Engineering Contradiction Analysis
1Manufacturing precision
If a floating mechanism is added to the articulated robot to enable automatic center alignment, then the teaching accuracy is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces the mechanical floating mechanism with a sensor-based detection system. A sensor detects the position of the partner device, and a controller automatically calculates and adjusts the robot's movement to achieve center alignment, eliminating the need for complex mechanical floating structures while maintaining teaching accuracy.
