Precision in Motion: How RLS Magnetic Encoders Support AGV and AMR Operations

The Role of Magnetic Encoders in AGVs and AMRs

Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs) are transforming the industry by automating material transport with speed and precision. These robots play an important role in logistics, the automotive industry, the food and beverage industry and smart warehousing, where maximum efficiency and accuracy are essential.

AGVs use fixed paths controlled by technologies such as cameras, lasers or magnetic markers, while AMRs navigate autonomously with the help of onboard sensors and processors. Both systems are designed to optimize operations in dynamic environments, from navigating narrow aisles to increasing storage capacity.

At the heart of these systems are magnetic encoders, such as the RLC2IC and RM44, which provide vital position feedback for smooth and precise movement. RLS encoders are designed to meet the demands of industrial applications and provide reliable performance even in challenging conditions.

The Challenges of AGVs and AMRs

• Accuracy of 0.5°: Precise position feedback is essential for AGVs and AMRs to control speed, direction and positioning and to ensure safe and reliable operation.
• Compact Design and Easy Installation: Compact encoders are crucial for integration in tight spaces. Easy installation further enhances their suitability for modern AGV and AMR systems.
• Shock and Vibration Resistance: Operating on uneven floors and near obstacles requires encoders that can withstand shocks and vibrations while remaining accurate and reliable.

How Do They Work?

AGVs and AMRs rely on components such as servo motors, speed reducers, brakes and tires to function effectively. Encoders are key to controlling movement, steering and stopping.

In these systems, RLS encoders such as the RLC2IC and RM44 provide essential position feedback for closed-loop control, enabling precise navigation and efficient operation.
