Hi, I have an arm and a hand publishing different joint_states messages and I'd like to merge them (having seen this discussion: http://ros-users.122217.n3.nabble.com/robot-state-publisher-with-joint-states-in-different-messages-does-not-compute-tf-for-all-joints-td1945465.html ) Is there an existing node to merge the joint_states messages, or do I need to implement mine?
