Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial robots face challenges in adapting to varying work objects and environments, leading to reduced work quality and increased operator labor when manually correcting robotic arm routes in master-slave systems.
Innovation Solution
A robot system that allows remote control of a robotic arm with real-time route correction capabilities, using a synthesized image of the scheduled route and captured images to guide the operator for precise adjustments, reducing operator labor and improving adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot operates automatically based on a preset program, then high speed and high accuracy are achieved, but the system cannot adapt when work objects vary or work environment changes
Solution Approach 1:
The system dynamically switches between automatic operation mode (for high speed and accuracy) and manual operation mode (for adaptability). The operation mode is not fixed but can be changed based on the work situation, allowing the robot to maintain high productivity during routine tasks while adapting to variations when needed.
Solution Approach 2:
The system provides real-time visual feedback through a monitor displaying the robot's current position and preset route. This allows the operator to observe the automatic operation and intervene when adaptation is needed, creating a feedback loop that combines automatic efficiency with human adaptability.
2Adaptability or versatility
If the operator manually operates a master arm in a master-slave system, then flexible adaptation to each work object is achieved, but significant time and labor are required
Solution Approach 1:
Instead of requiring full manual operation for the entire work process, the system uses partial manual action only when needed for route correction during automatic operation. The operator intervenes partially to correct specific portions of the route rather than controlling the entire operation, significantly reducing time and labor while maintaining adaptability.
Solution Approach 2:
The system performs preliminary action by presetting the robot's operation route in advance. This preset route handles the majority of the work automatically, and the operator only needs to make minor corrections when necessary, rather than manually controlling every movement from scratch.
3Adaptability or versatility
If the operator remotely controls the robotic arm during automatic operation, then route correction is possible, but suitable correction cannot be achieved unless the operator grasps in advance how the preset route is to be corrected
Solution Approach 1:
The monitor provides real-time visual feedback showing the robot's current position overlaid with the preset route. This feedback mechanism eliminates the need for the operator to predict corrections in advance, as they can directly observe the robot's position and make intuitive corrections based on visual information, greatly improving ease of operation.
Solution Approach 2:
The monitor serves as an intermediary between the automatic operation system and the operator. It translates the robot's position and preset route into visual information that the operator can easily interpret, facilitating smooth and intuitive route correction without requiring the operator to mentally calculate or predict the necessary adjustments.
