Since the first digital electronic computer came out in 1946, the computer has made amazing progress and developed towards high speed, large capacity and low price. 1954, American Deval first put forward the concept of industrial robot and applied for a patent.
The main point of this patent is to control the joints of the robot with the help of servo technology, and teach the robot with hands, so that the robot can record and reproduce actions. This is the so-called teaching and reproducing robot. Almost all existing robots adopt this control method.
As the earliest practical model of robot products, it is 1962 VERSTRAN introduced by AMF Company of the United States and UNIMATE introduced by UNIMATION Company. The control mode of these industrial robots is similar to that of CNC machine tools, but their appearance characteristics are different, and they are mainly composed of humanoid hands and arms.
Robot development stage
The first generation robot: teaching and reproducing robot, 1947. In order to handle and dispose of nuclear fuel, Oak Ridge National Laboratory developed the world's first remote-controlled robot. This kind of robot controls a machine with a degree of freedom through a computer, stores programs and information through teaching, reads information while working, and then gives instructions.
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.
The third generation of robots: intelligent robots, robots invented since the 1990s. This kind of robot is equipped with a variety of sensors, which can carry out complex logical reasoning, judgment and decision-making, and decide its own behavior independently in the ever-changing internal state and external environment.
