I have one like this.



Wow.  :-+

I was asking about making robots after finding a bag with SG90 9g servo motors just like yours.  Mine look very fragile, all plastic, including the gears.  Not very precise either, the gearbox has a lot of backlash.  Even if I disregard the backlash, they still have bad repeatability.  For the same control signal, when going back and forth, the resting angle is almost never the same.  :-//
At least they were cheap, $1.1/pcs from Aliexpress.

Does your motors have enough force to lift the robot legs, or is it walking by dragging the legs?

Yes, I broke one servo by applying force. But there is no backlash, everything works precisely.
There is a video on YouTube of how it works.

Home improvement, usually consists of me  buying yet more power tools for one off jobs...  :-DD

I'm also quite into 3D printing.
