We care, but it's not the drones that we're concerned about ( as we demonstrated, even a small system can remove them), it's the inconsistent and even conflicting explanations. "They're not from a national adversary. They aren't controlled by our government, and they're not private. But, we know they're not a threat even though we have something like 50 federal adjents attempting to recover a downed drone..."
@@TechIngredients Exactly. Them telling us they're not a threat while simultaneously telling us that they don't know the owner/origin is not a logically consistent response. One cannot come to the conclusion about the former without knowing the facts of the latter. It tells me they're lying, that they must know the owner/origin, and if they're so bold to lie about that, I also don't believe them about the lack of a threat.
Normally I would regret spending an hour watching youtube, but I learned more in this last hour than I would have thought possible. Thank you for entertaining, and educating us.
@@DugWagner It was an exciting presentation. The laser assembly needs more work particularly to tighten tracking along with object recognition differentiation. Those tracking inaccuracies really become significant at longer distances. All the same, well presented with high level detail explanations with whiteboard drawings. Well done!
You can also pulse the lasers at the nano and pico second level and get 5-15x the power on target. I have driven them to over 2000 Jules per pulse around 1-3% duty cycles. This sounds useless as the rms power on target is only a little above the constant power mode, but the power experienced by the target is much much more destructive
Do you mean these diodes or some other? These are made for projectors. I bought a pack on eBay some time ago and was wondering about something like that myself. Started designing the pulser for microsecond pulses. I can make nano but not pico.
This channel is amazing. I've been following you guys for nearly a decade now. This is the youtube content that I always pay attention for. Thanks you for this excellent informative, advertizing and human content!

i gotta say.... chris is pretty spot on in explaining how everything works. I myself am in computer science and it was a joy hearing him talk, i hope you guys get him on the team, this video is the best yet!
Loved this one! 2 things that caught my eye: A) Ranging. 8 separate lasers that converge at a fixed distance, from what I could see. The 8 lasers only converge at one distance, with a fixed mount. If small X-Y actuators were incorporated, along with range finding, all 8 lasers could be variably focused on an arbitrary point at any distance from the emitter, thus maximizing the delivered energy. An oval pattern on the test plates seems to indicate that the test plates were not at the optimal distance. A perfect(ish) circle would be what I would expect for perfect range alignment for all 8 lasers. B) Dead target. If the target hasn't moved for X amount of frames, then I'd call it a low priority target, i.e. don't shoot. If it moves, shoot again. Doc, you've gone full blown Real Genius in this one, well done!!! (if anyone doesn't know '80's movies, just look it up and watch it. GREAT flick!) Edit: 1 more thought. Instead of calling it the Kill Switch, why don't you go with the military nomenclature and call it the Master Arm? "Master Arm on" means weapons hot, "Master Arm off" means it can't fire. Just sayin'.
In this test, the effect is minimal. It does increase the focus area a bit, but more than functionally. If it was a long-distance thing, like one end of the warehouse to the other, then some planer adjustment could increase the efficiency.
I was wondering why 2x4 but not 3x3 matrix, the latter being more symmetrical. Instead of steppers, why not use servos? Faster and quieter, otherwise not much different from steppers, IMHO. Aiming system - remove anything massive (like steppers/servos) from moving part. I remember seeing robotic arms where all drives were located inside base. Stainless steel made nice reflection on first second. One may wear goggles but at such power levels it may easily burn through anything.
@@SeersantLoom I like your thoughts! Servos are faster, but less precise. In this application I'd have to say that speed would trump precision, so it would have to be tested to find out what works best. Servos may very well be the best solution. As for mounting them in the base, my thought is that will add unneeded complexity. Putting them on the mount adds angular inertia, but again the cost - benefit ratio would have to be tested.
THIS is EXACTLY why I love this channel. Y'all don't go on and on about one or two topics, you don't really get into politics, and most important the way you deliver your knowledge to your viewers (subscriber or not) is nonpareil to MANY other information/educational channels that I watch and/or subscribe to.

