The one or more components is selected from a plurality of components of different types. ## Claims ### Claim 1 A method for operating a vehicle chassis comprising: providing the vehicle chassis comprising a main body and at least one a compartment arranged on the vehicle chassis; selectively receiving a first component in the compartment, the first component being selected from a plurality of components of different types; effecting an operational state of a vehicle comprising the vehicle chassis based on a type of the first component selectively received in the compartment; inserting or retracting a second component from the plurality of components into the compartment, resulting in extending or pushing the first component within the compartment out of the compartment and effecting the operational state of the vehicle comprising the vehicle chassis based on a type of the second component received in the compartment. ### Claim 2 (depends on 1) The method of claim 1 further comprising: selecting the first component from a group comprising of a battery unit, a flight control module, and/or landing gears; wherein the vehicle is powered on and/or in motion when the vehicle is in the operational state. ### Claim 3 (depends on 1) The method of claim 1, further comprising: selecting the first component from a group comprising of a payload, a carrier configured to support the payload, and/or an arm configured to support a propulsion unit of the vehicle; wherein the vehicle is powered off and/or at rest when the vehicle is in the operational state. ### Claim 4 (depends on 1) The method of claim 1, wherein the compartment is configured to accept only one type of component within its cavity at any given time. ### Claim 5 (depends on 1) The method of claim 1, wherein the compartment is configured to accept multiple different types of components within its cavity at any given time. ### Claim 6 (depends on 1) The method of claim 1, wherein the first component includes a battery unit and the second component includes a payload and/or carrier. ### Claim 7 (depends on 1) The method of claim 1, wherein the second component is inserted or retracted in a first direction and the first component is extended or pushed out in a second direction that is same or different from the first direction. ### Claim 8 (depends on 1) The method of claim 1 wherein when the first component is pushed out of the compartment by the second component, a space is generated within the compartment for receiving a third component from the plurality of components. ### Claim 9 (depends on 1) The method of claim 1, wherein the second component is configured to push the first component out of the compartment such that the second component is completely received within the compartment. ### Claim 10 (depends on 1) The method of claim 1, wherein the second component is: a battery unit for powering the vehicle when the battery unit is inserted or retracted into the compartment; or a flight control module for flight control of the vehicle when the flight control module is inserted or retracted into the compartment. ### Claim 11 (depends on 1) The method of claim 1, wherein: the first component is a battery unit and the second component is a payload and/or carrier; and the payload and/or carrier is inserted or retracted into the compartment to push the battery unit out of the compartment such that power to the vehicle, the payload, and/or the carrier is terminated. ### Claim 12 (depends on 1) The method of claim 1, wherein: the first component is a payload and/or carrier and the second component is a battery unit; and the battery unit is inserted or retracted into the compartment to push the payload and/or carrier out of the compartment such that the battery unit powers at least one of the payload, the carrier, or the vehicle. ### Claim 13 (depends on 1) The method of claim 1, further comprising: removing or extending out the first component from the compartment based on the operational state of the vehicle. ### Claim 14 (depends on 13) The method of claim 13, further comprising: selecting the first component from a group comprising of a payload, a carrier configured to support the payload, and/or an arm configured to support a propulsion unit of the vehicle; wherein the vehicle is powered on and/or in motion when the vehicle is in the operational state. ### Claim 15 (depends on 13) The method of claim 13, further comprising: selecting the first component from a group comprising of a battery unit, a flight control module, and/or landing gears; wherein the vehicle is powered off and/or at rest when the vehicle is in the operational state. ### Claim 16 (depends on 1) The method of claim 1, wherein inserting or retracting the second component into the compartment triggers the first component to be pushed out of the compartment. ### Claim 17 (depends on 16) The method of claim 16, wherein the first component is pushed out of the compartment by a driving unit. ### Claim 18 A vehicle, comprising: a vehicle chassis including: a main body; and a compartment arranged at the main body, the compartment having at least one opening for selectively receiving one or more components a first component from a plurality of components of different types; and a propulsion system operably coupled to the vehicle chassis, the propulsion system being configured to provide lift for the vehicle; wherein: an operational state of the vehicle is effected based on a type of the first component selectively received in the compartment; and in response to inserting or retracting a second component from the plurality of components into the compartment, the first component within the compartment is extended or pushed out of the compartment, and the operational state of the vehicle is effected based on a type of the second component received in the compartment.
