Robot is an intelligent machine that can work semi-automatically or fully automatically. Robots can perform tasks such as work or movement through programming and automatic control. Robots have the basic characteristics of perception, decision-making and execution. They can assist or even replace human beings to complete dangerous, arduous and complicated work, improve work efficiency and quality, serve human life, and expand or extend the scope and ability of human activities.
Because robots are very smart, some expensive materials will also be used in research and development. The production cost is expensive, and the price naturally rises a lot. After all, robots can do many things, even replace humans in some fields, and they are more comfortable and worry-free.
Classification of robots
The first generation of robots: 1947 In order to carry and handle nuclear fuel, Oak Ridge National Laboratory developed the world's first remote-controlled robot. 1962, PUMA universal teaching and reproducing robot was successfully developed in the United States, and the multi-degree-of-freedom machine was controlled by computer. By teaching the stored programs and information, we can read the information at work, and then send out instructions to let the robot repeat this action repeatedly according to the results of human teaching at that time.
The second generation robot: perception robot, teaching reproduction robot has no perception of the external environment, and it does not know the magnitude of this operating force, the existence of this workpiece and the quality of welding. Therefore, in the late 1970s, people began to study the second generation of robots, called sensory robots. This robot has human-like senses, such as force, touch, sliding, vision and hearing, and can perceive and identify the shape, size and color of the workpiece through feelings.
