[0002] After a natural disaster, the disaster area often faces complex terrain conditions, including but not limited to mud, sand, gravel roads, and grasslands. These unique terrains not only increase the difficulty of rescue operations but may also pose challenges to traditional rescue equipment.

[0003] Traditional search and rescue robots typically employ a single mode of locomotion (such as wheeled or tracked vehicles), which can have limitations when facing different terrains. For example, wheeled robots are prone to getting stuck on soft ground, while tracked robots are less efficient on hard surfaces. Search and rescue robots with a single mode of locomotion struggle to operate efficiently in complex and varied terrains, especially on soft or uneven ground, where they are prone to getting stuck or overturning, thus limiting the search and rescue range and efficiency.

[0004] To address these issues, we provide a search and rescue robot adaptable to various terrains. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1, please refer to Figure 1-4 This utility model is a search and rescue robot adaptable to various terrains, including a robot body 100, and a track assembly 300 and a roller assembly 400 for the robot body 100 to move.

[0034] The robot body 100 includes a frame 101 at the bottom, a power compartment 102 fixed to the upper part of the frame 101, an equipment compartment 103 fixed to the upper part of the power compartment 102, a baffle 104 fixed to the bottom side of the power compartment 102, and a storage box 105 fixed to the upper side of the baffle 104.

[0035] The track assembly 300 includes a track body 301, and a drive wheel 303 and an auxiliary wheel 302 that are fitted inside the track body 301; the roller assembly 400 includes a transmission disc 401, a mounting disc 403 that is fixedly connected to the transmission disc 401 via a support arm 402, and a wheel 404 mounted inside the mounting disc 403; by using two different modes of movement, namely tracks and rollers, the search and rescue robot can move freely in a variety of complex terrains, including mud, sand, gravel roads, and grasslands.

[0036] Specifically, a bracket 101a is fixed inside the frame 101. A switching assembly 500 is installed on the bracket 101a. The switching assembly 500 includes a transmission rod 501 disposed at the end of the frame 101, a worm gear fixed at the middle position of the transmission rod 501, a worm 502 cooperating with the worm gear, and a motor 503 for driving the rotation of the worm 502. The motor 503 is fixed inside the bracket 101a.

[0037] The transmission rod 501 passes through the center of the drive wheel 303 and the auxiliary wheel 302 located on the side, and the end of the transmission rod 501 is fixed to the transmission disk 401. The transmission disk 401 is fitted to the outside of the drive wheel 303 and the auxiliary wheel 302 located on the side. A micro motor is equipped on the outside of the mounting disk 403, and the output end of the micro motor cooperates with the wheel 404.

[0038] Furthermore, a drive motor 304 is installed inside the bracket 101a, and the drive motor 304 is engaged with the drive wheel 303 via a transmission gear.

[0039] Furthermore, the power supply compartment 102 has a built-in rechargeable power supply, and searchlights 102a are embedded at both ends of the power supply compartment 102. The power supply compartment 102 has a built-in high-performance lithium battery pack, supporting long-term battery life. The searchlights 102a at both ends use LED light sources, which are bright and energy-efficient, and can provide good lighting in a variety of harsh conditions. The equipment compartment 103 has a display screen 103a at the front end and a speaker 103b at the rear end. The equipment compartment 103 contains electronic devices such as a central processing unit, memory, and wireless communication module. The display screen 103a at the front end can display the robot's status information and environmental parameters in real time, and the speaker 103b at the rear end supports two-way voice communication, which is convenient for remote command. The storage box 105 has a transparent observation window on the side and a lid on the top. The storage box 105 is convenient for loading and unloading rescue supplies, the transparent observation window allows for quick inspection of the contents, and the lid is waterproof and dustproof to ensure the safety of the contents.

[0040] The operation process in this embodiment is as follows:

[0041] 1. Determine whether to switch the travel mode based on the current terrain conditions. For example, switch to track mode on soft sand and use wheel mode on hard, flat ground.

[0042] 2. Send a switching command through the remote control interface, observe whether the switching process is smooth, and confirm that the new travel mode has been correctly activated.

[0043] 3. During the mode switching process, the switching component 500, based on the self-locking and transmission characteristics of the worm gear and worm 502, transmits torque to the worm 502 when the motor 503 starts. When the worm 502 rotates, it drives the worm gear and transmission rod 501 to rotate synchronously, thereby changing the positional relationship between the track assembly 300 and the roller assembly 400 and completing the mode switching. When the motor 503 is not started, the worm gear is locked by the worm 502, which keeps the transmission rod 501 relatively fixed, thereby ensuring that the roller assembly 400 maintains a relatively fixed position and does not affect the operation of the track assembly 300.

[0044] IV. When the track assembly 300 is working, the drive motor 304 provides power output, which drives the track body 301 through the drive wheel 303. Its auxiliary wheel 302 is used for the stable operation of the track body 301. When the roller assembly 400 is in the initial position, it is located diagonally above the track assembly 300. At this time, the roller assembly 400 is not working. When the roller assembly 400 switches to below the track assembly 300, it lifts the robot body 100 and drives the rotation of the wheel 404 under the action of the micro motor, thus completing the switching of the travel mode.

[0045] Example 2, please refer to Figure 1 and Figure 2Based on the first specific embodiment, a search and rescue robot adaptable to various terrains also includes a search and rescue detection component 200 mounted on the upper part of the robot body 100. The search and rescue detection component 200 includes a rotating platform 201 fixed to the middle position of the upper side of the equipment compartment 103, and a gimbal 202 fixed to the rotating end of the rotating platform 201. The rotating platform 201 can rotate freely 360 degrees, improving the flexibility of the gimbal 202. The image information and sensor data collected by the gimbal 202 are transmitted to the central processing unit in the equipment compartment 103 for processing. The processed information is then sent back to the command center or the operator's terminal device through the wireless communication module, realizing real-time monitoring and data analysis of the search and rescue site.

[0046] Specifically, a visual camera 202a is provided on the upper periphery of the gimbal 202, and a sensor module 202b is integrated on the lower periphery of the gimbal 202. The visual camera 202a has night vision capabilities and can clearly image under low light conditions. The sensor module 202b integrates various types of sensors, such as infrared sensors, sound sensors, and gas detectors, for detecting signs of life and environmental conditions. The connection principle between the visual camera 202a and the sensor module 202b is not further described here.

[0047] The operation process in this embodiment is as follows:

[0048] 1. Place the robot in the designated position, connect the power supply, wait for the system to complete the self-test, connect to the robot via the remote control or the application on the mobile device, confirm that the connection is good, and check the status of all sensors and cameras on the control interface to ensure that they are all working.

[0049] 2. Turn on the vision camera 202a and sensor module 202b to start scanning the surrounding environment.
