Two symmetrically arranged cavitation lifting mechanisms are provided below the cavitation component support 410.

[0030] In this application, the cavitation pressing component 400 consists of a trenching lifting device and a cavitation pressing mechanism. The trenching lifting device consists of a lifting sleeve 411, a lifting bearing end cover 412, a lifting crank 413, a pressing spring 414, a lifting inner cylinder 415, a connecting round tube 416, a connecting piece 417, a support plate 418, a fixed pin 419, and a rotating pin 420.

When the pressing hole mechanism descends to contact the ground, the lifting mechanism continues to descend and the pressing spring 414 is compressed, firmly pressing the pressing hole component 400 onto the ground. The transplanter moves forward and the cylinder with angle steel 427 rotates accordingly, thereby pressing out evenly spaced seedling holes on the ground.

[0031] In one embodiment, a binocular camera 224 is installed on the seedling tray 223 and connected to the controller 225. Incremental rotary encoders 148 are installed at the output shafts 146 of the two gearboxes 143 and at the roller motor 213 and are electrically connected to the controller 225. A 16-line lidar is installed on the roof of the machine and electrically connected to the controller, and an 8-line lidar is installed on the side of the machine and electrically connected to the controller. This facilitates the detection and control of the equipment.

[0032] In one embodiment, to achieve automatic operation of the device, this application provides a control method such as... Figure 5 and Figure 6 As shown. Importantly, this application achieves real-time plant spacing adjustment during transplanting by adjusting the ratio of the track motor speed to the drum motor speed; and achieves fully automated transplanting by using a laser radar combined with an encoder and controller.

[0033] In this application, the overall process of the transplanter operation is as follows: First, the system sets the plant spacing. Then, the multi-arm cooperative seedling delivery component 300 begins loading seedlings. Sensors on the transplanting component 200 monitor whether the seedlings on the conveyor belt surface are fully loaded. If the main controller determines that the loading is not complete, loading continues. If the main controller determines that the loading is complete, the transplanter begins operation, and the walking motor and seedling delivery motor start running. The main controller uses the pulse count fed back by the incremental rotary encoder 148 to determine whether the ratio K of the transplanting speed to the walking speed is equal to the set value. If the main controller determines that the loading is not complete, the ratio of the transplanting speed to the walking speed is adjusted to be equal to the set value. If the main controller determines that the loading is complete, operation continues. The main controller uses real-time 3D scene information transmitted by the LiDAR to determine whether the transplanter's travel path has deviated or encountered obstacles. If the main controller determines that the loading is complete, it uses the real-time 3D scene information transmitted by the LiDAR to issue path correction instructions to avoid obstacles. If the main controller determines that the loading is not complete, operation continues. Once the seedlings on the conveyor belt surface have been transplanted, one transplanting cycle is complete. Then, the seedling filling operation is repeated to start the next transplanting cycle.

[0034] like Figure 6 As shown, the overall process of LiDAR path planning consists of the following steps: The first step is LiDAR environmental perception. A 16-line LiDAR on the roof (120° forward field of view, 20m detection range) and an 8-line LiDAR on the side of the fuselage (scanning furrows downwards) actively emit laser beams and receive reflected signals, generating a high-precision 3D point cloud using the time-of-flight principle. This is used to characterize the raw spatial data of the surrounding environment (ridges, crops, obstacles).

[0035] The second step is data processing and feature extraction. The original 3D point cloud is input, and statistical filtering is used to remove noise points caused by weeds, etc. The RANSAC algorithm is then used to separate the point cloud into "ground points" (ridge surface, field ridges) and "non-ground points" (crops, stones). Finally, feature extraction is performed to fit the ridge centerline (as a reference for the global path) and the furrow edge line (to determine the safe driving boundary of the transplanter and prevent the furrow from collapsing).

