The status quo of industrial robot technology and the trend of development at home and abroad
The development of foreign robotics has several trends in recent years:
1. Industrial robots continue to improve performance (high speed, high precision, high reliability, easy to operate and maintain), while the price of stand-alone equipment continues to decline, the average stand-alone price has dropped from $103,000 in 1991 to $65,000 in 1997. .
2. The mechanical structure is becoming modular and reconfigurable. For example, the servo motor, reducer and detection system in the joint module are integrated in three positions; the joint module and the connecting rod module are used to construct the robot whole machine in a reconfigurable manner; the modular assembly robot products in foreign countries have been asked.
3. The industrial robot control system develops toward the open controller based on PC, which is convenient for standardization and networking. The integration of the device is improved, the control cabinet is compact, and the modular structure is adopted; the reliability and ease of operation of the system are greatly improved. And maintainability.
4. The role of sensors in robots is increasingly important. In addition to traditional sensors such as position, velocity, and acceleration, sensors for assembly and welding also use sensors such as vision and force, while remote-controlled robots use vision, sound, force, and touch. Multi-sensor fusion technology for environmental modeling and decision control; multi-sensor fusion configuration technology has mature applications in product systems.
5. The role of virtual reality technology in robots has evolved from simulations and rehearsals to process control, such as manipulating robots by giving remote robot operators the feeling of being in a remote working environment.
China's industrial robots started from the "seventh five-year" scientific and technological breakthroughs in the 1980s. With the support of the state, through the "seventh five-year" and "eight-five" scientific and technological research, we have basically mastered the design and manufacturing technology and control system of robotic manipulators. Hardware and software design technology, kinematics and trajectory planning technology, produced some key components of robots, developed robots for painting, arc welding, spot welding, assembly, handling, etc. Among them, there are more than 130 sets of painting robots in more than 20 The company's nearly 30 automatic painting production lines (station) have been scaled up, and arc welding robots have been applied to the welding line of automobile manufacturers. However, in general, there is still a certain distance between the level of industrial robot technology and its engineering application in China, such as: reliability is lower than foreign products; robot application engineering starts late, application field is narrow, production line system technology and There is a gap between foreign countries; in terms of application scale, there are about 200 domestic industrial robots installed in China, accounting for about four ten thousandths of the installed bases in the world. The above reasons are mainly due to the lack of formation of the robot industry. At present, the production of robots in China is based on the requirements of users. “One customer, one redesignâ€, with many varieties and specifications, small batch size, low generalization of parts, long lead time and cost. Not low, and the quality and reliability are unstable. Therefore, it is urgent to solve the key technologies in the early stage of industrialization, comprehensively plan products, do a good job in serialization, generalization, and modular design, and actively promote the industrialization process.
