Figure 1 illustrates a flow chart of method steps according to embodiments implementing an UAV
in fishing. A processor of the UAV controls the UAV to fly to any designated destination based on
instructions received or preset program. The designated destination may be an actual geographical
area or location determined by a manual user or a preset program. For example, the designated
destination may be an area of 10m*10m determined by GPS signal, or a specific geographical spot
reached through multiple flying instructions. In an embodiment, the designated destination is
determined before guiding the UAV with GPS navigation thereto. In an embodiment, an operator of
the UAV sends the UAV to a destination he or she prefers by providing a series of manual flying
instructions.
The positioning unit 5 adjusts the height of the sonar unit to a predetermined height by raising or
lowering the sonar unit. In an embodiment, the sonar unit is mounted on positioning unit 5. The
positioning unit 5 releases the sonar unit from the UAV before fishing and retracts the sonar unit
from water surface after fishing by using a wire. The predetermined height can be 8-10m deep
underwater. In an embodiment, the sonar unit reaches the predetermined height using feedback from
a distance sensor. In an embodiment, an operator of the UAV provides manual lifting or diving
instructions to the positioning unit 5 in real time until the sonar unit reaches the predetermined
height. Further, the sonar unit can comprise a floater which floats above water surface and a sonar
main body. The floater is connected with the sonar main body by a linking component 55
comprising a non-extendable rope or multiple connected segments of flexible rope. Assuming the
predetermined height is 8-10m deep underwater, the length of the linking component 55 can be
configured 8-10m. In an embodiment where the linking component 55 is 9m long, the sonar main
body would stay at the predetermined height of 9m underwater while the floater remains on water
surface. In an embodiment, real-time images of the floater on water surface can be provided as a
feedback. In an embodiment, a force sensor is provided between the positioning unit 5 and the sonar
unit to detect the tension on the wire which connects the sonar unit to the positioning unit 5. If the
force sensor senses the tension associated with releasing and retracting of the sonar unit is less than
a predetermined threshold, the floater is estimated to be floating on water surface and the sonar unit
is estimated to have reached the predetermined height.
The sonar unit sends multiple signals to the processor about its ambient objects. The coordinates
near the sonar unit will be determined as a fishing region if the signals are consistent with
predetermined information regarding characteristics of presence of fish. For example, potential
targets at multiple coordinates are compared in aspects such as the number and size thereof. The
coordinates where preferred results are detected are chosen as the fishing region. The fishing region
can also be determined by comparing detected results with preset values or thresholds.
After the fishing region is determined, a fishhook on the fishhook unit 3 is released to the fishing
region without a need to do so manually. This one-step approach would improve accuracy of the
deployment of the fishhook in the fishing region. Real-time images of the fishhook in water can be
provided as a feedback. It is also possible to provide a force sensor which senses the tension
between the fishhook and the fishhook unit 3. The fishhook is estimated to have been under water if
the tension between the fishhook and the fishhook unit 3 becomes less than a predetermined
threshold.
Since the sonar unit can detect potential targets in a designated destination after it reaches the
predetermined height, a favorable fishing region with the most targets can be determined by
comparing detected signals. Deploying bait in the specific fishing region can further enhance the
number and activity level of potential targets within. Thereby more efficient fishing can be
achieved.
The bait and/or fishhook can be attached to the UAV in various ways. In one embodiment, the bait
and the fishhook are hung to the launching unit 4 and the fishhook unit 3 respectively before the
UAV flies to the designated destination. Therefore, the UAV would not need to return during fishing.
The actions of launching the bait and releasing the fishhook can be performed faster. In one
embodiment, the bait is hung to the launching unit 4 before the UAV flies to the designated
destination. The fishhook is hung to the fishhook unit 3 after the UAV return from deploying of the
bait. Since there is no need to retrieve the bait, the bait can be carried by the UAV before any
detection is performed and launched as soon as the fishing region is determined. Efficiency of bait
deploying can be improved using this approach. The fish wire connecting the fishhook could get
caught on obstacles when the UAV travels to various destinations, resulting in difficulty in
retrieving the fish wire or the fishhook. To reduce the probability of such occasions, having the
UAV return to retrieve the fishhook after determining the fishing region will help. In an
embodiment, the UAV returns with the fishhook fixing to the fishhook unit 3 after the coordinates
corresponding to signals detected by the sonar unit are determined as the fishing region. Reducing
the weight of load carried by the UAV during sonar detection reduces energy cost. This will extend
the performance time of the UAV especially when a long time is spent over detecting too many
coordinates.