[0036] The third step is path planning layering, which consists of two parallel and collaborative parts: global path planning and local path planning. In global path planning, a "reciprocating" approach is used, with a fixed line spacing of 90cm and a turning radius of no less than 3m to avoid crushing seedlings, outputting an ideal, barrier-free global reference path. In local path planning, the trigger condition is the detection of static obstacles (such as stones) with a diameter >10cm by LiDAR, using A... The algorithm replans in real time, generating obstacle avoidance paths (bypassing from the left or right) and ensuring a safe distance of ≥30cm from obstacles. The seedling transplanting action is paused during obstacle avoidance.

[0037] The fourth step is path execution and control, which uses the model predictive control (MPC) algorithm as the control core. Based on the dynamic model of the transplanter, MPC predicts the motion state in the future, calculates the optimal steering and speed control commands through rolling optimization, and sends them to the actuator (motor).

[0038] The fifth step, multi-sensor feedback, is a crucial closed-loop correction step used to ensure accuracy during long-term operation. The IMU (Inertial Measurement Unit) can detect the transplanter's own attitude (such as tilt and steering angular velocity) in real time, compensating for LiDAR point cloud jitter and positioning drift caused by road bumps. The incremental rotary encoder 148 can accurately measure the actual number of rotations of the drive shaft, providing accurate travel distance and speed feedback, which is fused with LiDAR positioning information to correct accumulated errors. This flowchart and description fully demonstrate how LiDAR acts as the "eyes," combined with the IMU and encoder (the "cerebellum" responsible for balance and proprioception), and under the command of the MPC (Multi-sensor Control Center), drives the transplanter, an intelligent device, to achieve high-precision, autonomous path planning and operation tasks in complex fields.

[0039] In one embodiment, to address the pain points of existing transplanters, such as heavy reliance on manual seedling separation and driving, inability to adapt to scattered plots, inability to adjust plant spacing in real time, and easy deviation of the working path leading to low transplanting qualification rate, an intelligent electric transplanter is designed that can adaptively adjust plant spacing, drive automatically, and automatically separate seedlings, thereby realizing unmanned operation in the field, with the machine itself completing automatic driving, seedling placement, and transplanting.

[0040] To achieve the above objectives, this invention provides an intelligent fully automatic transplanter for rhizomes and other medicinal herbs. The intelligent fully automatic transplanter for rhizomes and other medicinal herbs comprises an electric tracked chassis 100, a transplanting component 200, a multi-arm cooperative seedling delivery component 300, a planting hole component 400, and a chassis frame. The electric tracked chassis 100 includes a chassis support 110 and connected, symmetrically arranged left and right track assemblies 130 and a chassis power unit 140. The chassis support 110 is connected to the track assemblies at its lower part, and has lifting devices for the transplanting component 200 and guide tubes for the transplanting component 200 support arranged on both sides at its upper part, with two battery boxes 113 arranged in the middle. The track assembly consists of side supports 121, support rollers 122, guide rollers 123, trailing rollers 127, power wheels 126, and rubber tracks 128. The chassis power unit 140 consists of a sprocket and chain 141, a gearbox 143, a DC brushless motor 144, and a chain protection cover 145. The gearbox 143 and the motor are symmetrically arranged above the left and right track assemblies 130 and are mounted on the chassis frame via a gearbox 143 mounting plate. Power is output from the DC brushless motor 144, then through the gearbox 143, and finally through the gearbox output shaft 146, and finally transmitted to the drive wheel 126 via chain drive to provide power for the entire chassis.

