The future world must be highly integrated with the information of its own equipment, and the production efficiency will be greatly improved. In recent years, the world economy has been growing at a slow pace. In order to improve the production efficiency of their own manufacturing industries, countries have taken this opportunity to focus on the robot industry and intend to seize the commanding heights of manufacturing intelligence. Germany proposed the " Industry 4.0 " revitalization plan, and the United States has put forward the "Advanced Manufacturing Strategic Plan". The overall level of China's manufacturing industry still has a certain gap compared with developed countries, but China also hopes to improve the overall manufacturing industry. At the level, in 2015, “ Made in China 2025 †was proposed and the plan was raised to the national plan level.
As an important part of manufacturing equipment, robots play an important role in improving the production efficiency of manufacturing. Robots are becoming more and more widely used in industry, and their status is becoming more and more important. As an important part of the robot, the sensor provides the intelligence level of the sensor, which helps to improve the automation and intelligence of the robot. The communication between the robot and external information is performed by sensors. The sensor can not only sense its working state, but also measure the determined physical quantity, and convert the corresponding signal, or execute the corresponding device.
Sensors used on robots today include tilt sensors (or tilt modules), tactile sensors, force sensors, proximity sensors, vision sensors, ultrasonic sensors, and hearing sensors. Can achieve more complicated work, and maximize the working condition of the robot. In order to achieve autonomy in complex, dynamic and uncertain environments, researchers in various countries have gradually combined visual, auditory, embossing, thermal sensing, and force sensors to form a sensing system to provide more detailed The external environment information, in turn, enables the robot to respond to changes in the external environment in real time, accurately and flexibly.
For example, torque sensors in industrial automation measure power and time in all six degrees of freedom. Equipped with a robot control interface, the connection is greatly simplified. The high-precision sensor operates at 8000 Hz and follows five common industrial communication protocols (Ethernet, DeviceNet, Ethernet/IP, Profinet, CAN-Bus) for remote control via LAN and unique interface compatibility. The web interface is configured. It can be applied to product testing, robot assembly, processing tasks such as grinding and polishing, robotic surgery, and other areas such as rehabilitation and neurology. The sensor also supports a highly dynamic concept of control, so it can be used to automate complex assembly, machining and tasks that were previously done manually or with complex special machines. There is also a tilt sensor that measures the current motion posture in real time to ensure the accuracy of the action.
Although modern society has increased investment in the research and development of robots, there are still many problems to solve and deal with. It is still difficult to integrate multiple sensor information systems, and many aspects still lack theoretical basis. The ideal goal of multi-sensor information fusion should be human perception, recognition, and control system. However, since there is no clear engineering explanation for the latter, what kind of function is required for the robot sensor fusion system is still a vague concept. . It is believed that with the improvement of robot intelligence level, multi-sensor information fusion theory and technology will be gradually improved and systematic. At that time, the manufacturing efficiency of the manufacturing industry will be greatly improved.
