At present, the robot movement accuracy has developed from ± 10mm at the beginning to ± 3mm at the present time. This means that the robot can move more accurately in a wide range. "Wandering Earth 2" is one of the most popular films during the Spring Festival of the Rabbit. The future world it looks forward to is more rooted in the current industrial scene and the actual development of science and technology. It can be said to be a mirror image of real industrial production and social life. In countless imaginations of the future world, robots are an inseparable and important part of the future society. The industrial mobile robots that appear in many scenes of the film are made by Guangdong enterprise - Shenzhen Youai Zhihe Robot Technology Co., Ltd. (hereinafter referred to as Youai Zhihe). These robots do not only exist in science fiction films. In fact, they have been widely used in the current industrial production and life. They can be called "true colors" in movies. The robots in the film have been widely used in "Wandering Earth 2". Different types of robots appear in various scenes of the film: the inspection robot with a mechanical arm independently operates the monitoring indicators to ensure the life safety of the space station personnel; In the conference hall of the United Government of the Earth, robots are stationed to assist human scientific decision-making; In the data center of Beijing Aerospace Center, the inspection robot supports the smooth operation of massive data; In the planetary engine hangar, mobile robots move and transfer materials in an orderly manner... "We have 14 different types of industrial mobile robots in total in the movie, including patrol robots, industrial logistics robots, and so on." said Jian Jian, marketing director of Youai Zhihe, "In fact, the inspection robot in the film also undertakes important tasks in real life. Robots can be found in extremely complex environments such as offshore oil platforms, Gobi desert, offshore wind power platforms, and open-pit coal mines." "The industrial mobile robots seen in the film are flexible in action, and they are composed of two main technologies: laser SLAM fusion navigation+two-dimensional code combination." Key introduction, Their industrial mobile robot adopts laser SLAM integrated navigation mode, and the path planning adopts virtual tracking and independent planning. The robot will search an optimal route after comprehensive evaluation based on the prior map environment information and the real-time dynamic environment information perceived by its own sensors, and can avoid dynamic obstacles in the environment in real time. This technology is mainly applied to patrol inspection, operation and maintenance robots, and has been used in electric power, coal mine, steel, petrochemical and other fields. Why should we use industrial mobile robots? "In the power plant, the circuit of the high and low voltage distribution cabinet in the past was manually operated. Because of the danger of operation, two people must cooperate with each other, one reading the operation instructions and the other operating step by step, otherwise it is easy to cause catastrophic casualties due to improper operation." Key said that the robot can recognize the surrounding environment, control the error within ± 5mm, and can also move to the front of the distribution cabinet independently, Judge the position of the switch knob independently, instead of manually realizing the circuit on-off. Industrial mobile robots are not only not afraid of hardship, but also become the backbone of intelligent production in the semiconductor industry with the advantages of strong professionalism. Wafer is a high-cost semiconductor raw material, which is extremely fragile
