Could you post the files like you said in your video Omg he put them up finally!!!

[@TomS699]

Still no update ? Edit: he did it !!!

[@FailedSquare]

i love that they solved it by just not looking at the turret

[@1943vermork]

Need to train the system with side, top and rear pictures.

[@IvanDorozhkin]

​@@1943vermork or add some sort of buzzer when object intersect perimeter. May be they will look in this direction and...

[@matthewbartos2971]

My solution would be making a 'virtual' room this involves cameras in the corners of the real room and then uploading the real footage as updates to the virtual room, this will give a 3d position for all objects in the room and not need anything or anyone to face a specific direction to be detected. This also should help targeting because the cat is fully defined as a 3d object. Other than that this was an awesome project and was really neat to see how fast the cats learned.

[@haydenc2742]

So very cool...I wonder if a laminar flow nozzle would shoot a better stream of water Awesome on the design...and absolute perfection on the SMD soldering!

[@riduanmuntasir1801]

Welcome back from the time capsule! 🚀 Part 2 after a year? I guess patience really is a virtue!

[@NickElectronics]

Good job. I like how clean your designs look like :)

[@EliteWorm]

That’s what I tried. Thank you Nick!

[@themulticore]

Great! You can try Yolo8n detector which should work fine with RPI and similar computing boards. Besides, on top of the detector you can also setup to recognize batch of cat skeleton keypoints as potential places for aiming. Thus, it will allow to adjust the system to make this experience less harmful for cats avoiding headshots as much as possible.

[@Chris_hsr]

You should sell pre-build versions of it, I'd immediately buy 3 of them...

[@GramKrakerJG]

Check out whatever “Frigate” uses. It can reliably detect a cat from different angles.

[@bryanst.martin7134]

Great thinking on the printer nozzle!

[@KG4JYS]

Next time, check out a board called the orange pi. It has a rockchip processor which is faster than raspberry pi in every way. Also, unlike the raspberry pi 5, you can actually buy the thing.

[@alyti]

and they probably don't advocate for shitty pigs spying on you 🦐

[@EliteWorm]

Checking it right now. Seems like a board to consider for future projects! Thank you

[@ltbackfire]

Nvidia jetson not good for this? From what I understand it's made exactly for this kind of tasks

[@jovaraszigmantas]

amazing video, those cats are smart aren't they

[@schrodingerscat1863]

If you were going for a clean build you totally aced it. For a home brew robot that looked super professional and worked perfectly. If you had also had the thing make a warning noise just before firing after the first couple of shots you could have got rid of the water and just had it bleep at the cat. Cats learn pretty fast and they would associate the noise with being sprayed. Seriously though I totally need one of these to stop my cats chewing my house plants. 🙀

[@EliteWorm]

You made a very good point! Noted!

[@bryanst.martin7134]

Can you teach it to recognize the patterns of the Cat's fur? Furry blob on table, what pattern? Target just in case!

[@asurbernardo6478]

That looks so clean, congrats on the project! I actually tried to do smth similar but using a steel pressure tank made for air spraying, definetly overkill as I found out later... I stumbled at the same hickup as you did, there are no accurate haar cascades to identify a cats body, only faces... as for the refresh rate I experimented with an SBC with an integrated NPU, which could also unlock more "smart" OpenCV options like YoloVx, which could be specifically fine tuned with a public cat dataset (I personally tried a Khadas VIM3, they have a non RPi compatible pinout, which could be a bit of a pain and you may need to modify your PCB/Software but they come with a 5 TOPS NPU baked in)

[@EliteWorm]

Thank you! And good luck with your project 🙌

[@melnick1985]

Absolutely fantastic work

[@devised4234]

Make another to look at the cat from another angle! Plus, it’s more awesome

[@Leo99929]

Train the system to detect cats from all angles. People think AI needs perfect images to detect things. That's the opposite of the truth. You need to show it the dirtiest images so that it's trained to know how to deal with edge cases. You probably want to train the classifier on a decent desktop rather than the Pi or it might never finish...

[@EliteWorm]

That’s a good idea! I should try that. Thank you Leo 👍

[@PCBWay]

Welcome BACK from the time capsule!!

[@roberttco1]

So… when will you be selling this? I NEED it now!

[@git-push]

Outstanding job, keep it going

[@viniciusnoyoutube]

You can train the AI with photos os all angles from your cats. It gonna be better because your cats has some distinct colors and patterns.

[@SpencerPaire]

Great build! Excellent design and surprisingly economical! Also your cats are so cute. I would have shown my cat, but I don't want him to be scared kf the robot, lol.

