i am unable to use this gazebo plugin for differential drive it doesn't publish on the /odom topic and it doesn't subscribe to the /cmd_vel topic when i do rostopic list It must show /odom and /cmd_vel in the list but its not showing it have added this plugin in robot.urdf other plugins like imu,lidar are working i can see scan and imu in topic list but not this what could be the mistake ?
