  1. Infiltration type: It infiltrates the bottom of the material cart, automatically attaches and detaches to deliver and retrieve materials.
  2. Traction type: It pulls the material cart through automatic attachment and detachment mechanisms at the rear.
  3. Self-unloading type: Equipped with a platform, it interfaces with materials using rollers, belts, or other methods.
  4. Lifting type: The platform can automatically lift materials and operate in sync with the assembly line.
  5. Forklift type: It uses an open forklift for material handling.


  1. High degree of automation: Controlled by computers, electronic devices, magnetic induction sensors, laser reflectors, etc. When a workshop section requires auxiliary materials, the computer terminal receives input from the staff, sends the information to the central control room, and professional technicians send instructions to the AGV robot to deliver the materials to the designated location.
  2. Automated charging: When the AGV robot’s battery is running low, it sends a request to the system for charging (a predefined threshold set by technicians). Upon system approval, it automatically queues up for charging at the designated location. Additionally, the AGV robot’s battery has a long lifespan (over 2 years).
  1. Aesthetically pleasing, enhances visual appeal, thereby improving the company’s image.
  2. Convenient, reduces floor space; AGV robot carts in production workshops can shuttle back and forth between various workshops.

AGV Robot Guidance Methods:

  1. Electromagnetic guidance: Electromagnetic guidance is a relatively traditional method still used by many systems. It involves embedding metal wires on the AGV robot’s travel path and loading guidance frequencies on the wires. The AGV robot is guided by recognizing these frequencies. The main advantages include discreet wiring, resistance to pollution and damage, simple and reliable guidance principles, easy control and communication, no interference with sound and light, and lower manufacturing costs. Disadvantages include the complexity of wire installation, difficulty in changing and expanding paths, susceptibility to interference from ferromagnetic materials, and limitations on complex paths.
  2. Magnetic tape guidance: Similar to electromagnetic guidance, magnetic tape is used on the surface instead of buried metal wires underground. Guidance is achieved through magnetic induction signals. This method offers good flexibility for changing or expanding paths, easy installation of magnetic tape, but is susceptible to interference from nearby metal substances and mechanical damage to the tape. The reliability of guidance is significantly affected by external factors. Once an AGV robot starts a task, it can only move along a fixed magnetic tape and cannot change tasks.
  3. Magnetic card guidance: Magnetic card navigation divides the AGV robot’s travel area into several coordinate sub-regions using positioning blocks. Guidance is achieved through counting the sub-regions, typically with magnetic strip tag cards (dividing coordinate sub-regions, traveling to target stations).
  4. Laser guidance: Laser guidance involves installing precise laser reflectors around the AGV robot’s travel path. The AGV robot emits a laser beam through a laser scanner and collects the reflected beam from the reflectors to determine its current position and heading. Continuous trigonometric calculations guide the AGV robot.
  5. Color tape guidance: Painting or pasting color tapes on the AGV robot’s travel path enables guidance through simple processing of the camera-captured color tape image signals. Optical guidance is similar to magnetic tape guidance, with advantages of easy road surface installation, good flexibility, simple ground route setup, and low cost. Disadvantages include susceptibility to pollution and damage, high environmental requirements, lower reliability, and accuracy.
  6. Mobile phone remote control: Control the movement of the robot by downloading a mobile app.

AGV ROBOT’s Basic Applications

Manufacturing Industry SMT AGV Robots shine in manufacturing production lines, efficiently, accurately, and flexibly completing material handling tasks. Multiple SMT AGV Robots can form a flexible logistics handling system, with transport routes adjusted in real-time to align with production process changes, enabling a single production line to manufacture a dozen or more products, significantly enhancing production flexibility and competitiveness for enterprises. In 1974, Volvo Kalmar car assembly plant in Sweden adopted an automatic car assembly line using SMT AGV Robots as carriers to enhance transport system flexibility.

The assembly line, consisting of multiple SMT AGV Robots capable of carrying car bodies, reduced assembly time by 20%, decreased assembly failures by 39%, reduced investment payback time by 57%, and lowered labor by 5%. Currently, SMT AGV Robots are widely used in the manufacturing and assembly lines of major car manufacturers worldwide, such as General Motors, Toyota, Chrysler, and Volkswagen. In recent years, as a fundamental handling tool for Computer Integrated Manufacturing Systems (CIMS), the application of SMT AGV Robots has extended to various industries including mechanical processing, household appliance production, microelectronics manufacturing, and tobacco, making production and processing the most widely applied field for SMT AGV Robots.

SMT Factories, Post Offices, Libraries, Port Terminals, and Airports In scenarios like SMT factories, post offices, libraries, port terminals, and airports, where there are significant variations in workload, high dynamics, frequent process adjustments, and a single handling process, SMT AGV Robots’ parallel operation, automation, intelligence, and flexibility characteristics effectively meet the handling requirements of these environments. Sweden started using SMT AGV Robots at the Stockholm post office in 1983, Japan at the Tama post office in 1988, and China at the Shanghai postal hub in 1990 to handle mail items. In the port of Rotterdam, the Netherlands, 50 SMT AGV Robots known as “yard tractors” handle repetitive tasks of transporting containers from the ship to warehouses several hundred yards away.

Tobacco, Pharmaceuticals, Food, Chemicals Industries like tobacco, pharmaceuticals, food, and chemicals, which have special requirements for clean, safe, and emission-free handling operations, also prioritize the application of SMT AGV Robots.
