I. INTRODUCTION Today mainly used in industries, robotics greatly influences the daily lives of people, allowing humans to focus mainly on the development of mental activities, rather menial service. This way you can make better use of their abilities, whereas other activities are more redundant the post of programmable objects (robots). II. REASONS A. Kit Lego. The Lego Mindstorms NXT is a system of parts that are fit, thus, carry out various combinations. It was originally created by a Danish Ole Kirk Christiansen, made of plastic scale in the 1950s, becoming popular worldwide. The word LEGO is the fusion of two words Leg Godt, which means, play well. B. Autonomous robotic. Autonomous robots are robots that can perform tasks without help or human interaction, and this factor could be of autonomy is measured in the following skills: • Receive information from the environment. • Working for months and years without human interference. • Move from one point AB without human navigation assistance. • Avoid situations that are dangerous to people. • Repair itself without outside help. • Learn and gain new capabilities without outside assistance. • Adjust your actions according to their strategies around. C. Light and Color Color is nothing more than a visual perception. It is caused by the reaction of the photon beam on retinal cells. The color of a material or object can be determined by measuring the frequency of the wave packets, the molecules
