DADISICK LiDAR: Enabling Accurate Collision Warning and Navigation for AGVs and Forklifts

By emitting laser pulses and measuring their time of flight (TOF), LiDAR sensors can capture precise distance information and build a map of the surrounding environment in real time . For example, in automated guided vehicles (AGVs), scanning LiDAR sensors not only provide high-precision positioning for navigation but also detect obstacles and adjust the path automatically to avoid collisions .

The DADISICK LDS2030B5-5S single-layer scanning LiDAR is designed with this principle in mind. It uses TOF measurement, provides a 300° scanning range, 0.5° angular resolution, and a 25 Hz scanning frequency. It supports Ethernet and I/O interfaces, making it highly adaptable for integration in AGVs and forklifts. This article introduces how the LDS2030B5-5S enhances forklift collision avoidance and AGV laser navigation from a technical and application perspective.

For instance, the “Object Detection (OD)” function in advanced forklift collision systems relies on 2D LiDAR to monitor the travel path, detecting shelves, cargo, vehicles, or people. When a risk is identified, the system immediately triggers a visual or audible alert .

Key features of LiDAR-based forklift collision systems include:

● Multi-zone detection: Configurable warning and danger zones tailored to the work environment.

● High accuracy: Real-time scanning of static and dynamic obstacles ensures timely alerts .

● Emergency intervention: Systems can automatically trigger braking or speed reduction to prevent accidents .

By combining real-time scanning with adaptive warning zones, LiDAR significantly reduces the risk of forklift collisions in busy warehouse operations.

When obstacles are detected along the travel path, the AGV can automatically re-plan its route or pause its movement. This provides AGVs with true obstacle avoidance capabilities, improving transport efficiency while reducing human intervention.

Advantages of 2D LiDAR sensors for AGV navigation include:

● Lighting independence: Performance is unaffected by ambient light changes.

● High precision: Accurate distance and angle measurements for reliable positioning.

● Wide field of view: Coverage up to 300° enables comprehensive monitoring.

In practice, multiple LiDAR sensors are often mounted on an AGV to achieve near 360° perception . With high refresh rates (25 Hz or above) and fine angular resolution (0.5° for the LDS2030B5-5S), AGVs can quickly identify and avoid even fast-approaching obstacles, making LiDAR-based navigation the mainstream solution in industrial automation .
