The definition of the robot:
1. robot; automatic control device; remote control device
2. Mechanically rigid people, working like machines

It is the product of advanced integrated cybernetics, mechatronics, computers, materials, and bionics. It has important applications in the fields of industry, medicine, agriculture, construction and even military.
The concept of robots in the world has gradually come to a close. In general, people can accept the idea that robots are machines that rely on their own power and control to achieve various functions. The United Nations Standardization Organization has adopted the definition of robots by the American Robot Society: "a programmable and versatile manipulator; or a specialized system with computer-changeable and programmable actions for performing different tasks." Humans bring many conveniences!
Robot, formerly robo, means slave, the servant of human beings. The vocabulary created by writer Robert.

That is to say, the robot body has a space open chain link mechanism, and the motion pair (rotation pair or moving pair) is often called a joint, and the number of joints is usually the degree of freedom of the robot. According to the difference between the joint configuration type and the motion coordinate form, the robot actuator can be divided into a rectangular coordinate type, a cylindrical coordinate type, a polar coordinate type, and a joint coordinate type. For the purpose of anthropomorphism, the relevant parts of the robot body are often referred to as a base, a waist, an arm, a wrist, a hand (clamp or end effector), and a walking part (for a mobile robot).
Drive unit
It is a mechanism that drives the movement of the actuator, and the robot is operated by means of the power element in accordance with a command signal from the control system. It inputs the electrical signal, and the output is the line and angular displacement. The driving devices used by the robot are mainly electric driving devices, such as stepping motors, servo motors, etc., and hydraulic and pneumatic driving devices are also used.
Testing device
It is to detect the movement and working condition of the robot in real time, and feedback to the control system according to the need. After comparing with the setting information, the actuator is adjusted to ensure that the robot's movement meets the predetermined requirements. The sensors as detection devices can be roughly divided into two categories: one is an internal information sensor for detecting the internal conditions of various parts of the robot, such as the position, velocity, acceleration, etc. of each joint, and using the measured information as a feedback signal. Send to the controller to form a closed loop control. One type is an external information sensor for obtaining information about the robot's work object and the external environment, so that the robot's action can adapt to changes in the external situation, enabling it to achieve higher levels of automation, and even making the robot have some kind of "Feeling", to the intelligent development, such as visual, acoustic and other external sensors give information about the working object, the working environment, using this information to form a large feedback loop, which will greatly improve the working accuracy of the robot.
Control System
One is centralized control, that is, the entire control of the robot is done by a microcomputer. The other is distributed (level) control, that is, multiple microcomputers are used to share the control of the robot. For example, when the upper and lower levels of microcomputers are used to complete the control of the robot, the host is often responsible for system management, communication, and kinematics. And dynamics calculation, and send instruction information to the lower-level microcomputer; as the lower-level slave, each joint corresponds to a CPU, performs interpolation operation and servo control processing, realizes given motion, and feeds back information to the host. According to different job requirements, the control mode of the robot can be divided into point control, continuous track control and force (torque) control.
Classification editing
Born in science fiction, people are full of fantasy about robots. Perhaps it is because of the ambiguity of the definition of robots that it gives people full imagination and space for creation.
Chinese robotics experts start from the application environment and divide robots into two categories, industrial robots and special robots. The so-called industrial robot is a multi-joint robot or a multi-degree-of-freedom robot for the industrial field. Special robots are various advanced robots other than industrial robots for non-manufacturing and serving humans, including: service robots, underwater robots, entertainment robots, military robots, agricultural robots, robotic machines, etc. In special robots, some branches develop rapidly and have independent integration trends, such as service robots, underwater robots, military robots, and micro-manipulation robots. International robotics scholars divide robots into two categories based on the application environment: industrial robots in manufacturing environments and services and humanoid robots in non-manufacturing environments, which is consistent with Chinese classification.
The aerial robot is also called the unmanned machine. In the military robot family, the drone is the most active research activity, the largest technological advancement, the most research and procurement investment, and the most practical experience. For more than 80 years, the development of the world's drones has been basically driven by the United States. Regardless of the level of technology or the type and number of drones, the United States ranks first in the world.
Housework
Can help people take care of their lives and do simple housework.
Operational type
Can be automatically controlled, reprogrammable, versatile, with several degrees of freedom, can be fixed or moved for use in related automation systems.
Programmed
The robot's mechanical actions are sequentially controlled in advance by the required sequence and conditions.
CNC type
It is not necessary to operate the robot, and the robot is taught by numerical values, language, etc., and the robot performs work based on the information after teaching.
Search and rescue
After a major disaster, you can enter the ruins that people can't enter, use infrared to scan the scenes in the ruins, and send the information to the search and rescue personnel outside.
Teaching reproduction type
By guiding or otherwise, the robot is first taught to move and the work program is input, and the robot automatically repeats the work.
Sensory control
The information acquired by the sensor is used to control the motion of the robot.
Adaptive control
Can adapt to changes in the environment and control its own actions.
Learning control
The experience of “experiencing†work has a certain learning function and the experience of “learning†is used in the work.
intelligent
A robot that uses artificial intelligence to determine its actions.
Competency evaluation editor
The evaluation criteria of robot ability include: intelligence, refers to feeling and perception, including memory, operation, comparison, identification, judgment, decision, learning and logical reasoning; function, refers to flexibility, versatility or space possession; physical energy, Finger force, speed, reliability, combination and life. Therefore, it can be said that the robot is a practical space running tool with biological functions, which can replace human beings to complete some dangerous or difficult labor, tasks and the like.
