I am building a four wheeled mecanum robot with ROS interface. In order to do the simulation I used gazebo and the I used planar plugin to provide the inverse kinematics to the wheels. But, when I publish the velocity commands to the robot, I found that only the robot is moving without rotating the wheels. It seems that the the base of the the robot just slides without rotating the wheels.I am using gazebo version 9

Is there any solutions to fix it...