[0041] The upper part of the transplanter described in this application is a transplanting component 200, which consists of a transplanting component support 210, a transplanting component side plate 211, a partition-type conveyor belt 212, a roller motor 213, a driven roller shaft 214, a reinforcing support tube 215, a belt tensioning device 216, an upper surface seedling blocking groove 217, a front surface seedling blocking groove 218, a front surface hollow seedling blocking groove 219, a front side fixing plate 220, a rear side fixing plate 221, a lower end fixing plate 222, a seedling tray 223, a transplanting component lifting device, a controller 225, and a touch screen human-machine interface 226. The transplanting component support is installed in the transplanting component support guide tube 112 on the chassis support 110. The upper end of the transplanting component support guide tube 112 is provided with a set screw to prevent the actuators above the transplanter chassis from shaking due to the unstable center of gravity of the transplanting component 200. The lower end of the seedling transplanting component lifting device is mounted on the chassis bracket 110, and the upper end is mounted on the seedling transplanting component bracket. The seedling transplanting component 200 and the multi-arm coordinated seedling delivery component 300 can be simultaneously raised and lowered by shaking the rocker arm. It is particularly important to note that during raising and lowering, the lifting mechanisms at both ends must move upwards to approximately the same height simultaneously to prevent the seedling transplanting component bracket from getting stuck in the guide tube 112. The seedling transplanting component side plate 211 is mounted on the seedling transplanting component bracket. The partition-type conveyor belt is installed between the two seedling transplanting components 200 via a roller motor 213, two driven roller shafts 214, and four reinforcing support tubes 215. The roller motor 213 and the two driven roller shafts 214 are mounted on the seedling transplanting component side plate 211 via roller mounting bearings, and the four reinforcing support tubes 215 are fixed to the seedling transplanting component side plate 211 with bolts. The partition is an independent divider on the conveyor belt. The upper and front surfaces of the partition-type conveyor belt 212 of the transplanting component 200 are provided with seedling-blocking grooves to prevent root and rhizome Chinese medicinal materials from moving left and right during transplanting. The upper surface seedling-blocking groove 217 is installed between the front fixing plate 220 and the rear fixing plate 221 of the transplanting component. The front surface seedling-blocking groove 218 is installed between the front fixing plate 222 and the lower fixing plate 222 of the transplanting component. Their function is to prevent the seedlings from moving left and right during the movement of the conveyor belt. The front surface hollow seedling-blocking groove 219 is installed between the front fixing plate 222 and the lower fixing plate 222 of the transplanting component. Its function is to prevent the seedlings from falling off the partition during the vertical downward movement of the conveyor belt. On the other hand, the hollow groove structure makes it easy to observe the transportation of the seedlings on the conveyor belt. There is a seedling box at the front and a seedling box at the back of the transplanting component, which are respectively fixed to the front fixing plate 22 and the rear fixing plate 221 of the transplanting component.After the multi-arm cooperative seedling delivery component 300 takes the seedling from the seedling box, it is placed in the partition of the partition-type conveyor belt 212. The power is provided by the rolling motor, which drives the belt to rotate. The seedling moves forward with the conveyor belt. The seedling first moves horizontally and then changes to vertical downward. During the movement, the upper surface seedling blocking groove 217, the front surface seedling blocking groove 218, and the front surface hollow seedling blocking groove 219 can ensure that the seedling is always within the partition, thus ensuring the accuracy of transplanting. Finally, the seedling is placed into the seedling hole pressed by the pressing component 400 at the end of the conveyor belt, thus completing the entire transplanting process.

[0042] The entire transplanting process of the equipment is intermittent. That is, when the upper surface of the transplanting component 200 is filled with seeds, the transplanter starts working. After the seedlings are transplanted, the transplanter stops working and waits for filling. Then, the filling-working-filling process is repeated. The advantage of this intermittent process is that the conveyor belt is stationary during the seed delivery process. That is, the relative position of the conveyor belt compartment and the robotic arm is fixed. The robotic arm does not need to dynamically track the position of the compartment in real time to place the seedlings into the compartment. At the same time, the working efficiency of the intermittent process is not much lower than that of the continuous process. In the continuous process, although the conveyor belt speed can be adjusted to be very fast, the seed delivery speed of the robotic arm is limited, which greatly limits the upper limit of the conveyor belt speed. In contrast, although there is no working during the seed delivery process in the intermittent operation mode, there is no upper limit to the conveyor belt speed after the seed delivery is completed. As long as the walking speed and the conveying speed are matched, the stability of the transplanting spacing can be guaranteed. The time wasted by the transplanter stopping to wait for filling is compensated for here.

