Given a stream of CAN bus messages represented as strings (e.g., 'TIMESTAMP ID PAYLOAD'), write a function to parse the stream, aggregate the payload values by ID, and return the moving average of the last N payloads for a specific ID.

Write an algorithm to navigate a factory Automated Guided Vehicle (AGV) from a starting point to a destination on a 2D grid representing the Gigafactory floor. The grid contains obstacles (machinery) and dynamic barriers (moving workers). Implement A* or Dijkstra's and explain how you would adapt it for dynamic obstacles.
