Tutorials, guides, and updates on ROS2, intelligent agents, and the Nodeably platform.
Most ROS2 teams start in Python. The API is cleaner. Iteration is faster. rclpy handles the majority of nodes without issue. Then at some point a timer fires late, a high-frequency publisher drops mes
ROS2 is Linux-native. That is not a complaint about the design choice — Linux is the right foundation for production robotics. The complaint is about what the development toolchain assumes: that every
Your publisher is running. `ros2 topic echo` shows data flowing out. Your subscriber node is alive. The callback never fires. No error in the log. No warning on the console. Nothing. This is a QoS mis
A developer on Reddit described migrating a real project from ROS1 to ROS2. The launch file went from 10 lines to 50. Same nodes. Same topics. Same robot. That is a real measurement from a real migrat
You set up ROS2 on a laptop, connect to the office WiFi, and run a demo. The demo works. What you do not see is that every ROS2 node on your machine is broadcasting multicast discovery packets across
You run `colcon build`. It finishes. Exit code 0. You source the workspace, run your launch file, and get `package 'my_package' not found`. You build again. Same result. The build says it worked. The
You add a synchronous service call inside a timer callback. The code compiles. The node launches. Everything looks fine — until it doesn't. The node freezes, no error is thrown, and `ros2 node list` s
The code compiled. The node launched. The robot didn't move. I stared at the executor pattern Cursor had generated for ten minutes before realizing it was wrong in a way that no error message was ever