[0043] The seedling box is equipped with a binocular camera 224, which can provide the robotic arm with the position information of the seedling inside the seedling box. By establishing a coordinate system with the mechanical origin of the robotic arm as the origin, the position information fed back by the binocular camera 224 can be used to determine the coordinates of the seedling relative to the robotic arm, thereby achieving precise positioning of the seedling and enabling the robotic arm to accurately pick up the seedling during the seedling grabbing process. After the robotic arm retrieves the seedling, it returns to its origin and places the seedling into the corresponding conveyor belt compartment. Since the relative coordinates of the robotic arm's origin with respect to each conveyor belt compartment remain constant (i.e., the coordinates of each compartment are fixed), there's no need to use binocular cameras (e.g., 224) to measure position information. Specifically, the robotic arm's origin is coordinate A, the seedling's position is coordinate B, and the conveyor belt compartment's position is coordinate C. The entire seedling transfer process involves the binocular camera (e.g., 224) feeding back the position information at coordinate B to the robotic arm. The robotic arm then moves from coordinate A to coordinate B, retrieves the seedling at coordinate B, and returns to coordinate A. Because the relative position of A and C remains constant, coordinate C remains constant as well. Finally, the robotic arm carries the seedling from coordinate A to coordinate C and places it into the conveyor belt compartment, thus completing one seedling transfer cycle. The upper surface of the seedling transplanting component 200 is divided into four areas. Each robotic arm is responsible for delivering seedlings to its corresponding area. During operation, each robotic arm repeatedly takes seedlings from the seedling box and places them into the conveyor belt compartment. In this process, each robotic arm needs to cooperate to ensure the accuracy and efficiency of seedling delivery, and to prevent accidents caused by the robotic arms colliding with each other during operation.

[0044] The cavitation pressing component 400 consists of a trenching lifting device and a cavitation pressing mechanism. The trenching lifting device consists of a lifting sleeve 411, a lifting bearing end cover 412, a lifting crank 413, a pressing spring 414, a lifting inner cylinder 415, a lead screw device, a connecting round tube 416, a connecting piece 417, a support plate 418, a fixed pin 419, and a rotating pin. The cavitation pressing mechanism consists of a trenching shaft, a jacking pipe, a bearing chamber 423, an inner small round tube 424, an end cover 425, an outer large round tube 426, an angle steel 427, and a cavitation pressing component bracket 410. The hole-pressing component bracket 410 is installed at the front end of the chassis bracket 110. When the lifting handle 413 is cranked, the screw device inside the trenching lifting device rotates accordingly, thereby realizing the lifting of the entire hole-pressing mechanism. When the hole-pressing mechanism descends to contact the ground, the lifting mechanism continues to descend and the pressing spring 414 is compressed, firmly pressing the hole-pressing component 400 onto the ground. The transplanter moves forward and the cylinder with angle steel 427 rotates accordingly, thereby pressing out evenly spaced seedling holes on the ground.

