This code generates 'polyomino factories' using parallel self-assembly that actuate large swarms of particles using a uniform global, external force with the same effect on each particle. This occurs in a 2D grid world, in which all obstacles and particles are unit squares, and for each actuation, robots move maximally until they collide with an obstacle or another robot.
We present algorithms that, given an arbitrary 2D polyomino (arrangements of unit squares that are connected at edges), design an obstacle layout. When actuated, this layout generates copies of the input 2D structure.
The main file is BuildFactory.m
BUILDFACTORY given a polyomino part, constructs a tile factory that
contains part hoppers for each part, and a factory floor layout so that a
repeated sequence of r,u,l,d constructs a new partXY each iteration until
supplies run out.
partXY: 2D array of the coordinates (rows and columns) of the tiles
numCopies: Number of copies of the partXY to be produced.
IsPossible: true if part can be constructed, false else
factoryLayoutArray: If 'IsPossible' 2D array of obstacles and part hoppers filled with colored tiles.
The factory produces partXY
