Autonomous Forklift: Autonomous Positioning, Navigation, and Operational Safety Protection

Scenario Requirements and Pain Points:
In automated warehousing and logistics, unmanned forklifts often need to operate in narrow aisleways between shelves and in busy transfer zones. Traditional laser reflector-based navigation requires installing numerous reflectors on walls and shelves, a process that is both labor-intensive and costly to maintain. Moreover, if the positions of the shelves change, the navigation system must be reconfigured from scratch. Additionally, forklifts are heavy and have significant inertia; if they fail to promptly detect suddenly appearing personnel or scattered goods while moving, they can easily cause serious safety incidents or even lead to shelf collapses.

Application Logic:
Mount an F30 / F50 / F60 / N70 navigation and obstacle-avoidance laser radar on the front or top of the unmanned forklift’s body. The radar performs high-frequency scans of the surrounding environment, such as walls and shelf columns.

SLAM Navigation: The radar outputs a high-precision point cloud of the environment’s contour via Ethernet, enabling the onboard controller to perform SLAM (Simultaneous Localization and Mapping) computations. This allows for centimeter-level autonomous positioning and path planning without the need to install reflectors.
Dynamic obstacle avoidance: At the same time, leveraging the radar’s multi-zone functionality, a dynamic safety collision-avoidance zone is set up in the forklift’s direction of travel (adjusting with speed changes). Once an obstacle is detected, the system immediately triggers deceleration or stopping.

Technological Advantages:
The F30/F50/F60/N70 series, with its integrated navigation and obstacle-avoidance design, greatly simplifies the sensor architecture of unmanned forklifts and reduces overall vehicle costs. Its fine angular resolution of 0.25° enables precise detection of subtle features such as shelf legs, ensuring high-precision operation and accurate pallet docking within aisles. Meanwhile, with an impressive light interference resistance of up to 80,000 lux, these forklifts can maintain stable navigation—even under conditions of direct sunlight through skylights or in environments with intense outdoor light—without losing track or generating false alarms.
