Vehicle Guidance Technologies of AGVs
1. Laser Navigation
AGVs equipped with laser navigation systems use laser scanners to create a map of their environment. The laser sensors detect obstacles and allow the AGVs to navigate autonomously by following predefined paths or adjusting their routes in real-time.
2. Magnetic Tape Guidance
Magnetic tape guidance systems utilize strips of magnetic tape placed on the floor to define paths for AGVs to follow. The AGVs have sensors that detect the magnetic fields of the tape, allowing them to stay on course and navigate through a facility.
3. Vision-Based Navigation
AGVs can also be guided using vision-based navigation systems, which utilize cameras and image processing algorithms to analyze the environment. The AGVs can identify landmarks or markers to navigate and avoid obstacles in real-time.
4. Inertial Navigation
Inertial navigation systems use sensors such as accelerometers and gyroscopes to track the AGV's movement and orientation. This technology is particularly useful in environments where other guidance systems may be less effective, such as outdoor or unstable terrains.
5. Lidar Navigation
Lidar navigation systems use laser light to measure distances and create high-resolution maps of the surroundings. AGVs equipped with lidar sensors can navigate complex environments with precision and avoid collisions with obstacles.
6. GPS-Based Navigation
AGVs can also be guided using GPS-based navigation systems, which rely on satellite signals to determine the AGV's position. This technology is commonly used in outdoor environments where GPS signal reception is strong.In conclusion, AGVs utilize a variety of vehicle guidance technologies such as laser navigation, magnetic tape guidance, vision-based navigation, inertial navigation, lidar navigation, and GPS-based navigation to navigate through different environments autonomously. Each technology has its own advantages and limitations, and the choice of guidance system depends on the specific requirements of the application.
