## gazebo_msgs

```
* Fix repo names in package.xml's

```

## gazebo_plugins

```
* Fix build with gazebo4 and indigo
* gazebo_ros_diff_drive gazebo_ros_tricycle_drive encoderSource option names updated
* gazebo_ros_diff_drive is now able to use the wheels rotation of the optometry or the gazebo ground truth based on the 'odometrySource' parameter
* simple linear controller for the tricycle_drive added
* second robot for testing in tricycle_drive_scenario.launch added
* BDS licenses header fixed and tricycle drive plugin added
* Fix repo names in package.xml's
* ros diff drive supports now an acceleration limit
* Pioneer model: Diff_drive torque reduced
* GPU Laser test example added
* fixed gpu_laser to work with workspaces
* Merge pull request #139 <https://github.com/ros-simulation/gazebo_ros_pkgs/issues/139> from jbohren-forks/hand-of-god
  Adding hand-of-god plugin
* HoG: adding install target
* hand_of_god: Adding hand-of-god plugin
  ros_force: Fixing error messages to refer to the right plugin
* Remove unneeded dependency on pcl_ros
  pcl_ros hasn't been released yet into indigo. I asked @wjwwood about
  its status, and he pointed out that our dependency on pcl_ros
  probably isn't necessary. Lo and behold, we removed it from the
  header files, package.xml and CMakeLists.txt and gazebo_plugins
  still compiles.
* minor fixes on relative paths in xacro for pioneer robot
* gazebo test model pionneer 3dx updated with xacro path variables
* pioneer model update for the multi_robot_scenario
* fixed camera to work with workspaces
* fixed links related to changed name
* diff drive name changed to multi robot scenario
* working camera added
* fix in pioneer xacro model for diff_drive
* Laser colour in rviz changed
* A test model for the ros_diff_drive ros_laser and joint_state_publisher added
* the ros_laser checkes now for the model name and adds it als prefix
* joint velocity fixed using radius instead of diameter
* ROS_INFO on laser plugin added to see if it starts
* gazebo_ros_diff_drive was enhanced to publish the wheels tf or the wheels joint state depending on two additinal xml options <publishWheelTF> <publishWheelJointState>
* Gazebo ROS joint state publisher added
