Revision history [back]

Hello,

I have a problem with gpu_ray sensor for ROS Indigo integration. Currently we have multiple PCs with the exact same Gazebo version 2.2.1. We have the same exact ROS Indigo. We have installed gazebo_ros_packages.

So, I have succesfully created a .xacro Pioneer robot model which has gpu_ray sensor, and all works well. But when I try the exact same model on another PC, the gpu_ray sensor somehow "does not" detect the maximum range of the sensor (I have tried debugging via RVIZ, the sensor only work on min_range).

Success in PC A:

Failure in PC B, C, etc

            </plugin>
        </sensor>
    </gazebo>

The error is: other PC seems can not "read" the maximum range. (The error also the same for RRBot example with gpu_ray sensor)

I am wondering if anyone has some solution regarding this glitch? Any tips and help is really appreciated, thanks before!
