[0037] The following is a clear and complete description of the technical solution of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of this application.

[0038] According to one aspect of the present application, the present application provides a robot 100. Figure 1 The robot 100 includes a supporting part 1, a communication part 2, a power connection part 3 and a body 4.

[0039] According to an example embodiment, see Figure 1 The upper end of the support portion 1 is provided with a support frame 11. The support frame 11 may be a concave structure. The concave structure is used to carry the communication portion 2.

[0040] See also Figure 1 , the communication unit 2 includes a floating device 21 and a communication device.

[0041] The floating device 21 is supported by the support frame 11. The floating device 21 may be spherical, and the interior of the floating device 21 may be a hollow structure. Figure 2-Figure 3 , the floating device 21 can float on the water when it contacts the water.

[0042] The communication device may be provided in the floating device 21. For example, the communication device may be provided in an inner cavity of the floating device 21. The communication device transmits a communication signal to an external device (eg, an external remote controller).

[0043] For example, the communication device may be an antenna. The signal transmitted between the antenna and the external device may be a radio frequency signal. The antenna may communicate with the external device via a satellite.

[0044] For example, the antenna may transmit radio frequency signals in a frequency range of 1615.68 MHz ± 4.08 MHz, and may receive radio frequency signals in a frequency range of 2491.75 MHz ± 8.16 MHz.

[0045] join Figure 1 The power connection part 3 includes a driving device 31, a cable retracting and releasing device 32 and a connecting cable 33.

[0046] See also Figure 1 , the driving device 31 is fixed to the supporting part 1.

[0047] For example, the driving device 31 may be a motor and may be fixed to the middle portion of the support portion 1 by screws.

[0048] The cable-retracting and -unretracting device 32 can execute cable-retracting or cable-retracting under the driving of the driving device 31. The cable-retracting and -unretracting device 32 can be a cylinder.

[0049] For example, see Figure 1 One end of the motor can be fixedly connected to the central axis position of the cable retracting and unretracting device 32. The motor can drive the cable retracting and unretracting device 32 to rotate horizontally.

[0050] The connecting cable 33 is wound around the cable-retracting device 32, and one end of the connecting cable 33 is connected to the floating device 21. When the floating device 21 contacts the water, the driving device 31 can drive the cable-retracting device 32 to rotate horizontally, and the connecting cable 33 rotates with the cable-retracting device 32, realizing the cable-retracting and cable-retracting of the connecting cable 33, thereby allowing the floating device 21 to float on the water.

[0051] See also Figure 1 and Figure 4 The main body 4 includes a base plate 41, a first positioning device 42 and a walking device 43.

[0052] The lower end of the support portion 1 is fixed to the upper surface of the substrate 41. The first positioning device 42 is fixed to the upper surface of the substrate 41 to monitor and transmit a first positioning signal.

[0053] For example, the first positioning device 42 may be a Doppler Velocity Log (DVL). The first positioning signal is a positioning signal generated by the first positioning device 42. After generating the first positioning signal, the first positioning device 42 may transmit the first positioning signal to an external device in real time, or the first positioning device 42 may transmit the first positioning signal to the external device at a predetermined frequency.

[0054] See also Figure 1 and Figure 4 The walking devices 43 are disposed on opposite sides of the base plate 41. The walking devices 43 can move forward, backward, and turn, thereby enabling the robot 100 to move forward, backward, and turn.

[0055] Through the above-mentioned embodiments, the present application establishes a communication connection with an external device via a communication device, and the communication device can float on a body of water via a floating device, thereby enabling real-time communication between the communication device and the external device. The robot of the present application can avoid using an umbilical cable to transmit communication signals, and transmits communication signals based on the communication device, which is not limited by the length of the umbilical cable, thereby increasing the detection range of the robot.

[0056] The robot provided in this application has a simple structure and a simple installation and disassembly process, which facilitates subsequent maintenance work by staff.

