An intelligent mechanism is a traditional mechanism that incorporates within it, elements of intelligence both at the design stage. Thepurpose is to increase the operational envelop of the original meachanism so that it can now exhibit some from of learning, adapting, or responding to changes in the environment or new operating conditions. Since mechanisms are usually designed for repetitive motions, the application of intelligence that makes specific use of repetitive characteristics will markedly improve the functionality of the mechanisms. This is particularly true if the mechanisms have been incorporated with such intelligence at the early stages of design. This article develops the concept of an intelligent mechanism through the application of Iterative Learning Control and Repetitive Control methodologies to several traditional mechanisms. These range from the simple slider-crank and four-bar linkage to timing belts.
