We understand the so-called intelligent robot in a broad sense. The most impressive impression of intelligent robot is a unique "living creature" for self-control. In fact, the main organ of self-control "living thing" is not as delicate and complex as real people.
Intelligent robot has a variety of internal and external information sensors, such as vision, hearing, touch and smell. In addition to receptors, it also has effectors as a means of acting on the surrounding environment. These are muscles, or self-adjusting motors, which move hands, feet, long noses, antennae, etc. Therefore, intelligent robot should have at least three elements: feeling element, reaction factor and thinking element.
Intelligent robot we call this kind of robot self-control robot in order to distinguish it from the robot mentioned above. It is the result of cybernetics, which advocates the fact that life and nonliving purposeful behavior are consistent in many ways. Just as an intelligent robot maker said, robot is a functional description of a system. This kind of system can only be obtained from the growth of living cells in the past. They have become something we can make ourselves.
Intelligent robot can understand human language, use human language to talk with operators, and form a detailed mode of actual situation in its own "consciousness". It can analyze the situation, adjust its actions to meet all the requirements of the operator, draw up the desired actions, and complete these actions in the case of insufficient information and rapid changes in the environment. Of course, as like as two peas in human mind, it is impossible to do so. However, there are still attempts to build some kind of "microcosm" that computers can understand.
