Research on modular design for special robots

In order to get a modular robot system with a wider range of application in the field of attack or explosive disposal or scout, this paper proposes a design method for it based on the study of some special robots with the similar function using a bottom-up modular design approach. First, the function structure analysis is applied to an attack robot, an explosives disposal robot and a scout robot separately. Then the module heuristics is used to get the module division. After the module division, the three robots' sharing modules and personal modules can be figured out by comparing the module divisions, which provide the basis for establishment of a special robot module system. The idea of custom-made is introduced to describe the personal modules and establish the relationship between the personal modules and other modules, making efforts to function expansion and development of robot assembly systems.
