Doctors diagnose（诊断）patients online. Robots help to send food to patients. Drones（无人机）monitor people in crowds. We are using new ways to fight the novel coronavirus（新冠病毒）. They are safe. They can help people keep in touch with each other. Let’s meet these high-tech（高科技）helpers!
Telemedicine（电子医疗）system
With remote（远程的）video system, doctors can diagnose patients without seeing them in person. Also, doctors from different hospitals can have a meeting by using the system at the same time. This saves a lot of time. Both Huoshenshan and Leishenshan hospitals have this system.
Drones warn people in groups
In some faraway places, police use drones to monitor people in groups. When the drone finds big groups of people, police will warn them through the loud speaker on the drone. In some places, people also use drones to disinfect（消毒）their communities.
3D “hospital”
A company in Shanghai printed 15 rooms by using 3D technology. They sent the rooms to Hubei for patients to live in. Each room is about the size of your bedroom. A 3D printer takes 24 hours to build the rooms.
AI（人工智能）system checks for fever
At the Mudanyuan subway station in Beijing, an AI system can check people in crowds to see whether they have fevers. When people pass by, the system scans（扫描）people’s faces. The system can check about 300 people in one minute.
Smart robots
Time to eat! In some hospitals, smart robots help to give out food to patients. The robots can also help to hand out medicine and show the way to people.
