[0002] In recent years, with the widespread application of biomedical and university scientific research technologies, and the continuous development of modern biomedical science, the demand for automated sample storage has become increasingly important. As an essential piece of equipment for automated sample storage, the demand for AGVs is also increasing.

[0003] Currently, AGVs on the market generally have two storage options. One is a built-in cryogenic storage device, where a robotic arm delivers the frozen boxes inside the AGV to the sample library's transfer window. The other is a direct transfer to a cryogenic transfer box, a sealed transfer tank that uses liquid nitrogen for storage. However, transfer vehicles compatible with both of these mainstream storage methods have yet to emerge. Sample libraries are expensive, occupy a large area, and purchased equipment may not be of the same brand. There is also the risk that the corresponding AGV transfer vehicles will not be able to accommodate sample boxes stored in multiple ways. Therefore, a solution is urgently needed.
