RAP (Robotic Action Painter), designed by Leonel Moura (with IdMind) for Museum or long exhibition displays, is completely autonomous painting robot that need very little assistance and maintenance.
RAP creates its own paintings based on an artificial intelligence algorithm, decides when the work is ready and signs in the right bottom corner with its distinctive signature.
The algorithm combines initial randomness, positive feedback and a positive/negative increment of 'color as pheromone' mechanism based on a grid of nine RGB sensors.
