Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile robots face limitations in speed due to the need to immediately stop when encountering unexpected obstacles in their path, which is often addressed by predicting blind spots and adjusting path and speed accordingly.
Innovation Solution
A mobile robot control device and method that senses the path using sensors and adjusts the path or speed of the robot when a blind spot is detected, by creating a virtual obstacle area and modifying the robot's path to avoid it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobile robot increases its speed to improve productivity, then the productivity is improved, but the robot cannot stop immediately when encountering unexpected obstacles in blind spots, increasing collision risk
Solution Approach 1:
The controller proactively determines a virtual obstacle area in advance based on blind spot information before the robot encounters actual obstacles. By pre-defining this safety zone and adjusting path or speed in advance, the system enables higher operating speeds while maintaining the ability to prevent collisions, thus resolving the contradiction between productivity and safety
Solution Approach 2:
The patent introduces a virtual obstacle area as an intermediary concept between the physical robot and actual obstacles. This virtual zone acts as a buffer that allows the robot to operate at higher speeds by providing提前 warning and control adjustments, mediating between the need for speed and the need for collision avoidance
2Reliability
If the mobile robot maintains a limited speed to ensure safety, then the collision avoidance capability is improved, but the productivity decreases
Solution Approach 1:
The controller dynamically adjusts the robot's speed or path based on the determined virtual obstacle area and actual operating conditions. Rather than maintaining a fixed limited speed, the system optimizes speed in real-time, allowing higher speeds when safe and reducing speed only when necessary, thus improving productivity while maintaining safety
3Measurement precision
If the mobile robot uses sensors to detect obstacles, then the measurement precision is improved, but the robot cannot detect obstacles in blind spots, reducing reliability
Solution Approach 1:
The patent creates a virtual copy of the obstacle detection concept by determining a virtual obstacle area based on blind spot information. Instead of relying solely on physical sensors to detect actual obstacles, the system creates a virtual representation of potential obstacle zones, enabling the robot to anticipate and avoid obstacles in areas where sensors cannot directly detect them
