Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the robot controller detects installation failure based on robot operation feedback, then the detection capability for robot installation is improved, but the detection capability for transferring equipment installation is lost
Solution Approach 1:
The robot controller is designed to perform multiple detection functions: it can detect both robot installation status (through speed feedback signal comparison) and transferring equipment installation status (through position deviation detection during movement). This multi-functional approach resolves the contradiction by enabling the controller to maintain specialized robot detection capabilities while expanding to cover transferring equipment detection as well.
2Reliability
If the robot controller monitors transferring equipment installation state, then the durability of transferring equipment is improved, but the complexity of the control system increases
Solution Approach 1:
The robot controller utilizes its existing operational data (position feedback during robot movement) to simultaneously monitor transferring equipment installation status. Instead of adding separate monitoring systems, the controller serves itself by extracting additional diagnostic information from routine operational data, thereby improving reliability without proportionally increasing system complexity.
Solution Approach 2:
The detection function for transferring equipment is merged with the existing robot control and detection functions. The same circuitry that processes robot position feedback is also used to detect transferring equipment installation abnormalities, combining multiple functions into a single integrated system that reduces overall complexity.
3Measurement precision
If the robot controller compares measurement data with target data to detect abnormalities, then the accuracy of installation failure detection is improved, but the processing time increases
Solution Approach 1:
The robot controller prestores target position data indicating the correct installation state of the transferring equipment before actual operation. During robot movement, the controller simply compares real-time position feedback against these pre-stored targets, enabling rapid accuracy assessment without time-consuming calculations or complex real-time analysis.
Data Source
AI summary
A robot controller that controls an operation of a robot includes circuitry and memory equipment. The memory equipment stores target data indicating a target installation state of a transferrer that supports and moves at least one of the robot or a target object handled by the robot. The circuitry outputs to a display an input image showing a measurement position of an installation state of the transferrer together with an image of the transferrer. The circuitry receives measurement data of the installation state. The circuitry compares the measurement data with the target data to determine the presence or absence of the abnormality of the installation state.
