HI, I am trying to make JACKAL follow a trajectory i.e set of coordinates but I am trying to track the location with an overhead camera. I initially looked at the movebase tutorial. I found out that, it uses the /odometry/filtered + other sensor data for localization and then publishes on cmdvel. I made changes to the robotlocalization package and stopped the ekflocalizationnode to stop publishing on /odometry/filtered and tried publishing on /odometery/filtered on a node that I created (with camera data)so that movebase can get data from my /odometey/filtered topic. It does not work. I am not looking for anything fancy or robust. No collision or obstacle detection is required

Can someone please guide me what to do here. I am really stuck here.

I am using ROS-Kinetic and writing code in ROSPY
