Description
Technical Field
The invention relates to a control circuit, in particular to a charging protection control circuit of an intelligent remote control writing robot, and belongs to the technical field of control circuits.
Background
We understand in a broad sense the so-called intelligent robot, which gives the most profound impression of a unique self-controlled "living thing", and in fact, the main organs of this self-controlled "living thing" are not as delicate and complex as the real person.
The intelligent robot is provided with various internal information sensors and external information sensors, such as vision, hearing, touch and smell. In addition to the receptors, it has effectors as means of acting on the surroundings, namely muscles, or self-paced motors, which move hands, feet, long noses, antennae, etc., and it is also known that an intelligent robot has at least three elements: sensory elements, reactive elements and thought elements.
We refer to this robot as an autonomous robot in order to distinguish it from the robots mentioned above. It is the result of the control theory that advocates the fact that the purposeful behaviors of life and non-life are consistent in many respects, as is said by the manufacturer of intelligent robots, which are functional descriptions of systems that were only available in the past as a result of the growth of living cells, and that have now become something we can make themselves.
The intelligent robot can understand human language and converse with the operator by human language, and separately forms an external environment which enables the intelligent robot to live in self consciousness, namely an exhaustive mode of actual conditions. It can analyze the situation that occurs, can adjust its own actions to meet all the requirements set by the operator, can formulate the desired actions, and accomplish them under conditions of insufficient information and rapid environmental changes. Of course, this is impossible to do as our human mind is, however, there are still some attempts to create some kind of "micro-world" that the computer can understand.
