This research is focused on developing a robotic painting
system for artistic and graphic applications by means of an anthropomorphic
robot equipped with an airbrush. Firstly, we introduce a mathematical
colour spray model, based on a radially symmetric Gaussian
distribution of colour intensity within the spray cone. Then, we present
an experimental characterization of colour intensity in a spot, by varying
the distance between airbrush and target surface and the spraying time.
The experimental results of this pilot study validate the paint intensity
model and provide the basis for further investigations.
