Incomplete turtlebot model on fuerte gazebo
I know questions like this have already come up (here and here). Since I am yet to get a clear solution, I am re-posting. I face the following problems:
Incomplete model of the TurtleBot.
From this, I found that by uncommenting a part of the code in turtlebot_body.urdf.xacro, one can see the complete model of the robot instead of just 2 wheels. After uncommenting the part, I was able to the complete model of the robot in the empty.world but in the world that I built. I am still seeing just two wheels in my world. Does this problem still persist? Is there a solution ?
RaySensor warning.
My gazebo shell in spammed with Warning [RaySensor.cc:206] ranges not constructed yet (zero sized)
when I spawn the TurtleBot. I searched for the file which has this line and comment it, but without any luck. Though this isn't a major issue, it still is irritating.
I am running ROS-Fuerte on Unbuntu 12.04.
Thanks,
Prasanna
P.S: I know this could be posted in gazebosim forum. I hope some ROS enthusiasts might help me here.
