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.
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.
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.
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.
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.
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 の各ホイールは、2 個のモータのトルク差によって各軸周りに回転します。各軸の駆動系から角度位置に関するフィードバックを取得することで、クローズドループ制御が実現します。
