Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in controlling the processing load necessary for movement control of mobile objects, such as vehicles or robots, leading to instability in navigation and route planning.
Innovation Solution
An information processing apparatus comprising an estimation unit, a generation unit, and a frequency control unit that estimates the location or posture of a mobile object, generates movement plans, and controls the frequency of plan updates based on load index information, including confidence levels, to balance processing loads and ensure stable movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the frequency of movement plan update is increased to improve responsiveness, then the processing load on the estimation unit increases, but movement stability deteriorates
Solution Approach 1:
The patent applies dynamics by making the movement plan update frequency variable rather than fixed. The frequency control unit dynamically adjusts the update frequency based on the load index information from the estimation unit, allowing the system to adapt its responsiveness to current processing conditions while maintaining stability when load is high.
Solution Approach 2:
The patent implements feedback control where the frequency control unit receives load index information from the estimation unit and uses this feedback to adjust the movement plan update frequency. This closed-loop control ensures that updates are performed at optimal intervals based on actual system state, preventing overload while maintaining responsiveness.
2Measurement precision
If the processing load on the estimation unit is increased to improve location/posture estimation accuracy, then the frequency of movement plan update decreases, but movement control responsiveness deteriorates
Solution Approach 1:
The system dynamically adjusts the movement plan update frequency based on the estimation unit's processing load and accuracy metrics. When estimation accuracy is high and load is low, update frequency increases to improve responsiveness. When load increases or accuracy decreases, frequency is reduced to prevent system overload.
Solution Approach 2:
The patent changes the parameter of update frequency based on the load index and estimation accuracy. By varying this parameter dynamically, the system optimizes the balance between estimation precision and control responsiveness, allowing high accuracy processing when needed while maintaining timely responses when conditions permit.
3Reliability
If the frequency of movement plan update is decreased to reduce processing load, then the estimation unit can maintain stable operation, but movement control adaptability deteriorates
Solution Approach 1:
The system uses dynamic frequency adjustment to maintain stability while preserving adaptability. Rather than using a fixed low frequency that would limit adaptability, the system adapts the frequency in real-time based on load conditions, ensuring stability during high-load periods while capturing necessary movements during low-load periods.
