Remote Motion Interface

In this video, we’ll take a closer look at FANUC’s Remote Motion Interface (RMI), a powerful software option designed to enable remote control of industrial robots. As automation applications increasingly require dynamic, runtime path generation, RMI offers a flexible and reliable solution for integrating external control systems with FANUC robots.

We’ll walk through how RMI works, what it’s capable of, and how it fits into broader automation strategies. You’ll see how RMI uses JSON packets to communicate motion and non-motion instructions from an external device, typically a PC directly to the robot’s teach pendant program. This approach allows for precise control while leveraging FANUC’s built-in motion planning capabilities.

What you’ll learn in this video:

• How RMI integrates with FANUC robots using JSON-based communication
• The structure and purpose of:
  • Communication packets (Connect/Disconnect)
  • Command packets (I/O control, frame data, robot status)
  • Instruction packets (motion commands)
• How RMI maintains compatibility with other FANUC software options like Collision Guard and DCS
• The role of Sequence IDs in managing instruction order and avoiding faults

Key requirements and considerations:

• RMI requires a client application capable of sending properly formatted JSON packets
• For advanced I/O or data handling, pairing RMI with the HMI Device option is recommended
• ASCII String Instruction mode is available for extended functionality beyond standard RMI commands
• Conditional and branching logic must be handled by the external control system

Whether you're developing a custom automation solution or integrating FANUC robots into a larger control architecture, this video will help you understand how RMI can streamline your process and enhance performance. If you're ready to explore remote motion control with FANUC, this is a great place to start.
