Autonomous Mobile Robots (AMRs) and Automated Guided Vehicles (AGVs) are both kinds of robots that help move materials from one spot to another efficiently and safely, moving around people and obstacles in factories, distribution centers, and warehouses. These robots help reduce mistakes and improve the productivity of workers.
What is an AGV?
An Automated Guided Vehicle (AGV) is a programmed mobile robot in advanced that follows lines or wires on the floor, or navigates using radio waves, cameras, magnets, lasers. AGVs are typically used to automate workflows in industries where repetitive material handling tasks are required, improving efficiency and reducing the need for human labor in these tasks.
What is an AMR?
An Autonomous Mobile Robot (AMR) is a more advanced type of robot that can understand and navigate its environment without needing fixed paths. Unlike Automated Guided Vehicle (AGV) which follow marked routes.
AMRs use advanced sensors, cameras, and sometimes artificial intelligence to see their surroundings, make decisions, and move efficiently through different areas.
What Is The Difference Between AGV & ARM?
Navigation & Obstacle Avoidance
The main differences between an Autonomous Mobile Robot (AMR) and an Automated Guided Vehicle (AGV) are how they navigate and deal with obstacles.
Autonomous Mobile Robots have advanced sensors that help robots understand their environment and move around freely. AMRs can detect and avoid obstacles in their way and adapt to changes in new environments without needing lines on the floor or magnets to guide them.
On the other hand, Automated Guided Vehicles follow a fixed path. Older AGVs use wires under the ground or painted lines, while newer ones have sensors like AMRs. These sensors can help the AGVs recognize obstacles, but the AGVs can't change the new route by itself. If have an obstacle blocking the path, the AGV will stop and wait until the path is clear.
Safety
Both AMRs and AGVs come with safety features like emergency stop buttons, sensors, and cameras. However, AMRs are often considered safer because robots can move around people and obstacles on their own.
AGVs usually work in areas away from people to keep things safe. Normally, AGVs have to go a long way to get to the destination, which can cause more depreciation on the vehicle.
Ownership Cost
Owning Autonomous Mobile Robots generally costs less overtime compared to traditional Automated Guided Vehicles because AMRs are simpler to set up and maintain. Even though AMRs use more advanced technology, they are still cost-effective to deploy.
AGVs might be cheaper to purchase initially but can become more expensive in the long run. This is because the technology and infrastructure AGVs require, such as magnetic tapes or wires, are less costly upfront than the sophisticated sensors and software needed for AMRs. However, maintaining AGVs can be more difficult and expensive because the system relies on this dedicated infrastructure. Any needed changes or repairs can be costly and time-consuming.
Although AMRs have a higher initial cost due to their advanced navigation technologies, including high-end sensors, cameras, and sometimes artificial intelligence, they can save money over time. Their ability to adapt and scale easily means they can be more cost-effective in environments that change often, leading to lower overall costs.
Deployment
Deploying an Autonomous Mobile Robot is generally fast and causes minimal disruption, regardless of the deployment site's size or complexity. AMRs don't need special infrastructure or wiring, so they can be set up in various environments and start working immediately. They navigate around obstacles on their own, which eliminates the need for extensive programming or training.
In contrast, deploying traditional Automated Guided Vehicles often involves significant integration challenges. AGVs require specific infrastructure like wiring or magnetic tape for navigation and need precise programming to follow designated routes. Changes to facility layouts mean AGVs require a complete reconfiguration, whereas AMRs can simply be reprogrammed to adapt to new routes or tasks.
Flexibility
AGVs typically perform a single task and may struggle with environmental changes, like new equipment in their path, due to their reliance on sensors and fixed paths. However, AMRs use advanced autonomous technology, allowing them to continue operating effectively even as their surroundings evolve. This makes AMRs much more flexible and adaptable than AGVs.
Maintenance
Traditional AGVs need regular maintenance checks to ensure their magnetic tapes are intact, as damage from frequent traffic, like people or forklifts, can stop them from moving. AMRs, on the other hand, require less infrastructure maintenance. Both types of robots need routine cleaning to remove dirt and dust from sensors and components, regular battery charging, and occasional software updates. Despite these maintenance needs, mobile robots offer significant benefits over traditional task execution methods.
AGV vs ARM: What Should I Choose?
Choosing between AGV and AMR depends on your specific operational requirements and goals. AGVs are well-suited for environments with fixed layouts and repetitive tasks, offering a cost-effective solution for operations that require reliability and simplicity.
Conversely, AMRs are ideal for dynamic settings where flexibility and adaptability are crucial, such as in e-commerce warehouses that experience frequent layout changes. AMRs also integrate easily with human workers, enhancing safety and collaboration on the floor. When deciding, consider factors like the nature of the tasks, budget constraints, layout variability, and interaction with human staff. Consulting with a specialist can also provide tailored insights to better inform your decision.

FAQs
What do AGV and AMR stand for?
AGV stands for Automated Guided Vehicle. AMR stands for Autonomous Mobile Robot.
What is the main difference between AGVs and AMRs?
AGVs follow fixed paths using physical markers like tapes or wires, making them ideal for stable, unchanging environments. AMRs use sensors and software to navigate dynamically, allowing them to operate flexibly in changing environments.
Which is more cost-effective: AGVs or AMRs?
AGVs generally have a lower initial cost but may incur higher long-term expenses due to infrastructure changes. AMRs, although more expensive initially, can be more cost-effective over time due to their flexibility and lower maintenance requirements.
Can AGVs and AMRs work together in the same environment?
Yes, AGVs and AMRs can be integrated within the same operation. The choice to use both depends on the specific needs of different areas within a facility, leveraging the strengths of each type of robot.
Are AGVs or AMRs better for working alongside humans?
AMRs are specifically designed to be safe and efficient in environments where they interact with humans. They can navigate around people and adapt to human movements, making them better suited for collaborative tasks.
How do AGVs and AMRs handle obstacles?
AGVs typically stop when they encounter an obstacle and require manual intervention. AMRs, on the other hand, can detect obstacles and find another route autonomously.
What are the maintenance requirements for AGVs and AMRs?
AGVs require regular maintenance of their physical guiding infrastructure. AMRs require less infrastructure maintenance but need regular updates and checks on their sensors and software systems.
