Industrial robot technology status and development trends at home and abroad

2019-11-19 16:35:09

Industrial robot is a typical mechatronics digital equipment, with high added value of skills and a wide range of uses. As the supporting skills of advanced manufacturing industries and emerging industries in an information society, it will become increasingly important for future production and social development. Effect. Foreign experts predict that the robot industry is a new large-scale high-skilled industry following cars and computers. According to calculations by the United Nations Economic Commission for Europe (UNECE) and the International Federation of Robotics (IFR), the international robot market has a promising future. Since the second half of the 20th century, the international robot industry has maintained an outstanding momentum of steady growth. In the 1990s, the development speed of robot products accelerated, with an average annual growth rate of about 10%. The growth rate in 2004 reached a record 20%. In the meantime, the growth rate of Asian robots is very outstanding, reaching as high as 43%.

In recent years, the development of foreign robots has the following trends:

I. The functions of industrial robots have been continuously improved (high speed, high precision, easy to operate and maintain), and the price of single machines has continued to decline. The average single machine price has dropped from US $ 103,000 in 1991 to US $ 65,000 in 1997.

Second, the mechanical structure is developed towards modularization and reconfigurability. For example, the three-in-one integration of the servo motor, reducer and detection system in the joint module; the robot machine is restructured by the joint module and the link module;

Third, the industrial robot control system is developed in the direction of an open controller based on a PC, which is convenient for standardization and networking; the integration of devices has increased, the control cabinet has become more sophisticated, and the modular structure has been selected; greatly improving the system's scalability, Ease of operation and maintainability.

Fourth, the effects of sensors in robots are becoming increasingly important. In addition to the traditional position, speed, acceleration and other sensors, the installation and welding robots also use vision, force and other sensors, while remote control robots use vision, sound, force, Tactile and other multi-sensor blending skills are used for environmental modeling and decision-making control; multi-sensor blending configuration skills have been maturely used in production systems.

Fifth, the effect of virtual reality skills in robots has been developed from simulation and preview to process control, such as making a remote robot operator feel like he is in a remote operating environment to manipulate the robot.
