There are definitely drones that can fly way faster than 30 knots, but they are not waterproof, and the ones I've seen are rather dumb, they don't follow you. Here's a drone that can fly at 100 mph (87 knots): https://www.youtube.com/watch?v=8p5uDf9i_Yc

Well, is not about the speed of the _drone_ but being able to fly in a 20knts wind, with 30, maybe more, gusts. Which means in order to keep course it needs to know the wind speed and compensate. It's been done ( for auto-boats ) but I doubt this drone has this. Last time on Hintertux at 3500m we had also strong winds while snowboarding. I'd give it a test nonetheless!

Right, but all wind is to a drone is a shifting reference frame. In order to stay still in a 20 knit wind, the drone would need to be able to have a top speed of, at least, 20 knots.

I probably have no clue what I am talking about, but wouldn't it be sorta like steering forces? Seek A Avoid B In your case, a ton of Bs in terms of leaves, branches and etc. I guess it would need a wide scan to detect if there is a path either vertically or horizontally.

Well, (A) has a tracking device. All the (B)s don't. If they did, then yeah, this would work. Right?

Yeah but I am thinking it has some sort of an scanner, sorta like self-parking cars do :).

So once it Avoids (Steers away) B it can continue to Seek (Steers toward) A with the tracking device.

Obviously depends on how well the scanner to pickup obstacles work. You would need some sort of a heat map to detect leaves or branches.

This is the big reason people don't buy these types of drones (this one certainly isn't the first of it's kind). It doesn't have obstacle avoidance or it will make a massive deal of it.

It is a hard robotics problem. Saying that "it would need a wide scan" is a vast underestimation. Try looking up some papers on obstacle avoidance. Also, consider the costs of sticking the additional sensors on the robot, processing that data in realtime, and still powering the whole thing.

Usain Bolt does around 38 km/h

Yeah, but I bet he accelerates faster. Edit: he accelerates from standstill at 9.5 m/s^2. I couldn't find data on what drones do.

Drones usually accelerate quite rapidly (electric motors and all).
