The robot, which combines intelligent systems and human factor engineering, is able to detect whether a person entering a building is wearing a mask. If not, the robot will ask the person to do so, the BGU said on Facebook. The robot can also detect whether the mask is worn properly with the nose being covered, and ask the person to wear it as required. Besides, the robot can also guide visitors to the desired location inside the building.
