Waypoint Guidance with an Amateur Rocket
Vložit
- čas přidán 26. 06. 2024
- My fin-controlled rocket DIAMOND-X can now fly to waypoints in the sky! Flights 3, 4 and 5 were all waypoint guidance tests. One of these was very successful, with miss distances from the waypoint measured in inches. This system is used to fly the rocket into the wind, so it doesn't land as far away after descending on its parachute. With about a 6 inch miss distance from the waypoint, I think it has earned the "precision" title.

BPS: I’m being intentionally vague so I don’t piss off ITAR police
Lafayette:
Real
beyond based
This is mostly showing the results, the BPS guy actually shows details of his design and build process.
ITAR compliance is for cowards
Lafayette has good guidance but his rockets stay under 1km so it's no biggie
BPS on the other hand is trying for a space shot which not only has enough altitude to reach a airliner but enough payload to shoot it down too
Yooo....according to bro ITAR stands for "I Talk About Rockets".
😂😂😂
People don't talk like that. Surfers were made fun of because they called everyone "bro" and sounded unintelligent. If you want to be taken seriously in life. Don't use "bro" as a replacement for "he/him/his"
@@RedFail1-1 Bro like, no bro takes you seriously either bro, becuase like your telling other bro's what to do, bro. Which is like, so much more not cooler than using bro, bro. Not cool, bro.
Bro.
@@RedFail1-1 No one cares that much about someone saying bro. Go outside big dog.
💀💀💀💀
Man, being the DOD guy who gets to monitor your channel must be a sweet gig.
Yeah, people over at Raytheon, Lockheed Martin and Northrop Grumman are shitting their pants because homeboy is about to democratize Sidewinders & AMRAAM's for less than 1/1000'th the over bloated DOD budget!
Now maybe Ukraine can hire Lafayette Systems to start producing MASSIVE quantities of MASSIVE long-range 🚀 to liberate their territory & pound Putin into submission, forcing Putin to sign an UNCONDITIONAL SURRENDER of all occupied territory!? 😁👍
You misspelled "FBI"
Dude is building a sidewinder missile
Not really.
@@meanman6992 though he might be building a FPV, hot launched, ducted fan, cruise miss.... I mean drone
Dude wants the dude get arrested
Looks more like an R-77 tbh
Ssssshhhhhh
Super cool! Also dude I'm telling you, control roll with just one fin! It's so hard to get good roll precision while using all four fins and the pitch/yaw disturbances are basically zero for using 1
Thank you! I was playing around with slightly higher roll gains this flight and you can see the limit cycling towards apogee :( I’ll try using one fin for it next flight, should be fun to compare performance!
Ayy,it's my boy Joseph Bizzlington

It's quite fascinating that currently we have resources available for the general public to build a rocket brain like this :D Imagine doing that in 1950's
Back in the 2000's there was a guy in New Zealand who built a pulse-jet rocket using only parts ordered online. Supposedly it would fly up to 160km and deliver a 10kg "package".
Apparently this guy took part in a British TV show called Scrapheap Challenge. He constructed a working pulse-jet out of scrap in about 10 hours. It was then attached to a kart that got up to 64km/h
@@ralphm6901 a pulse jet is the most basic form of jet engine anyone can make one you literally just bend a metal pipe into a long u shape and a fuel source in the middle
@@BobaPhettamine It's also easy to make a torch using a lighter and a Febreze can, doesn't mean it will perform as well as an oxyacetylene kit. A pulse jet that can reach 64km/h and a whole *Switzerland* worth of range is nothing to sneeze at.
Bros a walking ITAR violation
Bro's getting a job offer he _can't_ refuse from lockheed martin
@@Bomkz better than getting an offer he can't refuse
@@kiq4767 that's what I was implying. They know he can build this shit, so either accept a lockheed martin job offer, or spontaneously go on an extended vacation/impromptu "retirement"
All I'm gonna say is "Tactical and Strategic Missile Guidance vol 6 "
The safety culture that armature rocketeers keep is really awesome. It reminds me of what the RC multirotor hobby was like before the uneducated got hold of drones from DJI and other companies, and governments quickly banned everything. That safety culture will keep the hobby alive and thriving for as long as it is maintained. You guys are awesome!
I agree that people fly where they aren't supposed to and that has caused a *ton* of issues for those of us who practice proper safety. But it's worth mentioning that not everything was perfect before the DJI influx. RC hardware and software has gotten sooo much better, safety-wise in the last few years. I remember a bunch of runaways, wrongly set failsafe modes with never to be seen again equipment, just straight up bugs in esc software, burning drones and whatnot. All the old timers that I know fly without prearm switches and even mentioning it gets met with scepticism. Some hand-launch or even hand-land their drones. It's just a hobby that tends to attract slightly insane people 😂
Raytheon told me they would like to talk you
As the FBI...and the Chinese Ministry of State Security...and the FSB...and two guys who claim to be from ISIS.