[@picapaukrk]

Amazing work! I was looking for something like this for over a year now. I tried 2 diffrent projects that used sprayer but there is always problem with getting enough force from servo or dc motor. Your project is not on thingiverse, will you upload soon or it is postponed because of "cats without a face"?

[@spectre7529]

Make them wear a collar with tracking device in it

[@434stalinc]

Where can I buy this

[@opposites-369]

I know that sounds from Germany soldier from game "Commandos". I remember for the first time play that game at 1999 from " Chip" Magazine

[@netroy]

Commandos was a fun game indeed 😅

[@dleivam]

it reminded me of the scene of the movie terminator, where the T800 points the laser to sarah conor's forehead

[@MrJocomomola]

Nice, you had the same idea as I had with the drill guide for the brass inserts

[@nicogyro7525]

Great idea !

[@TomS699]

In the video you say that the STL's are on thingiverse. There is nothing there except your 9 Previous designs of things unrelated. Could you please post the STL and Files? Edit: HE DID IT 🎉!!!

[@EliteWorm]

Hi Tom! Can you check it again? They should appear now!

[@TomS699]

​@@EliteWormomg ty this is awesome 💜

[@SamirSyr]

Phenomenal😍👌🏻

[@johantjie]

This is epic! Well done

[@battokizu]

Whats the range on this thing?

[@AdityaMehendale]

In fewer than twenty years from now, governments are likely to deploy similar systems to keep "disobedient" citizen under control. >Shudder< . Cool demo, though :) and deliciously clean assembly! Loved the "laser-cut-sandpaper" trick.

[@AdityaMehendale]

PS - the "mist-generator" issue occurs because the water is not able to gain potential energy before it reaches the restriction. IMO, if yo fill the front 90% of the tube with gas (air), this can escape readily, giving the pressurized tank enough time to transfer energy to the water-column. Then, when the water actually reaches the nozzle, it will have enough momentum to delaminate as a jet instead of atomizing. Just a hypothesis. Haven't thought of a KISS-implementation either.

[@gazehound]

Yap

[@stefanguiton]

Excellent

[@zzz_ttt_0091]

nice

[@alis7441]

Nice!

[@michaelkazmierczak5644]

This is what i'am searching for. We have Chicken and Guests in the Chicken House. So i think maybe the same wy like you, but no for Cat's. If the Chicken are in the Chicken House and need to feed no aktion will be start, but if there are no chicken and feed i need to Taget this Object. So cool this ready to work 2 see. If it possible to Buy it build 4 work as well? Thank you.

[@riduanmuntasir1801]

After one year, he realized that he had a KZbin channel.😑😑

Well, I have a lot of questions. Why are we so impressed by technology but do not think about the injuries and pain that a cat could suffer? It's ridiculous how we have forgotten what it means to be human and to respect and love animals, especially those we bring into our homes. Why didn't you feed your cat properly? Why do you leave your cat alone with your meal? Don’t you understand the extent of your responsibility and all the possible consequences of creating such technology and demonstrating its value in this way? Imagine yourself in "cat's paws." You are hungry, your owner has not fed you properly and leaves you alone with food, or JUST leaves you with a delicious meal. You are a small cat and do not know that your owner, instead of being responsible and caring, has put effort into creating a machine that directly shoots water and could potentially break your skull or paw (when you fall after the shock). Well, haven't you imagined that? No sooner do you post this video to show how you are dealing with the cat's desire to steal your food, you will make a great impression as a smart and inventive person, but are you sure that you show yourself from the good side? Maybe think about your pet and put all your effort into creating positive things. For example, your machine could help develop a face-recognition function for crime investigation. I am sure you can channel your excellent skills in more constructively way.

[@FlufferDredge]

😢😢 get over yourself 😭

[@EliteWorm]

Hi Adele, Thank you for leaving constructive criticism in a respectful and reasoned way. However, I must tell you that the situation is not as serious as it seemed to you. The cats are very well fed, it just happens that one of them is very playful and curious. Her reaction is not from pain, it's just the shock from something unexpected. The water jet doesn't have enough pressure to hurt. I tested it beforehand! Also, if you notice, the laser is not activated so as not to damage her eyes. Cats are easily scared by anything (sounds, themselves dropping an object on the ground, etc.) and overreact. As I mentioned in the video, after a few shots she no longer jumped on the table. You can rest assured that both cats are very well cared for and happy. Don't worry. Thanks for your comment!

[@kenkeiter]

If you're wondering why this has 447 likes out of 12k views, it's because shooting a cat with an airsoft projectile is pretty universally considered animal cruelty in the US.
