Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robotic systems lack intuitive and efficient methods for editing routes, which can become suboptimal due to environmental changes or inefficiencies, necessitating the need for systems and methods that allow for quick and seamless route modifications.
Innovation Solution
The implementation of a robotic system that includes a user interface and non-transitory computer-readable storage medium with instructions to receive user input for route modifications, update routes using Bezier curves, and execute the modified routes, allowing for deletion, addition, and alteration of route segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional route editing methods are used, then route modifications can be made, but the process is time-consuming and lacks efficiency
Solution Approach 1:
The system pre-generates multiple candidate route segments between waypoints using pathfinding algorithms. When a user requests route editing, these pre-computed segments are immediately available for selection, eliminating the need to compute paths from scratch during the editing process.
Solution Approach 2:
The system creates visual copies of existing route segments and allows users to manipulate these copies through drag-and-drop operations. The copied segments can be repositioned, rotated, or replaced while maintaining the original route structure, enabling rapid iteration without reprogramming.
2Adaptability or versatility
If manual route editing is allowed, then routes can be customized, but the interface complexity increases
Solution Approach 1:
The system automatically performs pathfinding and route optimization when users place or move waypoints. The pathfinding algorithm runs autonomously to generate connecting segments, eliminating the need for users to manually configure path parameters or understand complex routing logic.
Solution Approach 2:
The system uses smooth curved transitions (spheroidal paths) between route segments instead of sharp angular joins. This creates visually appealing and physically realistic robot paths that naturally navigate around obstacles while maintaining continuous motion, simplifying the user's mental model of route behavior.
3Productivity
If route segments are deleted or modified, then route optimization is achieved, but maintaining route continuity becomes difficult
Solution Approach 1:
The system continuously monitors route integrity after user edits. When segments are deleted or moved, the pathfinding algorithm automatically detects discontinuities and generates corrective path segments to restore continuity, providing real-time feedback that the route remains valid for robot execution.
Solution Approach 2:
The system pre-calculates alternative path segments that can serve as backups or replacements. When users delete existing segments, these pre-computed alternatives are immediately available to maintain route continuity, preventing gaps in the robot's navigation path.