[0045] This application involves installing incremental rotary encoders 148 for speed measurement in three parts of the machine. These three parts are the output shafts 146 of the two gearboxes 143 and the drum motor 213. The main function of the encoders at the output shafts 146 of the two gearboxes 143 is to measure the actual rotational speed of the output shafts 146 of the gearboxes 143, which is obtained according to the following formula. and in, : Linear velocity of the left track; Linear velocity of the right track; and All are correction factors; Circumference of the pitch circle of the drive gear; : Sprocket transmission ratio; The rotational speed measured by the encoder on the left side; The rotational speed measured by the encoder on the right; The rotational speed of the drive gear is calculated using the reduction ratio of the sprocket, thus determining the travel speed of the left and right tracks. During this calculation, due to the influence of transmission efficiency and the inconsistency of the pulses fed back from the encoders on both sides, different correction coefficients K1 and K2 are introduced (the correction coefficients differ for different track gears; here, only the operating speed is corrected to ensure accuracy). The track travel speed calculated using these correction coefficients, compared to the data obtained from the encoders, is highly similar to the actual track travel speed. Simultaneously, accurate measurement of the left and right track travel speeds provides a practical basis for differential steering. When the left track travel speed is greater than the right track travel speed and the direction is the same, the transplanter turns right; when the left track travel speed is less than the right track travel speed and the direction is the same, the transplanter turns left; when the left and right track speeds are equal in magnitude but opposite in direction, a turn on the spot is achieved. The encoder at roller motor 213 primarily measures the actual rotational speed of roller motor 213 and calculates the linear speed of the belt using a formula. in, Linear speed of the conveyor belt; Correction factor; : Drum motor diameter; The rotational speed of the drum motor as measured by the encoder; Similarly, a correction factor is introduced here. This is because belt slippage is unavoidable during belt conveyor operation.

[0046] To adjust the seedling spacing, the transplanting speed and the walking speed must be matched. The transplanting speed refers to the number of seedlings transplanted per unit time, while the walking speed refers to the displacement of the transplanter per unit time. The ratio K of the walking speed to the seedling spacing determines the seedling spacing. A larger K value results in a larger seedling spacing, and a smaller K value results in a smaller seedling spacing. The K value is only related to the structural parameters of the transplanter itself and the system-set seedling spacing. Once the structural parameters and the set seedling spacing are determined, the K value is constant. By using a fuzzy PID control algorithm to keep the ratio K of the seedling spacing and walking speed relatively stable, the actual seedling spacing is highly consistent with the set seedling spacing.

[0047] During the movement, when the transplanter moves forward... There is a direct proportional relationship between transplanting speed and walking speed, that is... and There exists a direct proportional relationship between them and it is a constant. ( The rotational speed measured by the left encoder. The speed of the drum motor measured by the encoder. Correction factor Plant spacing, Spacing between partitions Circumference of the pitch circle of the drive gear (Sprocket transmission ratio) The structural parameters of the transplanter, once confirmed, will not change. As long as a suitable plant spacing is set, the K value will also be constant. Therefore, the main controller only needs to control... and The ratio corresponding to the K value ensures that the plant spacing is the set value, and this can be adjusted in real time. and This ratio allows for real-time adjustment of plant spacing during transplanting.

[0048] The multi-arm collaborative transplanting system of the robotic arm is designed for Panax notoginseng seedlings that are randomly piled up in boxes, containing only root substrate and no stems or leaves. The transplanter is equipped with a binocular camera 224 (with multi-angle ring LED light source to reduce stacking shadows) to capture multi-angle images and acquire 3D data of the seedlings in the boxes. First, image noise reduction and contrast enhancement are used to weaken background interference. Then, an instance segmentation algorithm (such as Mask R-CNN) is used to separate the outline of individual seedlings from the stacked group, and their 3D shape is reconstructed by combining 3D point cloud data. Next, individuals that can be grasped are selected based on features such as the size and roundness of the substrate block. The world coordinates (X, Y, Z) of the geometric center and the optimal grasping posture (such as the orientation of the exposed surface of the substrate block) are calculated, and seedlings with severe occlusion or abnormal shape are excluded simultaneously. Finally, the coordinates and posture information of the selected effective seedlings are fed back to the robotic arm control system in real time, providing a positioning reference for accurate grasping in disordered scenes.

