Robot 1: Draw
This is P5, the Processing Robot. There are 10 different programs
to draw and animate him in the book—each one explores
a different programming idea. P5’s design was inspired by Sputnik
I (1957), Shakey from the Stanford Research Institute
(1966–1972), the fighter drone in David Lynch’s Dune (1984),
and HAL 9000 from 2001: A Space Odyssey (1968), among
other robot favorites.
The first robot program uses the drawing functions introduced
in this chapter. The parameters to the fill() and stroke() functions
set the gray values. The line(), ellipse(), and rect()
functions define the shapes that create the robot’s neck, antennae,
body, and head. To get more familiar with the functions, run
the program and change the values to redesign the robot:
size(720, 480);
strokeWeight(2);
background(0, 153, 204);
ellipseMode(RADIUS);
// Blue background
// Neck
stroke(255);
line(266, 257, 266, 162);
// Set stroke to white
// Left
