Obstacle Navigation
Work by engineer Mieczysław G. Bekker implies that the distribution of irregularities in natural terrains is log-normal; i.e., small obstacles are far more common than larger ones. Thus, obstacle navigation presents a challenge to wheeled locomotion in natural terrains at all size scales. The primary means of obstacle navigation are to go around obstacles, and to go over them.
