ROS_Control is a set of packages that includes controller interface, controller manager, transmissions, hardware interfaces and control toolbox. ros_control will take the joint state data and an input set point (goal) as input from user/3rd party application as shown in Fig 3 and sends the appropriate. For example, a sensor driver will publish a message containing a camera image, then a node will receive a message, detect the people in it, and send another message with their positions. Another node will receive the positions message and calculate a desired action, and send that as a message. Benefits of managed lifecycle – Clear separation of real-time code path – Greater.
