机器人可自动采样分析土壤，10分钟出结果，助力精准农业。
Towards Autonomous In-situ Soil Sampling and Mapping in Large-Scale Agricultural Environments
- 机器人分采样与分析两部分，实现田间实时作业
- 每样本50克、200毫米深，10分钟内完成pH与大量元素检测
- 适合大规模农场，提升施肥效率与可持续性
传统土壤采样与分析方法耗时耗力，空间分辨率低，难以满足大尺度精准农业需求。为此，我们提出一种机器人系统，实现土壤关键属性的实时采样、分析与制图。系统包含两个核心子系统：用于精准自动化田间采样的采样获取系统（SAS）和用于实时分析的样品分析实验室（Lab）。在澳大利亚大型农场开展的广泛实地测试验证了系统性能。实验结果表明，SAS可稳定获取50克重、深度达200毫米的土壤样本，而Lab可在10分钟内完成每个样本的pH值及大量元素检测。该系统为农民提供及时的数据驱动洞察，显著提升土壤管理与肥料施用的效率与可持续性。
原文摘要 · Abstract (English)
Traditional soil sampling and analysis methods are labor-intensive, time-consuming, and limited in spatial resolution, making them unsuitable for large-scale precision agriculture. To address these limitations, we present a robotic solution for real-time sampling, analysis and mapping of key soil properties. Our system consists of two main sub-systems: a Sample Acquisition System (SAS) for precise, automated in-field soil sampling; and a Sample Analysis Lab (Lab) for real-time soil property analysis. The system's performance was validated through extensive field trials at a large-scale Australian farm. Experimental results show that the SAS can consistently acquire soil samples with a mass of 50g at a depth of 200mm, while the Lab can process each sample within 10 minutes to accurately measure pH and macronutrients. These results demonstrate the potential of the system to provide farmers with timely, data-driven insights for more efficient and sustainable soil management and fertilizer application.
