ROS joint_state_publisher

 This package contains a tool for setting and publishing joint state values for
 a given URDF. It publishes sensor_msgs/JointState messages for a robot. The
 package reads the robot_description parameter, finds all of the non-fixed
 joints and publishes a JointState message with all those joints defined.
 .
 It can be used in conjunction with the robot_state_publisher node to
 also publish transforms for all joint states.