After the fishhook unit 3 releases the fishhook to the fishing area, the positioning unit 5 maintains
the sonar unit at the predetermined height. The sonar unit 2 performs detecting and sends the
detected signals to the processor of the UAV at a predetermined interval. That is to say, the sonar
unit 2 continuously detects its ambient objects during fishing and estimates the change of potential
targets. The estimated change of potential targets is used to determine whether a new fishing region
should be selected. Further, a series of thresholds can be prepared. For example, the UAV can move
to other coordinates near the fishing region if the detected signal falls below a certain threshold.
Upon comparing signals detected from these coordinates with the signal detected in the original
fishing region, the processor determines whether or not it is necessary to move to other coordinates.
If the detected signal falls below a minimal threshold, the processor manipulates the UAV to fly to a
new designated destination according to one of a received wireless communication and a preset
program so that a new instance of fishing can start.
The UAV also comprises a camera which sends images collected to the processor in real time. The
processor can transmit the images to a remote user using a remote controller or user terminal.
Fishing efficiency is improved by transmitting real-time images of the sonar unit and the fishhook
as a feedback. The user can also be allowed to manipulate the UAV manually based on the received
images and therefore participate in the whole fishing instance. In other words, the UAV may hover
or return according to either received wireless communication or a preset program.
As shown in Fig. 2-4, the UAV in which the above discussed method is performed comprises a
housing 1, a processor, a positioning unit 5, a sonar unit 2, a launching unit 4, a fishhook unit 3 and
a battery unit. The housing 1 comprises a top part and a bottom part. A plurality of arms are
rotatably connected to the top part of the housing 1. Each arm is equipped with a motor and an
airscrew. The processor is located within the housing 1 and is configured to control the positioning
unit 5, the sonar unit 2, the launching unit 4, the fishhook unit 3 and the flight of the UAV. The
processor is also configured to control the receiving and transmitting of wireless signals.
The positioning unit 5 and the fishhook unit 3 are arranged on the bottom part of the housing along
the line “A” which is the axis of symmetry. A via provided on the positioning unit 5 as an entrance
for any connecting components is also located on the axis of symmetry. The position on the axis of
symmetry allows the force induced by the positioning unit 5 and the fishhook unit 3 to the housing
1 to be distributed uniformly. The size of the fishhook unit 3 is designed small to facilitate
deployment of the fishhook. In other embodiments, the fishhook unit 3 is arranged on the border of
the housing 1 or an undercarriage to avoid any influence to the deployment of the fishhook. More
than one fishhook can be provided on the fishhook unit 3. More than one fishhook unit 3 can be
provided on the bottom part of housing 1.
The launching unit 4 comprises a plurality of identical single bodies. The single bodies are
distributed uniformly on the bottom part of housing 1. In some embodiments, the number of single
bodies can be 2, 4 or 8. Each single body comprises a left part and a right part separated by the axis
of symmetry “A”. The symmetric configuration improves stability of the UAV since the force
applied to the UAV by each launching unit 4 would also be symmetric. Bait for fish can be stored in
a storage component hung on the launching unit 4. The storage components are correspondingly
arranged on respective hanging areas. The positioning unit 5, sonar unit 2, launching unit 4 and the
fishhook unit 3 are arranged on the bottom part of housing 1 altogether in an effort to maintain a
balance of weight.
As shown in Fig.5 and 10, the bottom part of the housing 1 comprises a mounting groove 11 formed
by an inward depression on the outer wall. The positioning unit 5 is connected to a wire which is
also connected to the sonar unit 2. The positioning unit 5 is configured to retract and/or release the
wire. Therefore, the positioning unit 5 is mounted outside the housing 1 instead of inside. The
positioning unit 5 is detachably mounted in the mounting groove, so that it could be mounted or
removed without taking the housing 1 apart. If the wire in the positioning unit 5 get intertwined,
repair or replacement of the positioning unit 5 would become necessary. The detachable
configuration also facilitates quicker repair or replacement of the positioning unit 5. A fixing block
is provided in the mounting groove. A fixing slit is formed on the outer wall of the positioning unit
to engage with the fixing block. The detachable configuration is achieved by the fixing block and
the fixing slit. In other embodiments, the detachable configuration is achieved by elastic buckles.