[0057] Alternatively, see Figure 1 The body 4 may further include a second positioning device 44. The second positioning device 44 may be disposed on the upper surface of the first positioning device 42. The second positioning device 44 monitors and transmits a second positioning signal.

[0058] For example, the second positioning device 44 may be an inertial navigation system. The second positioning signal is a positioning signal generated by the second positioning device 44. After generating the second positioning signal, the second positioning device 44 may transmit the second positioning signal to the external device in real time, or the second positioning device 44 may transmit the second positioning signal to the external device at a certain frequency.

[0059] The second positioning device 44 and the first positioning device 42 can be two independent positioning devices. The two positioning devices generate two independent positioning signals, which can make the positioning of the robot 100 more accurate. Furthermore, if one positioning device fails, the other positioning device can serve as a backup, thereby improving the stability of the positioning performance of the robot 100.

[0060] Existing tracked underwater robots also transmit electrical energy through an umbilical cable. The applicant has discovered that transmitting electrical energy through an umbilical cable will also limit the detection range of the tracked robot.

[0061] Alternatively, see Figure 1 The walking device 43 includes a first walking unit 431 and a second walking unit 432. The first walking unit 431 is arranged on one side of the base plate 41, and the second walking unit 432 is arranged symmetrically with the first walking unit 431 on the other side of the base plate 41.

[0062] See also Figure 2-Figure 3 The first walking unit 431 includes a first crawler traveling structure 4311 and a first battery compartment 4312 .

[0063] The first crawler track travel mechanism 4311 includes a first crawler track 43111 and at least two first transmission wheels 43112 engaged with the first crawler track 43111. A cavity is formed between the at least two first transmission wheels 43112.

[0064] For example, see Figure 2-Figure 3 The first crawler track mechanism 4311 may include two first transmission wheels 43112. The central axes of the two first transmission wheels 43112 may be fixedly connected to the base plate 41. The first crawler track 43111 is disposed around the outer periphery of the two first transmission wheels 43112.

[0065] The surface of the first track 43111 can be provided with protrusions to increase the friction between the first track 43111 and the ground surface. The outer circumferences of the two first transmission wheels 43112 can also be provided with protrusions to allow the two first transmission wheels 43112 to mesh with the first track 43111. When the first transmission wheels 43112 rotate, they drive the first track 43111 to move accordingly. A cavity is formed between the two first transmission wheels 43112.

[0066] The first battery compartment 4312 is fixedly connected to the base plate 41. The first battery compartment 4312 is disposed in the cavity between the two first transmission wheels 43112. The first battery compartment 4312 does not contact the first track 43111 and the first transmission wheels 43112. The first battery compartment 4312 can supply power to the electric devices of the robot 100 (e.g., the drive device 31, the first positioning device 52, and the second positioning device 44).

[0067] In the present application, by setting the first battery compartment 4312 in the cavity between the two first transmission wheels 43111 , the center of gravity of the robot 100 can be lowered, so that the walking of the robot 100 is more stable.

[0068] The first crawler track travel mechanism 4311 further includes a first load-bearing wheel 43113 engaged with the first crawler track 43111. Figure 2-Figure 3The first crawler track mechanism 4311 includes two first load-bearing wheels 43113, which can be respectively disposed on either side of the first battery compartment 4312 and fixedly connected to the base plate 41. When the first crawler track 43111 is moving, the two first load-bearing wheels 43113 can prevent the first crawler track 43111 from sinking inward.

[0069] The second traveling unit 432 has the same structure as the first traveling unit 431. The second traveling unit 432 includes a second crawler traveling mechanism and a second battery compartment.

[0070] The second crawler track travel mechanism includes a second crawler track and at least two second transmission wheels meshed with the second crawler track. A cavity is formed between the at least two second transmission wheels.

