Mission Planner

Vehicle dynamics during an autonomous mission is fully controlled by the mission planner, which directs task nodes, controls trajectory between tasks and manages time. The mission planner is written in Python and utilizes a finite state machine

The highly modular software architecture complements the functionality of the mission planner. The mission planner’s multi-threaded structure allows for simultaneous execution of mission tasks and watch states that serve to keep track of the mission and task statuses. It is coupled with extensions for execution and cleanup of arbitrary scripts on the fly. The mission planner also manages contingency states to allow for recovery via the saved waypoints during the mission run.

Mission runs can be dynamically built from user input, providing an option to test task nodes independently in addition to a full mission test. The vehicle status is consistently checked and an alert is sounded in the event of an irrecoverable component failure.