As shown in Fig.6, the positioning unit 5 further comprises a rotator to engage the wire and a power
component 52 to drive the rotator. The power component 52 comprises a driving shaft on one of its
ends. The positioning unit 5 further comprises a fixing shell 51 and a back shell 53 covering the
power component 52. The rotator is arranged outside the back shell 53 and drivably connected to
the driving shaft. The fixing shell 51 and the back shell 53 form a cavity to contain the power
component 52. Assembly of the rotator, the back shell 53 and the power component 52 in such a
fashion reduces the total installing space required. A rim which engages with the end region of the
rotator extends from the side of the back shell 53 away from the driving shaft. A front shell is
connected to the back shell 53 by that rim. The back shell 53 and the front shell thus form another
cavity to contain the rotator. Placing the power component 52 and the rotator in different cavities
can avoid interference between the two. Influence to the power component 52 by the wire can also
be avoided. The front shell comprises a linking component 55 in connection with the rim and a lid
56 detachably connected to the linking component 55. Resolving the front shell into a linking
component 55 and a lid 56 facilitates repair because the rotator can be accessed by simply removing
the lid 56. Sealing rings are provided between the fixing shell and the back shell 53, as well as
between the back shell 53 and the driving shaft, to provide leakproofness.
As shown in Fig.7, the positioning unit 5 further comprises a supporting plate 57 to support the wire.
A via is opened on the supporting plate 57 to allow the wire to travel through. Displacement of the
wire results in a force applied to the supporting plate 57 which keeps the supporting plate 57 in
position. However, the tension between the supporting plate 57 and the wire would change due to
winds or inertia, leaving the wire in a loosened state. The wire could get twined with itself.
Movement of the wire can be severely influenced if this happens. In an embodiment, displacement
of the supporting plate 57 resulting from the tension between the supporting plate 57 and the wire
becoming less than a predetermined threshold would trigger the first microswitch 58. The triggering
of first microswitch 58 would send a signal to the processor. The processor then instructs the power
component 52 to stop retracting or to decelerate until the wire is tightened again. In an embodiment,
a force sensor can be arranged on the direction of the displacement of the supporting plate 57 to
detect the tension between the supporting plate 57 and the wire. The processor instructs the power
component 52 to stop retracting or to decelerate if the tension detected by the force sensor has
become less than a predetermined threshold.
The supporting plate 57 can be arranged horizontally. Since the sonar unit ascends or descends in
the vertical direction, the force induced by the wire can be applied perpendicularly to the supporting
plate 57 in order to achieve more accurate signals. The supporting plate can be a plate hinged on
one side, while the via which engages with the wire can be arranged on the other side. . In an
embodiment, the positioning unit 5 comprises a distance sensor which senses the distance between
the sonar unit 2 and the housing 1. To ensure the accuracy of the detection of distance, the distance
sensor can be provided on the housing 1 alternatively. If the distance between the sonar unit 2 and
the housing 1 falls below a predetermined threshold, the processor instructs the power component
52 to stop operation and return the sonar unit 2 from water surface back to the positioning unit 5. In
some embodiments, the distance sensor can be a second microswitch. The second microswitch is
triggered when it contacts the risen sonar unit 2. The processor instructs the power component 52 to
stop operation in response to the trigger of the second microswitch.
