Are there any motion planning stacks that support safety-rated operation for industrial robots?

Yes—there are a few, but with an important caveat:

Most motion planning stacks themselves are not safety-rated.
In industrial robotics, “safety-rated operation” usually means the safety function is certified as part of the robot controller, safety PLC, drives, and I/O chain, not just the planner software.

Commonly used options

1) Vendor robot ecosystems with certified safety functions

These are the most common way to get safety-rated operation:

• ABB (SafeMove)
• KUKA (SafeOperation / safety packages)
• FANUC (DCS: Dual Check Safety)
• Yaskawa / Motoman
• Universal Robots (built-in safety functions, though not “safety-rated motion planning” in the academic sense)

These systems support things like:

• Safe speed monitoring
• Safe zones / safe workspace limits
• Safe stop functions
• Safe reduced speed
• Safe directional or position supervision

They generally do not certify arbitrary external motion planners as safe. Instead, the planner sends targets, while the certified controller enforces the safety constraints.

2) ROS 2 / MoveIt 2 based systems

• MoveIt / MoveIt 2 are widely used for motion planning, but they are not safety-rated.
• They can be used in a system that has certified safety hardware, but the planning stack itself is not what provides the safety certification.

Typical architecture:

• Planner computes motion
• Safety PLC / robot controller enforces safety limits
• External safety sensors and certified stops handle hazardous situations

3) Safety-certified industrial controllers and PLCs

For applications that need certified behavior, people often combine:

• A motion planning stack
• A safety PLC such as Siemens, Pilz, Beckhoff safety systems, Rockwell GuardLogix, etc.
• A robot controller with certified safety functions

This can make the overall cell safety-rated, but not the planner alone.

If you mean “planner that is itself safety-certified”

That is much rarer. In practice, truly safety-certified motion planning algorithms/software are uncommon because certification is hard when the planner is dynamic, environment-dependent, and complex.

Bottom line

• Yes, industrial robot systems can support safety-rated operation
• No, most generic motion planning stacks are not themselves safety-rated
• Safety is usually provided by:
  • certified robot controller features
  • safety PLCs
  • safety-rated sensors
  • hardwired/validated safety architecture
