Working Robot Magnetic Field Search for Wire Detection Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working robots used in fields with installed wires may suspend operations if the wire magnetic field becomes undetected by the magnetic sensor, even if the field is generated. This can lead to inefficient work progress as the robot may not immediately resume operations when the field becomes detectable again.
Innovation Solution
The working robot is configured with a control unit that executes an operation-suspending process when the wire magnetic field is undetected. The control unit then performs a first magnetic field searching process by moving the robot straight in a specific direction and assessing if the field is detected, and if not, a second searching process is conducted to ensure the field is detected before resuming operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the working robot suspends operations when the wire magnetic field is undetected, then the reliability of operation is improved, but the productivity deteriorates due to unnecessary suspension when the field is actually generated
Solution Approach 1:
The control unit performs preliminary actions by executing a first magnetic field searching process (moving the body straight by first distance) and second magnetic field searching process (moving in opposite direction by second distance) before suspending operation. This preliminary detection attempts to resolve temporary undetection issues caused by positional relationships, thereby avoiding unnecessary suspensions and maintaining productivity while ensuring reliability.
2Speed
If the working robot immediately suspends operations when magnetic field detection fails, then the response speed is improved, but the loss of time increases due to repeated suspensions and resusions
Solution Approach 1:
Before suspending operations, the control unit performs preliminary magnetic field searching processes that move the body in straight lines by predetermined distances in opposite directions. This preliminary detection resolves temporary undetection issues caused by positional relationships between the magnetic sensor and wire, reducing repeated suspensions and minimizing work interruption time while maintaining fast response.
3Measurement precision
If the control unit performs multiple searching processes to detect the wire magnetic field, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The control unit executes a first magnetic field searching process (moving body straight by first distance) and second magnetic field searching process (moving by second distance in opposite direction) as preliminary detection steps. These structured searching processes systematically change the positional relationship between the magnetic sensor and wire, improving detection accuracy while maintaining manageable control complexity through automated sequential execution.
Solution Approach 2:
The control unit performs periodic magnetic field detection by executing searching processes at regular intervals - first moving the body straight by first distance, then moving by second distance in opposite direction. This periodic action systematically explores the magnetic field environment, improving detection precision through repeated measurements while the automated periodic nature keeps control complexity manageable.

AI summary
A working robot may include a body, a movement unit, a working unit, a magnetic sensor supported by the body, and a control unit. The control unit may be configured to execute a working operation of causing the working unit to work while causing the movement unit to move the body. The control unit may execute, during the working operation, an operation-suspending process of suspending the working operation when a predetermined operation-suspending condition is satisfied, a first magnetic field searching process of causing the movement unit to move the body straight in a first linear direction by a first distance and assessing whether a wire magnetic field is detected by the magnetic sensor after the operation-suspending process, and an operation-resuming process of resuming the working operation when the wire magnetic field is detected by the magnetic sensor.
