Abstract
Autonomous robots are increasingly used for data collection and monitoring in precision agriculture, but enabling non-specialist growers to assign them complex tasks remains a challenge. This talk presents our recent work using large language models (LLMs) to bridge that gap. First, we describe a system that translates natural-language mission requests into robot-executable plans, following the IEEE Standard for Robot Task Representation and executed on a field robot via ROS2. Testing on an orchard testbed shows that LLMs can handle many missions well but may struggle with spatial reasoning and optimization problems, a gap we close by embedding a hand-designed solver into the pipeline. Owing to the inherent ambiguity of natural language, we introduce a second architecture that formally verifies whether a generated mission plan actually matches the user’s intent, using an independent LLM to produce a linear temporal logic specification checked against the plan via the SPIN model checker. Evaluated on both lab missions and real prompts from farm workers, the system detects and self-corrects misalignments without human intervention, moving toward robots that growers can instruct in plain language with confidence that the robot will do what was asked.
