URDF + RVIZ , RobotModel Not showing correctly
Hi, I am trying to simulate a car on RVIZ only using URDF and Launch file and seems to not be working. The wheels are in the middle of robot which makes no sense because when I view on on a URDF online view it displays it correctly. Been struggling for awhile now. Any help will be much appreciated. Thanks!

Launch File:
<launch>
<param name="robot_description" textfile="$(find ros_robotics)/urdf/lauroRobot.urdf" />
<node name="joint_state_publisher" pkg="joint_state_publisher" type="joint_state_publisher" />
<node name="robot_state_publisher" pkg="robot_state_publisher" type="state_publisher" />
<node name="rviz" pkg="rviz" type="rviz" required="true" />
</launch>
</robot>
Works fine on my computer (once I moved the end robot tag from the launch file to the urdf). Is there any terminal output?
were you able to solve your problem? how?