@@itishappy I know I kinda just joked about it, but I was a little taken aback by that.. Like he actually uses the proper eye wear here 47:40, so I just don't get the rest, I don't get how he could be that dumb. Laser light isn't just about what direction the eye is pointing, and he's ALLEGEDLY using a laser with 1.4KW of power and he thinks just hanging some cheap laser glasses over the top of his own, when the actual goggles would be more appropriate, and comfortable to use with eye glasses? I can't imagine the other two people there not pointing out they are useless AND he looks daft.. I just don't get it, honestly I don't get most of that video as as much fun as they are having the end results just didn't really feel that impressive, especially considering their usual content..
The laser knows where it is at all times. It knows this because it knows where it isn’t. By subtracting where it is from where it isn’t or where it isn’t from where it is, whichever is greater, it obtains a difference or deviation.
well yeah that video is an accurate summary of how the guidance works. the missile literally subtracts where it should be from where it wasnt, that isnt a joke or a meme
1600 watts I'd be tempted to declare shooting range safety rules on that thing lol. Even with it unplugged I'd feel uneasy without good fully enclosing laser goggles on.

I love everything that has to do with LED´s (especially LED flashlights) so because of this i am also very interested in LEP flashlights. And i really would love to build one myself (or at least play around with the tech) but i decidet to not do it because i love to see the world with my own eyes. Simple risk assessment.
I have been developping laser welding technology for few years and one of our competitor, TRUMPF located un the US are also offering BLUE laser source to laser weld battery. especially copper anode because blue is well absorbed with copper. These are the only one I knew had over 1kW of blue laser source.
My dad got to the proof-of-concept stage of inventing something like this when I was a kid. This was the mid-90s, He wanted to make a sort of anti-insect laser turret. He didn't get as far as acquiring lasers or anything. Laser pointers were just starting to become cheap, and he had the idea of an array of laser pointers collimated (right word? Collated maybe?) into a single narrow beam. I remember a sort of analog circuit with a bunch of op-amps and odd ICs to detect and target flying insects. Looking back on it now, that's basically how coldwar era targeting and fire control works.
In the days before lasers were pointers I bought a HeNe gas laser that someone pulled out of a broken laser printer. I looked around for something to test it on, and declined to blind the cat. I caught a moth in the back yard, and played the red laser light on it for a while. Did you know moths fly so erratically that you can’t tell whether they’re blind or not?
@@firstmkb My work involves lots of junk piles. A few months back, I found an ancient "construction and engineering laser". Not like a rotary laser level, this thing made a single stationary beam. Presumably a red dot. It was flat, about 2 feet long and 6 inches wide, and about 3 inches thick. It came with a large power supply. I set it aside because I REALLY wanted to take it apart and see what sort of laser it contained, but someone threw it away on my day off. I don't know much about the commercial history of lasers, but the design language was very 1970s.
Every video you make is a great lesson on a broad range of subjects... I wish I could move next to where you live and work as an assistant on all these amazing projects.

