In order to promote the application of substation inspection robots in the substation and the process of the unmanned substation, we put forward a layered hybrid architecture of power substation inspection robot by analyzing the requirements of the substation equipment inspection in detail. Moreover, the precise navigation positioning system, relia- ble power management system, and communication system are designed to fit the substation environment. At the same time, the detection system which can accurately identify the thermal defect and abnormal appearance and evaluate the sound anomaly of substation equipment is also designed. Then the reliability, safety, and feasibility of inspection robot are verified by the practical application. It is concluded that the power substation equipment inspection can adapt the complex unstructured substation equipment better, and the autonomous positioning navigation is achieved precisely with long-term energy security and reliable security communications. Therefore, the implementation issues of substation equipment＇s ac- curate recognition, inspection and the background analysis and diagnosis can be solved. The security and stability of the inspection robot should be ensured to perform the online monitoring tasks, which can meet the demands of inspecting substation equipment. Finally, some suggestions on the development trend and research of inspection robot are given.
