robot_protocol_msgs 0.7.10 robot_protocol_msgs is the second generation of the transform library, which lets the user keep track of multiple coordinate frames over time. robot_protocol_msgs maintains the relationship between coordinate frames in a tree structure buffered in time, and lets the user transform points, vectors, etc between any two coordinate frames at any desired point in time.
