Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rebar tying robots face significant processing loads and operational delays due to the need for correcting estimated positions based on sensor measurements, which can lead to inaccuracies in navigation.
Innovation Solution
A binding apparatus and system that utilize a map including estimated positions of intersection points to control traveling without the need for sensor-based corrections, using a rebar binding unit, traveling unit, and travel control unit to navigate with high accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If position correction based on sensor measurements is performed, then navigation accuracy is improved, but processing load and operational delays increase
Solution Approach 1:
The patent extracts and eliminates the position correction process from the navigation system. By using a pre-generated map with estimated intersection point positions, the system removes the need for real-time sensor-based position correction, thereby maintaining navigation accuracy while reducing processing load and operational delays
Solution Approach 2:
The patent applies preliminary action by generating a map with estimated intersection point positions before the binding operation begins. This pre-computed map allows the robot to navigate directly to target positions without performing real-time sensor corrections during operation, thus improving operational speed while maintaining position accuracy
2Measurement precision
If sensor-based position correction is performed, then position accuracy is improved, but computational requirements and processing time increase
Solution Approach 1:
The patent removes the complex sensor-based position correction computation from the navigation process. By relying on a pre-generated map containing estimated intersection point positions, the system eliminates the need for real-time computational correction, thereby reducing processing complexity while maintaining sufficient position accuracy for binding operations
