Oscar Alfredo Zatarain Pedrero is a student of Mathematics and Mechatronics engineering. His works focus especially on efficient control of robotics arms, trajectory methods as well as kinematics. He is interested in methods that can be applied in a short time of execution and also, with great accuracy. He thinks that implementing methods with a short time of execution and great accuracy in the results, great applications to help people can be developed. In fact, some of his researches are about applications with methods that are quickly applied to control robotics arms that help physically disabled people and using number theory to improve the characteristics of his methods proposed.
