Autonomous Work Machine Turn Control Using Target Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous work machines lack efficient turn control mechanisms, often turning randomly near boundaries or not considering target object distribution, leading to inefficient operation in work areas.
Innovation Solution
An autonomous work machine equipped with an obtainment unit to determine target object distribution, a determination unit to decide turn direction based on this distribution, and a control unit to execute turns at appropriate timings during travel, ensuring the machine turns in alignment with the target object distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If random turn direction and turn angle are used during autonomous travel, then the autonomous work machine can navigate boundaries, but it may turn toward already mowed areas resulting in inefficient operation
Solution Approach 1:
The determination unit receives information about target object distribution (unmowed area distribution) and uses this feedback to determine turn direction and turn angle. This feedback mechanism ensures the autonomous work machine turns toward areas with higher target object distribution, avoiding already mowed areas and improving work efficiency while maintaining autonomous navigation capability
Solution Approach 2:
The turn direction and turn angle are dynamically adjusted based on real-time target object distribution information rather than being fixed or random. This dynamic adaptation allows the autonomous work machine to optimize its turning behavior according to the actual work area conditions, preventing turns toward already mowed areas while maintaining navigation flexibility
2Device complexity
If turn control is not adjusted according to target object distribution, then the control system remains simple, but the autonomous work machine cannot efficiently operate in the work area
Solution Approach 1:
The determination unit serves multiple functions: it receives target object distribution information, processes this information, determines turn direction, determines turn angle, and outputs control signals. This multi-functionality allows the system to improve work efficiency through intelligent turn control without proportionally increasing device complexity, as a single determination unit handles all turn-related decision-making

AI summary
An autonomous work machine that works on a target object in a work area while performing an autonomous travel operation in the work area, comprises an obtainment unit configured to obtain a distribution the target object of the work, a determination unit configured to determine a turn direction of the autonomous work machine in accordance with the distribution of the target object, and a control unit configured to control the autonomous work machine so that the autonomous work machine will turn in the turn direction at a turn timing during the autonomous travel operation.
