[arm.world](/upfiles/14398153029914819.world)Hi everybody,
I'm building a simple arm robot. I built a world containing the ground, a sun and my arm. Then I simply launch the world using the command "gazebo arm.world" and let my arm robot fall down. But the several links of the robot don't collide. I put the tag "" to "true" in my arm model and I also tried to use a model\_plugin to programmatically set the "self\_collide" attribute for each link to "true".
Does anyone have an idea why there is no collision ? (I looked with the view->collision but nothing happens). Could it be because my links don't have any inertial properties ?
I just need the two fingers of the arm to collide together but have no idea how to process...
Cheers,
Debz
