L300 AMR offers a flexible interface to integrate with various lift systems, further enhancing its adaptability within factory environments. One significant method involves employing an external I/O interface, which enables the AMR to interact with lift controls effectively. The AMR communicates with the DFleet server, which sets up the interaction with the lift system through a strong WiFi connection.

External I/O Interface:

A scenario of external I/O interface during an operation where the AMR needs to move from Level 1 to Level 2:

1. The AMR arrives at the lift door on Level 1, triggering a simulated button press for Level 1 while awaiting confirmation of the door’s opening status.
2. Upon verification, the AMR enters the lift on Level 1 while maintaining the simulated button press.
3. As the lift ascends, the AMR releases the simulated button press at Level 1 and triggers a button press for Level 2, awaiting the corresponding door open signal.
4. Upon reaching Level 2, the AMR exits the lift while still holding the simulated button press.
5. Subsequently, the AMR releases the simulated button press and proceeds with its designated operation.

Internal I/O Interface:

This method, a Programmable Logic Controller (PLC) or equivalent system is added depending on the Lift Controller interface type to facilitate communication between the AMR and the lift system. The internal I/O interface system serves to translate triggering signals from the DFleet server into commands compatible with the specific protocol of the lift controller. This interface system normally requires customization as the Lift Controller might require different interface protocol for the controls.

A scenario of internal I/O interface during an operation where the AMR needs to move from Level 1 to Level 2:

1. Upon reaching the lift door on Level 1, the AMR initiates a call signal to prompt the lift’s movement to Level 1, awaiting confirmation of the lift’s arrival and door open signal from the Lift Controller.
2. Once validated, the AMR enters the lift on Level 1 while maintaining the door open signal.
3. As the lift ascends, the AMR releases the door open signal at Level 1 and triggers a call signal for the lift to proceed to Level 2, again awaiting confirmation of arrival and door open signal from the Lift Controller.
4. Upon reaching Level 2, the AMR exits the lift while still holding the door open signal.
5. Subsequently, the AMR releases the door open signal, continuing with its designated operation.

Multi-level Map & Teleport

NavWiz supports multiple active maps, allowing separate setup and configuration for each floor. SK’s Teleport feature enables AMRs to “jump” between levels by switching maps. During path planning, the system automatically detects level changes, triggering the Teleport Task Template to handle all lift interfaces. This simplifies configuration and allows reuse across floors.

SK’s AMRs, with advanced communication and navigation, streamline material handling and enhance operational efficiency, demonstrating the impact of automation in modern factories.
