Finally an arduino tutorial actually explaining the process

[@Electromakerio]

You're welcome :)

[@Tarbard]

If i'd known it was Bitluni I would have clicked faster :)

[@larrylange7949]

Mal wieder ein super Tutorial von Dir und obendrauf noch mit soviel Humor. Top LG aus Mainhattan.

[@bitluni]

Freut mich dass es dir gefällt :-)

[@larrylange7949]

@@bitluni =o) and good morning., one patreon question of me needs to be answered :)

[@soyuzistrepublic9771]

Can I use a cheaper plastic gear version of the m996r(FS5103B)? I have some so it would be cheaper then buying new m996r motors

[@soyuzistrepublic9771]

Yo you said it needs 3 ball bearings but in the parts you have 4 ball bearing holls? Why?

[@bred8080]

hey i downloaded your 3d model folder and the claws arent visible, what should i do

[@rupaliskitchen2112]

Hello i am from India I didn't found the code file and circuit diagram so please can you provide it to me and also make a video t for the wireless connection

[@ПентаграмШепперд]

to track movements 1/1 precise just use potentiometers)

[@Electromakerio]

Great suggestion!

[@dekutree64]

Do you have any ideas for how to read the wrist twist angle with a potentiometer? I would like to use all mechanical sensors for my project, but I need it to be durable and unobtrusive. Thus far the only good designs I've come up with use IMU sensors.

[@Here_is_Waldo]

@@dekutree64 Why not a gyroscope? Unless I'm misunderstanding what they are for, they seem as though they'd be perfect to detecting the rotation of your arm, far better than an accelerometer would be.

[@dekutree64]

@@Here_is_Waldo Mechanical spinning gyroscopes do indeed track absolute orientation, but they're too bulky. MEMS gyro sensors only detect angular acceleration, so you have to integrate twice to get orientation, which is not accurate at all (drifts constantly).

[@pangeatech8738]

Very cool project. Thanks for sharing.

[@TrucoStep]

what size are the male and female screws? i amb gonna to make a robotic arm with memory of the movement and i will send someone to print some parts

[@khalidalamin8069]

Could you have used some capacitors or filters to remove the jittering

[@Electromakerio]

Great suggestion. Are you planning on recreating the project?

[@tylergoldsmith4884]

Hello I wanted to recreate this project but I couldn't find the 3d print files anywhere

[@Electromakerio]

You can find them here: github.com/bitluni/RobotArm/tree/master/Models

[@alexaizenberg8078]

M3 screws? Length?

[@AnshumanFauzdar]

Okay, This video deserves 1 million views!!

[@bitluni]

Thanks.. I hope it won't drown in the YT noise

[@AnshumanFauzdar]

@@bitluni haha, it wont keep the good work going😊, I will try to spread your videos to my friends

[@johnacsyen]

"Wrong item", so funny. Subscribed.

[@bennedictbyy]

Imagine what this will be in 20 years!

[@Electromakerio]

Its hard to imagine where we will be in 20 years!

[@Skeptic2006]

could you control this arm wirelessly to do simple maneuvers? This + wificam would let you do all sort of remote things. scoop fish food into a tank or the best thing would be to be able to open wet food bags for cats remotely.

[@nrdesign1991]

There is no feedack about applied forces (you could squish anything) and the movements are stilll too jerky.

[@bitluni]

I like the thinking!

[@bitluni]

Let's say there is "visual" feedback :-)

[@redriot2173]

Is there any way to make into a larger system so it has a cleaner setup, I feel that you could enlarge your print to make it look cooler cause biggers better

[@Electromakerio]

Yes this project would look awesome if it was bigger!

[@James-zr8vi]

Now to upscale it and attach four to my back!

[@Electromakerio]

YESSSSS!

[@ramkharwar52]

Which material have u used for 3D printing parts? and can u mention the dimensions of the parts?

[@Electromakerio]

Bitluni used PLA fro this project build.

[@SianaGearz]

METAL GEAR you say? I found Otacon. I am surprised at how well this works. Full body motion capture next?

[@asharharoon6899]

Did you use inverse kinematics for the robot joint angles?

[@Electromakerio]

Yes he did. Are you planning on recreating this project?

[@zolatanaffa87]

Very nice project! Next step: trhowing all that wiring behind the shoulder or connecting to a wifi transmitter!

[@bitluni]

That's in fact what is needed. The I²C wires are lengthwise at their limits. Splitting the code into two parts that are communicating over wifi would be a huge improvement

[@dekutree64]

@@bitluni Yep. Give each sensor module its own battery and wifi transmitter and it will be much more comfortable and less delicate. Use RTIMULib to get absolute orientation of the sensors relative to the earth. Inverse transform each one by its parent's orientation (multiply wrist quaternion by the conjugate of the forearm's quaternion, forearm by conjugate of upper arm, and so on), and convert to euler angles. This will give you precise joint angles regardless of your body orientation.

[@mohamednafea7572]

I cant find the mechanical design downloadable file

[@Electromakerio]

It a the bottom of the project page on electromaker.io!

[@giahieuphan8965]

It haven't a code ???

[@DragonKM82]

Which program do you use for the circuit diagram?

[@bitluni]

EasyEDA

[@crisp4085]

Hey could anyone tell me the aproxamate cost of this?

[@Electromakerio]

About $40. All of the components used can be viewed on the project page here: www.electromaker.io/project/view/robot-arm

[@babylongate]

this guy is german only the german can do such high levels of engineering for fun and do calculate all the math

[@Culturedropout]

Oh - that's awesome! I'm still amazed by the accuracy and low cost of those inertial sensors. But then I grew up with things like mercury tilt switches and potentiometers with weights attached as the cutting edge of motion tracking.

[@bitluni]

...my friends instantly posted me a link to the episode of big bang theory where Howard had a robot arm :-D

[@gr7480]

😂😂😂 you are crazy. Thanks. Very Good video. I like this.😂
