What is an Automated Guided Vehicle (AGV)?

AGVs, or Automated Guided Vehicles, are autonomous mobile robots designed to transport materials, goods, and products within various environments, without the need for human intervention. These intelligent machines follow predetermined paths, interact with their surroundings, and execute tasks with precision.

AGVs serve a multitude of purposes across industries. Their primary functions include material transport, product handling, and workflow optimization. They are engineered to reduce human labor, improve efficiency, and ensure the seamless movement of goods in diverse settings.

How AGVs Work

AGVs operate using a combination of advanced technology and precision engineering. From navigation and steering to obstacle detection and fleet management, each system works together to ensure smooth and efficient material handling.

AGV Navigation Techniques

Path Decision: AGVs determine their routes using onboard sensors, programmed maps, and guidance inputs. Many AGVs operate on fixed paths using magnetic strips, floor-mounted QR codes, or painted lines. Others use dynamic path decision-making to avoid obstacles and reduce travel time. These decisions are typically made within structured environments designed for repeatable, high-accuracy movements.
AGV Steering Control: Steering systems help AGVs follow their designated routes accurately. Depending on the application, AGVs may use differential drive, rear-wheel steering, or omnidirectional wheels to maneuver through tight or complex areas. Accurate steering control improves safety and minimizes operational disruptions in narrow aisles or dense warehouse layouts.

Advanced Navigation Modes

Frequency Select Mode: In frequency select mode, each AGV follows a specific radio frequency or signal embedded in the floor. This prevents interference between multiple vehicles operating in the same space. It is ideal for operations with overlapping zones or where multiple routes are needed.
Path Select Mode: Path select mode allows AGVs to choose from multiple predefined routes based on current task requirements. This flexibility makes it easier to adjust workflows and redirect traffic without needing to change the entire infrastructure.
Magnetic Tape Mode: This navigation method uses magnetic tape adhered to the floor to guide the AGV. The vehicle’s sensors detect the magnetic field to stay on track. It is a cost-effective solution for environments with consistent, unchanging paths.

Traffic and Movement Optimization

Traffic Control: Traffic control systems manage AGV movements to prevent collisions and bottlenecks. Whether coordinated through a central controller or via AGV-to-AGV communication, these systems ensure smooth flow, especially at intersections or shared spaces.
Zone Control: Zone control divides the operational area into specific sections. AGVs are assigned access to these zones based on task priority or availability. This reduces congestion and improves safety by limiting how many AGVs can operate in a given area at once.

Obstacle Avoidance and Sensing

Forward Sensing Control: Forward sensing control enables AGVs to detect objects or people in their path using technologies such as LiDAR, infrared, or ultrasonic sensors. This helps prevent accidents and allows the AGV to stop or reroute as needed.
Combination Control: Combination control integrates multiple systems such as navigation, sensing, and steering to enhance overall performance. It allows AGVs to respond more intelligently to their environment and maintain operational efficiency in dynamic settings.

Fleet-Level Coordination

System Management: System management platforms oversee the performance of all AGVs in a facility. These systems handle job assignments, monitor battery status, schedule maintenance, and adjust routes in real time. Centralized management is essential for coordinating large fleets and minimizing downtime.

Battery Charging for AGVs

AGVs are powered by rechargeable batteries and are designed to recharge automatically. When battery levels drop, the AGV navigates to a charging station without operator input. Some systems also use opportunity charging, allowing AGVs to recharge during idle periods to stay operational throughout the day.

Types of AGVs

AGVs come in various shapes and sizes, each tailored to specific tasks. Let's explore some of the diverse types of AGVs:

Automated Guided Carts

These are small, compact AGVs designed for carrying lighter loads within confined spaces, such as hospitals and laboratories. They can also be utilized in warehouses to provide movement of larger SKU assortments throughout the warehouse.

Best for: Hospitals, laboratories, and warehouses with narrow aisles or frequent small-item movement.

Towing AGVs - Tuggers

Towing AGVs are ideal for pulling multiple carts or trailers, making them valuable for industries with frequent material transport needs. These are robust solutions that can handle larger loads and even be utilized for pallet movements.

Best for: Manufacturing plants and warehouses needing to move multiple loads on repetitive routes.

Unit Load Vehicles

Unit load AGVs are capable of handling large, uniform loads, making them a common sight in warehouses and manufacturing facilities.
