Never thought I would even see the "Starwars Musquito Defense System" being actually developed :) https://www.youtube.com/watch?v=wSIWpFPkYrk

Ugh. The method I devised to get rid of these large black flies from indoors: Open a door and simply herd/walk them out by making yourself big. It's surprisingly easy - so much easier than trying to swat them. They seem to instinctively avoid things moving towards them, and because of that they're pretty easy to herd.
Relatedly - if you need to get a light-seeking insect (such as a moth) out of a room, you can just turn off all the lights and open the window. In general, people look at you like a wizard when you exploit the behavior of a creepy-crawly to get it to do what you want. For example you can catch a spider quite easily by placing a drinking glass in front of it and nudging its behind. It will panic-run forward into the g…
Combination of sound, vision, and drones that smell like blue cheese might bring fuckers down...

All you say is so true... That would make you a spoil sport, burst my bubble... I am going to have a little cry in the corner now. I really wanted a AI powered, laser equipped, mosquito hunting drone for my house. After all, what could possibly go wrong?
Shrug, add a nice zoom lens to make it's effective range several meters instead. Of course it would be far sighted but maybe you know most mosquitos will be several meters away anyway. Or have 3 cameras, one for the cm, one for the m and one able to zoom many meters to look at known problem spots like puddles or a bird bath.
This work (I think) worked with the mosquitos 30cm away with a servo scanning Pi Camera (1080p) and a 1W laser. To work in the real world - cover a whole room or terrace - presumably a much higher resolution camera (or much faster scanning system) would be required. Even a 1W laser is dangerous to eyesight, if it was being fired at targets mingling with people. The system could be mounted on small drones that would p…
Good luck detecting a mosquito optically from a distance of several meters using a cheap camera and Raspberry Pi. Oh and you want to do from a moving drone. That will certainly make it work! Just look at the images in the article - the guy's best result was detecting a black speck appearing on a nearby white wall with some 60-70% reliability (based on his own numbers). So you would be missing a lot of mosquitoes - bu…
You need a good way to tell that you're on target. The way to do that is to use the vision system only as a search radar, to find that there's something to shoot at and approximately where it is. Then point the laser near the target, at low power, and start scanning around the target. Modulate the outgoing beam, so you can see when it's illuminating something. Get range from time of flight. When you find something worth shooting, go to high power and take it out.
This is roughly how radar-controlled anti-aircraft gun systems work.
An ordinary UV lamp with bug zapper will probably be more effective.

It would probably be too slow (or you'd need crazy high pressure). The mosquito would have plenty of time tom ove out of the way, especially since it will probably make a sound when shooting the liquid. The advantage of using a laser is that it's basically instant and quiet.
You think a mosquito can dodge a speeding blob of water? It can barely dodge stationary objects. It's basically a homing missle for co2
Most are indeed very lethargic, but there are some much more agile variants out there.

> the idea of robotic drones armed with lasers roaming around is beginning to sound worse than the mosquitos. I don't really mind mosquitos outdoors, what I really hate is when I'm trying to sleep and there is a mosquito in the room. This means I have to turn the light bright on and spend time hunting them down or fill the room wit a toxic insecticide gas. I would rather leave the room (or stay there with my eyes cov…