The missile knows where it is because it knows where it isn't! 😂
Came for this comment, was not disappointed.
I’m still impressed you just got the flight control system to keep the rocket from spinning! The other stuff is just, wow…. 🤯
This is one of the most professional rocketry video I’ve ever seen on CZcams 👍
Wish I could hit the thumbs-up more than once! Very professional and clear. Thank you.
The missile 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. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the missile is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was.
The missile guidance computer scenario works as follows. Because a variation has modified some of the information the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.
Wow I knew that someone would know this. That video explaining rocket guidance is amazing
Ah, good. Someone already made the joke, so I don't have to.
0.00001 nanosecond after he post it
The ATF: *KNOCK KNOCK*
You and BPS Space need to talk, he’s building up to a space shot, some of your R&D would probably be useful. Also please post some sort of articles for fellow amateurs to implement and understand what you have built, please. I’d love to understand the electronics and code side of this better to basically do the same thing but with side mounted cameras. Not saying share code btw just understanding concepts and software language better in context to these sorts of things.
they already do. We are all in the same discord channel.
@@ThePhantomRocket can you give the link for discord channel?
Give the dc link pls
@@shivayyahiremath2622it’s through the BPS Patreon
@@ThePhantomRocketlink?
It's crazy how many people don't understand ITAR
Wait.... Are you saying the US State department & Pentagon In all actuality DO NOT sit at their desks watching BPS Space & Lafayette Systems CZcams 🚀🚀 videos!? 😁😁😜😜😜
You are 100% on a watchlist! Great vids!
I worked with the fin mechanism of a guided missile for a large defense contractor and it’s very interesting to see the difference between what you’ve come up with and what is used in the field.
Mind telling….👀
Fins are incredibly difficult to use for rocket guidance because they give you an enormous power of steering in all axis. 1 degree off and your rocket will break under the high g forces… This rocket is a masterpiece!
THE MISSILE KNOWS WHERE IT IS
super impressive. extremely high level engineering. its gotta be so satisfying seeing your guidance system working in the air.
Have the alphabet people knocked on your door yet? This thing is sweet.
He’s good there’s no talking between the camera and the flight control system.
lmao, what a description
What do trans people have to do with rockets?
My curiosity won, and now I'm on the DOD's watchlist
It's encouraging to see someone move the state of the art of rocketry ahead....good work!!
**The US Air Force is requesting your location**
Congratulations 🎉
Welcome to the 3 letter agencies list 😂
Your production quality is getting better as fast as the guidance system! Keep it up! Love your videos! 🚀
Great work so far! I can't wait to see the next few flights!
This is gonna be a banger.
Outstanding presentation of the system. Looking forward to Hatchet.
Just admit it…. At this point you just trying to build a diy javelin missile😂
In Germany for example, building an amateur rocket with any kind of control mechanism able to actively modify the flight path is illegal, and you'd get into very serious trouble for it (possibly jail time), because it's considered military weapons technology here. Kudos for including that section on laws and safety at the end of the video!
Haven’t even watched the vid yet and I’m less than 30 seconds in and i already subscribed, this is the kind of content I love to find on CZcams
i allways thought there was a reaons for youtube rockets to go only go up, i think youre reaaallyyy pushing the limit here, i love it
i'm downloading this
I'll have to install a few of these on my property so when the neighbors piss me off... lol
Fantastic vid. Really cool tech and amazing footage. The last video to were cool but this one was next level. Can’t wait for the next.
Incredible flights and precision!
Seriously awesome stuff!!!!
Awesome video as allways! 🥳
Thanks for the tutorial! I'll go build a guided missle right now.
idk why but the fact that he uses names like Data Link and INS is amazing, probably because i'm using to hearing it when i'm playing DCS but i love it
Dynamic waypoints when
Nice work. The level of control is impressive. Those onboard camera sounds are sweet.
wow that’s gotta be the coolest thing i’ve ever seen
We shoudl seriously turn this into a hobby just like how drones and RC Planes turned to a hobby.
This would be so much fun.
Did you drop the /s?
Bro doesn't know amateur rocketry is a hobby. Check this guy out! 😂
Cool stuff.....keep building and flying
Nice work!
I see the mignature of something that looks like a missile, I go look and its literally a missile !!!! as a nerd that likes rocketry and engineering, this is like the dream, also, that channel name sounds like a french company that would make jet fighters and missiles, this feels like at the limit of what would be legally allowed on youtube and I love it
Well done. Need a steerable chute to bring it back to the launch pad.
