Here is the rosgraph of the ros nodes i am running in my system. Here the rviz node is in my local linux computer and other nodes like move base, cv_camera, base controller are running in raspberry pi 4. image description Here as i saw multiple nodes are publishing the tf node. Problem i'm getting is that, the robot is not positioned in one place + map is changing its position. Here is the roswtf output:
