A random walk was originally proposed by Einstein to model Brownian motion and to demonstrate the existence of atoms and molecules. Such a walker represents an inanimate particle driven by environmental fluctuations. On the other hand, there are many examples of so-called \"persistent random walkers\", including self-propelled particles that are able to move with almost constant speed while randomly changing their direction of motion.
