriage to provide tensile strength during a landing of the quadcopter,

wherein the airframe of the quadcopter to include a built-in camera in an encasing of at least one of the first rotor and the second rotor of the quadcopter, and

wherein the airframe to include a return home button to autonomously direct the quadcopter to a predetermined location.