Its only in the right channel. I would assume the mic is stereo and cable was bad but looks like he has a wireless one so maybe some interference of some kind. Seems to go away after 8-9min but I'm only nearing 20min wile writing this. I would have just cut the right channel and replaced it with a copy of the left for that segment but not sure how hard that it but shouldn't be that hard.
this is actually brilliant, you only really need to disable the CCD or CMOS censor in the FPV camera to take out a drone, you could maybe even augment it with a passive radar system for acquisition.
Considering the very low likelihood of the drone camera having sufficient optical filtering in place to protect against the amplitude of the laser light hitting it, that should be simple and fast, as exemplified by the damage suffered by StyroPyro's camera while recording operation of the so-called "hair removal laser" that he bought from Temu. But. This also requires that the laser emissions enter the lens within a specific angle of attack, and if the drone being targeted is moving perpendicular to the laser emitter, then its lens is very unlikely to catch enough light to damage the sensor sufficiently, if at all. That being said, if a battery of these laser cannon were set up as a defensive emplacement, aiming nearly directly at oncoming drones, then the optical sensors on the drones would be far more likely to be exposed to the laser beams. Then the defender need only hope that the drones aren't using GPS as a guidance system in addition to or in tandem with video piloting. Finally, there is no such thing as a "passive radar system".
@@dionh70 There absolutely is such a thing as passive / parasitic targetting radars that use radio emissions of other crafts as well as reflections for target acquisition. If you are in doubt about what it is, go read the wiki page about it :) You dont really need to hit the CCD directly, just cook the FPV camera with moderate heat. Most FPV cameras go glitchy just by being on without sufficient airflow around them especially 2.5watt ones.
One of the biggest difficulties in this type of tech is the need to have your beams align/converge at various distances. This requires determining distance and precisely moving each individual emitter. The precise and repeatable movement of all emitters can be handled by a single driver if you mechanically connect all pivoting emitter bases to eachother but it requires considerable precision and tight tolerances. Distance can be measure by a ranging emitter, multiple cameras for binocular (or greater) vision, or a combination. Even then you have the issue of atmospheric distortion once distances become great enough. That distortion can be measured and then phased out but this requires on-the-fly lens adjustments. - It's a simple idea in concept but in application it very quickly grows into a rather difficult task and considerably increases costs. Nowadays, the real-time computation and machine learning based target selection is the "easy" part, haha.
@@TechIngredientsYou should learn to assemble fiber connectors on your own if you're planning this, or move the assembly into a clean room. The diverging electric field tends to draw dust particles to the facet, so that you get frequent "coatings" from burned particles for high power applications.
@@TechIngredientsOh and in case you're actually switching to fibers you should maybe think about seeding with a spontaneous source to reduce phase coherence, and ditch the "laser" completely. Most of these materials have some much gain nowadays that ASE should give you plenty of power, but you don't get any nasty interference effects from lens surfaces.
What buzz? I don't hear anything honestly. But I cannot hear the beep from a thermometer anymore I have to have my wife stand next to me.. He may have something similar.
@@ohioplayer-bl9em There is a buzz in the right channel from using the wireless mics. They are supposed to be recording locally - but perhaps not in this setup.
The military had this mounted on a 747 to shoot down ICBMs around about 15 years ago. They also have a truck mounted drone laser system already. They just don't want to use it against their own equipment, assuming you're referring to whatever tf is going on in New Jersey lately.
@@colinofay7237 With the power of the laser here, stray reflections of this laser are enough to burn your eye's retina in a minuscule amount of time. I don't understand how you could think the way he is wearing it is fine.
Thanks a lot for this excellent video! This is a topic that I have studied but only applied a very long time ago for industrial purposes. The progress made in this field is incredible. If I may, it would have been really interesting to look at the tracking aspect and how the algorithm manages the tracking while identifying drones. Especially if you have a way to see on screen how the object id loop reacts.
If I recall correctly the Navy or Air Force (don’t recall which) had a huge and crazy powerful chemical laser on a 747 as an experimental interceptor project back in the 80s?
And it had the same problem as this system: "STAY STILL DAMMIT, SO I CAN SHOOT YOU!". As in, it really doesn't matter whether you can TRACK a thing - in order to kill it, you'd also need to keep the beam AT THE SAME SPOT on it. For a non-trivial amount of time.
This is your best video ever. You did a great job using existing hardware to meet the goal. The only weakness is the power of the lasers, which can easily be addressed with more powerful lasers. Pulsed lasers combined with increased laser power should be able to punch through even hardened targets.
Chris = pure gold... The single take in the middle of the video with all of the distractions and a moving white board... I dare say that man's got a bright future
One immediate counter measure one can take against this laser, is to paint or cover the drone in a reflective material. (for the wavelength of the laser.) I think this will be the first thing, the lowest hanging fruit so to speak, to laser proof drones. To ensure that this will actually be an effective system, you should try to proof the drones against the laser. (which might be a very interesting video in itself.) If you can still stop the drones despite your proofing, I think you might actually have an effective system. Good luck ;)
QUESTION. What is the min. possible estimated weight of this LASER arrangement and what is the power consumption in Volts, Amps and Wh as well as the "boot time" from switching on to ready to fire? THANKS IN ADVANCE.
So what you’re saying is the laser knows where it is by calculating where it isn’t, it then calculates where it wants to be and subtracts that from where it is
