Engineering a UAV avalanche rescue drone | Engineering a UAV drone swarm #13 & #14

In this video I am telling you guys what the focus will be for our UAV project and how we will do this. We are going to be saving people under avalanches, and we want to help avalanche rescuers and save the lives of skiers with an emergency beacon.

Sounds like radio transmitters wouldn't have a long enough range to accomplish this unless you plan on being close by.

I've worked with ground penetrating radar for civil engineering applications as well as mounted from a hexacopter drone when I used to work at a remote sensing research group. Shoot me a message if you want to chat more

Hey, I would love to know more about this! Thank you for the offer, do you have discord? My username is siep1 feel free to add me on there and let me know which username to accept :)

5:55 You do not necessarily need 3 drones to triangulate the position! I am an aerospace student more from modelling and simulation, GNC, sensor fusion side. We had an assignment where (in a MATLAB) simulation we had to implement a Kalman filter. The scenario was that there was a jammer somewhere in the area. You had a drone which was flying around. Your job was to estimate the position of the signal based on the signal strength. So how do You do that with just one drone? Well you obviously can't triangulate the position with one reading... But You do know the position of the drone. You also know the time of the reading... So just take 3 readings with one drone at 3 different positions and points in time and you could potentially triangulate. Actually our assignment approach was to do that with only one reading at a time with initial reading at the start of the simulation. Then use signal strength ratio between the initial signal strength and current signal strength to allow the Kalman Filters or Particle FIlters to find the position of the jammer.

Some more design criteria for drones in mountains: - very high wind resistance (the wind in the mountains is higher) - high agility and low flying speed (the terrain can be very inhomogeneous and therefore maneuvers are necessary) - high power / endurance (depending on the flight height and temperature, battery estimates and power requirements from the lowland do not apply) - full autonomy / mobile network datacomunication / drone swarm with mesh/relay capability (you will not have line of sight in the mountains, and none of the radio signals will penetrate mountains) You'll figure out the rest. PS (Ground penetrating Radar will not work) Best of Luck Z

Some good considerations especially the communication is something I overlooked, thanks! Also, how come penetrating radar won’t work?

[@bonuspaterfamilias]

Exciting progress! How about combining the avalanche transponder/reciever with a wifi/bluetooth sniffer? Almost every person carries a cellphone. A WIFI/BT sniffer picks up if there is a cellphone in the area (distance is relative, but it should work in a distance of 100m at least) I dont know how much deep snow blocks the signal. But it might work. Keep up the great work!

[@NaeviusUAV]

Certainly a good idea! I’ve thought of this for the search and rescue drone as well but I find it hard to imagine nobody tried this already. The only issue I can come up with is that 2.4 ghz is less good at penetrating terrain, I think? I will consider it!

Funny thing, as I previously told you, most fields that have simple requirements for remote checkups already use drones. Simple off the shelf systems absolutely fill most niches already. Period. Notice how you chose yet another field where you did not consult any experts? The responsibility of first responders is primarily to get to the incident area and then coordinate the search and, you know, navigate a damn incident area with multiple hidden lethal dangers. No one has time to mess around with a drone in those cases. Also those locator things are directional, so you're not going off signal strength, you're literally seeing the direction your signal is coming from. And that doesn't even consider that once found you still need to actually rescue folks... So, even one guy messing around with a drone instead of moving is literally one less life saver. And don't even get me started on rescue robots. That's a literal field of competition. Forget about competitors, there's actual damn competitions and only recently have some few examples shown any kind of usefulness in super specialized scenarios. *EDIT* Your combination of absolute lack of knowledge but deep conviction is actually quite insulting to the people doing this work. I personally know a lot of rescue workers, I actually make software for them as my job. Most of them would either ignore you or outright laugh you out the room.

Hey Argosh, I guess. Constructive help is always more difficult to give. However, it's also a lot more valuable. If you're not part of the solution, you're part of the problem, let that sink in. So, if you can't offer something helpful, maybe stay out of the way? While it's true that simple off-the-shelf systems fill many niches for remote checkups, not all fields are the same. First responders indeed have the primary responsibility to navigate dangerous incident areas, but this doesn't mean drones or other technology can't assist in making their job safer and more efficient. For example, drones can be used to quickly assess hazardous areas without putting personnel at risk, potentially speeding up the coordination process. The argument that locator devices are directional and not based on signal strength is somewhat valid, but integrating drones with these devices can help pinpoint locations more accurately from a safe distance before sending in personnel. Regarding rescue robots, while they are still developing and highly specialized, dismissing their potential outright ignores the advancements being made. Competitions drive innovation, and it's only a matter of time before these technologies become more practical and widespread. I’m sure there was a time when people thought the car wouldn’t replace the horse. Your tone and approach are not helpful. It's important to respect different perspectives and contributions, especially when they aim to improve challenging situations. Knowing rescue workers and making software for them is valuable, but it doesn't mean new ideas should be dismissed without consideration. Mistakes enable learning, and it's through our errors that we often gain the most valuable insights. When we make a mistake, we're allowed to understand what went wrong and how we can improve. This process of trial and error is essential for growth and innovation. By embracing our mistakes and analysing them, we can develop better strategies, refine our skills, and ultimately achieve greater success. I believe this is also known as gaining real-world experience. Keep up the hard work team Naevius & Josh!

@@BuildYourOwnDrone "before sending in personnel" tell me you know nothing about rescue work without telling me you know nothing about rescue work... I'd accept the criticism, if this was the first time. But continuously changing the label on the same idea everytime it turns out that anyone knowing the targetted field of the day will tell you it's a bad idea and not gonna work is more than silly. I have said time and again that due to the Invasion of Ukraine there was a massive rush in fields you haven't even heard of to check for applications with modern drones. It's a saturated market with even well funded established players struggling to stay in. Personal note: As both a volunteer rescue worker and someone in the business of making mission support software for them, it's kinda insulting to listen to this stuff. Try to assume the people doing the work are at least a little knowledgeable in related fields... There's a reason it's called "Mountain Engineering"...

Hey argosh! I don’t mean to insult any rescuers, and don’t happen to see attempting to help can be insulting. There are certainly things I am unaware of, and mistakes I’m going to make. But keep in mind that this is all shared on KZbin so others trying to enter this field can be aware of the challenges. Thank you for working with rescuers, and helping them out. Considering you know more about the process, I would love to have a call or chat with you to get to know more about the potential of our idea and understand which adjustments may have to be made. Side note, thank you buildyourdrone for backing me up. And argosh, please be aware you don’t know what people do, so I don’t know how you can say someone doesn’t know anything about something when you don’t know anything about what they know.
