I am fairly new to arduinos and stepper motors but want to make a simple robotic arm where each of 3 motors is controlled by a separate potentiometer if possible. I would just like to know what components I would need other than an arduino, stepper motors, potentiometers, a power supply of some sort and maybe a stepper motor driver? It doesn’t have to be too specific I would just like a rough idea of what I would need to do this.
Thank you.
There's a CNC shield that you can get for an Arduino UNO that controls 3 stepper motors.
It's usually used with a specific sketch that interprets g-code generated by various 3D design packages.
I think it might be expandable to 4 channels but you would need to check.
Giving your background I'd suggest to use RC-servos, 50kg types go by ~ 15 bucks on aliexpress.
Surely you can trawl up a complete robot arm kit?? Everything you need, all in one box.
As well as the motors & electronics, you are going to need some plastic/metalwork to create the physical structure of the arm as well as all the various nuts & bolts etc.
That's a big project involving quite a lot of design work.
A quick search for "arduino robot arm kit" showed quite a few kits are available. I would suggest a kit as that would, hopefully, include all the parts you need along with the suitably spec'd motors for the arm.
Of course you could design it all from scratch but you could likely spend ages simply sourcing parts.
As an update I’d have a 3d printer and have some experience with 3d modeling. although i will look into kits and rc servos. thank you.