For the AI laser project alone. - A vid about the start of project, why you want to try, what the ideas are and the selection procedure of the laser. Why you are thinking about buying this laser, do we need to watercool? Is there some choice part over the counter, or do you need specialized lenses. How you came to conclusion to ask at MIT. 10 min vid. - A vid about contacting MIT and how you select a partner and a how does that work? I don’t know but would like to know. - The main vid. - A 5 min vid about the costs of the project. Some of these items must be expensive.
Your videos never cease to amaze me. They're always exciting and whenever I see a new upload, it's reason to celebrate. Thank you for the INCREDIBLE effort you put into these.
I was just watching a video about some really strange drones (some claimed as large as an SUV) flying over New Jersey and how they "supposedly" cannot get near them with Blackhawk helicopters and are extremely difficult to shoot down..... and then this video comes up in my feed.... I **ALWAYS** love the Tech Ingredients offerings and the high degree of science being demonstrated in a reasonably accessible format for most people with a reasonable knowledge of sciences, and even good stuff for those with only passing knowledge... Seems like this experimental device could prove useful in reference to the earlier situation.
You mean the civilian aircraft misidentified as drones, which the media jumped on because it's sensational and will get more eyeballs onto their partner's ads?
@EvenTheDogAgrees no offense, but several different videos clearly show drones. I fly drones and it's blatantly obvious these are large drones. And not cheapo sub thousand dollar drones.
@@texasslingleadsomtingwong8751 I fly RC quadcopters too, and while I haven't seen all videos, the ones I've seen passed off as "drones" showed airliners and helicopters. Besides, if I wanna fly a multirotor at night for nefairous purposes, first thing I'd do is kill the lights. You'd have to be a total moron to announce your presence by lighting up the night sky while trying to stay covert. Nothing about these stories adds up. But that's OK; the general public has lost all critical thinking skills. Because "drones" are the new Big Bad (TM) now. Plastic bag gets blown over the runway by the wind? Shut down the airport, we got a rogue drone on the loose! Aircraft gets hit by some styrofoam picked up by the wind? Drone attack! I'm so sick and tired of our hobby being lambasted without any proof whatsoever. If these are actually drones, it's trivial to intercept or even disrupt the control signal, or shoot them out of the air. Show me the proof, not some bigfoot footage of something that might be a drone if you squint hard enough so you don't see it clearly.
I would love to see a version 2 of this. I don't know how practical it would be to do this, but a live 3d model would probably help with object persistence and also, more specific targeting.
Wonderful video, retired Industrial Automation and Robotics Specialist here. Real pleasure seeing some new Tech available, I was not familiar with Yolo, (never needed in my applications but can see it's superior capabilities!) We have come such a long way in such a short period of time. (Thinking back at year 1 of the DARPA autonomous vehicle challenge!) Wondering how Ai could revolutionize the technology and how we might incorporate it into tracking/axis control and error correction vs basic PI/PID control systems in the near future too.
can you kill an incoming tennis ball? You might launch it with a tennis ball launcher, as they are used for training. The launcher would have to be behind a hatch that closes and the hatch would have to be connected to a kill switch that enables the firing as soon as the hatch is closed.
A few things: 1. VERY impressive! Astonishing really. 2. This is almost ready to do probably the most useful task a system like this would have and that is destroying the sensors on drones. If they can't see they can't attack. 3. It eventually needs a prediction function in the software that analyzes vehicle attitude to know how to start tracking in advance so as to not lag behind. Pilots can look at the tilt of an enemy aircraft and predict where it will go next. They can even watch the control surfaces of an enemy aircraft to predict how it will move. The same thing goes for wheels. If the wheels turn to the right then it is time to start tracking to the right. 4. You may need a thermal camera to be able to track through smoke and fire. 5. I know there are folks in Ukraine that would absolutely love to have a chat with you to talk about how they could put this to use right now. 6. You may be at a point where people in our government don't want you to make any more videos about this system. I won't tell them though in hopes of seeing more videos.
Those are good suggestions. A predictive modification may help as will increasing the control loop rate to 100-200Hz. Lidar for range (and therefore size) and thermal imaging are in the works. The only problem is thermal cameras with the necessary resolution and FPS are VERY expensive.
@@TechIngredients There may be some shortcuts that could help without new hardware. A prediction function that puts the system to motion early to account for the logic and camera lag and the flex and mass of the laser system could get it tracking faster. The 60fps camera is already introducing probably 30 milliseconds of lag just by how it must work. A bit of "leading the shot" and letting the target move into the laser might be better than trying to track in real time constantly and having bits of lag in the logic as well as physical system hold it back. The tracking of multiple targets is really amazing for a small low-budget project. Getting it to work with bulky hardware is mind boggling. As it is this system could protect a small area from a drone swarm by damaging sensors. That stack of wood pallets made me nervous! I was afraid a damaged burning drone would go wild and bury itself in there.
Yet again, a great project. it was so funny how you constantly had to pause and think of alternative phrasing for the thing you actually wanted to say, ie "directed energy weapon". Avoiding RUclipss silly censorship is rapidly becoming an art-form in itself. We don't say "explosive material" anymore, we say "energetic compound", etc.
A really nice start. I'd suggest: Replace the belts with gears, tune every part for precision and speed, of course including the tracking system (think about extrapolating the course a bit, too. only trailing behind doesn't cut it above certain speeds), train it on infrared emissions from drones, both flying in daylight and in very dark nights, use ultraviolet lasers (or something else from the non-visible spectrum), stay on one target until it's gone (needs training on drone vs. pile of plastic) and tadaaa there's a very useful product. All of the new training of course also taking humans into account and make sure they are not evaluated as targets. And the test for this: In the middle of nowhere, with high speed drones and pro pilots. A nice variation (needs more precise training and aiming): Take out only the rotor blades.

