Draw Robot program

I want to use a drawing robot, consisting of 2 servos, arduino and bluetooth HC-05, to create a program on a smartphone that sends the drawings from mine smartphone to the drawing robot, for example png extensions or .........
Can someone help me with that or has a message already been written about it, I can not find it anywhere
Thanks in advance

You might start here for ideas on how others control drawing robots using arduino. https://www.google.com/search?q=arduino+drawing+robot&rlz=1C1CHBF_enUS887US887&oq=arduino+drawing+robot&aqs=chrome..69i57.6983j0j7&sourceid=chrome&ie=UTF-8 I don't believe there is a tutorial discussing exactly what you said you would like to do Erwin but there might be something similar using drawings.
