A device called GTGraffiti simulates the fluidity of human hand movements.
In order for a robot to be able to draw in a human style, it must be designed with human features in mind.To do this, the team used motion capture technology to learn how to drawThis strategy allows you to understand how the hand should move in order to make the right strokes.
To do this, the researchers invited two artists to draw the letters of the alphabet in a graffiti style.As each artist painted, they recorded the movements of their hand as well as the movements of a can of paint.This data helps the robot when drawing: it uses the same composition and movements as a human artist.
The team then processed the data toanalyze each movement: how quickly it was performed, on what scale a new stroke was made. In the third stage, the artist's composition is converted into electrical signals. The result is a library of digital symbols that can be programmed for any image size, angle, and combination.
To choose a sequence of strokes, you need to use mathematical equations to create trajectories that the robot should follow.