I was wondering why 2x4 but not 3x3 matrix, the latter being more symmetrical.
Instead of steppers, why not use servos? Faster and quieter, otherwise not much different from steppers, IMHO.
Aiming system - remove anything massive (like steppers/servos) from moving part. I remember seeing robotic arms where all drives were located inside base.
Stainless steel made nice reflection on first second. One may wear goggles but at such power levels it may easily burn through anything.
@@SeersantLoom I like your thoughts! Servos are faster, but less precise. In this application I'd have to say that speed would trump precision, so it would have to be tested to find out what works best. Servos may very well be the best solution.
As for mounting them in the base, my thought is that will add unneeded complexity. Putting them on the mount adds angular inertia, but again the cost - benefit ratio would have to be tested.

The laser knows where it is at all times. It knows this because it knows where it isn’t. By subtracting where it is from where it isn’t or where it isn’t from where it is, whichever is greater, it obtains a difference or deviation.
well yeah that video is an accurate summary of how the guidance works. the missile literally subtracts where it should be from where it wasnt, that isnt a joke or a meme

Outstanding explanation and work, hope you continue partnering with MITERS.
That's the plan.
My dad got to the proof-of-concept stage of inventing something like this when I was a kid. This was the mid-90s, He wanted to make a sort of anti-insect laser turret. He didn't get as far as acquiring lasers or anything. Laser pointers were just starting to become cheap, and he had the idea of an array of laser pointers collimated (right word? Collated maybe?) into a single narrow beam. I remember a sort of analog circuit with a bunch of op-amps and odd ICs to detect and target flying insects. Looking back on it now, that's basically how coldwar era targeting and fire control works.
Is your dad Lowell Wood?
In the days before lasers were pointers I bought a HeNe gas laser that someone pulled out of a broken laser printer. I looked around for something to test it on, and declined to blind the cat. I caught a moth in the back yard, and played the red laser light on it for a while.
Did you know moths fly so erratically that you can’t tell whether they’re blind or not?
@@firstmkb My work involves lots of junk piles. A few months back, I found an ancient "construction and engineering laser". Not like a rotary laser level, this thing made a single stationary beam. Presumably a red dot. It was flat, about 2 feet long and 6 inches wide, and about 3 inches thick. It came with a large power supply. I set it aside because I REALLY wanted to take it apart and see what sort of laser it contained, but someone threw it away on my day off. I don't know much about the commercial history of lasers, but the design language was very 1970s.

Congratulations guys keep going!
Thanks!
The new laser(s) have already arrived...
this is actually brilliant, you only really need to disable the CCD or CMOS censor in the FPV camera to take out a drone, you could maybe even augment it with a passive radar system for acquisition.
Considering the very low likelihood of the drone camera having sufficient optical filtering in place to protect against the amplitude of the laser light hitting it, that should be simple and fast, as exemplified by the damage suffered by StyroPyro's camera while recording operation of the so-called "hair removal laser" that he bought from Temu. But. This also requires that the laser emissions enter the lens within a specific angle of attack, and if the drone being targeted is moving perpendicular to the laser emitter, then its lens is very unlikely to catch enough light to damage the sensor sufficiently, if at all.
That being said, if a battery of these laser cannon were set up as a defensive emplacement, aiming nearly directly at oncoming drones, then the optical sensors on the drones would be far more likely to be exposed to the laser beams. Then the defender need only hope that the drones aren't using GPS as a guidance system in addition to or in tandem with video piloting.
Finally, there is no such thing as a "passive radar system".
@@dionh70 There absolutely is such a thing as passive / parasitic targetting radars that use radio emissions of other crafts as well as reflections for target acquisition. If you are in doubt about what it is, go read the wiki page about it :)
You dont really need to hit the CCD directly, just cook the FPV camera with moderate heat. Most FPV cameras go glitchy just by being on without sufficient airflow around them especially 2.5watt ones.
Also if an FPV drone is a threat to you, odds are that its looking directly at you...
MIT is essentially a branch of the military, so I’m sure they appreciate the R n D😂

