Free Tool Lets Older FANUC Robots Run Modern Open-Source Software

If you run a factory or work with industrial robots, there's a frustrating problem: older robots often can't talk to modern software. That forces companies to buy expensive new robots just to use current tools. A new open-source project, fanucpy_ros2, cracks that open. It was built by an engineer who needed to connect an older FANUC M-10iA robot with the widely used ROS 2 software — and it works.

ROS 2 is like an operating system for robots. It helps different robot parts talk to each other and lets people write programs to control them. MoveIt 2, a toolkit built on top of it, plans safe movements. This new bridge lets an old controller, the R-30iA Mate, publish live robot status, accept motion commands, run grippers, and even visualize the robot in RViz2. The developer used a Python library called fanucpy to talk to the controller, then wrapped it in standard ROS 2 packages.

The practical benefit: you don't need to scrap a robot when its software gets old. The tool is free and open-source. It also includes safety features — all motion and write commands are disabled by default, and requests are checked against limits. The developer tested it with a real physical robot.

The catch: it's community-made, not an official FANUC product. It was tested on only one controller software version, so your mileage may vary. You'll need some technical skill to get it running. But for a small business looking to extend the life of an older robot, this could save thousands of dollars.
