Iranian Lab's Quadcopters To Rescue Swimmers
mpthompson writes "Via RoboticsTrends' newsletter, RTS Lab in Tehran is developing Pars, which is an aerial rescue robot quadcopter designed to save potential drowning victims. The ship-based quadcopter responds instantly when alerted to potential victims in the ocean, locating them with thermal imaging sensors, and dispensing life preservers directly over them. The current prototype carries one life preserver, but they are working on a new model to carry three life preserver rings. Future models may dispense up to 15 self-inflating rings. A launching platform for use on ships has been designed, but more intriguing is an idea for a remote stand-alone launching platform. It's good to see innovative robot tech coming from a country that is not normally well covered in Western media."
I expect that's the main thing taking into consideration the mountain stealth jet.
*DRONES No more /. before coffee :(
It won't work worth spit in a storm.
and that is when you REALLY need something to work.
I wonder how the warmongers are going to spin this as evidence of nuclear weapons manufactory. Possibly as a delivery system for tactical nukes?

More likely a delivery system for thermite grenades over oil tankers.
Just some facts.
The range of these battery powered drones with pay-load(1.5kg) would be around 8 minutes, regardless of battery size.
Bigger battery = heavier = more power needed to move around and stay airborne
4 minutes out @ 20mph (unlikely in real world conditions) is 1.3 miles or 2.1 km.
30 minutes to recharge (assuming the wireless charging works at top speed)
For every 1.3 miles or 2.1 km of coastline you would need around 4 drones for 100% coverage.
And they will not work when winds are over 20 mph.
And they will not work in freezing conditions (batteries cannot deliver the power below 5 deg C).
Nice toys, no game changers.
I'm betting on their petrol powered 30 pound / 10 pound payload brothers.
Repeating that 1991 strategy as needed in Iraq and Afghanistan would have been far less expensive
Repeating 1991 would've given Saddam an excuse to murder another quarter of a million people as payback (which he did in the mid-90s). And the Arab Spring would never have happened if dictators were free to slaughter people at will.
I'm sure you were scared for your privacy when Bush passed the Patriot Act...
Yep, Obama started the Gulf War and Iraq War. That is why your comment makes so much sense.
while(1) attack(People.Sandy);
Even the variable pitch rotors used in full sized helicopters are not all that efficient compared to fixed wing aircraft. (Here "efficiency" is defined by the energy used to move payload). You see the fixed wing aircraft produce enough thrust to overcome drag and the aerodynamics of pushing the wing into air creates lift. Anything that hovers must produce enough thrust to overcome the weight. Typically in a fixed wing aircraft the Lift (or weight) to drag ratio is above 10. Thus you are using much smaller engine for the same weight in fixed wing aircraft. So purely by fuel efficiency point of view, rotary wing aircraft can never compete with fixed wing aircraft.
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
This actually sounds like a good idea. Perhaps they got tired of the US having to rescue their sailors?
I'm not really scared for my privacy at all, whoever is wiretapping me has the most boring job ever. I am active on RCGroups, somewhat active here, and spend a lot of time looking at tower hobbies, xheli, nitroplanes, banggood, and tmart. I call and text my parents, my fiancee, and various people from work. I almost exclusively email people from work, and I travel to and from Syracuse as needed for medical treatment for my son. Hopefully I just saved the FBI some time and resources. There's little they couldn't just find on my Facebook if they wanted to know any of that. I understand why other would be concerned about privacy but I quite simply couldn't care less. I don't believe government invading my privacy has made me safer or anything, but it truly has no effect on my life.
I offer a challenge: fly a fixed wing aircraft to a man in water. Stop the plane, throw down life preservers, and stay exactly above the swimmer with a beacon light to guide rescue swimmers in. I bet at the beginning of the second sentence fuel efficiency stops mattering as you fall out of the sky and the quad copter begins laughing maniacally. Rotary wing aircraft exist, and are used because despite the small disadvantages they also offer one huge advantage as well. There is a reason rotary wing is used over fixed wing in rescue operations, and it isn't because they forgot to ask your opinion.
Step 1) Google warthox. Step 2) Watch videos Step 3) Stand (or sit, I don't care) corrected. I can hit almost 20 mph with my $40 Chinese micro quad, hitting 50 is relatively trivial for a more expensive/powerful machine. Efficiency begins to matter less when you are trying to potentially save a life, especially when your aircraft is unmanned and expendable.
Imagine someone doing a long distance swim, say crossing the English Channel. This thing finds them and keep dropping life rings on their head.
Go imagine Natalie Portman swimming in a pool.
You'll have a nicer day.
Faster! Faster! Faster would be better!

No, no no. It's true Iran is making highly enriched Uranium that it could turned into weapons grade stuff in a couple of months, and is testing space launch systems that could easily be used as ICBMs and now is building naval drones that could be used to attack US ships.
But everyone knows these projects are all civilian. The Uranium is for a research reactor which they need to generate power. Even though most countries with large amounts of nuclear power plants don't have research reactors or local enrichment.
The rockets are so Iran can go into the space launch business because obviously US and EU companies would have no legal problems shipping satellites to a company in Iran run by the Revolutionary Guards.
And the drone is to rescue swimmers who've got into trouble. Even though the IRGC is not known for its concern about swimmers in peril
And if you believe all that, I've got a bridge to sell you.

I work in the robotics industry and what really caught my eye was that this interesting work is coming out of Iran. Something I thought was pretty cool considering the negative press we get from our media about the country. Obviously, the Iranian government is very anti-American, but I would bet if I were to sit down with the folks at JST Labs working on this project I would find we share a lot of common interests in technology and such. It is from such common interests that broader cultural bridges can be built from.
You appear to be picking a nit which wasn't offered.
Let's name other things that could deliver bombs: RC cars, normal cars, those little foam gliders you get from the dollar store, a Frisbee, and tennis balls. So what point were you trying to make?
As I said. A nit which wasn't offered. GPP mentioned the efficiency but in no way suggested that made them unfit for the job at hand. The only person running with that claim is you.
Sorry, I am a bit confused. Isn't this discussion about quadcopters in general and their rescue role in specific? Why would the GP mention fixed wing, unless he thought them to be relevant to the discussion?
For example, if you were discussing the merits of presidential democracy versus parliamentary democracy, and I jumped in to say that in Mussolini's fascist state, the trains always ran on time, would it not be proper for you to assume that i brought in fascism because i thought it had advantages over democracy? In which case, it would be perfectly fair for you to point out that if I had spoken out of turn in his regime, I would have been thrown straight under one of those efficiently running trains.
Would it then make sense for someone else to pop up and say that my facism remark did not deserve your response because I was not making any comparison with democracy?
A crank is a little thing that makes revolutions
He was responding to someone talking about the efficiency of non-pitch-shifting rotors. He commented on how efficiency doesn't improve much once you introduce blade pitch-control. He used fixed-wing aircraft as a contrast.
That's all.
You were the one who chose this subthread as your Nteenth location for saying the same thing, ignoring relevance to the specific discussion at hand.
Sure this overall story is about QCs and rescue. But the subthread you chose to lose your mind in isn't.
How about delivery systems? They are a bit noisy, but useful. All this crap about nuclear bombs was a mis-direct. Iran's goal is to compete with the likes of Fed-X, UPS, On-Trac, and the Post Office. This would make a good app, wait! Isn't there one of those already?
If deadmanwalking != skitchen8 I apologize, but the verbiage smells the same.