[0049] The transplanter is equipped with a seedling box at the front and a rear. The robotic arms work in pairs. When each pair grabs seedlings in the same seedling box, it achieves interference-free operation through "virtual partitioning + dynamic obstacle avoidance": First, the seedling box is divided into two dynamic sub-regions, left and right, based on visual recognition (the boundaries can be adjusted in real time as the number of seedlings decreases). Each arm is initially responsible for one region. The vision system and the arm-end encoder track the three-dimensional coordinates of the ends of the two arms and the seedlings in real time. The main controller predicts the intersection of trajectories through the fast collision detection algorithm GJK. If an arm needs to grab across regions, it triggers the "first-come, first-served" priority mechanism - the arm that has entered the target region completes the action first, while the other arm waits temporarily in the safe zone (≥30mm from the other arm's end) or fine-tunes its path. At the same time, the status is exchanged through a microsecond-level industrial bus to ensure that the action commands are synchronized, ultimately achieving efficient collaborative grabbing within the same box without interference.

[0050] Path planning is achieved using LiDAR (Light Detection and Ranging). LiDAR is essentially an active sensing technology that uses laser beams to perceive the environment and calculate the distance and position of targets. Its core function is to convert the three-dimensional spatial information of the physical world into computable "data," hence the name "LiDAR." The core logic of LiDAR for field path planning in transplanters is as follows: based on high-precision environmental perception, key field features are extracted through data processing; then, the path is planned in two layers—global and local; finally, closed-loop feedback ensures the accuracy of path execution and the quality of work. Compared to traditional "pre-programmed paths" (fixed row spacing, unable to avoid obstacles) or "visual navigation" (highly affected by lighting), the LiDAR solution is more adaptable to the complex and dynamic environment of the field and is one of the core technological directions for future intelligent transplanters.

[0051] The core components of LiDAR include a laser emitter, an optical receiver, a time measurement unit, and a signal processing unit. The entire system calculates the target distance using the "time of flight of light," and the specific process is as follows: The first step is to emit a laser beam: The laser emitter (such as a semiconductor laser) emits pulsed laser beams at a fixed frequency (tens of thousands to millions of times per second) towards the target area. The laser beam spreads into extremely fine "points" (typically millimeters in diameter), covering the sensing range. The second step is laser reflection: After the laser beam contacts an object (such as the ground, trees, vehicles, or crops), it is reflected by the object's surface, forming "reflected light." The third step is to receive the reflected light: The optical receiver (such as a photodiode) captures the reflected light and records its "time of arrival." The fourth step is to calculate the distance and position: Based on the physical law of "constant speed of light," the straight-line distance between the LiDAR and the target point is calculated using the formula: distance = (speed of light × laser round-trip time) / 2. Simultaneously, combined with the LiDAR's own position (such as the coordinates on the device) and the laser emission angle, the three-dimensional spatial coordinates (X / Y / Z) of the target point are further calculated. By continuously emitting and receiving lasers, LiDAR generates a massive number of "three-dimensional coordinate points" in a very short time (such as 10-20 times per second). The collection of these points is what we commonly call "point cloud" - point cloud can intuitively restore the three-dimensional features of a target, such as the outline, position, and height, like the outline of obstacles such as field ridges and stones, the shape of vehicles, and the undulations of terrain.

[0052] LiDAR is essentially a sensor that uses lasers to map the three-dimensional world. Its core value lies in converting the spatial information of the physical environment into digital signals, providing intelligent devices (such as transplanters) with the ability to perceive the environment in a "visible and accurate" way. In the agricultural field, it is not only the "eyes" for transplanter path planning, but can also be used for crop growth monitoring, yield estimation, soil topography mapping, and other scenarios. It is one of the key technologies driving the upgrade of agriculture from "manual operation" to "intelligent unmanned operation".

