The development trend of welding robot（2）

At present, the international robotics community is intensifying scientific research and conducting research on common robot technologies. From the perspective of the development trend of robot technology, welding robots, like other industrial robots, are constantly developing in the direction of intelligence and diversification. It is specifically manifested in eight aspects (which will be divided into two parts 1 and 2 for analysis). The following are four aspects:

1) Robot remote control and monitoring technology Welding operations in high-risk environments such as nuclear radiation, deep water, and toxic environments require remote-controlled robots to replace human work. The characteristic of the development of contemporary remote control robot system is not to pursue full autonomy, but to focus on the human-computer interaction control between the operator and the robot, that is, the remote control plus partial autonomy system constitutes a complete monitoring and control system. Control System. Remotely control the operating system, making intelligent robots go out of the laboratory and into practical use. stage. The "Sojourner" robot launched by the United States to Mars is the most famous example of the successful application of this system. The cooperative control of multiple robots and operators can establish a large-scale robot remote control system through the network, and in the event of a delay, a remote control pre-display can be established.

2) Virtual Robotics: The role of virtual reality technology in robotics has evolved from simulation and drills to process control, such as making the operator of a remote-controlled robot feel like he is manipulating the robot in a remote working environment. Based on multi-sensor, multimedia, virtual reality and telepresence technologies, virtual remote operation and human-computer interaction of robots are realized.
3) Cost-effectiveness of robots: The performance of robots continues to improve (high speed, high precision, high reliability, easy operation and maintenance), while the price of a single machine continues to decline. Due to the rapid development of microelectronics technology and the application of large-scale integrated circuits, the reliability of robot systems has been greatly improved. In the past, the reliability MTBF of the robot system was generally several thousand hours, but now it has reached 50,000 hours, which can meet the needs of any occasion.

4) Multi-agent control technology: This is a new field of robot research. Mainly carry out research on multi-agent group structure, communication and negotiation mechanism between multi-agents, perception and learning methods, modeling and planning, group behavior control, etc.
