Essay Ciência sem Fronteiras - Study Objectives (Mayday!)

Olá amigos, preciso muito da ajuda de vocês!
Estou escrevendo minha essay para o processo do CSF e preciso muito de opiniões, vejam o que vocês acham?
A princípio havia escrito uma essay que contava mais sobre minha história acadêmica, no entanto, descobri que essa essay deve ser objetiva e se basear em meus objetivos futuros de estudo. Não sei se consegui cumprir com o objetivo.
Agradeço imensamente.

I am currently studying electrical engineering with a full scholarship support at Centro Universitario da FEI, one of the best engineer schools in Brazil. The university is focused in the whole human development improving the student’s abilities to solve problems through a quality technical formation.
Nevertheless I am looking for an opportunity to study in USA to complement my undergraduate course with new perspectives and the possibility to apply important subjects that are essential to my career, but I am not able to do in a graduation course in Brazil.
My principal focuses of study are robots, especially about artificial intelligence (AI) and how it is applicable to the machines. My long term aim is to dominate some methods of Computational intelligence and other theories used in the creation of the abstraction level of the robots permitting them to evaluate situations from many contexts to accomplish different tasks efficiently.
There are many tools used in AI, including mathematical optimization, logic, methods based on probability and others. In this way, some background are required to understand the basic concepts of the robotics’ and it’s tools, subjects such as Machine Learning, Statistical Techniques in Robotics, Embedded Systems and Embedded Control Systems are some topics that I should dominate.
I have been in a part time project of the robotic laboratory of the university and I am working in an undergraduate research mentorship program (URMP) where I am creating a ball interception system used by the RoboFEI robots playing in the RoboCup Small Size League. I would like to apply the learned techniques into this project and improve the robots skills to communicate with each other.
Unfortunately, these subjects that I am interested are not available at my university hindering me to advance in my researches, however many universities in the United States have the best courses involving Robotics with qualified professionals and teachers that are ready to provide me more in-depth learning and advanced training so that I will have the expertise I need inside and outside the academic world.
In conclusion, an opportunity to study abroad is fundamental to my future perspectives, new practical and technical experiences are going to provide me more confidence, preparing me to be involved in professional projects, creating new technologies with know-how and responsibility, furthermore this chance is going to yield me wisdom and maturity to return to Brazil with different points of view and ready to finish my graduation course and start a new life as an engineer.
