Semi-Autonomous Farm Robot Coordination for Delicate Plant Tasks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural tasks requiring dexterity and delicacy, such as trimming plants or picking fruits, pose challenges for autonomous robots due to variability among plants, making it difficult for them to perform these tasks safely and effectively without human intervention.
Innovation Solution
A system of semi-autonomous robots that deploy scout robots to gather vision data, analyze it to identify tasks, and then deploy worker robots to perform tasks autonomously unless a human operator is needed to ensure safety, allowing a small number of human operators to control a large fleet of robots by providing manual control interfaces when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous robots are used to perform agricultural tasks, then productivity is improved, but reliability deteriorates due to inability to perform delicate tasks safely
Solution Approach 1:
The system segments the robot fleet into different roles: scout robots that gather data and worker robots that execute tasks. This segmentation allows specialization where scout robots focus on data collection and worker robots on task execution, improving overall system reliability while maintaining productivity
Solution Approach 2:
A human-in-the-loop intermediary system is introduced that receives robot requests, assesses task safety requirements, and provides guidance or approval. This intermediary layer enables autonomous operation for routine tasks while ensuring human oversight for delicate operations, resolving the reliability concern
2Reliability
If human operators control robots manually, then reliability is improved, but productivity deteriorates due to limited human capacity to manage multiple robots
Solution Approach 1:
The system implements partial automation where only specific critical functions require human intervention while other functions operate autonomously. This allows human operators to manage multiple robot fleets simultaneously by delegating routine decisions to autonomous systems, maintaining reliability for critical tasks while improving overall productivity
Solution Approach 2:
The system employs feedback mechanisms where robots autonomously assess task requirements and only request human intervention when confidence thresholds are not met. This feedback loop enables automated decision-making for routine tasks (improving productivity) while ensuring human involvement when needed (maintaining reliability)
3Productivity
If robots perform delicate agricultural tasks, then productivity is improved, but object-affected harmful factors increase due to plant damage risk
Solution Approach 1:
Scout robots perform preliminary data collection and task assessment before worker robots execute agricultural tasks. This preliminary action includes identifying plant characteristics, task complexity, and potential risks, enabling the system to plan actions that maximize productivity while minimizing plant damage through informed decision-making
Solution Approach 2:
The system dynamically adjusts the level of human intervention and robot autonomy based on real-time task assessment and plant conditions. For delicate tasks, the system increases caution and human oversight, while for robust tasks, it maintains high-speed autonomous operation, thus improving productivity without increasing plant damage risk

AI summary
Implementations are described herein for coordinating semi-autonomous robots to perform agricultural tasks on a plurality of plants with minimal human intervention. In various implementations, a plurality of robots may be deployed to perform a respective plurality of agricultural tasks. Each agricultural task may be associated with a respective plant of a plurality of plants, and each plant may have been previously designated as a target for one of the agricultural tasks. It may be determined that a given robot has reached an individual plant associated with the respective agricultural task that was assigned to the given robot. Based at least in part on that determination, a manual control interface may be provided at output component(s) of a computing device in network communication with the given robot. The manual control interface may be operable to manually control the given robot to perform the respective agricultural task.
