iBEAM robotics is a style of robotics that primarily uses simple analog circuits, such as comparators, instead of a microprocessor in order to produce an unusually simple design. While not as flexible as microprocessor based robotics, BEAM robotics can be robust and efficient in performing the task for which it was designed. Robots that use both analog and microprocessor electronics are known as “mutants”. BEAM robots may use a set of the analog circuits, mimicking biological neurons, to facilitate the robot’s response to its working environment. The word “ BEAM” in BEAM robo tics is an acronym for Biology, Electronics, Aesthetics, and Mechanics.
