Sure, break it into four parts: power, payload, routing AI, and compliance. First, nail the specs: solar panel area, battery capacity, max payload weight, flight speed, and endurance. Next, outline the AI: what data feeds (weather, traffic), algorithm type (A* with energy cost), and fail‑safe logic. Then list safety: obstacle detection, communication link, and legal altitude limits. Finally, map the prototype steps: build a mock‑up drone, run a simulation, test solar charge, tweak routing, and iterate. Let me know the numbers you’ve got and we’ll tighten the design.
