The Automated Guided Vehicles have a built-in magnetic navigation sensor to track the navigation into the right path and perform well.
How does the magnetic navigation sensor function?
The magnetic navigation sensor can detect and report the position of the magnetic field along its flat axis. The sensor is designed for AVGs and mobile robots that help carry things or products faster than humans. It has a patented sensor delivering angle measurement with precision and position accuracy.
The AVG follows a track from an adhesive magnetic tape affixed on the path or floor where it passes. The magnetic sensor measures the distance from the center of the tape and delivers information to the motor controller. The estimated measurement delivered is adjusted by the steering wheel to guide the vehicle to stay at the center of the track.
The magnetic markers are positioned on the right and left sides of the track. These markers' role is to give the AVG the location information to make a fork left or right decision and stop.
Magnetic track guiding
Magnetic tapes are line-following techniques for AVG. There are other 2 main techniques, such as:
- induction wire guide
- optical
Why use a magnetic guide sensor for AVG
The magnetic guidance sensors deliver a signal about the position deviation of AGV that passes the magnetic path. It provides an output voltage proportional to the turn rate at the magnetic path center axis.
Magnetic guidance sensor is typically used for Automated Guided Vehicles because it can deliver a highly accurate and reliable way of navigation. Here are the functions of the magnetic guidance sensor in AVG:
- detecting the magnetic field embedded in the floor
- allowing the vehicle to exactly follow a predetermined path without being interrupted by obstructions, such as:
- dust
- dirt
- lighting conditions
making it a strong option for industrial settings where constant navigation is required.
There are important reasons for using magnetic guidance sensors for your AVGs, such as:
High precision. The magnetic sensor detects smaller changes in the magnetic field that lead to AVG's precise positioning along the specified path.
- Reliability. Unlike vision-based systems that are affected by clutter or lightning, magnetic sensors cannot easily be disrupted by these environmental factors. Instead, the AVG continually works with the reliable magnetic guidance sensor.
- Easy installation. The magnetic tape is easy to install on the floor to create a guide path to simplify the setup process.
- Durability. The magnetic sensors are powerful and withstand harsh industrial environments.
How does a magnetic sensor work?
The magnetic tape is implanted on the floor along the path where AVG passes by. The AVG follows the magnetic tape which serves as a guide to make it perform well. The magnetic sensor placed on the AVG detects the magnetic field generated by the tape. The AVG control system has sensor data that adjusts the steering for the vehicle centered on the magnetic path.
Is a magnetic navigation sensor good?
Magnetic navigation sensors are a good option for your magnetic guiding work. The detection feature of the magnetic guide makes it perform well with precision and in countless positions. The magnetic sensor reliably works in special situations where potential debris and dirt are possible.
Conclusion
The magnetic sensor is a robust device designed for industrial settings. The insensitivity feature of the magnetic sensor does not affect lighting conditions, while performing its work. It is easy to install and modify when following the guiding path. Placing the magnetic tape for the intended route of AVG makes it work accurately. It works on robotic systems and for automated guided vehicles.
