Recent Advances in Agentic Agri-Robotic Phenotyping: A Perspective Review from Fragmented Multimodal Sensing to Unified PhenoAgent Intelligence
🤖 AI Summary
This study addresses the fragmentation of crop phenotyping systems and the limitations of isolated trait estimation by reformulating phenotyping as an intelligent problem grounded in seed–soil–plant–environment–management synergy. To this end, it introduces PhenoAgent, a novel framework that deeply integrates robotic platforms, multimodal sensing, deep learning, and agentic AI to establish a unified paradigm spanning data acquisition to closed-loop decision-making. This integration enables uncertainty-aware reasoning and actionable agronomic management support. By defining an interpretable, scalable, and deployment-oriented pathway for crop intelligence, this work explicitly identifies critical challenges such as data scarcity and benchmarking. Ultimately, it advances the field from single-trait estimation toward unified crop intelligence.
📝 Abstract
This review examines the evolution of plant phenotyping from conventional manual trait measurement to high-throughput, robotic, and artificial intelligence-driven crop monitoring. Despite significant advances in imaging, autonomous platforms, multimodal sensing, and deep learning, current phenotyping systems remain fragmented across sensing modalities, crop traits, growth stages, environments, and management objectives. We therefore frame phenotyping as an integrated \emph{seed-soil-plant-environment-management} (SSPEM) intelligence problem, where crop performance reflects interactions among seed quality, root-zone conditions, plant development, environmental exposure, and management actions. The review synthesizes conventional, high-throughput, robotic, and AI-driven phenotyping approaches, highlighting their capabilities and persistent limitations in temporal integration, multimodal reasoning, biological interpretation, and actionable decision support. Building on this analysis, we introduce a conceptual PhenoAgent framework that extends phenotyping beyond the estimation of isolated traits to evidence-based crop-state interpretation, uncertainty-aware reasoning, and management-oriented support. The PhenoAgent concept primarily brings together scattered advances in phenotyping to deliver insights ranging from detailed to high-level, such as what is happening in the crop, why it might be occurring, what evidence is missing, and what actions or additional measurements should be considered. We also discuss challenges in dataset scarcity, annotation, benchmarking, model generalization, and explainability. By linking multimodal phenotyping with agentic AI and closed-loop decision support, this review outlines a path to interpretable, scalable, and deployment-oriented crop intelligence.
