All jokes apart, here is the formal categorisation of drones by weight:

0-250gm - Nano drones
0.25-2 kg - micro drones
2 - 25 kg - Small
25 - 150 kg - Medium
>150 kg - Large

Solar powered mini drones are still some time away. Because the efficiency of solar cells hasn't reached a place where it can power the drones. Multi-rotors consume a very high amount of power. That is why the solar powered large aircraft was a fixed wing.

I might expect a hydrogen fuel cell powered drone to come in before a fully solar powered drone.

To be honest, there are a ton of low hanging fruits of good uses for nano-drones (and drones in general) before they start being used for violent purposes. To give a context, more % of cars have had accidents than % of drones being attempted for mischief.

Haha... the company name "Drona" actually refers to the Indian mythological teacher Dronacharya who was among the best archery teachers in the world. It stuck well because of its proximity to the drone word.

But I promise you, I won't bring in terminators and definitely won't send them back in time.

Well, it is not. We are open sourcing almost everything (designs, firmware, SDK, learning content etc.) that we are creating. We hope you build some cool drone apps sitting in your garages and showcase to the world.
