/joint_states return inaccurate joints information about ros-gazebo-gym

Hey @YY-GX, thanks for reaching out with your question! The /joint_states topic originates from the franka_ros package. It might be helpful to verify if you're encountering similar issues when directly interacting with the robot through that package. For modifications related to position control in the set_joint_positions method, you can refer to this section of the code:

Unfortunately, I'm currently strapped for time and won't be able to dive deeper into debugging your issues. I hope the pointer above offers a good starting place for troubleshooting.
