The robot is separated into several structures and can be moved to various locations to detect the body temperatures of different people. At the same time, it comes with a sensor which prevents itself from knocking over pedestrians and obstacles. Inside the trunk are the AI host, electric circuits, and batteries. Complemented with the 4K and thermal imaging lens at the top, the robot can accurately recognize human faces even when they are wearing masks. If the robot detects a person with abnormal temperature, it will keep a record of the image and issue alert to remind related staff to pay attention.
