Technology And Application Of Hospital Logistics Robot

AGV logistics robots first appeared in the 1950s, and began to be popularized and applied in the industrial fields of developed countries such as Europe, America, and Japan in the 1970s. At present, it is still in the application and promotion period in China, and it is mainly used in the field of factory logistics and warehousing logistics. When industries such as automobiles and e-commerce are fighting endlessly for AGV logistics robots, hospitals are becoming another popular field for the application of AGV logistics robots after industry and e-commerce.

At the Ninth China International Robotics Summit Forum, Hu Bin, the product director of Mumu Robotics, introduced to us their company's main product - Noah.

How does the Noah hospital robot work in real life? In Shanghai Children’s Hospital, Mumu has a robot team responsible for the delivery of medicines in the entire inpatient department. PVAS infusion, as we all know, especially in Chinese hospitals, there are more infusions. Unlike foreign hospitals, their infusion volume is relatively small. Chinese infusions The volume is very considerable. Each patient receives an average of four bags of infusion per day. There are a large number of people in the hospital who are responsible for the infusion. In the Children's Hospital, all are served by Noah robots. Noah robots can independently complete elevators, open and close doors, and Send it to the nurse station, and each nurse station in the ward has its own independent ID, which can connect with the hospital and scan through the PDA. This process can complete a time, place, which nurse completes what certification, and the entire material All the information in the transportation chain has been obtained. Compared with the previous manual distribution, it will be improved in terms of informatization and security. In the hospital, everyone likes the children's hospital very much. The children are crying and crying in the hospital. It is very happy to see the robot children in the hospital. And each employee has his own employee card, and we control the entire loading and picking tasks through different permissions.

application scenarios

In the hospital, a large amount of materials are delivered every day. What I just talked about is one of the infusions. Usually, the hospital is similar to a small distribution station. In the hospital, doctors and nurses wear white clothes, and many of them wear blue clothes. delivery. In response to the shortage of labor, various mechanized logistics methods have emerged in hospitals. Before robots, such as pneumatic transmission, but this kind of transportation can only transport some urgently needed medicines or small items, followed by rail trolleys and box logistics. , this volume is larger than that, and finally the vertical well is mainly used in the operating room.

The emergence of robots has basically solved the previous pain points of various types of logistics and warehousing. The manual labor is mainly manifested in the lack of labor. In the case of pneumatics, the main reason is that the transport body is too small, of course, the uniform speed is fast, and the starting pressure is very fast. At present, pneumatics are mainly used in standard scenarios. Other transportation methods are suitable for small batches of medicines. Although the track and box type have a certain magnification, the number of kilograms is still not enough. Some workers in the hospital push materials that are very large, and the mechanical weight reaches 600 kilograms. , so the hospital logistics robot basically solves the common situation in the hospital.

product description

Hospital logistics robots should be regarded as the first unmanned driving category in terms of division. The main cooperation technology of Mumu Robot is also released around unmanned driving. Commonly used areas include doors, emergency rooms, medical technology buildings and inpatient wards. same scene problem.

Hu Bin said: The hospital is a very vertical industry, and this scene is very detailed. When we go to the hospital, we will find that every hospital and every transportation link is a vertical field scene. All kinds of robots are only the second and third generations, which are divided into four series, Noah's first series, second series, third series, and fifth series. Among them, the second and third series are mainly products, but they are all the same and are produced separately Different transport scenarios work. The latter series will be launched at the beginning of next year, and the fifth series will be launched by the end of this year. The difference is that the first series is made in large batches, very common like those in factories, with a length of about 1.5 meters and a load capacity of 500 kg. The five series is very small, but the speed is very fast, and it is mainly used for emergency delivery. We know that some patients need to be checked as soon as possible because of the condition of some patients.

