| 2016-02-22 10:57:51 -0500 | asked a question | Laser ray sensor not detecting object in plugin? Hi all, I’m new to Gazebo and I couldn’t find any examples that show the examination of a laser sensor data in a plugin. I’m using a model plugin and I inserted a box model in the gui. The visual ray shows the box stopping the ray. But, when I displayed the min, max range and the fidtance from a deted object. The distance from the object is always infinite. = 0.08 max_distance = 10 current_distance = inf The model.sdf is: <?xml version="1.0" ?>
