I need somebody to find the information on robots that are able to draw pictures. What is the pricing, what are the most popular one's. I need price range and their abilities to be written in the table. Also, I need the ones that I can buy and possess right now, not the one's that are just in development or too far from US, so I can't buy them. I need a full research on the market of this kind of robots with any info that can be useful for me (likewhat is the average speed of robot, how large can the picture can be, whether a robot can switch colors or width of the way they draw e.t.c) The robots must be able to draw on a real paper.
