# Need advice regarding servo and stepper motor projects

I have a pair of SG90 servos lying around, so I thought of buying two more and build a robotic arm or biped. But later I realized that I don't have access to a 3D printer or printed parts. So I planned to do something with stepper motors but cannot find anything interesting in the internet. I need advice regarding projects involving servos or stepper motors.

I am going to purchase a pair of these:

Welcome to AAC!
Surely you can build a robotic device without needing access to a 3D printer? Improvise with rod, tube, sheet, bearings, whatever, available from any good model shop, hardware shop or builders' supplier. A punk robot .

With a little bit of work, you can modify a desk lamp frame to make a robot arm. A 3D printer is not needed but can make it easier in places if you are like me and not real good at mechanical things.
Here is one...
It can be a good starting point for ideas.
And of course, you can always build a 3D printer. There are many designs for small ones made from junk box parts on the net. That will use some steppers

You can often pick up old printer/scanners for nothing and a couple of these and maybe a CD player supply the motors and mechanics needed.

"And of course, you can always build a 3D printer."

And you can set up a factory to build your own stepper motors.

Another good source for DIY'ers new to motion control is the CNCzone.
