My previous project involved a lot of pixel-perfect arc alignments, so I wanted to just work with simple shapes this time around to really focus on the code. A lot of the process was trial-and-error, basing the rest of the body around the robot’s head. Additionally, most of the randomization is set to be a certain proportion relative to the head so that the randomized elements don’t get too out of control and start forming a gray blob instead of communicating a robot.
