This outdoor explosion-proof refueling robot can adapt to the working environment of plateau low temperature, high altitude and strong ultraviolet rays, and has high safety. For example, the arm span of the robot arm is short, resulting in a small range of motion, so it has high safety and high stability. In addition, we designed a double-arm structure, which enables the robot to complete complex cooperative actions and improve work efficiency. The R&D engineer told reporters that it is worth mentioning that the localization rate of the overall equipment of the robot has reached more than 90%.

So how does this robot work in reality? The reporter saw through the live video of the launch ceremony of the intelligent identification and gun-lifting technology of the refueling robot (test) of PetroChina Tibet Sales Company. The staff clicked on the app of the PetroChina Hospitality e-station to place an order for the robot to refuel, and the robot in the standby state was immediately "awakened". After using AI to quickly identify and accurately locate the fuel tank cap, two manipulators were extended, one to open the cap and the other to refuel, and the operation was completed in just a few minutes.

That is means from entering the station, refueling to exiting the station, the driver does not need to get off the bus, nor does he need to have any contact with the station personnel or objects such as fuel guns. The only action is to tap on the mobile phone to complete the order.

The position of the fuel tank cap is different for different models. How to accurately position the robot and smoothly open the fuel tank cap becomes the key. "This refueling robot adopts a 2D+3D vision combination, and improves the stability and accuracy of vision through 2D assistance and 3D precise positioning. The design of a movable platform on the device improves the robot's adaptability to the parking range. It can be raised, lowered and moved horizontally on the base to serve vehicles of different lengths and different parking positions, with an accuracy of up to millimeters. At the same time, the refueler and the oil gun adopt a one-piece flexible integrated design, which can adapt to the vehicle The slight swing will not cause damage to the vehicle's fuel filler and fuel gun.

In terms of mechanical structure design, the robot has gone through three iterations of prototypes. "Because it has not yet achieved mass production, the only refueling robot available now, Tibet is one of our pilots. This robot is the closest to our original design concept, and the actual use is relatively mild. At present, the refueling robot is a petroleum and petrochemical robot. In the new track in the field, few gas stations can achieve 24-hour self-service, and the refueling robot can work non-stop 7×24 hours, improving the work efficiency of the entire gas station.

"Actually, this model piloted in Tibet can be used in plain areas. What we need to do now is some technical processing for extremely cold regions and adaptation of special models in Tibet.

The reporter learned that, in cooperation with the use of the robot, PetroChina Tibet Sales Company has also developed intelligent identification gun lifting technology, adding special structures such as gun lifting identification and identity authentication on the basis of the original refueling gun to ensure that the gun is stopped when abnormally drawn. It can avoid the safety problem caused by the oil gun being separated from the fuel tank port during the refueling process. At the same time, through the linkage of the safe refueling control system, the emission of oil and gas during the start and stop of refueling is further strictly controlled, and the environmental protection capability is improved.

"The technology of refueling robots and intelligent identification of guns has been put into use in the plateau environment, providing consumers with a new consumption experience. It is an important measure for innovation-driven development strategy, mass entrepreneurship, and mass innovation decision-making." Energy Research of the Tibet Autonomous Region Science and Technology Department said the director of the central office. In the future, PetroChina Tibet sales will also be gradually promoted in gas stations in areas above 4,500 meters above sea level to further reduce the labor intensity of employees in high-altitude areas and improve service efficiency.
