improvements for the stepper: remove 3 length beam with 5 length beam adding 2l pin with stop brushes with a 2 length axle. remove the stepper mechanism with a 2l beam. replace with 5l axle with a stop for first and final gear stage replace the cam, remove remaining 2 pieces for improvement, and add 2 1 x 2 beam thins for the stepper for 1 rotation per step.
Great Video! 2nd mechanism: A servo motor is one with feedback to control the position. 3rd: That's a Geneva Drive with an alternative holding mechanism.
Yeah, exactly, I was a bit bothered by calling this a "servo", as I fail to see the control feedback, but I really like the last stepper mechanism you are showing. The typical way to do this with lego is with a larger geneva wheel, but yours is more compact! Very cool!
The second mechanism does pretty much what the LEGO Power Functions Servo motor does, which doesn't have any actual feedback system (at least not readable outside the motor).
Not really a stepper or servo. A servo would have a closed loop so that it could hit a precise angle; it's more than just turning a bit to one side or the other. A stepper would have the ability to move any given number of steps (not continuously going), and it would have a significant holding torque once it reached it's destination. These mechanisms are cool, but this is still just a DC motor with some interesting motion limiting linkages attached
You've not made a servo motor. You've made a motor attached to a two-position actuator. There's no feedback or drive going to the motor for to correct it's position. The stepper motor is much closer, but still not a stepper motor.

2:06 - nice stepper mechanism (very compact)
I can’t even comprehend the god level of thinking that goes into these creations!
Sadly you didn't post it 2 years ago, now I'm addicted to the servo😅😂
for me, he did its been 2 years XD

This wasnt in my recommended... i searched mechanical program and accidentally found this video uploaded 1 hour ago directly clicked
Everytime more sophisticated! Or as we say „abgefahren“ ;-)
Some really cool designs in this vid! Nice work!!
Just when I needed a stepper mechanism...
This is amazing! Well Done!
17800 subs congrats I was here at like 20 subs

You're right, but I wasn't able to find a better name for the stepper... Thanks for pointing it out!
this is just amazing thanks you very much
excellent designs!
Very good !
Can I ask what is it for?
You could for example use it for steering...
@@in1 good, thanks
Can it really be called a servo if you can't set it to arbitrary positions?
👍👍👍
Great designs but the 2nd is better in off roaders without the returning to the middle 👍

I'm gonna use this to turn my m motor into an servo for automatic transmission
Super gg!
"Out of any motor"
So I can use a servo to make a servo?
Yes, I guess
@@in1 awesome. Seems like it's not a waste of parts lol (why are servos so expensive like 60-70 dollars for one???)
@@jjsanimations Power Functions has long time discontinued,i guess that’s why they kinda expensive and rare
ok
most cheap rc cars use a system similar to the one you showed that's bad for the motor to steer
I love you.
I wonder if this is how real servos work? 🤔
No, not really, it's more like a motor connected to a rotation sensor.
Encoder?
with all the stuff you used which includes a motor and lots of pieces you could have easily bought a regular servo motor
Not really, an original power functions servo motor costs about $60
