Case Study | Multi-vehicles Collaborative Operation, VisionNav Robotics Empowers Machinery Manufacturing Enterprise to Realize Automatic Factory Logistics
Date of issue:2022 / 05 / 12

Today, we will share the story of VisionNav Robotics with its autonomous pallet stacker enabling the well-known mechanical equipment manufacturing company to realize the transformation of automated factory logistics.

The realization of digitalization and intelligence in the mechanical equipment manufacturing industry is the primary goal of the industrial manufacturing industry. However, the manufacturing of mechanical equipment is mostly discrete production with many types of products, many specifications and models, and complicated process procedures. There are many "deep water" scenarios in this industry.

Project Background

 

The customer mainly produces automation equipment. The operation site of this project involves multiple workshops, and materials in different locations have different requirements for inbound and outbound, requiring the realization of indoor and outdoor material handling and docking with the automated AS/RS warehouse.



Project Solutions

VNSL Series Pallet Stackers + Robot Control System

 

VisionNav Robotics configures many VNSL series AGV forklifts and robot control system to complete various procedures, such as parts transfer between #1 and #2 workshops, material transfer from semi-finished product warehouse to transfer workshop, and transfer from semi-finished product to work station.

The VNSL series of autonomous forklifts from VisionNav Robotics are equipped in the project, with a rated load of 1.4T. The narrow-body shape is specially designed for narrow aisles, which can meet the requirements of a 1500mm walking aisle on site; The steering wheel is available for 80° turning, it can also achieve non-stop driving in the minimum right-angle turning channel width of 1800mm.


In addition, the project is equipped with the robot control system independently developed by VisionNav Robotics, which is connected to the customer's MES      system to realize various functions, such as real-time task management, detection of autonomous forklift operation and storage inventory status, multi-vehicle  scheduling, and planning of optimal transfer routes.

Project Process

Inbound: The customer's project site is divided into the inbound at the pick-up area and the inbound at the temporary storage area; The inbound information of the pick-up area is sent to the robot control system of the unmanned forklift through MES, and the system will automatically dispatch the AGV forklift to complete the inbound requirements. The inbound at the temporary storage area is different from the inbound at the pick-up area. MES sends the barcode of the goods and the barcode of the storage location to the robot control system, the system then deploys an unmanned forklift to transport the goods to the storage location, and at the same time feeds back the information to the system to update the goods status and storage location status in real-time.

 

Outbound: The customer's project site is divided into outbound at the outbound port and outbound at the inbound port after sorting/full material, The MES will send the handling information to the robot control system of the autonomous forklift, and the system will deploy the autonomous forklift to go to the corresponding area to complete the delivery operations.

 

Project Achievement

Multi-vehicle Collaborative Operation

Optimal Routes Planning to Improve Logistics Efficiency

After the project is launched, the robot control system is connected to the MES system of the customer, which can update and detect information about goods and warehouse location in real-time, reduce the risk of goods transshipment & warehousing errors, and improve the accuracy of material transshipment by more than 50%; At the same time, through the system deployment, autonomous forklifts can seamlessly connect with various automation equipment such as hoists, rolling doors, and conveyor lines, plan optimal operation paths, reduce waiting time for forklifts, and cooperate with multiple vehicles to effectively improve material handling efficiency by 30%.

High Precision Visual Navigation and Positioning

Respond to Complex Scenarios Where Man-machine Mixes Flexibly

The project site covers multiple scenarios like pick-up areas, temporary material storage areas, outbound areas, and so on. There is often staff coming and going in the width-limited channel, and the environment where man-machine mixes is complicated. The VNSL series autonomous forklift from VisionNav Robotics use high-precision visual navigation and positioning and laser end-sensing technology to sense operating environment information in real-time, so as to respond to complicated scenarios flexibly and efficiently. At the same time, it is equipped with multiple obstacle avoidance designs to ensure the safety of people, vehicles, and goods.