[0071] For example, the second crawler track mechanism may include two second transmission wheels. The central axes of the two second transmission wheels may be fixedly connected to the base plate. The second crawler track is disposed around the outer circumference of the two second transmission wheels. The surfaces of the second crawler track may be provided with protrusions to increase friction between the second crawler track and the ground surface. The outer circumferences of the two second transmission wheels may be provided with protrusions to enable the two second transmission wheels to engage with the second crawler track. When the second transmission wheels rotate, the second crawler track moves accordingly. A cavity is formed between the two second transmission wheels.

[0072] The second battery compartment is fixedly connected to the base plate. It is located in the cavity between the two second transmission wheels. The second battery compartment does not contact the second track or the second transmission wheels. The second battery compartment can power the robot's electrical devices. The placement of the second battery compartment in the cavity between the two second transmission wheels lowers the robot's center of gravity, making its movement more stable.

[0073] The second crawler track mechanism also includes second load-bearing wheels that engage with the second crawler track. The second crawler track mechanism includes two second load-bearing wheels, which can be respectively disposed on either side of the second battery compartment and fixedly connected to the base plate 41. When the second crawler track is in motion, the two second load-bearing wheels prevent the second crawler track from sinking inward.

[0074] Through the above embodiment, the present application provides two battery compartments, thereby increasing the battery capacity and improving the balance of the robot 100. The present application uses two battery compartments to power the electric devices of the robot 100, is not limited by the length of the umbilical cable, and can increase the detection range of the robot.

[0075] The applicant of the present application has also found that when deploying a crawler-type underwater robot underwater, a crane or hoist is required to lower the crawler-type underwater robot into the water, which greatly restricts the on-site operation conditions.

[0076] Optionally, the sum of the widths of the first track 43111 and the second track is no less than half the overall width of the robot 100. This configuration increases the contact area between the two tracks and the ground surface, reducing the ground contact pressure. This allows the robot 100 to crawl on soft sandy beaches, avoiding the problem of the first track 43111 and the second track sinking. When deploying the robot 100 under water, the robot 100 can crawl from the shallow end to the underwater state on its own. This reduces the deployment requirements for the robot 100 and reduces the manpower and material costs of deploying the robot 100.

[0077] Alternatively, see Figure 5 The power connection 3 also includes a tension sensor 34. This tension sensor 34 is fixedly mounted between the cable-retracting and -release device 32 and the drive device 31. It monitors the tension in the connecting cable 33. This arrangement allows the drive device 31 (motor) to automatically drive the cable-retracting and -release device 32 to release or retract the cable based on the monitored tension. This prevents slack in the connecting cable 33 and reduces the length of the connecting cable 33 floating in the water.

[0078] Alternatively, see Figure 1 The robot 100 further includes a detection unit 5. The detection unit 5 is fixedly connected to the support unit 1, or the detection unit 5 is fixed to the upper surface of the second positioning device 44. The detection unit 5 can perform underwater detection operations for the robot. For example, the detection unit 4 can detect the underwater environment.

[0079] Optionally, the detection unit 5 may include a camera device 51 , and the detection unit 5 may further include a lighting device 52 and a detection device 53 .

[0080] The detection device 53 may be fixed at the middle position of the support portion 1 . The detection device 53 may be a sonar that can identify obstacles and assist the robot 100 in performing autonomous obstacle avoidance operations.

[0081] The camera device 51 can be fixed to one side of the upper surface of the second positioning device 44. The camera device 51 can take photos or videos during the detection operation of the robot 100. The camera device 51 can be a camera.

[0082] The lighting device 52 can be fixed to the other side of the upper surface of the second positioning device 44. The lighting device 52 can illuminate during the detection operation of the robot 100. The lighting device 52 can be a lighting lamp.

[0083] Alternatively, see Figure 4 The substrate 41 may be a base frame, which is a frame structure and can reduce the weight of the robot 100.

[0084] Optionally, the robot 100 described above may be an underwater robot or an amphibious robot.

[0085] Finally, it should be noted that the above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Although the present application is described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions of the aforementioned embodiments or replace some of the technical features therein with equivalents.
