Ibis Hotels chain is installing the robotic artists in their hotels in Berlin, Paris and London.
The hotels are also seeking around 40 participants who would want robots to paint them while they sleep.
Special mattresses which are covered in thin grids, measuring heat, pressure and sound have been created to aid the robot, the Daily Mail reported.
As the body moves, thin sensors will monitor its heat and send the data to the robot.
The robot receives the data, and plots your movements on the canvas, creating a beautiful design out of your sleep lines.
A data cable connects the robot to your bed, and the robot will use its ample paint supply to make your portrait.
The portrait will depend on an individual's sleeping pattern. A deep sleeper may encourage straight and simple lines, whereas if somebody thrashes around all night, it might be a little abstract.
