External Motion Control Using Dynamic Path Modification

In this video, we’ll explore Dynamic Path Modification, or DPM, a powerful motion control option available for FANUC industrial robots. Whether you're working in automotive, general industry, or developing advanced automation, DPM offers a flexible way to adapt robot paths in real time based on sensor feedback or external motion planning.

We’ll start by looking at how DPM was originally developed to track seams and surfaces, and how it has evolved to support dynamic, runtime path adjustments. This is especially useful in applications where parts vary or where motion needs to be controlled remotely.

Throughout the video, we’ll walk through:

• What DPM is and how it works
• How offsets are applied in real time in Cartesian space
• The different input types for DPM, including GROUP and DATAID
• Why Stationary Track is essential for external motion control with DPM
• How to tune DPM for smooth and responsive motion
• Best practices for logging and filtering offset data

You’ll also learn how DPM integrates with external motion controllers, how to configure input scaling, and how to use features like HSPO and Group Outputs to keep your system in sync. We’ll cover the pros and cons of each input method and explain why GROUP input is often the preferred choice for high speed, consistent updates.

If you're looking to implement real time path adjustments or improve your robot’s ability to respond to changing conditions, this video will give you a solid foundation. Sign in to watch and learn how DPM can elevate your automation strategy.
