Hello, thank you for your contribution. I encountered some problems when I reappeared your work recently, and I look forward to your reply.
First of all, in the dead_reckoning.py file, it seems that you don't have the initialization parameter self.rov_id, which makes it impossible to correctly publish the transformation from odom coordinate system to base_link coordinate system of each robot.

However, the launch file of each rov has the following definition: .
Why is it wrong to report "unknown frame world"? I would appreciate it if you could give me some advice.
