Abstract
To improve reliability and security of the aircraft fuel tank inspection and decrease labor intensity of maintenance personnel, an inspection robot is developed. Maintenance workers’ work, which include entering the fuel tank and inspecting defects and so on, can be performed by the robot. Approach of switching motion mode is presented based on wheel-tracked mobile mechanism in order to adapt to the particular structure of aircraft fuel tank. Wheeled mechanism and tracked mechanism can be switched to each other at some time. By means of remote control and wireless video transmission, the worker can operate the robot and observe the scenario of fuel tank conveniently. Experimental result shows that the work of the robot is stable and reliable, and the design is reasonable and feasible.
