Using common locomotion principles we set out to make a really small HEXBUG that gave the appearance of being smart. How will it react when it encounters an obstacle? What happens if it gets turned over? The first prototypes of the Nano were inspired by the old vibrating football games. More recent examples of vibrating motion are the BEAM Vibrobots, and then the Bristlebots. Thirty some iterations, a few years, and dozens of designs later the Nano was born. To give just a taste of how much development went into this product, we engineered and rapid prototyped over 150 variations of legs alone.
