Hello,
I'm thinking about doing a project using the arduino and a sensor I just don't know what sensor I can use to read the line like this in the links of the videos below.

I need a sensor to be connected to the arduino reading the drawing line then the arduino will send the information of the line that was read to one motor on the X axis and another one on the Y axis to follow the line.
Basically it will work like a robo following of line so it must move the axes x and y with smooth movements.
