AGV stands for Automated Guided Vehicle, a driverless handling device capable of automatically traveling along a predetermined path. It uses navigation and control systems to achieve automatic material transfer and is widely used in industrial and logistics fields.
It can be divided into fixed-path navigation (such as magnetic navigation and QR-code navigation) and free-path navigation (such as laser navigation and visual navigation). Fixed-path navigation requires pre-setting a physical path, whereas free-path navigation allows for autonomous path planning.
These technologies primarily include navigation and positioning technology, motion control technology, scheduling system technology, sensor fusion technology, and battery management technology. Together, these technologies ensure the AGV’s autonomous operation and efficient performance.
It is used for the automated transfer of raw materials and semi-finished products within the workshop, connecting various production processes to achieve automation of material flow. By integrating with the MES system, it responds to production rhythms, enhancing production flexibility and efficiency.
The main types include differential-drive, steerable-wheel drive, Mecanum-wheel drive, and tracked drive. Differential-drive offers simple control, while Mecanum-wheel drive enables omnidirectional movement, making it suitable for various site requirements.
AGVs can navigate and travel autonomously without manual operation, making them suitable for repetitive tasks with fixed routes. Traditional forklifts rely on manual driving, offering high flexibility but having their efficiency and safety affected by human factors, making them ideal for dynamic and complex environments.
Responsible for task allocation, path planning, traffic control, status monitoring, and fault handling of multiple AGVs; optimizing AGV operational efficiency, avoiding conflicts, and ensuring the orderly coordination of multiple devices.
The main types include lead-acid batteries, lithium batteries, and hydrogen fuel cells. Lead-acid batteries are low-cost but heavy; lithium batteries have high energy density and fast charging capabilities; hydrogen fuel cells offer long driving ranges and short refueling times.
Includes laser obstacle avoidance, infrared sensors, emergency stop buttons, audible and visual alarms, and physical anti-collision strips. These features can detect obstacles and either slow down or come to a complete stop, alerting surrounding personnel and preventing collision accidents.
Regularly check the battery status, clean the sensors, lubricate moving parts, calibrate the navigation system, and test the control systems and safety devices to ensure that all systems function properly and to extend the equipment’s lifespan.
Used in warehouse operations such as shelving, unshelving, sorting, and transshipment of goods, it works in conjunction with the sorting system to complete order processing. During peak sales periods, it helps handle high order volumes, enhancing both the efficiency and accuracy of logistics operations.
Primarily influenced by navigation methods, sensor accuracy, ground conditions, battery voltage stability, and software algorithms, these factors collectively affect the positioning accuracy of AGVs.
The scheduling system receives transportation task instructions from the WMS system, assigns tasks based on the real-time status of the AGV, and provides feedback on task execution. The WMS system updates inventory information according to the feedback, thereby achieving closed-loop management of logistics information.
The selection should be based on the weight, volume, and shape of the materials being transported. Light-duty AGVs are suitable for small items, while medium- and heavy-duty AGVs are ideal for pallets and large-sized goods. When making your choice, be sure to allow for a certain margin to ensure safe operation.
The main issues include navigation anomalies (inaccurate positioning), drive system failures (jerky driving), battery problems (reduced range), sensor malfunctions (failed perception), and communication failures (disconnection from the dispatch system).
It must meet cleanroom requirements (to prevent contamination), material traceability requirements (to record transportation information), explosion-proof requirements (in certain scenarios), and stability requirements (to avoid damage to materials), and comply with pharmaceutical industry standards.
The main types are graphical programming, text-based programming, and teach-in programming. Graphical programming is easy to use and ideal for quickly configuring paths; text-based programming offers high flexibility and is suitable for complex logic control; teach-in programming involves manually guiding the robot to record the path.
AGVs typically travel along fixed paths and have relatively low autonomy; AMRs, on the other hand, boast enhanced autonomous navigation and obstacle-avoidance capabilities. They can autonomously plan routes, adapt to dynamic environments, and offer greater flexibility—making them an advanced form of AGVs.
The trends are toward intelligence (enhanced autonomous decision-making capabilities), flexibility (rapid adaptation to diverse scenarios), integration (interconnection with robots and automated equipment), and energy efficiency (adoption of new energy sources).
The costs primarily include hardware expenses (vehicle body, sensors, batteries), software expenses (navigation algorithms, scheduling systems), integration costs (interfacing with other systems), and maintenance costs. Costs vary significantly depending on the specific configuration.
