Forklift AGV

Fully Automated Forklift AGVs with Integrated Safety Laser Sensors:

1. Forward Sensing Control

Forward sensing control systems help prevent collisions by using a range of detection technologies to monitor the path ahead. These systems commonly include ultrasonic sensors, infrared (optical) sensors, and physical bumper sensors.

• Ultrasonic sensors function similarly to radar, emitting high-frequency sound waves ("chirps") and measuring the time it takes for the echo to return. This allows the AGV to detect nearby obstacles and adjust its movement to avoid impact.

• Optical sensors operate using infrared emitters and receivers. They send out infrared signals and detect reflections to sense objects in front of the AGV. While similar in function to ultrasonic sensors, optical systems can be limited in coverage angles and may present installation and operational challenges.

• Bumper sensors are physical contact devices that serve as a backup safety mechanism, engaging only when other systems fail to prevent contact.

2. Combined Control

Combined control systems enhance safety by integrating both collision avoidance sensors and area control sensors. This dual-layer approach ensures comprehensive protection during operation.

• Collision avoidance sensors handle immediate object detection and response.

• Area control sensors monitor the AGV’s environment and coordinate movement with other AGVs to avoid interference.

Even if the area control system fails or is disabled, the collision avoidance system remains active, ensuring the AGV can still detect obstacles and prevent collisions.