"..we shouldn't be smelling these toxic fumes..."

One of the biggest difficulties in this type of tech is the need to have your beams align/converge at various distances. This requires determining distance and precisely moving each individual emitter. The precise and repeatable movement of all emitters can be handled by a single driver if you mechanically connect all pivoting emitter bases to eachother but it requires considerable precision and tight tolerances. Distance can be measure by a ranging emitter, multiple cameras for binocular (or greater) vision, or a combination. Even then you have the issue of atmospheric distortion once distances become great enough. That distortion can be measured and then phased out but this requires on-the-fly lens adjustments. - It's a simple idea in concept but in application it very quickly grows into a rather difficult task and considerably increases costs. Nowadays, the real-time computation and machine learning based target selection is the "easy" part, haha.
3 D imaging and target tracking will be next. More powerful fiber lasers will also allow for active focusing because of the optical simplicity.
@@TechIngredients I'm not sure how effective they are for long range but the Xbox Kinect has a cult following for 3d imaging
Convergence isn't an issue... if the target is so close that you have to change from ∞ - you're already screwed.
@@TechIngredientsYou should learn to assemble fiber connectors on your own if you're planning this, or move the assembly into a clean room. The diverging electric field tends to draw dust particles to the facet, so that you get frequent "coatings" from burned particles for high power applications.
@@TechIngredientsOh and in case you're actually switching to fibers you should maybe think about seeding with a spontaneous source to reduce phase coherence, and ditch the "laser" completely. Most of these materials have some much gain nowadays that ASE should give you plenty of power, but you don't get any nasty interference effects from lens surfaces.

Thanks a lot for this excellent video! This is a topic that I have studied but only applied a very long time ago for industrial purposes. The progress made in this field is incredible. If I may, it would have been really interesting to look at the tracking aspect and how the algorithm manages the tracking while identifying drones. Especially if you have a way to see on screen how the object id loop reacts.
If I recall correctly the Navy or Air Force (don’t recall which) had a huge and crazy powerful chemical laser on a 747 as an experimental interceptor project back in the 80s?
Yes and it wasn't as effective and efficient they canned it.
And it had the same problem as this system: "STAY STILL DAMMIT, SO I CAN SHOOT YOU!". As in, it really doesn't matter whether you can TRACK a thing - in order to kill it, you'd also need to keep the beam AT THE SAME SPOT on it. For a non-trivial amount of time.
They had one in the early 2000s. It was effective. It cost too much money though. It's called the YAL-1.

One immediate counter measure one can take against this laser, is to paint or cover the drone in a reflective material. (for the wavelength of the laser.)
I think this will be the first thing, the lowest hanging fruit so to speak, to laser proof drones. To ensure that this will actually be an effective system, you should try to proof the drones against the laser. (which might be a very interesting video in itself.) If you can still stop the drones despite your proofing, I think you might actually have an effective system.
Good luck ;)
That's a good idea.

Cool. One step closer to being subjugated by the machines.
So what you’re saying is the laser knows where it is by calculating where it isn’t, it then calculates where it wants to be and subtracts that from where it is
Basically, yes.
The devil is in the details. Drive lag and flexure, as well as the finite sampling rate, complicate the process.

@@texasslingleadsomtingwong8751 I fly RC quadcopters too, and while I haven't seen all videos, the ones I've seen passed off as "drones" showed airliners and helicopters.