The function and value of Noah lies in the independent development of multiple robots to achieve complete output. This is the coefficient of the entire work structure including the cloud. A robot boss, all robots are controlled by the intelligence of this robot, including cloud systems and three-dimensional traffic regulations. At the beginning of the factory construction, AGVs were considered, and the factory environment would be deployed around AGVs, but the hospital was different. When the hospital was built, it was not considered that the hospital was built to serve robots, but to serve patients. However, when a company goes to a hospital to do business, it needs to adapt to the hospital. The hospital depends on each distribution link. At present, there is no hospital that has opened a special topic for robots.

In fact, hospital logistics robots can also be regarded as building delivery to a certain extent, and Chinese hospitals are very crowded, including many hospital beds on the passages, and there will be a lot of strange medical equipment. How do robots use lasers to avoid these obstacles? Wood company has been researching.

At present, the navigation and obstacle avoidance system used by Mumu robot is version 3.0 of this system. It can recognize the environment of the hospital through vision, and combine the common equipment in the hospital, such as infusion poles, hospital beds, carts, and operating rooms. For modeling, laser SLAM and VSLAM are fused together to make a container SLAM, which is a process after 3D reconstruction. What should I do if I encounter a common three-dimensional hospital bed or a robot?

You must know that this is a bed, and whether it is a robot or some common chairs, stools, etc., the requirements for absolute budget are very high. For hospital logistics robots, they often face odd-shaped things, and they can see the whole real face by observing the model matching a little bit. This is a fusion of vision and lasers, analyzing human legs, and seeing how robots interact naturally with humans in the crowded environment of the hospital. At the same time, Mumu Robot is still working on a RUP algorithm, which is also a kind of predictive control. In layman's terms, when people walk towards each other, they don't say that they walk in front of each other and then go around when they meet each other. Everyone will naturally look at each other and know whether you are going left or right if you are ten or twenty meters away. The Mumu robot hopes to achieve a more natural interaction by analyzing the gait orientation of people to predict whether to go left or right.

There are more than 40 units of the entire multi-machine matrix dispatching system, which takes into account the dispatching problem in complex situations. Multi-robot delivery of medicine, how to assign multi-robots in the scene, including when to go to work automatically, and then jumping to another scene to go to work during the physical examination is all controlled by the complex scheduling matrix system in the background, not including all monitoring system. This scheduling system is a part of management. Mumu's management background can be opened to users, and they can see all the status inside, including the single status and vertical status, and can plan the job responsibilities of each robot.

In the design of the hospital-wide distribution plan, one part is the inpatient department, the other part is the outpatient department and the emergency department and medical technology. This is similar to the state of the hospital. We basically divide the hospital into three parts. When it comes to the inpatient department, there are three typical scenarios. For example, there are housing in the outpatient and emergency department, and the operating room is open and closed. The inpatient department uses different robots to complete different delivery tasks.

Automatic loading and unloading

This is a transportation process. PIVAS transportation includes personnel dispatching, automatic car dispatching, access control, notification system, nurse unpacking, clinical use, empty box recycling, and next use. The robot body technology is part of it. The hospital is subdivided into each scene and it is more vertical. For example, the robot that transports drugs, the control of narcotics and drugs is stricter. It was handwritten and handwritten before. Some mechanisms have been made, but there are still some risks. If you start from the hospital Sneaking out is a drug, which is very strict for national control and control. In recent years, many narcotic drugs have been controlled similar to cabinets. The combination of robots and cabinets, and the drug cabinets carried by robots, are made. From transportation and control of narcotics and narcotics, each drug can be precisely controlled. I need to know who put the drug and when it was taken, including the recovery of the drug after it is used up. There is a special scanning place, including recycling The poison and narcotics can be recycled after the mouth is used up. This is a necessary small piece of transportation. It may be very small and scattered through the five-series system later, and it is not on-call in batches.

There are domestic waste and medical waste in the hospital, and the medical waste needs to be weighed. Every scene is different. There is also a disinfection and sterilization robot. At present, using American technology, the disinfection and sterilization can be completed within three minutes, which can target common Microorganisms and bacteria are effectively killed.

At present, Noah has served more than 40 hospitals. Hu Bin said: Mumu robot is also the most prepared for transportation scenarios in this industry, and it has transportation in many hospitals in different scenarios.
