Since 1980s, people have called the system with the ability of feeling, thinking, decision-making and action as intelligent robot. If the robot has cognitive ability, learning ability, thinking ability and the ability to adapt to the environment, it belongs to intelligent robot
1) Sports part
Intelligent robot needs a trackless mobile mechanism to adapt to different geographical environments such as flat ground, steps, walls, stairs, ramps, etc. Their functions can be completed by means of wheel, track, bracket, suction cup, air cushion and other moving mechanisms. In the process of motion, the real-time control of the moving mechanism should be carried out, which includes not only position control, but also strength control, position and strength mixed control, expansion rate control and so on. The moving part includes walking mechanism, manipulator and claw.
2) Intelligent part
The intelligent part of intelligent robot includes cognitive ability, learning ability, thinking ability and decision-making ability. The intelligent part thinks what kind of action to use according to the information obtained from sensory elements. The intelligent part of intelligent robot is the key of the three parts, and it is also the necessary part for people to give robot. The intelligent part includes the intellectual activities of judgment, logical analysis and understanding. These intellectual activities are essentially a process of information processing, and computers are the main means to complete this process.
3) Sensory part
The sensory part includes non-contact sensors that can sense vision, proximity, distance and so on, and contact sensors that can sense force, pressure sense, touch and so on, which are used to recognize the state of the surrounding environment. In essence, the sensory part is equivalent to the eyes, nose and ears of human beings. Their functions can be realized by using electromechanical components such as cameras, image sensors, ultrasonic transducers, lasers, conductive rubber, piezoelectric components, pneumatic components, travel switches, etc.
Scientists are developing more and more advanced intelligent robots, mainly based on the human body as the reference object. Naturally, the first prerequisite is to have a very simulated human appearance. In this respect, Japan should be relatively advanced. When the perfect artificial skin, artificial hair, artificial facial features, etc. are properly covered on the robot body, standing there with the perfect human orthodox gesture. In this way, at first glance from a distance, you will really mistakenly think that it is a big living man. When you get closer, you will find that it is just a robot.
The actions of robots usually imitate the actions of human beings, and the actions that human beings can do are extremely diverse. Various gestures such as waving, shaking hands, walking, running, jumping, etc. are the common actions of human beings. However, although modern intelligent robots can imitate some human actions, they are relatively rigid or slow. In the future, robots will use more flexible human like joints and artificial muscles to make their actions more like human beings, so as to imitate all human actions and even make them more realistic. The robot can make some movements that ordinary people are difficult to do, such as flat somersault, handstand and so on.
For the future robot, the degree of simulation is likely to reach. Even if you look at its exterior close at hand, you will only regard it as a human being, and it is difficult to distinguish it from a robot. This situation is just like that in the American sci-fi blockbuster terminator, the robot character modeling has extremely perfect human appearance.