Because "drones" are the new Big Bad (TM) now. Plastic bag gets blown over the runway by the wind? Shut down the airport, we got a rogue drone on the loose! Aircraft gets hit by some styrofoam picked up by the wind? Drone attack! I'm so sick and tired of our hobby being lambasted without any proof whatsoever. If these are actually drones, it's trivial to intercept or even disrupt the control signal, or shoot them out of the air.

Wonderful video, retired Industrial Automation and Robotics Specialist here. Real pleasure seeing some new Tech available, I was not familiar with Yolo, (never needed in my applications but can see it's superior capabilities!) We have come such a long way in such a short period of time. (Thinking back at year 1 of the DARPA autonomous vehicle challenge!) Wondering how Ai could revolutionize the technology and how we might incorporate it into tracking/axis control and error correction vs basic PI/PID control systems in the near future too.
the way you explain physics is very easily understandable without dumming it down at all. you should publish some books on lasers
Thanks!
Lol the 'f...' at the 46:45 mark haha. These guys are great, nothing like this on YT very unique presentation of everything they do
Incredible technical designs made look super easy. It is just incredible how much knowledge this channel communicates and shows.
can you kill an incoming tennis ball?
You might launch it with a tennis ball launcher, as they are used for training.
The launcher would have to be behind a hatch that closes and the hatch would have to be connected to a kill switch that enables the firing as soon as the hatch is closed.
I am stupid, there is a much simpler way to not hit the launcher: throw it over a wall, the ball curves down, the laser shoots straight.
A few things:
1. VERY impressive! Astonishing really.
2. This is almost ready to do probably the most useful task a system like this would have and that is destroying the sensors on drones. If they can't see they can't attack.
3. It eventually needs a prediction function in the software that analyzes vehicle attitude to know how to start tracking in advance so as to not lag behind. Pilots can look at the tilt of an enemy aircraft and predict where it will go next. They can even watch the control surfaces of an enemy aircraft to predict how it will move. The same thing goes for wheels. If the wheels turn to the right then it is time to start tracking to the right.
4. You may need a thermal camera to be able to track through smoke and fire.
5. I know there are folks in Ukraine that would absolutely love to have a chat with you to talk about how they could put this to use right now.
6. You may be at a point where people in our government don't want you to make any more videos about this system. I won't tell them though in hopes of seeing more videos.
Those are good suggestions. A predictive modification may help as will increasing the control loop rate to 100-200Hz.
Lidar for range (and therefore size) and thermal imaging are in the works. The only problem is thermal cameras with the necessary resolution and FPS are VERY expensive.
@@TechIngredients There may be some shortcuts that could help without new hardware. A prediction function that puts the system to motion early to account for the logic and camera lag and the flex and mass of the laser system could get it tracking faster. The 60fps camera is already introducing probably 30 milliseconds of lag just by how it must work. A bit of "leading the shot" and letting the target move into the laser might be better than trying to track in real time constantly and having bits of lag in the logic as well as physical system hold it back. The tracking of multiple targets is really amazing for a small low-budget project. Getting it to work with bulky hardware is mind boggling. As it is this system could protect a small area from a drone swarm by damaging sensors.
That stack of wood pallets made me nervous! I was afraid a damaged burning drone would go wild and bury itself in there.
Great learning, dialog, education and fun!
Im a truck driver and just listened to this while driving. What a wonderful show!!! I felt like i was tinkering with you
That's great!
Thanks.
Yet again, a great project. it was so funny how you constantly had to pause and think of alternative phrasing for the thing you actually wanted to say, ie "directed energy weapon". Avoiding RUclipss silly censorship is rapidly becoming an art-form in itself. We don't say "explosive material" anymore, we say "energetic compound", etc.
Even when I thought you can’t exceed your experiments / my expectations, you NAILED it big time. Deep RESPECT !!
A really nice start. I'd suggest: Replace the belts with gears, tune every part for precision and speed, of course including the tracking system (think about extrapolating the course a bit, too. only trailing behind doesn't cut it above certain speeds), train it on infrared emissions from drones, both flying in daylight and in very dark nights, use ultraviolet lasers (or something else from the non-visible spectrum), stay on one target until it's gone (needs training on drone vs. pile of plastic) and tadaaa there's a very useful product. All of the new training of course also taking humans into account and make sure they are not evaluated as targets. And the test for this: In the middle of nowhere, with high speed drones and pro pilots.
A nice variation (needs more precise training and aiming): Take out only the rotor blades.
