-To form square lattice, we can build upon the previous example. The insight is to notice that, in a square lattice, we can color the nodes forming the lattice with two shades, e.g., red and blue, and then mimic the [[http://www.metafysica.nl/turing/nacl_complex_motif_4.gif|crystal structure of kitchen salt]]. In this structure, if two nodes have different colors, they stay at a distance *D*; if they have the same color, they stay at a distance D*sqrt(2).+To form square lattice, we can build upon the previous example.

-With this idea in mind, the following script divided the robots in two swarms: those with an even id and those with an odd id. Then, using ''neighbors.kin()'' and ''neighbors.nonkin()'', the robots can distinguish which distance to pick and calculate the correct interaction vector.+With this idea in mind, the following script divides the robots in two swarms: those with an even id and those with an odd id.
