LS Unmanned Forklift Control System
Overall System Structure
With the rapid development of intelligent logistics and intelligent warehousing, automatic forklifts have emerged for saving the operation cost and improve the warehouse safety performance. Leishen has developed a complete set of unmanned forklift application systems that can be applied to large logistics storage centers based on lidar sensors, which can be effectively deployed in cargo handling on-demand indoor and outdoor requirements, such as ports, airports, factory warehouses and logistics centers, etc.
The system is compatible with most electrical forklifts which are with CAN bus access to the forklift driver. The overall system structure is shown in the picture below:
The system includes two parts:
- Intelligent dispatch and monitor system: the intelligent dispartch and monitor system is responsible for receiving the tasks from ERP/WMS warehous management system, and assign them to the forklifts standby, and monitoring the operation status of the forklift and report the status back to warehouse management system.
- Unmanned forklift control system: the unmanned forklift system is the execution unit in the entire application system. Each unmanned forklift can automatically complete the autonomous navigation and handling of target goods, automatic loading & unloading and intelligent identification of goods through the navigation tasks issued by the intelligent scheduling system. Each unmanned forklift body basically includes an autonomous positioning and navigation module, an underlying sensor integration and motion control module, a multi-protection alarm module, a power monitoring and autonomous charging module, functions such as automatic fork unloading and intelligent identification of goods during the tasks execution.

Automatic Forklift System Functions
The autonomous navigation function of the automatic forklift is mainly realized by the LiDAR 3D SLAM algorithm, which mainly includes 3D scene map construction, matching positioning, path planning and real-time obstacle avoidance navigation.
3D scene map construction
3D LiDAR and SLAM algorithm are used to complete the work scene map construction.
Matching and positioning
With IMU data, LiDAR is used to scan and collect the point cloud data and the scene map in real time for matching and positioning.
Path planning and real-time obstacle avoidance
Path planning and navigation is the core function of Automatic forklift. It uses a priori information of LiDAR detection, uses global planning to give the route of motion, and makes specific behavior planning according to the local planning function of obstacle avoidance information. And motion planning, and finally converted into a series of continuous navigation track target
Pallet and Container Identification
Depth camera and Lidar are used to identify the position of the pallets and container entrance, along with the encoder to monitor the accurate the position of the forklift. Ensure the goods can be loaded and unloaded accurately and the Automatic Forklift can enter and exit the container safely.
