Key features and benefits
Cargo platform lifting—precise integration with "goods‑to‑person" systems
"Goods‑to‑person" is one of the most common application models for AMRs today—robots transport shelves or totes to picking workstations, where picking is performed by humans or robotic arms. AMRs require precise control over the lifting height of the cargo platform to achieve accurate alignment with conveyor lines, shelves, or workstations at varying heights. Our linear actuators provide precise stroke control and smooth lifting motion, ensuring the platform moves at a constant, stable speed without jerks during the lifting process. In AMR systems such as Scallog in France, linear actuators are used to lift shelves, with the system capable of delivering a powerful thrust of up to 15,000 N.
Top-mounted robotic arm drive—empowering AMRs with multifunctional capabilities
AMRs typically require robotic arms or other equipment mounted on top to perform various operational tasks. Our linear actuators drive the vertical movement of robotic arms along the Z‑axis, enabling the grasping, placement, and stacking of materials. The actuators provide reliable motion control and precise positioning, enabling the robotic arm on the AMR‘s top module to move and operate smoothly, thereby enhancing the AMR’s flexibility and versatility.
Ultra‑compact design, suited for AMR‘s limited space
AMRs must integrate multiple components—including batteries, drive units, navigation equipment, and control systems—leaving little room for lifting mechanisms. Our linear actuators are known for their compact and energy‑efficient design—with no hoses, pumps, compressors, or other components, they significantly save installation space. Their compact size allows them to be easily integrated between the AMR’s chassis and cargo platform, reliably performing lifting and handling tasks without interfering with the navigation system or battery layout.
Energy‑efficient and high‑performance, suitable for battery‑powered platforms
AMRs are typically battery‑powered and have extremely strict energy consumption requirements. Our linear actuators utilize a highly efficient electric solution that consumes power only during active operation and has extremely low power consumption in standby mode. Support for power supply voltages up to 48V ensures compatibility with AMR platforms operating at various voltage levels. These low‑energy consumption characteristics effectively extend the AMR‘s runtime per charge and enhance the equipment’s continuous operation capabilities.
Long service life and maintenance‑free operation ensure round‑the‑clock performance
AMRs often require round‑the‑clock, high‑intensity continuous operation. Our linear actuators feature a maintenance‑free design, eliminating the need for regular lubrication or replacement of wear‑prone parts. The actuator‘s service life is designed to match the lifecycle of other critical components, such as drive wheels and batteries. Extremely low maintenance requirements ensure uninterrupted year‑round operation of mobile robots.
Intelligent communication, integrated into the digital logistics ecosystem
Our linear actuators support standard industrial communication interfaces such as CANopen and IO‑Link. Through these intelligent interfaces, the actuators can transmit data—including position, speed, and status—in real time to the AMR’s main control system or upper‑level management system, enabling remote monitoring and diagnostics. This high level of digital integration transforms the AMR from a mere material‑handling device into a data node within intelligent logistics.
Built‑in Hall sensors enable precise control for customers
Our linear actuators feature built‑in Hall sensors that provide real‑time feedback on stroke position and operational status via pulse signals. Based on this data, the customer‘s control system can precisely monitor key parameters—such as the height of the cargo platform and the Z‑axis position of the robotic arm—to achieve precise closed‑loop control. The real‑time feedback from the Hall sensors provides an accurate basis for the AMR’s autonomous decision‑making—from the precise lifting of shelves to the precise placement of materials, every action is executed with precision under closed‑loop control.
Richmat‘s engineers provide end‑to‑end technical support—from needs assessment and solution design to product delivery—ensuring that every autonomous movement and every moment of intelligent logistics is supported by reliable linear drive systems.
