VisualStates

It represents visually the robot’s behavior as a graph on a canvas composed of states (nodes,vertices) and transitions (edges, links). When the automaton is in a certain state it will pass from one state to another depending on the conditions established in the transitions. This graphical representation allows a higher level of abstraction for the programmer. It combines a graphical language to specify the states and the transitions with a text language (Python) to detail the behavior on each state or the conditions in the transitions.

VisualStates generates a ROS node which implements the automata and shows a GUI at runtime with the active state every time, for debugging.
