Also known as external control robot. There is no intelligent unit on the robot, only the actuator and the sensing mechanism. It has the ability to process sensing information and realize control and operation by using sensing information (including vision, hearing, touch, proximity, force and infrared, ultrasonic and laser). Controlled by an external computer, the external computer has an intelligent processing unit, which processes all kinds of information collected by the controlled robot, as well as all kinds of postures and trajectories of the robot itself, and then sends out control instructions to direct the robot's actions. At present, robots used in small group competitions in the Robot World Cup belong to this type. Interactive robot

The robot communicates with the operator or programmer through the computer system to control and operate the robot. Although it has some processing and decision-making functions, it can independently realize some functions such as trajectory planning and simple obstacle avoidance, but it is also controlled by the outside world. Autonomous robot

After design and manufacture, the robot can automatically complete various anthropomorphic tasks in various environments without human intervention. Autonomous robots have modules of perception, processing, decision-making, execution and so on, and can move and deal with problems autonomously like autonomous people. Robots used in the medium-sized group competition in the World Cup belong to this type. The most important characteristics of fully autonomous mobile robot are autonomy and adaptability. Autonomy means that it can perform certain tasks completely independently under certain circumstances, without relying on any external control. Adaptability means that it can identify and measure the surrounding objects in real time, adjust its own parameters and action strategies according to the changes of the environment, and respond to emergencies. Interaction is also an important feature of autonomous robots, which can communicate with people, external environment and other robots. Since autonomous mobile robot involves drive control, sensor data fusion, image processing, pattern recognition, neural network and many other aspects, it can comprehensively reflect the level of a country in manufacturing and artificial intelligence. Therefore, many countries attach great importance to the research of autonomous mobile robots. The research of intelligent robots began in the early 1960s. After decades of development, at present, the intelligent robot based on sensory control (also known as the second generation robot) has reached the practical application stage, and the intelligent robot based on knowledge control (also known as autonomous robot or the next generation robot) has made great progress, and many prototypes have been developed.
