An unmanned aerial vehicle (UAV) includes a housing forming a central body of the UAV and including an internal compartment, one or more electrical components disposed within the internal compartment and configured to affect operation of the UAV, and an inertial measurement unit (IMU) disposed in an external compartment external to the central body. The IMU is isolated from the internal compartment such that a barometric pressure in the external compartment is independent of a barometric pressure in the internal compartment.

UAV having barometric sensor and method of isolating disposing barometric sensor within UAV

An unmanned aerial vehicle (UAV) includes a central body, a plurality of arms extending out from the central body and in fluid communication with the central body, and a plurality of propulsion units. The plurality of arms are configured to route fluid away from the central body of the UAV. Each propulsion unit attached to a corresponding arm of the plurality of arms.

Systems and methods for foldable arms

A system and kit for dissipating heat generated by a motor assembly and methods for manufacturing and using same. The motor assembly includes a housing that defines an internal chamber. The internal chamber communicates with an air inlet and an air outlet each being formed in the housing, and can at least partially receive motor inner workings. A pump assembly can be included in the internal chamber for generating an air flow during operation of the motor assembly. The pump assembly can draw air into the internal chamber via the air inlet, generating an air flow within the internal chamber. The air drawn into the internal chamber is applied to the motor inner workings, and the air heated by the motor inner workings is expelled from the internal chamber via the air outlet. Thereby, the air flow advantageously can cool the motor assembly as the air traverses the internal chamber.

System, kit, and method for dissipating heat generated by a motor assembly

An apparatus and kit for assembling a mobile platform and methods for making and using the same. When associated with a mobile platform, a power device can be installed outside a control device coupled with the mobile platform. The power device can be located outside a housing enclosing the mobile platform and exposed to an external operating environment of the mobile platform. Heat generated by the power device can be dissipated without installation of additional cooling equipment. The power device and the control device can thus have lower operating temperatures and longer lifetimes. The power device can be installed on a module associated with the mobile platform for further improving heat dissipation of the power device. The module optionally can function as a shock absorber for preventing damage to the power device in case the mobile platform is involved in a crash.

Method, apparatus, and kit for assembling a mobile platform

The invention provides systems and methods for isolating one or more sensors within an unmanned aerial vehicle (UAV). The method may comprise providing a UAV that includes a housing forming a central body of the UAV. The UAV may also include a first compartment of the central body with one or more electrical components (1) disposed therein, and (2) adapted to affect operation of the UAV. Further, the UAV may include a second compartment of the central body that is isolated from the first compartment such that the barometric pressure in the second compartment is independent of the barometric pressure in the first compartment. Additionally, the method may comprise disposing the one or more sensors within the second compartment of the UAV.

An unmanned aerial vehicle (UAV) includes a central body, a plurality of arms extending out from the central body, and a plurality of propulsion units. Each of the plurality of arms includes a stem portion, one or more branch portions, and a joint connecting the stem portion with the one or more branch portions. The joint includes a sleeve configured to lock a position of one of the one or more branch portions relative to the stem portion. Each of the propulsion units is attached to one of the one or more branch portions of one of the plurality of arms.

Systems and methods can control a pumping system. Operating characteristics of a driving apparatus are obtained. The driving apparatus is operatively coupled to a pump and operates to effect operation of the pump. Additionally, instructions are provided to an electronic speed controller. In particular, the instructions direct the electronic speed controller to control activity of the driving apparatus.

Brushless pump motor system

Systems and methods can determine a liquid flow in a spraying system. An amount of liquid that is output from the spraying system during a pump cycle is determined. A number of pump cycles that occur within a given amount of time are measured. The number of pump cycles are measured using an electronic speed controller (ESC). Additionally, the ESC indicates the number of pump cycles within a given amount of time within a threshold of precision. The amount of liquid flow in the spraying system is calculated based on the measured number of pump cycles and the determined amount of liquid that is output from the spraying system.

Spraying system having a liquid flow and rotating speed feedback

An unmanned aerial vehicle (UAV) comprises a central body, a plurality of arms that extend out from the central body, and a plurality of rotors. Each arm has one or more joints that segment the arm into a stem portion proximal to the central body and one or more branch portions distal to the central body. The one or more joints permit the one or more branch portions to move horizontally relative to the stem portion between an extended state and a compacted state. The one or more branch portions are arranged substantially parallel to a perimeter edge of the central body in the compacted state. Each rotor in the plurality is attached to the one or more branch portions.

Systems and methods are provided for transformation of a UAV from an extended state to a compacted state. The UAV can be transported in the compacted state. The UAV can comprise one or more segmented arms that can be folded to reduce the volume of the UAV. The segmented arms can be sealed to prevent ambient air, dirt, and or water vapor from entering the segmented arm. The UAV can comprise a cooling and air filtering system on-board the UAV.
