Autonomous Robot Overtaking Control on Shared Movement Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous moving bodies operating independently in the same environment face challenges in coordinating their movement paths, leading to reduced operational efficiency, especially when they move at different speeds along the same path, and lack of communication or centralized control complicates cooperative task execution.
Innovation Solution
An autonomous moving body equipped with an external sensor to recognize other moving bodies and determine whether to overtake based on their operation state, movement path, and task priority, using a movement control unit to adjust its path and speed to avoid collisions and optimize task execution without relying on a single system or communication with other bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If autonomous moving bodies operate independently without centralized control or communication, then device complexity is reduced, but coordination ability deteriorates
Solution Approach 1:
Each autonomous moving body independently determines overtaking opportunities by observing other bodies through external sensors and evaluating its own task priority, without requiring centralized control or communication with other bodies. This self-service approach reduces system complexity while maintaining coordination capability through individual decision-making based on observable states.
2Productivity
If autonomous moving bodies move at different speeds along the same path, then task execution flexibility is improved, but collision risk increases
Solution Approach 1:
The autonomous moving body performs preliminary observation of other bodies' states and positions before executing overtaking maneuvers. By evaluating the observed state and determining overtaking opportunities in advance, the system ensures safe execution of speed variations along the same path, preventing collisions while maintaining task execution flexibility.
3Productivity
If autonomous moving bodies overtake each other frequently, then task execution efficiency is improved, but operational stability deteriorates
Solution Approach 1:
The system continuously observes the states of other autonomous moving bodies and uses this feedback to determine appropriate overtaking opportunities. By basing overtaking decisions on real-time observed states rather than fixed schedules, the system achieves efficient task execution while maintaining operational stability through adaptive, context-aware maneuvers.
