Working Robot Route Control for Predictive Charging Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working robots face challenges in forming continuous and aesthetically pleasing working tracks while managing control loads when battery charge becomes insufficient during operations.
Innovation Solution
A controller system that predicts battery depletion mid-task and adjusts travel routes or working conditions to ensure continuous operation, integrating GNSS for precise location tracking and optimizing travel and working paths to minimize control load and maintain track integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the working robot continues working without interruption, then productivity is improved, but battery charge becomes insufficient causing operation interruption
Solution Approach 1:
The control unit predicts battery charge levels in advance before the robot actually runs out of power. By calculating remaining charge based on current consumption rates and planned work routes, the system performs preliminary charging actions (returning to charging base) before charge depletion occurs, ensuring continuous operation without interruption
2Reliability
If the working robot returns to charging base frequently, then battery charge is maintained, but working time is reduced and productivity decreases
Solution Approach 1:
The control unit calculates precise charge requirements for completing remaining work tasks and only returns to charging base when necessary (when predicted charge becomes insufficient). This partial action approach avoids unnecessary charging trips while ensuring operation continuity, optimizing the balance between reliability and productivity
3Reliability
If the working robot changes working route to reach charging base, then charge is replenished, but control complexity increases
Solution Approach 1:
The control unit continuously monitors battery charge levels, work progress, and charge consumption rates, using this feedback to dynamically adjust the working route. When charge becomes insufficient, the system calculates the optimal route to the charging base and automatically updates navigation, simplifying control through systematic feedback-based decision making
Data Source
AI summary
A working robot includes a processor. The processor is configured to form a working track along a traveling route for autonomous travel, recognize a location of a charging base configured to charge a battery as a drive source of the working robot, and set a working traveling route in a working section virtually defined and a charging traveling route between as actual location of the working robot and the location of the charging base. Before start of work for one working section, when it is predicted that an amount of charge becomes insufficient halfway through the work in the working section under a set working condition, the processor sets the charging traveling route, and controls traveling along the set charging traveling route.
