The development of new technologies, which include advanced sensors and the application of artificial intelligence, has led to the moment that some operations done by workers can be changed in the maintenance domain. Visual inspection is one of the operations that will be changed in the future. Today, there are various legal regulations regarding the maintenance and control of vehicles in the transport sector, which cause additional costs for operators. There is a need to reduce those costs by integrating autonomous robots for the visual inspection of various vehicles. In addition to reduced costs, the benefits are reflected in improved human safety, greater efficiency, and reduced errors during the visual controls. This paper explores various applications of autonomous robots in various transport domains, including rail systems, road and bridge networks, aerospace, and maritime industries. It also shows a real example of visual control of locomotive undercarriage in railways.
