Cue

polonius_msgs/Cue

This message not only represents a simple log message, but also can trigger Polonius to move from one state to another.

Interface Update

polonius_msgs/InterfaceUpdate

This message is sent from the Polonius engine to the GUI to communicate what elements of the graphical interface to display. It contains 4 main pieces of information.

• The name of the state
• A descriptive label for that state
• A status code (see below)
• List of button texts to display

Status Codes

The five status codes represent which state the Polonius engine is in.

1. Pausing - Waiting a set amount of time before proceeding to the next state
2. Waiting for Cue - Waiting for the initial click to enter a state
3. Executing - Status while an action is being executed
4. Waiting for Outcome - Waiting for the terminal click to transition out of a state
5. Done - Polonius has reached a terminal state and is finished executing
