Autonomous Planter Container Transfer Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural planting implements require frequent and labor-intensive refilling of seed and fertilizer supplies, which is inefficient and time-consuming, especially for autonomous machines operating in fields.
Innovation Solution
A control system for autonomous machines that includes an alignment sensor and a machine processor to manage the transfer of interchangeable product containers, allowing for efficient alignment, loading, and unloading of agricultural products between the machine and a supply station, enabling continuous operation without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional planters and seeders are used with manual refilling processes, then the implements can operate in the field, but the refilling process becomes slow and labor-intensive
Solution Approach 1:
The autonomous planter is equipped with sensors (container level sensors, alignment sensors) and automated mechanisms (transfer arms, container handlers) that enable it to autonomously detect when containers need refilling, navigate to the supply station, align with the station, and transfer containers without human intervention. This self-service capability eliminates manual refilling operations entirely.
Solution Approach 2:
Multiple product containers are pre-loaded onto the autonomous planter during setup or at the supply station before field operations begin. This preliminary action ensures that the planter has sufficient product supply to operate for extended periods without returning to the supply station, maximizing continuous productivity.
2Quantity of substance
If frequent refilling is performed manually, then product supply is maintained, but operational time is lost and labor costs increase
Solution Approach 1:
The autonomous planter maintains continuous product supply through automated container transfer mechanisms that operate without interrupting field work. The planter can autonomously return to the supply station, transfer containers, and resume operations seamlessly, eliminating operational downtime associated with manual refilling and ensuring uninterrupted product application.
Solution Approach 2:
The planter autonomously manages its own product supply by detecting container levels, navigating to the supply station, and performing container transfers without human intervention. This self-service capability eliminates operational downtime by maintaining continuous product supply throughout field operations.
3Extent of automation
If autonomous machines operate without automated container transfer, then the system remains simpler, but frequent manual intervention is required
Solution Approach 1:
The control system integrates multiple functions into a unified autonomous operation platform. The same control system that manages field operations (navigation, product application, speed control) also handles container transfer operations, alignment, and supply station interactions. This multi-functionality approach manages complexity by consolidating control rather than adding separate dedicated systems.
Solution Approach 2:
The autonomous planter uses its existing navigation and sensing capabilities to autonomously perform container transfer operations. The control system leverages available sensors (alignment sensors, level sensors) and actuators to execute self-service container management, avoiding the need for complex dedicated automated transfer systems while achieving full automation.

AI summary
A control system is operable to control an autonomous machine for autonomously applying one or more products to a jobsite in accordance with a set of operation instructions. The products are stored in one or more interchangeable containers which are initially located on a station. The control system broadly includes an alignment sensor and a machine processor. The alignment sensor is configured to sense and generate alignment data regarding a relative position of the station and a particular container that contains a particular product. The machine processor is configured to align the autonomous machine with the station and the particular container based on the alignment data from the alignment sensor, and transfer the particular container from the station to the autonomous machine; move the autonomous machine over the jobsite and apply the particular product from the particular container in accordance with the set of operation instructions; and align the autonomous machine with the station based on the alignment data from the alignment sensor, and transfer the particular container from the autonomous machine to the station.
