China may have finally turned a corner in its fight against the coronavirus, and it has robots to thank for helping it do so.

Throughout the coronavirus pandemic China has issued cutting edge technology in an effort to combat the virus. Early on Chinese authorities used AI-driven robots to scold people for being in public without wearing masks, while companies worked on using drones to deliver medicine and supplies to patients without endangering healthy people.

As China has continued to fight the pandemic, robots continue to play a significant role in the ongoing efforts to contain the spread of the virus. According to All About Circuits, in addition to the robots scolding people for not wearing masks, authorities are also relying on robots that scan crowds for raised temperatures, one of the earliest symptoms of infection. The robots “include high-resolution cameras and infrared thermometers that are capable of scanning the temperatures of up to 10 people at once who are in a radius of 5 meters. If one of these robots discovers somebody who is not wearing a mask or who has a high temperature, an alert is sent to the authorities.”

China’s success with robots is only possible due to a combination of 5G, AI, edge computing, cloud computing and IoT. The end result are robots capable of interacting with people in a way never before seen. As All About Circuits highlights, that interaction can be eerily lifelike:

“You there! The gentleman wearing a red coat holding an umbrella in your left hand—yes, you. You are not wearing a face mask, please put one on immediately. If you do not have one, come to the police car and we will provide you with one.”

With robots finally beginning to deliver on the promise proponents have long held out, it’s little wonder Microsoft, AT&T, Google Cloud and Verizon are all working hard to capitalize on the emerging technologies.
