I Made a Robot Arm... in the Middle of my Room! 

How long is your arm? 💪

I still believe you’re underrated with how much editing and funny moments you do

And congratulations for getting nominated for Unity Awards ❤️

As someone who is still relatively new to the field mechatronics, here's some tips that may help from my testing with very cheap materials and supplies (we're talking cardboard and SG90 servos since i'm a high school student) * You could use an extended kalman filter for state estimation for the motors. Sometimes, for cheaper motors or if you use gears (not sprockets/chains), occasionally it can "skip" and give you a slightly incorrect value, a kalman gain function could fix this. Bang-bang filters are also an option if an eKF is too hard * You could use a cheap webcam (or your current one) and use OpenCV with a morphological image processing algorithm or blob detection for objects. Blob detection is terrible in different lightning conditions, and if you wanted to do fast processing, a truncated SVD would be good to use for pre-processing in conjunction with a MIP * A PD/PID controller would be good to move to a position. It's a little more complex than what you have, but it's incredibly useful and has that "easing" motion you're aiming for, specifically with a PID controller. However, a PD controller is better for quick and less precise movements (in my opinion) * A Stewart platform would be interesting to use for the base, if you wanted angular motion, as well (although definitely not needed, would almost be redundant) edit: The field of inverse kinematics is also worth looking into, but from what I saw with the computer renders, it looks like you have something similar going on

I cant even Start to imagine how much work this Video was. 100-200+ hours easily. Congrats, you convinced me to subscribe with just one Video. This is awesome!

I like how you handled those tomatoes

Very interesting all the skills needed to make this: math, physics, 3d modeling, 3d animation, unity c#, raspberry pi with python, html, css, javascript, web server, electronics, cutting metal, and much more! liked and subbed, amazing channel :)

Fantastic video! Love the humor, creativity and production quality, keep it up!

As a developer who has tried to wrangle servos to do what I want, I appreciate all the work you put into this. Earned my subscription 😊

if you like this video, you're not the only one! I got nominated for both "best devlog" and "entertainment value" on the Unity Awards! Go vote here: awards.unity.com

The quality on this video is top notch. Love the animations and how everything flows together

The production level in this is off the chart. Even forgetting about the content, which is great in itself. You just gained a subscriber.

Thank you for this Jelle, I had a blast watching :)

This channel is beginning to turn into an engineering channel and frankly, I don't hate it. Keep it up Jelle! I love seeing all the cool stuff you create :D

This is legitimately the coolest channel. Amazing job (as always) Jelle! 🍻

Mate, this is what I call talent! The editing is amazing 😄

Love how you go into more detail and keep viewers following along the project. Definite sub from here

This is awesome dude!!

I've been wanting to do something like this since I first saw Portal. Planning to build a small-scale GLaDOS to act as a smart home hub, and to have other useful features, like a tracking light source, Kinect camera for scanning, speakers, and room for expandability. It's hard finding the time though to dedicate to a project like that, but hopefully someday.

You’re creativity never fails! Keep up the great work!

I am impressed by both your engineering skills and video editing skills, great job bro!

Dude this video is awesome! Just found you in my recommendations and you’ve definitely got a new subscriber! I can only imagine how much time went into making this! Keep going!

You're a LEGEND! Thanks for this epic Adventure. Good luck for the Unity award thingy!

This is absolutely amazing, the amount of skills and talents needed to do this is very inspiring and impressive!

Fantastic project and great sense of humor! Thanks for making an inspiring video!

Great projects, I would suggest adding code to manually set a position/ positions and have it as a preset. so you could just press a button for example when you want the arm to lower itself to add an attachment, or position itself for a selfie, or do a panoramic swipe, etc. really cool project :)!

Jelle: Updates Me: Smashes like Me: starts the video You're very underrated for the amount of work put into this! Nice vid!

This was fun to watch! and thank you for the explanations, I enjoyed learning how it was made :D

This is insane! Extremely well done Jelle!

These videos are incredible I hope your channel keeps growning.

I’m 7 minutes into your video and I just wanted to say that this is the highest quality video I have watched in a long time. I love the creative energy from this and I can’t wait to see the arm in action! Keep being awesome B]

Subbed! Really high quality and fun to watch!

This was a great watch, good content. You're inspirational!

The humour, the smooth transitions, the intricate engineering, someone get this guy the recognition he deserves!

You should add a piston just before the rotating end bit, so you can extend the arm to reach around the room without it taking up a ton of space

that's so cool!, keep up the good and hard work jelle!

Very underrated! Great work my friend. You deserve at least 1m subs for this quality.

Make Glados OUT OF that arm

Mein größten Respekt für deinen Roboter! Mega cool!!!

We are highly impressed with the design and functionality of your robot.

You're such a great guy who knows how to hide the pain behind these projects and show us only the fun part..

Amazing project Jelle - so cool!

Dude this video alone will make your channel go viral. Great stuff

this is really cool! you should probably have used stepper motors for the arm joints tho, as i dont think servos are very strong (hence the slightly jittery motion)

Dude, I was just thinking about getting/making one of these! xD ...Except I couldn't actually think of any uses for it, so I was procrastinating. But now that I see how effective the boxing glove attachment can be at eliminating those pesky greek temples that keep popping up around my room, I think I'll have to get cracking! Thanks for the entertainment and inspiration. :)

Can't wait to watch more of your videos! This is my first one and I've subscribed!

