DJI Agras T50, agriculture drone

Appears to be priced around 12.000 USD. Scary. And it has phased array radars.

I fully believe in systems like this.

But they're going to need pretty advanced many-flight mission planning capabilities to really work. And they're going to need to be incredibly resilient/repairable.

Why? Well, look at the stats, you do the math:

> 50 kg spreading. Spreading 108 kg/min.

Yeah maybe it's not spreading/spraying at full tilt all the time. But it probably does need to be able to make dozens or hundreds of trips & refills a day to be of service on a real farm.
