+GetLoFi I'm planning to make a tiny robotic arm. Something like you would see on a backhoe, but maybe with a clamp on the end instead of a bucket. I'm going to have it pick up BBs and put them into a "marble machine" type contraption. Maybe.
When I saw the screws and nuts, that's when I said, "yep I did something like this with this robotic claw I've made". What I did was actually solder the screw to the shaft. I also added a little oil and purposefully left a gap between the base of the screw and the nut. I found that it works better that way.
Hey Clayton. This is one of the first robotic claws I've made. It's really old and the one I had before worked way better. Unfortunately, I took it apart. I wish I can show you a better one. I did add something else I was working on. I was testing an old motor I've altered. It has a gas line running through it and it allows flames to shoot out of the drill. I can make the flames higher, but with my two jobs and having to relocate most of the time, improvements have been slow lately. th-cam.com/video/VYhmYw2Rf8g/w-d-xo.html
The motors are powered by an SN754410 quad half bridge. The SN755410 is controlled via a PIC12F675 microcontroller from a serial port. It could also be done using the pins on a raspberry pi. I have a website, www.PyPins.com, where I am trying to document the process. All the software is up-to-date, but the documentation is not at this point.
your video made me to try my mini project possible...thanks for the video....i'm trying to use Arduino Nano with L298N drive...are these motors gonna work?
Yes. The SN754410 is a direct replacement for the L298N, so that should work fine. Just be careful with the voltage on these little motors. They have low resistance and can get hot very fast. I turn them off (set all pins to low) when they are not moving. This gives them time to cool down.
PhotoSlash - Maybe. They are running as fast as possible at 5v. The motors will skip if the steps are faster. But they might go faster at 12v. At 12v you will need current limiters or they will probably overheat.
PhotoSlash - You can make a make it go faster without adding more power, by playing around with the positioning of the pivot points and/or use a courser threaded rod and nut. Either case, will decrease the amount of pull/push force the assembly can provide.
Any stepper driver will workb but... This is running from a Linux PC, controlled by a Python script, over a USB serial adapter, to a pic12f675 and an SN754410 quad half bridge per each channel. Basically I'm sending the pin-out states serially on a master-slave network.
Watched all your videos this evening. Enjoyed them all.
+notionSunday I'm glad you did.
Brilliant! Thanks for the inspiration. Your projects are amazing
+GetLoFi Thanks.
+Clayton Darwin are you designing a little Delta drawing machine with those actuators then?

Guy, you are great and helpful. Million thanks !
This is exactlly what I am looking for, thanks for sharing!
when watching these great videos I have to subscribe, Thank you for sharing these great ideas with us.
+Magdi Nakhla I'm glad you like them.
Haha that's awesome! Maybe I'll "borrow" this design for my next robot arm!
This is friggin awesome Clayton and potentially the answer I have been looking for - You have a sub! :)
This is 8 years late but..... PURE G.E.N.I.U.S.
Awesome sire. That is soooo cool. Very well done. More More More.......
+Raymond Earle Thanks Bro.
Would you happen to have a diagram on how to wire the motor. I really like what your doing. I would like to see it when you are done.
It is s standard 4-wire bipolar stepper motor. Requires a controller of some sort. I have some vids of a robotic arm I made with several of them.
Brilliant because it's so simple. If you had eight of those arms you would have a spider robot....
Love that. I'm inspired.
Very cool cool. I would use a two part epoxy
Yep. I use epoxy for wires on larger motors, but these are so small.
excellent Idea!
👍
Very cool! Do you have a video of the finished arm? Thanks!
Anthony Castronovo - Thanks. And yes, there are a couple. Check out my channel and look at the playlist.
Not making fun or anything cause i do it, but i had to laugh at 2mm screw about a inch long ...
I like your idea
Thanks.
disculpa donde conseguiste esos motores o de que eran?
En ebay. Son de China.
thats nice and smooth. off to make my own!
Lou Ciamillo - Send me a link when you finish.
Clayton Darwin will do. It's part of a much larger project that I want to finish before Christmas. It will all be on my channel.
Lou Ciamillo - Cool. Will subscribe to your channel.
Much appreciated!

Please post a video so we can check it out.

Cool. I may do something similar to that on my next arm.
and i would like to know what circuits you used to control those stepper motors.
The motors are powered by an SN754410 quad half bridge. The SN755410 is controlled via a PIC12F675 microcontroller from a serial port. It could also be done using the pins on a raspberry pi.

Sir, this is exactly what i was looking for, but i need more speed... can they go faster?

mtktm - Yes. This is another good option.
where can I get the actuators Sir?
I bought the motors and screws on eBay.
Cool th
Thank you
how match can it lift
Well, check out my other videos. They can lift a plotter pen under spring pressure. They can lift BBs using an arm. But not much, that's true.
"much", please!
If you have not already, watch the Teaser of the movie Terminator 2.
Teaser not trailer.
It has your "arm" mechanism in there.
Nice.
Just don't start WW III...
I'll be back.
You'll win the Darwin Award if you do..
cool (Y)
Thanks.
Can you make me 2 I'm working on a project I'd definitely compensate you
Search for "linear servo" on ebay. That might do what you need.
@@ClaytonDarwin I appreciate the help if you ever change your mind about making 2 I'd definitely be grateful 🙏
The ones I made were too low power to be reliable.
@@ClaytonDarwin it's for a small truck design
Thx so much for the help
If you would disclose how you are driving the stepper that would make your information actually "cool".
Any stepper driver will workb but... This is running from a Linux PC, controlled by a Python script, over a USB serial adapter, to a pic12f675 and an SN754410 quad half bridge per each channel. Basically I'm sending the pin-out states serially on a master-slave network.
a quick google search for drivers would be "cool" on your part.
