自動導引車 (AGV)
& Autonomous Mobile Robots (AMRs)

RLS is a leading manufacturer and supplier of magnetic encoders for the AGV & AMR industry. With a wide range of design variants, industry standard output options, RLS encoders offer easy installation and reliable operation for years.

In logistic AGV/AMR sector, magnetic encoders provide excellent position feedback. Due to their non-contact operation they are extremely reliable and thanks to IP68 protection they can also be used in dusty environments.

AGV- automated guided vehicle is a portable robot that follows along marked long lines or wires on the floor, or uses radio waves, vision cameras, magnets, or lasers for navigation.

AMR - Autonomous Mobile Robot is a robot (vehicle) that uses on-board sensors and processors to autonomously move materials without the need for physical guides or markers.

AGVs & AMRs are used for moving large quantities of material repeatedly in a variety of applications in the automotive industry, logistics, smart warehouses, food and beverage, pharmaceutical and printing industries. They are designed to work in narrow aisles, reach high shelves and increase warehouse storage capacity. AGV/AMR bring considerable added value and enable flexible logistics for companies in all sectors, especially in these times when logistical bottlenecks are increasing.

AGV 的挑戰

0.50.5° 的精度

In order for the AGV/AMR to be able to determine the exact position of the wheel an encoder has to give accurate position. To control speed and direction, encoders are critical to ensure precise and safe operation.

小巧的設計與簡易的安裝

The encoders need to be compact. Many AGV / AMRs are compactly designed to meet the requirements of smart warehousing. Easy installation in the drive system is also an advantage.

抗衝擊與振動

When AGV or AMR operate in the plant or warehouse, they inevitably cause certain shocks and impacts due to uneven floors and messy objects. Therefore, the selected encoder must be highly resistant to shock and vibration to maintain its accuracy in the complicated environment.

運作原理

AGV & AMR drive units typically consist of a servo motor, a speed reducer, brake and tires and require an encoder to control the movement, steering and stopping of the vehicle. In speed monitoring, especially in combination with safety laser scanners for safeguarding danger points, the encoders are an essential component of a vehicle with a safety function.

AGV 的每個車軸/車輪因兩個馬達的扭矩差而繞著軸線轉向。每個車軸的驅動產生的角度位置回饋則實現了閉合迴路控制。