This is the first video I have seen from your channel and I love it. Subscribed

Amazing video and project! Huge respect to build something like this! I am actually also building a robot arm and I really like your's. Can I find the code somewhere (would be really cool)?

You’re creativity never fails! Keep up the great work! If you’re looking for ideas, maybe look into AI video recognition? You could make your arm shoot balls at intruders 😝

i think this is awesome work man. Keep up the good work

This video just became one of my favorites videos on yt, everything is just sooo goood

I have always dreamed of building my own little robot arm but I know whatever I could come up with wouldn't even be half as good as this and any commercial solution would probably break the bank for how much I would use it. You did a fantastic job, great video.

Wow that's a crazy amount of editing, animation, and all that on top of the control engineering, mechanical engineering, and electrical engineering! Well done! Ive been thinking of making one of these myself and you gave a lot of great ideas (slip rings!)

Robots are awsome and you're also awesome for sharing this with the rest of the world.

Love it! First time seeing your videos, like your style

El primer video que veo tuyo y me he quedado flipando. En serio, impresionante. No se como no tienes 200 veces más suscriptores... Me ha encantado. Saludos desde España!

Man you are so talented and funny. Keep going, you will get what you deserve !!

Dude, your videos are actually great. I would have though you had millions of subscribers! I am sure you will grow very fast.

This is amazing and also a PSA on the importance of emergency stop buttons. Very cool.

Subscribed and liked! I really appreciate the work you’re putting into these videos!

Bro you are hella underrated! the quality of these videos is sublime

This is super cool! I wanted to make something like the gantry design to be able to go around the edges of my room so I have an effective reach of my whole room, but after seeing this I'm reconsidering

WOW! The skill! The content is wonderful, the jokes are well ... pun-chy and the editing is *chef's kiss*!

Pretty cool!!! One thing you can do is that...make the arm with the camera attached follow your face like a cameraman(like they do in tech events), it would be really cool.

Amazing video-making skills there. I really liked the idea of having a personal robot arm in my room.

Got this Video recommended on my main page and I must say I am very impressed! Loved all the jokes and the overall editing. I have no idea of engineering but the video is great!

I love your iterative design technique 😍 👌 ❤️

IT'S SO GOOD I'M SO HYPED OMG!!! It would be reaaaallyy cool to use the phone/camera attachment with face tracking. Detect faces and move the arm accordingly! OpenCV would do the trick for your current tech stack for this project I guess.

I really like technique and construction so it was really interesting to see in what kind of problems you run. Also your way of explaining stuff was really humerous too, in combination with your accent really funny, like the mix.👍

This was a fun video to watch, I really enjoyed to design process!

I am so in love with your channel 😍 I appreciate all the work you are putting into your videos

now this is entertainment at its best loved your video glad i stumbled on it

Oh my GOD What a Quality Level!! Bravo!

First time seeing your Channel, and I absolutely love it

Love these videos ! Very creative and underated!

this was amazing. your super talented and smart as hell bruhh

Now I want a robot arm in my room... Thanks for the amazing video as usual, always an inspiration to watch your content :)

Pretty cool man! Gives me portal vibes!

Amazing work. Would love to see this with more powerful motors to smooth out some of the wobbles the arm has when extending

I loved seeing from the beginning to end thank you for sharing

Bro your editing skills are phenomenal. So very entertaining

The video was os entertaining! Kudos mate!

This looks much like the UR5e! Good Job!

literally one of the small amount of creators who actually do cool stuff, keep going dude!

I joined it, thank you. I fully understand how much have you spent on editing.

That's some serious Aperture Science stuff going on, man. Nice job.

Awsome vids! Leuk om iemand tezien uit de BeNeLux met dit soort content! Mijn sub heb je meer dan verdiend!

This is great, hope I can learn from your lessons!

AI following mode, for cameras and like holding stuff for you, just an AI with voice so you can say "Ceiling Robot, smash the hardest you can right downwards" and cool stuff. Keep up with the good work, Jelle!

man that robot arm is pretty sick awesome job

can't believe YT took this long to recommend you channel! Sick robot arm!

Holy shit your editing style is amazing

i can’t say what is more impressive: the project or the video editing

love the idea I would love to see a v2 using stepper motors and/or a planetary gear for extra power and smoothness and maybe attempt to go for open-source software to make it run more smoothly and possibly give it more functionality.

Amazing video Jelle, I have been planning to do something similar but with something with more holding torque for more stability + load capacity, and adding the ability for the arm to know what is attached with the ability to apply a default behaviour. For example a camera linked to a graphic AI chip which would allow your face to be kept in a certain area of the video with the ability to react to gesture control.

Amazing video editing and great use of ar

Man this is pretty awesome and you are very smart. One thing though I would recommend you put an e stop for machines like this.

I watched in 1 week all your videos :) I can't wait for the next video

This was a triumph! I'm making a note here, 'huge success'.

besides you being great at what you built, the editting on this video is awesome!
