Devices, including robotic devices, operating in viscous fluid flow can use passive sensor data collected to represent fluid parameters at an instant in time to derive information about the flow, the motion and position of the device, and parameters of the physical system constraining the flow. Using quasi-static analysis techniques, and appropriate feature selection for machine learning, very accurate determinations can be made, generally in real time, with very modest computational requirements. These determinations can then be used to map systems, navigate devices through a system, or otherwise control the actions of, e.g., robotic devices for clean-up, leak detection, or other functions.

A detection method used for a fuel tank, comprising: receiving a result of determining whether a constant-speed refueling condition is satisfied (S100); if determined that the constant-speed refueling condition is satisfied, then receiving detection parameters collected from a refueling terminal by means of a sensor according to a preset frequency (S102); and inputting the detection parameters into a preset shape determination model, and determining the shape of a staged fuel tank (S104). Thus, the technical problem of poor fuel tank metering management that is caused by the inability to detect different types of fuel tank shapes is solved.
