The authors argue that intelligence is necessary in robots used for rehabilitation in order to reduce the amount of mental activity needed by the user of these robots. With this in mind, the areas of research relevant to imparting robotic systems with the capability of assuming a more intelligent role are identified. The authors describe their implementation of functionalities such as fuzzy command interpretation, object recognition, face tracking, and task planning and learning, which are part of the ISAC, an intelligent system designed to feed individuals with physical disabilities.>
