Interpreting The Eight Trends Of Welding Robot Development
- Oct 25, 2017 -

At present, the international robot community is increasing the intensity of scientific research, robot common technology research. From the development trend of robot technology, welding robots and other industrial robots, as to the direction of intelligent and diversified development. Specifically, the development trend of the robot in the following aspects:

1 robot operation mechanism

Through the use of modern design methods such as finite element analysis, modal analysis and simulation design, the optimal design of robot operation mechanism is realized. Explore new high-strength lightweight materials to further increase the load / weight ratio. Institutions toward the modular, refactorable direction. For example, the joint module in the servo motor, reducer, detection system three integration; by the joint module, connecting rod module with a reorganization of the structure of the robot machine; abroad has been modular assembly robot products to the city. The structure of the robot is more intelligent, the control system is getting smaller and smaller, the two are moving in the direction of integration. The use of parallel technology, the use of robot technology to achieve high-precision measurement and processing, which is the robot technology to the expansion of CNC technology for the future to achieve the integration of robotics and CNC technology laid the foundation.

2 Robot control system

Focusing on open, modular control system. To the PC-based open controller direction, easy to standardize, network; device integration increased, the control cabinet is small, and the use of modular structure; greatly improve the system reliability, ease of operation and maintainability The The performance of the control system is further enhanced by the development of a 6-axis robot that has been controlled by the past to now capable of controlling 21-axis or even 27-axis, and has achieved software servo and full digital control. Man-machine interface is more friendly, language, graphical programming interface is being developed. The standardization and network of robot controller and the network controller based on PC have become the research hotspot. Programming technology In addition to further improve the operability of online programming, the practical use of offline programming will become the focus of research, in some areas of offline programming has been practical.

3 robot sensing technology

In addition to the traditional position, speed, acceleration and other sensors, the assembly, welding robot also uses a laser sensor, Welding Robot visual sensors and force sensors, and to achieve the automatic tracking of weld and automated production line objects Automatic positioning and precision assembly operations, etc., greatly improving the robot's performance and adaptability to the environment. Remote control robot is the use of vision, sound, force, touch and other multi-sensor fusion technology for environmental modeling and decision control. To further improve the intelligence and adaptability of robots, the use of multiple sensors is the key to solving their problems. The research hotspot lies in the effective multi-sensor fusion algorithm, especially in the non-linear and non-stationary, non-normal distribution of the multi-sensor fusion algorithm. Another problem is the practical use of the sensing system.

4 network communication function

The latest robot controller has been implemented with Canbus, Profibus bus and some of the network connection, so that the robot from the past to the application of independent applications to the network a big step forward, but also to the robot from the past special equipment to the development of standardized equipment.

5 robot remote control and monitoring technology

In some high-risk environments such as nuclear radiation, deep water, toxic and other high-risk environment, the need for remote control of the robot instead of people to work. The development of contemporary remote control robot system is not the pursuit of full autonomy system, but is committed to the operator and the robot human-computer interaction control, that is, remote control plus local autonomous system constitutes a complete monitoring remote control operating system, intelligent robot out of the laboratory into practical stage. Welding Robot Multi-robot and operator coordination between the control network can be established through a wide range of robot remote control system, in the case of delay, the establishment of pre-display for remote control and so on.

Virtual Reality Technology

The role of virtual reality technology in robots has evolved from simulation, rehearsal to the use of process control, such as the use of remote control robot operators in the remote operating environment to manipulate the robot. Based on multi-sensor, multimedia and virtual reality and telepresence technology to achieve the robot's virtual teleoperation and human-computer interaction

7 Robot cost performance

Robot performance continues to improve (high speed, Welding Robot high precision, high reliability, ease of operation and maintenance), and stand-alone prices continue to decline. Due to the rapid development of microelectronics technology and the application of large scale integrated circuits, the reliability of the robot system has been greatly improved. In the past, the reliability of the robot system MTBF is generally thousands of hours, and now has reached 50,000 hours, to meet the needs of any occasion.

More than 8 agents control technology

This is a new field of robot research. Mainly on the multi-agent group architecture, mutual communication and consultation mechanism, Welding Robot perception and learning methods, modeling and planning, group behavior control and other aspects of research.
