Abstract: Disclosed is a patrol robot, including a robot body and a control system disposed on the robot body. The robot body includes a chassis system and an accommodating cavity disposed on the chassis system. The control system includes a main control module, an image processing module and an image collection device. The main control module is electrically connected to the image processing module. The image processing module is electrically connected to the image collection device. The image collection device includes a ball-type camera disposed on the accommodating cavity. The image processing module includes a behavior recognition unit. The behavior recognition unit recognizes pedestrian abnormal behavior according to an ambient image collected by the image collection device to generate pedestrian abnormal behavior recognition information, and the main control module transmits the pedestrian abnormal behavior recognition information to a patrol robot management system.