Really unique content. Thank you it
For representative statistics, it would be great to randomize the waypoints👍(maybe within a certain radius)
Chatgpt is truly incredible
The joy of rural life
Next Video: ITAR Raided my Home
saving this for later
Amazing video, you've got my sub.
ITAR doesn't scare bro
But doesn’t the ITAR only apply if your selling the missile
@@MalzysFoldraankonid well they're pretty naggy about spreading information about building missiles or more specifically, export information or technology about building guided projectile~ as he also mentions towards the end of the video
@@bumbowo okay thanks I looked up a bit about them and could only find exporting stuff so I was confused thanks
🤦 none of this is covered under ITAR
The sidewinder for the everyman.
Homemade sidewinders, I will be following
The rocket knows where it is, by knowing where it isn’t
Damn I love your videos so much
Pls keep it up
btw, the AIM-9s have a control system, which are increaseing their control athority step by step after launch. Seems lke a good idea for Diamond-X as well
Wow, nice
Are you using Euler angles (rotated) or are you using quaternions to determine the current orientation of the rocket?
Bravo.go ahead
Criminally underrated channel
Don’t use that word here please 😂
CIA called, apparently some guy they named "ITAR" is searching for ya
Instead of printing parts at 100% infill, print them with 99 walls (obviously that many walls won't actually print) - walls provide strength along the axis you need for the application of chute line anchor.
you have officially blown up and became viral imo
It's good he called it "Waypoints" not "Targets"
Insane
CZcams: less than 30 rounds in a magazine
Also CZcams: hey kid wanna see how to make an AMRAAM in your garage?
Finally someone, who said what joe was too afraid to say
They came a long way
Mr Wernher von Braun junior. I especially love thouse views from rocket itself. (no pun intended).
What if your way point is moving like real life scenarios? Love this video and also the safety part.
This is motivating me to try and make a guided missile for my large-scale RC planes
I think that might be a crime
Skymaster F-14’s chasing each other with functioning sparrows would be the future of xtreme sports!
@@Gl1tchy_B01_09 Yeah, I'm not gonna actually do that. Just in theory.
I remember when Mark Rober tried making something and someone in defense told him it was illegal to do so 😂
looks like bro developing his own air defence.😅cool
Congratulations! You made a missile!
Dang that is very cool. I'm an engine electronic controls guy from a long time ago. ITAR can really be a PITA.
So guided missiles are okay to build, as long as they don't go kaboom! That rocket could be used for interception purposes
You should setup an algorithm verification pipeline which tests the control sw in sim everytime you make a change.
It is a bit more work in the beginning but will pay thicc dividends in the end.
Cheers!
I was at Muncie,on 4th flight,I have your video on my ch. Cool stuff back in the day we couldn't have Guidance due to 911. I'd love to print your rocket for my fun.
Based video
Someone pleeeeease, give this man a job at the militart industrial complex. Innocent lives wont be lost by themselves
I love the external design of this rocket. Do you have plans available to recreate it as a "dumb rocket"?
i can sense ITAR at your doorstep
Make it go horizontal at a given altitude and make propulsion last much longer.
Go to several GPS waypoints and make it scan ground topography and cruise at xx meters above ground. 😀
The accuracy of this system is extremely impressive, even flight 5's late activation and missaligned roll was handled exceptionally. How did you tune everything? It seems hard to select good constants, but you also mention it does some calibration on initial lift off, does that help somehow?
in the future try and build a cool launch system. maybe with kinetic energy (flywheel) or an electromagnetic rail or something.
"I am not supplying code, cad or PCB files for this project." BORING how else am I supposed to make ballistic weapons that can hit a fly a content away????? Fund my own researchers???? Cringe.
Hatchet, the rocket/drone thing with a ducted fan... I think that called a cruise missile :D
Congrats!!!
1. You could put 2 or 3 waypoints on each flight to gather more data.
2. How precise is your measuring system of actual path and how it works?
With an active waypoint updating this could be a decent surface to air drone defense "rocket".
فيديو جيد، وأنا أقوم بتدوين الملاحظات
Do you think it could be helpful to check at the transition of Launch-Dir-Hold to Waypoint whether the angle or resulting force between the current trajectory and the predicted trajectory would exceed a threshold for safe maneuver?
Has this man built an entire GPS guided Sidewinder using the metric system?
This could litterly be a good way to make crude but effective guided missile guidance systems for countries that can't make state of the art weapons or one that wants to make something cheap and easy off the shelf components or just both is very useful i think this is possibly the next thing for cheap low grade effective precision guided weapons
Congratulations! You won a visit from the US department of homeland security or something like that
