Detailed Description

Gazebo Ros imu sensor plugin.

GazeboRosImuSensor is a plugin to simulate an Inertial Motion Unit sensor, the main differences from GazeboRosIMU are:

inheritance from SensorPlugin instead of ModelPlugin,
measurements are given by gazebo ImuSensor instead of being computed by the ros plugin,
gravity is included in inertial measurements.
