Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-movement robots face hindrances in navigating through obstacles when the obstacle height exceeds their body height, limiting their ability to pass smoothly, especially in complex environments.
Innovation Solution
Equipping self-movement robots with first and second distance sensors to generate three-dimensional map information by overlaying spatial height data onto two-dimensional maps, allowing for smooth, safe, and efficient operation in combined mode by planning walking paths based on three-dimensional maps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the robot body height is increased to pass through obstacles, then the robot can navigate higher obstacles, but the robot cannot pass through low-height obstacles smoothly
Solution Approach 1:
The patent transitions from two-dimensional map information to three-dimensional map information by adding height dimension data. Distance sensors collect spatial height information above the working surface, and the control center overlays this height data onto the 2D map to generate 3D map information, enabling the robot to navigate obstacles of varying heights effectively
2Device complexity
If two-dimensional map information is used for navigation, then the system is simple, but the robot cannot accurately navigate three-dimensional obstacles
Solution Approach 1:
The patent enhances the map system by adding the height dimension to traditional 2D maps. Distance sensors mounted on the robot body collect spatial height information above the working surface during movement. The control center processes this height data and overlays it onto the 2D map information to generate comprehensive 3D map information, improving obstacle navigation accuracy while maintaining system simplicity
3Loss of information
If distance sensors are added to collect spatial height information, then three-dimensional map information can be generated, but the device complexity increases
Solution Approach 1:
The patent employs distance sensors that serve multiple functions: they collect both two-dimensional map information of the working surface and spatial height information above the working surface. This multi-functional approach reduces the need for separate sensor systems, thereby minimizing device complexity while comprehensively capturing spatial data for 3D map generation
