The development of new technologies in urban automation has increasingly intensified in recent decades. Among the research initiatives, there is the study and design of service robots for home tasks, such as: cleaning floors, windows, and pools. The technology used in these robots depends on specific resources and great investments, and consequently, the price is expensive, restricting the use for people with high purchasing power. Thus, it is important to study means to manufacture robots with better cost-benefit, looking for to develop mechanisms that can reduce the production costs, and then a greater number of people can use such technology. Therefore, the objective of this work is to develop an underwater cleaning robot, which can be used for cleaning pools. Several aspects of the project, a model created by means of computational methods, and some analyses of the robot structure will be presented.

The chapter describes the stages of an autonomous mobile robot project, in this case, an underwater cleaning robot. First, the authors analyze the products already available for costumers, mainly focusing on the tasks they can perform (instead of the systems they use), in order to define the requirements of their project. Then, they build some models, based in the literature available. Based on them, the authors dimension the parts and systems by evaluating the results of these models. Finally, the authors use all information gathered to create a prototype, modeled with a CAE system.
