## Abstract

The present disclosure is directed toward systems and methods for swapping a battery assembly between an unmanned aerial vehicle (UAV) and an unmanned aerial vehicle ground station (UAVGS). In particular, systems and methods described herein enable a battery swapping assembly to remove a battery assembly from within the UAV and store the battery assembly within a plurality of battery banks that are linearly arranged within the UAVGS. For example, the battery arm can move along an axis of movement relative to the battery banks to conveniently transfer one or more battery assemblies between the UAV and the battery banks within the UAVGS.

## Claims

### Claim 1

A system comprising:
an unmanned aerial vehicle (UAV) comprising:
a main body; and
a battery assembly within the main body of the UAV; and
an unmanned aerial vehicle ground station (UAVGS) comprising:
a landing housing sized and configured to receive the UAV when the UAV lands within the UAVGS; and
a battery swapping assembly comprising:
a battery arm operable to extend through the landing housing to engage the battery assembly and remove the battery assembly from within the UAV;
a plurality of battery banks linearly arranged within the UAVGS and sized to receive the battery assembly; and
an alignment assembly, the alignment assembly comprising an actuator that causes the battery arm to move along a first axis and align with respect to the plurality of linearly arranged battery banks to allow the battery arm to insert the battery assembly within the plurality of linearly arranged battery banks.

### Claim 2 (depends on 1)

The system as recited in claim 1, wherein the plurality of battery banks comprises one or more charging contacts corresponding to one or more battery contacts on an end of the battery assembly, wherein the one or more charging contacts are positioned so as to couple to the one or more battery contacts when the battery assembly is inserted within the plurality of battery banks.

### Claim 3 (depends on 2)

The system as recited in claim 2, wherein the charging contacts provide a charging signal that charges the battery assembly when the battery assembly is inserted within the plurality of battery banks.

### Claim 4 (depends on 1)

The system as recited in claim 1, wherein the plurality of battery banks comprise a latch that secures the battery assembly within the plurality of battery banks when the battery assembly is inserted within the plurality of battery banks.

### Claim 5 (depends on 4)

The system as recited in claim 4, wherein the battery arm comprises a latch engagement assembly sized to engage the latch and allow the battery arm to unlock the battery assembly from within the plurality of battery banks.

### Claim 6 (depends on 1)

The system as recited in claim 1, wherein the battery arm comprises one or more proximity sensors that detects a distance between an end of the battery arm and the battery assembly when the battery assembly is within the plurality of battery banks.

### Claim 7 (depends on 1)

The system as recited in claim 1, wherein the landing housing comprises an opening having a position along the first axis with respect to the plurality of linearly arranged battery banks.

### Claim 8

A battery swapping assembly, comprising:
a battery arm operable to extend into an unmanned aerial vehicle ground station (UAVGS) to grip a battery assembly within an unmanned aerial vehicle (UAV) and retract the battery assembly from the UAV while gripping the battery assembly;
a plurality of battery banks linearly arranged within the UAVGS, the battery banks sized to receive the battery assembly; and
an alignment assembly coupled to the battery arm, the alignment assembly comprising an actuator that causes the battery arm to move along a first axis and align a first end of the battery arm with respect to the plurality of linearly arranged battery banks to allow the battery arm to insert the battery assembly within the plurality of linearly arranged battery banks

### Claim 9 (depends on 8)

The battery swapping assembly as recited in claim 8, wherein the first axis is a rotational axis.

### Claim 10 (depends on 9)

The battery swapping assembly as recited in claim 9, wherein the actuator causes the battery arm to rotate with respect to the actuator along the rotational axis.

### Claim 11 (depends on 9)

The battery swapping assembly as recited in claim 9, wherein the first axis is a linear axis.

### Claim 12 (depends on 11)

The battery swapping assembly as recited in claim 11, wherein the actuator causes the battery arm to move linearly with respect to the actuator along the linear axis.

### Claim 13 (depends on 9)

### Claim 18

A method comprising:
removing a battery assembly from within an unmanned aerial vehicle (UAV) by causing a battery arm to grip a first end of the battery assembly and retract from the UAV;
aligning the battery arm with an opening of a first battery bank of a plurality of battery banks that are linearly arranged within an unmanned aerial vehicle ground station (UAVGS) by causing the battery arm to move along an axis of movement within the UAVGS; and
