This is the second video of yours that I've watched. You are doing some great engineering and then bring it to life. I love this stuff. That's why I'm now *SUBSCRIBED!*
appreciate it! thanks for the support!
Ditto!
Make a robot arm of these! The "community robot arm" projekt can be a starting point.
I’ll check that out
Nice job! I see an entire functional exoskeleton in your future!
the end of this video explains a lot about how you bring Ideas to life, man I like your creations 1 million thumbs up to you
man the rick roll at the end
Great job! Would love to see you make something using those servos!
That's the plan. I'm thinking of a Rubix cube solver.
I’m so glad I kept going after you said “Thanks for watching”.
Great work, on my project list now
WOW. I love it. Thanks so much. I found you on Instructables. Great content!
Thanks!
You're amazing! I would love to see you explore the idea of miniature 3d printed servos like the 3d printed actuator you made.
I want to make something similar for my robotic hand and its joints because I don't like the idea of using cables or string to move fingers.
Awesome! Loved the torque test with your fingers 😂
the device is used until today, it seems to be an invention of the 1930s. "Selsyn" (from English self-synchronizing) is an induction machine of a synchronous communication system.
Love this. great design.
thanks
Its ment for miniature sail ships like the IOM Sailing Netherlands, they build it themself. (one meter class)
Took me way too long but I finally identified the music at the end. It's from the Wii, from the Mii channel I think.
Correct! A treasure from my childhood.
This moment you smashing bearings with a hammer .... ughhh this hurt my soul xD
LOL 😂 I don’t have a vise so a hammer will have to do
Great work. It's a really nice and smooth one with good performance
Thanks!
well, that's just a remionder that u can be rick rolled by any video
nice..
You're my hero!
Hello Brother. excellent work. can you help me with the second encoder? I would like to control the servo just like you did in the video. with the position of the lever.
I'll be subscriber 743, with hopefully more people finding this channel too
let's hope. thanks for the sub!
Amazing
Mashaallah! Great job, brother.
Thank you sir for sharing amazing knowlages with us. i amtrying to make same servo as you made but oniy difference is i use a potentiomer to get a position so please can you guide me to do this . please help me.
Well done! I am making my own servos too! But I also make a custom PCB for it with an encoder, mc, driver, and current sensor. What kind of control system do you use? Is it PID or something else?
great job and video. I have tried this in the past with much smaller motors but could never fix the overshooting and oscillations. That too i was using the PID library. How did you fix the issue of oscillations and get it to stop on exact position? Also how do you stop exactly at 359 degrees and dont get it overshoot and go back to zero and ultimately keep on spinning and never stop as it never achieves the value?
It all comes down to tuning. If you used a PID algorithm and you still got over shoot then it hasn’t been tuned properly. I find that starting with the proportional term and setting the other terms to zero allows you to get an effective servo. In fact, that’s what I did in this project. There is only a proportional term. It’s just tuned properly so it works pretty well on its own. To get it to continually keep moving I simply continually change the setpoint of the PID algorithm.
Torque measurement using a scale??? I'm also wondering how this would compare against a closed loop stepper motor ...
Did you use 100% infill for the 3D printing?
Thnx
Awesome!
Add 5 more in series and puppeteer the robot arm!
That's a great idea! I'll have to try that sometime in the future.
Awesome.
Perfect !!!💯💢💥💫
First off, nice project. How do you calibrate that encoder? I am assuming it is of the hall effect type, and you are using what looks like a standard button magnet thickness polarized. How do you set say 0 degrees? and does it remember that? or do you assume 0 degrees on boot? Would be really cool if you could use a attiny or similar installed internally and make it so that it accepts input like any standard servo (pwm).
Also, I would love to see this project done with a herringbone gearset
The encoder I’m using is an absolute encoder so it has a range of 0 - 359 degrees. To calibrate it I wrote code that offsets all the values. Say the 60 degree position really needs to be the 0 degree position, all of the values move up 60 degrees so that the 60 degree position is now the 0 degree position. And yes, it remembers this every time every time. I plan on experimenting with gear sets in the future.
@@AaedMusa can’t wait for the follow up video :)
Can you use this instead of a stepper motor in a RepRap 3d printable 3d printer?
Subbed
torque test?
niiiiice😍
Build a sun tracker
Can this be controlled using a PCA9685 16 Channel 12 Bit PWM - Servo Motor Driver ?
No. That only works with servos, these are dc motors.
I love your videos! I am wondering if the encoder/magnet would work with a nema17 in the same way?
Yep, it sure does. I've seen many people use an AS5600 encoder with a stepper motor.
Can you please tell what's the torque achieved from the new servomotor?
I didnt do any torque tests.
like sail winch i ment
Oh ok. I’m not sure what kind of torque is needed for that but it seems doable. One thing I don’t know is if it’s better to sail winching yourself or having a machine do it. It may be better and safer for the human to winch, but again, I have no experience sailing so I don’t know.
How's the backlash on this?
Not great
could you build a servo for sailing?
Like an actual boat? I haven’t the slightest clue how sailing works. Would this act to replace the human operator?
Looks like in the real robot apocalypse they will all be made of plastic
Share the coding side of this project, is it a simple pid?
Yes it uses a PID algorithm. You can find the code and my documentation in the link in the description.
@@AaedMusa Sir you have the capability, so I am going to leave this comment here. Could you in theory,
use the current feedback from the motor driver(bts 7960 has built in current feedback) with the encoder implement to combination of feedforward and feedback control? something like - ruclips.net/video/FW_ay7K4jPE/видео.html
@@sammflynn6751 yes that seems possible
@@AaedMusa sir I humbly request please consider this an idea for a future video
Why did the voice suprised me ?
How so?
@@AaedMusa thats my question smart ass
@@OneHappyCrazyPerson I can’t answer how my voice surprised you.
