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

I made a fully articulated robot arm! on my ceiling. It can freely move around and do all kinds of cool stuff.
The arm is powered by a Raspberry Pi, controlling stepper and servo motors for each joint. It can be controlled with a graphical web interface build using the Unity game engine.

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

[MP-ring]

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!

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 :)

[AXISMotionStudio]

And congratulations for getting nominated for Unity Awards ❤️

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!

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

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

[eccbocceccbocc]

Holy shit your editing style is amazing

[prof.tahseen]

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.

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

[_and_only_Crjase]

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

[iHeartGameDev]

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

[kundanyadav]

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.

[huddlespith]

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!

[techcast]

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

[ultragames]

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 :)!

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!

[ishankkhurana]

That was really good man. I really enjoyed the video, I was watching this video regardless I have a exam tommorow !!
wish me best !
keep making this stuff. I really like it

[Arya-bywm]

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

[dar.io_j]

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!
