Description

Technical Field

[0001] The present application relates to the technical field of underwater robots, and in particular to an adaptive matching system and an underwater robot. Background Art

[0002] When an underwater robot or underwater intelligent device needs to connect to a load unit with different working voltages, it is often necessary to use multiple watertight interfaces with different voltages to connect to load units with different signals and different power levels, thereby providing the corresponding voltage for the load unit. For example, for the same RS485 communication, the manipulator requires a power supply voltage of 12V, and the water quality sensor requires a power supply voltage of 5V. At this time, the sealed cabin of the underwater intelligent device needs to open two watertight interfaces to respectively cope with the manipulator and water quality sensor with different voltage level requirements. However, this will increase the watertight interface and power supply circuit, and will directly lead to an increase in material and processing costs; moreover, the increase in the number of watertight connectors will directly increase the risk of water leakage and seepage in underwater intelligent devices.
