This is not valid according to the URDF spec. Every link you refer to from a joint needs to be explicitly defined in the robot description. To fix this problem you can either remove this joint [sonar_front_joint] from your urdf file, or add "<link name="base_footprint"/>" to your urdf file. [robot_state_publisher-3] process has died [pid 4060, exit code 255, cmd /opt/ros/kinetic/lib/robot_state_publisher/state_publisher __name:=robot_state_publisher __log:=/home/lekhasree/.ros/log/09d44e52-da65-11ea-afc1-e8d0fc91b2fd/robot_state_publisher-3.log]. log file: /home/lekhasree/.ros/log/09d44e52-da65-11ea-afc1-e8d0fc91b2fd/robot_state_publisher-3*.log

Its hard to read can you properly format your question. May be attach all of your URDF, select all URDF code and press Ctrl + k.
