Solution Overview

Problem

Existing methods for adjusting and calibrating agricultural robots require multiple test cycles in autonomous mode, leading to inefficiencies and interruptions, as parameters cannot be adjusted in advance and must be set on-site under real conditions.

Innovation Solution

A method that allows for temporary operation in semi-autonomous mode to adjust and calibrate operating parameters in real-time, allowing operators to manage and validate settings without interrupting autonomous work, thereby reducing the need for repeated cycles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If multiple test cycles are conducted in autonomous mode to adjust and calibrate parameters, then the robot can operate autonomously, but productivity decreases due to repeated interruptions and time consumption

Engineering Contradiction:
Improveautonomous operationVSAvoidwork efficiency
Core Design Contradiction:
Extent of automationVSProductivity

Solution Approach 1:

The system dynamically switches between autonomous mode and semi-autonomous mode based on the calibration needs. During normal operation, the robot works autonomously, but when parameter adjustment is needed, it transitions to semi-autonomous mode where the operator can intervene without completely taking control, thus maintaining productivity while enabling necessary adjustments

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The operator performs parameter adjustments and calibrations in advance during semi-autonomous mode before the robot resumes autonomous operation. This preliminary action prevents the need for multiple interruptions during autonomous work, as parameters are optimized beforehand

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If parameters are adjusted on-site under real conditions through multiple test cycles, then the operating parameters can be optimized for actual working conditions, but time is lost due to repeated trials and tests

Engineering Contradiction:
Improveparameter optimizationVSAvoidadjustment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The calibration process is integrated into the continuous workflow rather than being performed as separate, disconnected test cycles. The robot can perform calibration actions continuously during operation, and the operator can make adjustments without stopping the overall work process, maintaining continuous useful action while optimizing parameters

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system implements feedback mechanisms where the operator can observe the robot's performance in real-time during semi-autonomous mode and immediately adjust parameters based on actual working conditions. This feedback loop enables rapid parameter optimization without requiring multiple sequential test cycles

Inventive Principle:
Principle #23Feedback
