The area of cognitive or intelligent robotics is moving from the single robot control and behavior problem to that of controlling multiple robots operating together and even collaborating in dynamic and unstructured environments. This paper introduces the topic and provides a general overview of the current state of the field of modular and multi robotics taking both of these subareas as different representations of the same problem: how to coordinate multiple elements in order to perform useful tasks. The review shows where Hybrid Intelligent Systems could provide key contributions to the advancement of the field.
