Pallet Transport Robot Obstacle Avoidance

The intelligent rail-guided transport system connects transmission stations in different areas via specific tracks. Specialized transport vehicles travel along these fixed tracks, enabling three-dimensional, point-to-point transportation between stations. To improve the operational efficiency of the pallet transport robots, multiple robots can run simultaneously. To prevent collisions between these robots, Benewake has introduced a LiDAR obstacle avoidance solution, ensuring safe operation of the robots and reducing property damage.

Pallet Transport Robots in Automated Warehouses

In automated warehouses, multiple pallet transport robots operate on tracks at high speeds. To prevent collisions and safety incidents that could reduce the warehouse's operational efficiency, Benewake single-point LiDAR units can be integrated in four directions on the pallet transport robots. These LiDAR units detect obstacles and measure distances to other robots in real-time. When an obstacle suddenly appears or another robot stops, the LiDAR provides immediate distance feedback, allowing the system to promptly control the pallet transport robots to decelerate or stop.

Overhead Rail Vehicles

Following delivery instructions from the control center, intelligent vehicles travel along overhead rails to material delivery point A and transport the materials to station B via horizontal or vertical tracks. This achieves fast, contactless intelligent material transportation. To prevent collisions between multiple overhead rail robots during operation, two TF-Luna low-cost LiDAR distance measurement modules are installed at both the front and rear of the robots (as shown in the diagram) to detect distances. When an obstacle is detected during operation, the inspection robot triggers an alarm and decelerates or stops immediately, ensuring the safe operation of the overhead rail inspection robots.

Core Advantages
