Key Engineering Takeaways
- •ros2_control abstracts physical hardware away from high-level software, enabling seamless switching between Gazebo simulation and real robot hardware.
- •Implement `read()` and `write()` methods inside your custom `SystemInterface` C++ plugin.
- •The Controller Manager runs at fixed deterministic frequencies (e.g., 100Hz).
Prerequisites
- • C++ pluginlib
- • URDF modeling
The ros2_control Architecture
Instead of writing custom ad-hoc driver nodes for every robot, ros2_control provides standard interfaces for position, velocity, and effort control across industrial arms, mobile bases, and quadrupeds.
