Hi, I started to move our code for our robot kinematics to ROS. I would like to know what is the stabilization status of kinematics stack, because latst review happend nearly year ago. I have some remarks and suggestions about kinematics stack : - kinematics serwices use motion_planning_msgs/RobotState which contains alot of unnecessary data. - SolverInfo contains limits field which duplicate data avalible through robot_description. - pr2_kinematics contains many useful functions in pr2_arm_kinematics_utils.cpp this could be moved to common package, maybe kinematics_utils. - common node for ik and ik_with_constraints should exist, using kinematics plugins. This would simplify implementation of kinematics for new robot. Pozdrawiam Konrad Banachowicz
