1Productivity
If traditional manual soil sampling methods are used, then comprehensive soil coverage can be achieved, but the sampling process becomes time-consuming and inefficient
Solution Approach 1:
The robotic platform autonomously navigates the field, collects soil samples, and performs analysis without continuous human intervention. The system self-manages the sampling process by automatically moving to predetermined coordinates, collecting samples, and transmitting data to the server for analysis, thereby achieving comprehensive soil coverage while significantly improving sampling efficiency and reducing time loss.
Solution Approach 2:
The patent replaces manual mechanical sampling with an automated robotic system equipped with sensors and actuators. The robotic platform uses electronic control systems and GPS navigation to substitute human-operated mechanical sampling, thereby increasing productivity while reducing the time required for sampling and analysis through automated operations.
2Ease of operation
If uniform fertilization is applied across the entire plot, then management is simplified, but nutrient precision and environmental sustainability deteriorate
Solution Approach 1:
The system divides the field into distinct management zones based on soil nutrient analysis and applies fertilization strategies tailored to each zone's specific needs. Rather than uniform treatment, each local area receives customized fertilization based on its measured nutrient status, thereby achieving precise nutrient management while maintaining operational simplicity through automated zone-based control.
Solution Approach 2:
The system changes the fertilization parameter (amount and type of fertilizer) based on spatial variations in soil nutrient levels. By adjusting fertilization parameters according to local soil conditions identified through robotic sampling and analysis, the system achieves precise nutrient management that improves both environmental sustainability and operational efficiency through data-driven decision-making.
3Measurement precision
If frequent soil sampling is performed to capture temporal variability, then nutrient monitoring accuracy improves, but resource consumption and operational complexity increase
Solution Approach 1:
The system performs preliminary soil sampling and analysis at the beginning of the growing season to establish baseline nutrient levels and identify management zones. This preliminary action allows the system to plan subsequent sampling activities more efficiently, reducing overall operational complexity while maintaining the ability to monitor temporal nutrient variability through targeted follow-up sampling at key growth stages.
Solution Approach 2:
The robotic platform enables continuous monitoring of soil nutrients throughout the growing season by systematically collecting samples at predetermined intervals and locations. This continuous action captures temporal nutrient variability without requiring complex manual intervention for each sampling event, as the automated system maintains consistent monitoring operations throughout the season, thereby improving measurement precision while managing operational complexity through routine automation.

AI summary
A system and method for intelligent soil sampling has for a novelty robotic system 100 that samples soil based on the generation of sampling points through advanced artificial intelligence algorithms. The robotic system 100 comprises a robotic platform 101 with sampling modules 103, 105 and 108, which communicates with a server 111, that consists a localization module 113 containing artificial intelligence algorithms based on satellite images from multiple spectral channels and/or images from high-resolution drone for a given parcel 301, generates zones and determines the coordinates of points as the best representatives of the zones to take place efficiently and quickly sampling the land. Intelligent sampling takes place through several steps where the sampling limits are defined, so a mask is placed on a given plot, after which a pixel matrix with vegetation indices is formed, which is then normalized and K-mean algorithm in different spatial resolutions is worked on with calculation of probability that each pixel 315, 316 belongs to one of the K zones, taking into account its environment with a different number of pixels, where each pixel 315, 316 is associated with changes in spatial resolutions 311, 312, 313, diagonally 314, associated with new values of affiliation probabilities and finally in step 317 a consensus is reached where the final zones are determined and the probability of affiliation of pixels 315, 316 to zones is estimated based on local histograms of matrix entities 311, 312 and 313.
