This project structurally optimizes the robotic assistant that serves as pedagogical support to children with and without disabilities. We began studying of different geometries and materials considering certain aspects tecnic and economic that determine by weighting parameters: the form and possible materials for the design of the new structure. After, be defined all the variables and restrictions affecting it during the therapy, thus establishing the structural model and for its analysis used CAD-CAE computational tools based on finite elements it can to observe the possible deformations, material, efforts and safety factor to which would be subjected. By last, the results obtained from the prototype and the possible materials for an immediate, medium and long term future are presented that will improve the robot-patient interaction, helping in the visual, sensory and social therapy and in the general learning of the child.
