Admittedly a half baked idea, but I wish someone was attempting to design an ornithopter as an alternative to drones for things like short-distance deliveries.

Admittedly a half baked idea, but I wish someone was attempting to design an ornithopter as an alternative to drones for things like short-distance deliveries. Given higher power density batteries and advances in RL to find efficient flight control policies it seems plausibly possible, and it'd eliminate noise pollution concerns almost entirely. Plus, the mental image of a mechanical harpy eagle (payload capacity greater than body weight) perched on your window sill with your doordash is just too appealing to pass up.
