I use cpp to imitate python script(move_robot.py). message md5sum is mismatch. about panda_simulator

You shouldn't have to copy the msg directories to your package. You should be able to use them directly in your package just by adding them as dependencies in your build configuration files. I believe the mismatch in the signatures could be because there are multiple instances of the same message files in your workspace.
Also, I will not be able to help you with building a different ROS package, sorry; please use other sources for figuring out these issues.
Closing this issue as it is not related to running or using this package. Please feel free to re-open if you think this wrong.

I checked. the original md5 of _RobotState.py(franka_ros_interface) is same with mine. which it means the msg generation is fine.
not multiple instances issue.
I guess there are some issue on my code. topic string I guess.
