ros2_control cannot load the specified hardware interface plugin. URDF ros2_control tag or plugin name is wrong.

generic

90% success Verify the hardware plugin name in URDF matches the installed plugin class
```
ros2 control list_hardware_interfaces  # after controller_manager is up
```

88% success Install the correct ros2_control hardware package

sudo apt install ros-humble-ros2-control ros-humble-ros2-controllers

85% success Check URDF <ros2_control> tag has correct plugin attribute
```
grep -A5 'ros2_control' my_robot.urdf.xacro
```

Common approaches that don't work:

Bypass ros2_control and publish joint states directly 85% fail
Loses hardware abstraction, safety limits, and real-time guarantees
Copy a hardware interface .so from another workspace 80% fail
Binary incompatibility between different colcon workspaces causes segfaults
