Eye tracking has many comprehensive achievements in the field of human computer interaction. Uses of human eyes as an alternative of hands are an innovative way in the human computer interaction perspective. Many application of autonomous robot control has already been developed, but we developed two different interfaces to control the articulated robot manually. The first of these interfaces is controlled by mouse and the second is controlled by eye tracking. Main focus of our thesis is to facilitate the people with motor disabilities by using their eye as an input instead of a mouse. Eye gaze tracking technique is used to send commands to perform different tasks. Interfaces are divided into different active and inactive regions. Dwell time is a well known technique which is used to execute commands through eye gaze instead of using a mouse. When a user gazes in an active region for a specific dwell time, the command is executed and the robot performs a specific task. When inactive regions are gazed at, there no command execution and no function are performed. The difference between time of performing the task by mouse and Eyetracking is shown to be 40 ms, the mouse being faster. However, a mouse cannot be used for people with motor disabilities, so the Eyetracker in this case has a decisive advantage. Keywords: Eyetracking, Interface, Articulated robot

Faculty of Engineering in collaboration with the National Agricultural and Livestock Investigation Institute is developing a low cost platform capable of dealing with challenges imposed by agricultural activities, specifically, fruit transportation inside fields. In this context, the consequent dissertation focuses on the development of a dynamic model of an all terrain articulated autonomous vehicle to be applied in the aforementioned platform. The study includes the kinematic and dynamic analysis of the vehicle. Once those models are deducted, they are put together against the ones obtained for a biarticulated robot arm without ground fixation. To sum up, results will be adapted for computational simulation which was done via Gazebo, an ambience of the robot operating system ROS. Through this simulations it was possible to determine the model validity for the autonomous operating robotic platform. / Facultad de Ingeniería en conjunto con el Instituto Nacional de Investigación Agropecuaria desarrolla una plataforma móvil de bajo costo capaz de enfrentar los retos impuestos por la actividad agrícola, más específicamente, asistencia en el transporte de fruta. Es en este contexto que el presente trabajo se enfoca en desarrollar un modelo dinámico de un vehículo autónomo articulado todoterreno para ser aplicado en la mencionada plataforma. El estudio comprende el análisis de la cinemática y dinámica del vehículo. Una vez obtenidos los modelos cinemáticos y dinámicos, se compara los mismos con los obtenidos para un brazo biarticulado sin vínculo a tierra. Finalmente se adaptan los resultados para simulación computacional la cual fue realizada utilizando el ambiente Gazebo del sistema operativo robótico ROS. A través de esta simulación se pudo comprobar la validez del modelo desarrollado para la plataforma robótica autónoma en operación.
