Problems visualizing robotmodel and tf's of urdf model in rviz [closed]

edit

Hi! I have build my own robot on sketchup, created an urdf file for it with plugins for the laser (libgazebo_ros_laser.so) and for the odometry (libgazebo_ros_p3d.so) and i'm simulating an navigation with it in gazebo. Until here it's almost 100% correct...

I run rviz to visualize what is happening with the sensors, tf's, etc... I just run rviz in command line and then i add what i need in the left bar (tf's, LaserScan, RobotModel and map).

Problems:

1 - i can't see correctly the tf's of my robot that are "continuous";

2 - i can't see the robot model

I think i' having this problem due to the type of the joints that are "continuous", but i have to use this for the odometry plugin for gazebo. Maybe is some problem on the joint_state_publisher, i don't know.

Do i have to create any kind of a launch file to launch rviz with joint_state_publisher too, just like for gazebo?

And why can't i see the RobotModel in rviz for my model, even if the joints are fixed? Maybe because it was designed in Sketchup?

Here is my model in urdf.
