gpu_laser_ros_plugin

This is the ROS plugin for gpu_laser sensor

Steps to use this plugin:

1. Clone common_msgs for melodic and compile it using the command

catkin_make --only-pkg-with-deps common_msgs

2. source devel/setup.bash
3. Compile the gazebo_laser_plugin package using the command,

catkin_make --only-pkg-with-deps gazebo_laser_plugin

4. source devel/setup.bash
5. Launch the launch file using the command,

roslaunch gazebo_laser_plugin launch_gpu_ros.launch

6. After Step 5, we can see gazebo is up with the laser and few obstacles(but cannot see the laser signals yet though, need to check)
7. Launch RViz in another terminal using the command,

cd <path_to_gpu_laser_plugin_ws>
source devel/setup.bash
rviz

8. Add the laser_scan topic and change the frame to world or laser_sensor on RViz. You can now see the laser scans on RViz
9. We can also get the laser scan data using

rostopic echo /laser_scan