[0053] The LiDAR path planning of the intelligent fully automatic rhizome transplanter for Chinese medicinal herbs, taking a row spacing of 90cm and an operating speed of 1.2m / s as an example, is as follows: Hardware Installation: A 16-line LiDAR (120° forward field of view, 20m range) is mounted on the roof, and an 8-line LiDAR (scanning furrows downwards) is mounted on the side of the machine, along with an IMU and an incremental rotary encoder 148. The IMU (Inertial Measurement Unit) is a core "attitude and motion sensing component" in intelligent equipment such as transplanters. Its main function is to measure the equipment's acceleration and angular velocity in real time, assisting in positioning, attitude judgment, and path deviation correction. It is a key auxiliary hardware component in LiDAR path planning to "ensure driving accuracy." In field operation scenarios, although LiDAR can achieve environmental perception and positioning, it suffers from "positioning drift" problems (such as the accumulation of point cloud matching errors after long-term operation). Simultaneously, transplanters may face dynamic situations such as bumps (ridge surface undulations), steering, and speed changes. LiDAR alone cannot capture its own "attitude changes" (such as whether it is tilted or what the steering angle is) in real time. The incremental rotary encoder 148 is a core sensing component that calculates the equipment's travel distance and speed by measuring the rotation state of the power gears. Its essence is to "convert the mechanical rotational motion of the wheel into an electrical signal", providing the equipment with basic data on "its own movement distance". It is an important aid to LiDAR and IMU (inertial measurement unit) to jointly ensure the accuracy of path planning.

[0054] Data processing: Statistical filtering removes weed noise. ANSAC (Random Sample Consensus) is a classic algorithm used to accurately extract the target model (such as the ground or crop row lines) from data containing noise and outliers. The ANSAC algorithm is used to separate ground points, thereby fitting the ridge centerline (global reference path), separating ground points (ridges, field ridges) from non-ground points (crops, stones), avoiding interference from ground undulations in path calculation, and fitting the edge lines of furrows to determine the transplanter's "driving boundary" (preventing wheels from crushing furrows). Global path: Planned in a "reciprocating" manner, with a row spacing of 90cm and a turning radius of 3m (to avoid crushing seedlings). Local path: When LiDAR detects a rock (obstacle) with a diameter >10cm in the field, it travels through A... The algorithm generates an "obstacle avoidance path" (bypassing the stone from the left / right side, maintaining a distance of ≥30cm from the stone), while pausing the seedling transplanting action, and resuming the operation after bypassing the obstacle; Feedback Correction: If the IMU detects a lateral deviation of 4cm in the transplanter, then MPC (Model Predictive Control) is an advanced control method based on "rolling optimization". Its core logic is: by establishing a mathematical model of the controlled object (such as a transplanter), predicting its motion state over a future period, then solving for the "optimal control sequence" through an optimization algorithm, and executing only the first step of the sequence, then repeating this process, thereby achieving high-precision and robust path tracking. It is particularly suitable for dealing with the "nonlinear, time-varying, and constrained" characteristics of transplanters traveling in the field (such as changes in soil resistance, wheel slippage, and steering delay). Based on this algorithm, the transplanter's steering is controlled, correcting the deviation to <2cm within 1s, ensuring that the row spacing error of the transplanter is ≤±3cm. Compared to traditional "pre-programmed paths" (fixed row spacing, lacking dynamic obstacle avoidance capabilities) and "visual navigation" (susceptible to light intensity and weather changes), the LiDAR (Light Detection and Ranging) solution can accurately perceive dynamic obstacles and complex terrain in the field, and is more adaptable to the complex and ever-changing working environment in the field, providing stable and reliable navigation support for intelligent transplanting.

[0055] The intelligent fully automatic rhizome transplanter of this invention uses batteries as its power source. The batteries are housed in a battery box 113 and sealed with a top cover to prevent water ingress. The controller is integrated into the control box, and the main controlled components include a walking motor, a seedling feeding motor, and a seedling delivery robot, which respectively realize the transplanter's movement, seedling transplanting, and seedling loading operations. The system adopts a modular design, breaking the system down into functionally independent modules with clear interfaces. This achieves decoupling and reuse, simplifies maintenance, improves expansion flexibility and development efficiency, and reduces the lifecycle management cost of complex systems.