As shown in Fig.8 and 9, each of the launching unit 4 and the fishhook unit 5 comprises a slide bar
6 and a driving component to actuate the slide bar 6. The driving component drives the slide bar
into a displacement based on instructions received from the processor. The displacement of the slide
bar 6 causes the bait or the fishhook to be released to the fishing region. In some embodiments, the
driving component can be the power component 52. Alternatively, a first sliding groove 8 can be
provided on the bottom part of the housing 1. A pivot, which is connected to one end of the slide bar
6, is slidably connected in the first sliding groove 8. The driving component drives the pivot to slide
within the first sliding groove 8 and therefore causes the displacement of the slide bar 6. The
displacement of the slide bar 6 eventually causes the slide bar 6 to detach from the supporting
component 7. The slide bar 6 rotates about the pivot to provide space for a dropping movement of
the bait or the fishhook. The driving component comprises a linking shaft, a motor and a swing arm
fixed to a driving shaft of the motor. The two ends of the linking shaft are drivably connected to the
swing arm and the driving shaft of the motor respectively. In an embodiment, a crank link structure
is formed by the linking shaft, the motor and the swing arm. The crank link structure provides stable
functioning and allows a relatively large displacement for the slide bar 6 when space is limited.
In an embodiment, the bottom part of the housing 1 comprises a second sliding groove in which the
supporting component 7 is slidably connected. The driving component actuates the supporting
component 7 to slide within the supporting component 7. The slide bar 6 is detached from the
supporting component 7 on the movement of the supporting component 7. In other words, the slide
bar 6 is driven to rotate around its pivot by moving the supporting component 7. In comparison to
actuating the slide bar 6 alone, actuating the supporting component 7 could be performed in more
directions without considering interference of the movement direction of the slide bar 6 to its pivot.
In an embodiment, the supporting component is rotatably connected to the bottom part of the
housing 1. The driving component actuates the supporting component 7 to rotate and detach itself
from the slide bar 6. In other words, the slide bar 6 is actuated to rotate around its pivot by rotating
the supporting component 7. Rotating the supporting component instead further reduces the
occupied space needed.
As shown in Fig. 8, a baffle is disposed on the bottom part of the housing 1. A plurality of finlets are
provided on the baffle. Each finlet has a cut which engages with the slide bar 6. A through-hole is
formed by adjacent finlets and the slide bar 6. Bait can be placed within a storage component which
is fixed by the through-holes such that the launching unit 4 may launch the bait stably.
In an embodiment, the launching unit comprises a pedestal which is fixed to bottom part of the
housing 1. A first bump and a second bump are arranged on the two sides of the pedestal,
respectively. The first sliding groove 8 is arranged on the first bump. The supporting component 7 is
arranged on the second bump. The motor is fixed to the inner wall of the bottom part of the housing
1. A via for the swing arm to pass through is provided on the bottom part of the housing 1. In other
words, the first bump, the slide bar 6, the second bump and the driving component are arranged in
alignment to reduce the total occupied space. Similarly, the finlets can be provided on the pedestal.
As shown in Fig.9, the UAV may have difficulties in dragging any captured target if an obstacle
impedes the course due to external environments. For example, the fish wire may be twined around
an external obstacle when the UAV drags the fishhook to the fishing area, especially when the
length of the fish wire is relatively long. In order to secure the retrieving of the UAV, the supporting
component is designed to be slidably connected to the housing 1 along a direction perpendicular to
the slide bar 6. A round corner in contact with the slide bar 6 is provided on the supporting
component 7. An elastic component is provided between the supporting component 7 and the
housing 1. By using such a configuration, traction resistance force would be applied to the elastic
component of the supporting component 7 due to the round corner. If the traction resistance force
becomes larger than a predetermined threshold, the elastic component will be pushed to a position
in which the supporting component 7 is detached from the slide bar 6, and then the fishhook or bait
would be separated from the slide bar 6 to ensure the UAV can be retrieved. In an embodiment, a
force sensor can be provided on the supporting component 7. The force sensor detects the force
applied to the slide bar 6. If the detected force is larger than a predetermined threshold, the
processor of the UAV would instruct the driving component to separate the bait or fishhook from
the slide bar 6. Alternatively, the processor can instruct the driving component to separate the bait or
fishhook from the slide bar 6 based on the motor load of an arm of the UAV.
The supporting component 7 comprises a base fixed to the bottom part of the housing 1. An
indentation is provided in the base which engages with the slide bar 6. The first sliding groove 8
and the supporting component 7 are arranged on the side walls of the indentation. The slide bar 6 is
equipped with a fixing component to fix the fishhook. The slide bar 6 and a via provided on the
base together fasten the fixing component in place to improve stability of the fishhook on the
fishhook unit.
